When renovating both residential and industrial premises, the choice of paint for radiators is especially important. It should be said that painting heating radiators not only performs an aesthetic function, giving them a presentable appearance, but also reduces the harmful effects of corrosion. In addition, the existing variety of colors and shades will allow you to paint the radiator so that it blends harmoniously with the intended interior.
The wrong choice of paint and varnish material can lead to the fact that when the radiators are heated, the room will constantly be filled with a pungent and unpleasant odor. To prevent this from happening, you should choose heat-resistant compounds that do not emit unpleasant odors and do not turn yellow when heated frequently. It is better to buy paint from well-tested brands, a little more expensive, but also of higher quality. This will significantly extend the life of the radiator.
In order not to make a mistake in your choice, before starting work you should study the basic properties and types of paints and enamels for radiators. According to existing standards for residential premises, paint for radiators must be odorless, non-toxic, resistant to temperature changes and withstand light mechanical damage. Heat-resistant enamels are made from a varnish solution, colored pigments, with the addition of various fillers, depending on the required properties. The latter components, in turn, affect the purpose of the paint. For example, adding organic resin to fire-resistant enamel helps to increase the complete drying time, but makes it more elastic and has a positive effect on the quality of protection.
Such enamels are used for painting concrete stoves and metal pipes, oil refining and oil production equipment, and much more. Heat-resistant enamels can be used both on concrete and building surfaces, and on metal, including wires and cables.
The most optimal options when choosing paint for radiators can be considered the most common types of heat-resistant paints and enamels on the market. Alkyd paints, manufactured using the latest technologies, have high strength and a uniform layer structure when applied. They can be used at temperatures no higher than 150 degrees. Alkyd paints for radiators have an unpleasant odor, which disappears within a week after painting.
Acrylic paints for batteries heating is odorless and can withstand up to 80 degrees. These paints are only available in white, so to achieve the desired color you must use a dye. The low price of these paints makes them affordable and, therefore, one of the most popular.
Silicone-aluminum paints for radiators can withstand temperatures up to 500 degrees. Their service life can reach five years without re-coating. Such paints are quite expensive.
Aluminum paints with heat-resistant varnish, popularly called “serebryanka”, contain petroleum products, so they cannot be considered environmentally friendly. They have an unpleasant odor and do not dissipate for a long time. It is advisable to use them in non-residential premises.

We also have the opportunity to offer profitable delivery not only within the city, but also throughout the Moscow region.
Over time, old batteries lose their aesthetic appearance, rust appears, cracks appear in the coating, and paint peels off. Agree, changing the radiator in this case is not the best idea. It is much easier, faster and more economical to repaint the battery. Moreover, it is quite easy to update the appearance of the heating device.
We will help you choose the appropriate enamel composition, explain how to prepare and how to paint the heating radiator correctly. We will also outline the nuances that should be taken into account when working with different types of radiators.
The proposed photo ideas will inspire you to choose an interesting solution and implement your design idea.
It is not always possible financially, and in many cases even technically, to install a new radiator. It is easier to refresh the outside of the heating device if it is still capable of serving. If the battery has already had to be repaired or does not heat well, then it is better.
The painting process as such is not particularly difficult, but this does not mean that you can buy any composition and immediately begin restoring the attractiveness of the radiator.
The paint must be selected according to certain parameters, and the battery must be carefully prepared. If this is not done, the new coating will not last long, and you will soon have to repeat the process again.
An old cast iron battery with peeling paint looks very unaesthetic. In addition, the material of its body is subject to oxidation and rusts.
When choosing a composition, it is best to focus on options specifically designed for heating devices. But if there is no such inscription on the label, you should carefully study the instructions and find data on its heat resistance.
Requirements for paint coating:
- Heat resistance. The composition applied to the radiator body must withstand temperatures up to 80-90 degrees and be flawless for the time promised by the manufacturer.
- Adhesion. It is necessary that the composition has good adhesion to the surface to be painted. Did not peel off when heated and alternating heating/cooling.
- Corrosion protection. The composition must contain anti-corrosion substances so that the coating in direct contact with the body does not cause its destruction.
- Color fastness. Unconditional condition, because Radiators are painted for aesthetic purposes, among other reasons.
- Abrasion resistance. From direct contact with various furnishings, drying items, etc. the coating should not become thin.
- Safety. It is very important that the composition does not contain any components harmful to health.

An integral role in the arrangement of any living space is invariably played by such important communications as the heating system. The devices that are part of it can not only heat the air in the room, but also form part of the interior, while a well-designed radiator will become a real decoration of any living area.
However, old batteries with peeling paint are unlikely to be able to decorate the house in any way, so the owners find a solution to this problem by replacing old equipment with new ones. This method is quite effective, but also very expensive. Therefore, it will be a much more reasonable decision in terms of savings.
It is worth noting that in the process of deciding what paint to paint heating radiators, you should opt for special compositions intended specifically for such structures. Their use will protect the surface of the radiator from corrosion and provide the unit with an aesthetic appearance. If previously it was customary to cover the functional parts of the heating exclusively with white compounds, today the materials for painting have a wide variety of shades, so choosing the option that will best suit the interior of the room being furnished will not be difficult.
What determines the choice of paint for batteries?
To figure out which paint is best for painting batteries, you should remember that the quality of the composition used directly depends on the final result of the work. 
Special requirements for paint for heating appliances include the following:
- resistance to high temperatures (at least 100°C);
- resistance to aggressive environments;
- wear resistance;
- absence of any harmful released substances.
To decide what to paint radiators with, you should study all the types of compositions used for these purposes. These include:
- Acrylic enamels. Their production is carried out using solvents of organic origin, as a result of which during the drying process a characteristic and not very pleasant odor appears. However, such paints have a glossy shine that will not disappear even after many years of use.
- Alkyd enamels. Such compositions are very resistant to high temperatures and are wear-resistant. In addition, you can always choose the desired shade, since these paints are available in a rich range of colors. The main drawback of these enamels is the unpleasant odor, which not only persists for several days immediately after painting work, but can also reappear when the radiator is overheated.
- Water-based paints. This option is considered optimal among consumers, since this odorless paint for batteries dries very quickly (more details: ""). However, when choosing such a composition, it is very important to pay attention to its packaging, which must include information about the possibility of applying such paint to elements of the heating system. High-quality, odorless paint for radiators cannot be cheap.
Thus, we can say that the only odorless battery paint is water-dispersion, so it is this material that you should pay special attention to.
Less often today, oil-based paint is used, since such a composition has become obsolete over time and has given way to more modern paint and varnish products.
Preparation before painting radiators
It is important not only to decide which paint is best to paint the batteries, but also to carefully prepare the desired surface for processing. An important fact is that the preparatory activities themselves take much more time than the process itself. The procedure should be as follows:
- The surface of the radiator must be thoroughly cleaned, removing old paint from it and cleaning areas with rust. Dust and dirt should also be removed with a cloth.
- Next, you need to apply a solution to the battery to wash off the old coating, and then cover it with a film to soften it. Next, the paint can be easily removed using a construction spatula or a grinding machine equipped with (read: “How and how to remove paint from a heating radiator - means for removing old paint before painting a radiator”).
- After this, the already cleaned surface is sanded with sandpaper and degreased using any solution with a small amount of alkali.
- A primer with anti-corrosion properties is applied to the already cleaned surface, which not only prevents the appearance of harmful formations, but also increases the adhesive properties of the paint. It is best to use an alkyd primer for these purposes.
In the process of choosing what paint to paint batteries with, you need to remember that the modern construction market offers a wide range of these products, which already include a primer and a plaque-removing solution. The particular convenience of such mixtures is that they can be applied immediately, without carrying out all the above manipulations with the battery. 
The process of painting a heating radiator
Having finally decided on what paint to paint the radiators with, all actions should be performed in accordance with the following order:
- Initially, you need to protect the floor from contamination by covering it so that paint stains do not fall on it. Unnecessary paper (for example, old wallpaper) or fabric is perfect for these purposes.
- Then you should choose brushes that have soft bristles. In this case, one of them should have a straight shape, and the other should be curved so that paint can be applied to the most inaccessible areas of the radiator.
- You must first apply the coloring composition at the top of the battery, gradually moving towards its bottom. At the same time, do not forget that you need to paint all areas of the radiator, starting with the internal ceilings and ending with the external ones. This is done in this order so as not to accidentally stain your clothes or hands. After the first layer of the composition has dried, you need to apply the second. Experienced craftsmen recommend: regardless of what paint to paint cast iron batteries or batteries made of another material, it would be much more correct to apply two thin layers rather than one thick one, since in the first case it will be possible to ensure uniform paint coverage.

The painting itself can be done using a special spray can or using a spray gun. By performing all the above steps in exactly this sequence, you will be able to achieve a perfectly flat and smooth surface of the radiator, and the applied paint itself will last a very long time (read also: " "). The main thing is to choose the right composition that will be most suitable for a specific heating battery.
If necessary, you can always study various photos of color options for these devices in order to best choose the desired color scheme for yourself. Tips for painting radiators in the video:

What are the types of compositions?
The modern coating market offers many options:
- alkyd;
- hammer;
- acrylic;
- silverfish;
- water-based;
- silicate;
- powder
Alkyd enamels have good resistance to heat, and acrylic enamels give the surface of heating radiators a glossy shine.
A certain type of material is suitable for a specific type of radiator. Batteries are made from various types of metal. Their painting requires compliance with certain nuances.
Alkyd enamels
This type of coating is considered acceptable for covering radiators. Alkyd paint has a number of advantages:
- heat resistance;
- creates a glossy finish on radiators;
- long service life;
- wear resistance;
- high quality.
The main disadvantage of this coating is its unpleasant odor. This is due to the presence of white spirit in alkyd materials.
The smell after applying them to the battery lasts for several days. It may appear for a while when the radiators heat up. Another disadvantage of this material is its long drying time.
Alkyd enamels are made on different bases. This could be the basis:
- silicon-organic;
- organic;
- water
Much depends on the color of the colorful product. When choosing a white alkyd enamel, it is recommended to choose a product that contains a titanium-based pigment. Thanks to it, the material will not turn yellow during battery operation.
Acrylic colorful products
Acrylic enamels have advantages over alkyd enamels. They are as follows:
- no odor;
- quick drying period (within 2-3 hours);
- Possibility of application to hot batteries;
- special consistency that simplifies the process of application to the heating device.
Any acrylic paint requires preliminary preparation before applying it to the battery. The surface of the heating device must first be primed and allowed to dry.
The product is applied in several layers. The advantage of the product is its special consistency, reminiscent of sour cream. When painting, the colorful material does not spread.
The surface of the heating device must not be wet. Acrylic enamel does not tolerate moisture.
When applied to the battery, it resembles plastic, which looks organically in the interior of the apartment.
Acrylic enamels have their disadvantages:
- rather short service life and high probability of shedding;
- color change after drying.
Hammer
Hammer colored products are characterized by one feature - with their help it is possible to obtain several shades from the same color at once. Hammer paints allow you to achieve various texture options on heating devices.
This type of paint material creates a non-uniform coating on radiators. It smoothes out imperfections and uneven surfaces of heating radiators.
Hammer paints are applied to rough surfaces.
To do this, you will need to pre-treat the heating radiator with sandpaper. Otherwise, the products are applied to devices according to the same scheme and rules as other types.
Water-based
It is allowed to paint heating batteries with water-based paints. The main arguments for using this type of paint coating are:
- their resistance to high temperatures;
- quick drying on the surface;
- odorless paint.
The main argument against the use of water-based paint materials is their low wear resistance. According to this criterion, they are significantly inferior to more resistant species.
Powder
Powder coating of radiators has become an alternative to the use of traditional liquid paint materials. The process of applying powder paint to a battery requires compliance with a number of important conditions:
- the dry powder mixture is poured into a special gun and sprayed onto the heating device;
- an electric field arises, attracting colorful particles, where charges of the opposite direction are created;
- The applied paint needs to be polymerized, for which a special oven or heat gun is used.
To ensure high-quality application of such a colorful product on a heating device, in some cases, ultraviolet radiation is required. To create it, you will need an ultraviolet lamp.
Powder paints for radiators undergo three melting stages when applied:
- acquisition of viscous consistency by powder;
- formation of a single layer of melted powder particles;
- The heating device is wetted with the molten polymer.
Painting a heating radiator in an apartment
When choosing paint, you need to take into account the type of room. If the place is public, an office, then you can use cheap materials
When renovations are carried out in a city apartment, odorless paint is required, and this is especially important if the renovation work is planned in a children's room.
Many people use conventional paint materials for painting pipes, which are designed for working with floors, walls, and ceilings. This is not the best option. They are not suitable for use at high temperatures, so they spread quickly and acquire a yellowish tint on the surface.
If you have to choose between glossy and matte paint materials, then you need to take into account the fact that a shiny coating always attracts attention and all the flaws, unevenness and other shortcomings of the radiator will be visible. The matte light coating will quickly turn gray because dirt accumulates in the porous structures
We paint batteries with our own hands
More often they prefer to choose a colorful material for radiators that is white. This is no longer relevant. Previously, there was no such abundance of materials as there is now. White radiators look beautiful only in rooms where the walls are made in light colors. It is better to choose a paint color that matches the color of the walls and the entire room.
Knowing all types of paints, their features and application rules, all that remains is to get to work. The main thing is that the work is carried out in a good mood, and then the repairs carried out will delight you with their aesthetic appearance for a long time.
How to paint types of enamels for cast iron radiators
Heat-resistant enamels for cast iron batteries are produced resin based(alkyd, acrylic, silicone), aqueous dispersions(acrylic and silicone), there are also powder paints, but their use requires special equipment; painting is done in a factory.
For painting at home with your own hands, acrylic compositions (water-soluble or organic solvent-based) and alkyd are popular.
Alkyd
Alkyd-based enamels contain pigments, special additives, and a thinner - pentaphthalic or glypthal varnish. Common alkyd enamel - pentaphthalic PF-115. The compositions are affordable, have good coverage, are durable, wear-resistant, and have a wide range of colors.
Photo 1. Alkyd enamel for cast iron heating radiators with a plastic effect from the manufacturer “Tex”.
Lack of enamels - drying time and unpleasant odor, which persists indoors for several days, can appear at high coolant temperatures; enamel cannot be called harmless.
Reference! Alkyd enamel apply in 2 layers onto a pre-primed surface with a brush or spray gun.
Water-dispersible acrylic
Water-based acrylic enamel dries quickly, the paint layer is smooth and even, like plastic. It has no smell, does not burn, safe and environmentally friendly, has high adhesion to metal.
The disadvantage of acrylic water-dispersed enamels is instability to abrasives(the surface cannot be cleaned with powders).
Photo 2. Acrylic glossy enamel for cast iron batteries PROFI VD-AK-1179 dries quickly and leaves no odor.
Acrylic with solvent
In addition to acrylic resin, the composition includes pigments, additives and solvent - White Spirit. The enamel forms a durable and stable coating; the paint can be applied to surfaces previously treated with acrylic or alkyd. Layer durable, does not yellow with time.
The disadvantage is the unpleasant odor and drying time - painted surface dries in about 8 hours, the second layer is applied in a day.
Radiator paints and necessary tools
- Radiator paints and necessary tools
- Preparatory work and process of painting batteries
Many people believe that only the front part of heating radiators should be painted, but, unfortunately, this conclusion is erroneous.
Often, especially with Soviet batteries, rust spots begin to appear, and if they are not eliminated, the corrosion can spread further.
Good paint will help get rid of unwanted corrosion. To find out what paint to paint radiators with, you need to find out the characteristics of this product.
The purchased paint must be resistant to elevated temperatures, because radiators get very hot in winter, and maintain a natural color for a long time.
To choose the right paint and varnish material, you need to know what types are available for sale.
Acrylic paint has a natural color over a long period and is famous for not having a strong odor.
This option is well suited for painting radiators in winter, because you don’t really need to ventilate the apartment.
Alkyd paint has high temperature resistance and is therefore ideal for radiators. One of the disadvantages is the increased smell, so it is better to use it in the warm season, and not during the heating season.
There is another type of acrylic paint that is used in conjunction with a solvent. This material has good performance, firstly, the paint can be used without additional primer, and secondly, the coating has a good appearance and a glossy surface.
The well-known oil paint used to be a popular product, but with the development of the technological process it faded into the background.
This is the main list of paints and varnishes for cast iron radiators that can be purchased. For panel radiators, you can use aerosol paints (preferably auto enamel).
It is no longer fashionable to have white batteries, so do not be afraid to experiment with colors, the main thing is that the coating fits into the design of the apartment.
In a children's room, you can decorate radiators brightly, especially panel radiators, on which you can reproduce the entire landscape.
So how to paint radiators and in what style is up to you.
But it should be remembered that in order for the coloring material to adhere well, you must have a special tool, such as:
- sandpaper for pre-cleaning;
- a sharp object or knife to remove old paint;
- several types of brushes;
- small roller;
- unnecessary rags for cleaning the room.
This entire set will be needed for high-quality work and will help transform old and ugly radiators into a luxurious piece of furniture.
Selection of coloring composition
Painting pipelines and heating radiators is a responsible job that poses the question to the contractor: how to paint these parts? For painting, you can only use compounds that protect the metal from rust and are resistant to high temperatures. Central heating radiators heat up to a temperature of 60-80 degrees Celsius. The paint for a heating radiator should not change its original color when heated, peel off from the surface, collapse, or release toxic substances into the air.
It is necessary to select paint based on the radiator material
Advice! After painting, an unpleasant odor remains in the room for a long time. Odorless battery paint makes it possible to carry out work even in a residential area.
- acrylic;
- alkyd enamel;
- water-dispersed;
- silicone-based paint for radiators;
- based on heat-resistant varnish.
Acrylic enamel for radiators is designed for temperatures up to 80 degrees. When dry, it forms a glossy surface whose color lasts for a long time. This paint for heating pipes is odorless, so it is suitable for work in residential areas. The basis of this composition is white enamel, to which the required amount of pigments is added.
Alkyd enamel for radiators contains organic solvents. The strength of the enamel coating is higher than that of acrylic compounds. It evenly covers the surface and is resistant to temperature influences. The disadvantage of alkyd compositions is a peculiar unpleasant odor that can remain in the room for a long time even after drying.
Advice! If you have chosen alkyd compounds to paint heating radiators, opt for dark shades. Light pigments (especially white) that make up these enamels lose their brightness over time and turn yellow.
The question often arises: is it possible to paint radiators with a water-based composition? It is possible and necessary! This odorless metal paint is suitable for heating pipes and radiators in residential premises.
Painting pipes and cast iron heating radiators with two-component enamels, consisting of heat-resistant varnish and metallized particles, has become popular. Such compositions give the batteries shades of gold, silver, bronze, and with their help you can stylize radiators in an “antique” way. The advantages of these products include low cost and durability of the coating.
Zinc metal paint is also suitable for painting metal batteries. It will not only update the appearance, but also, thanks to its anti-corrosion properties, will extend the life of the radiator.
There are a huge number of multi-colored paints on the market for any type of material.
The choice of color depends on the preferences of the residents. Painting batteries white has long ceased to be relevant. Thanks to the range of paints, it became possible to paint radiators to match the color of the interior or, conversely, with bright colors. For example, in children's rooms, radiators in all colors of the rainbow, decorated with butterflies, flowers, etc. will look organic.
Coloring compounds for heating radiators can be produced in the form of aerosol cans. They are easy to use, allow you to evenly paint even hard-to-reach areas of batteries and significantly reduce the work time.
Review of paints for radiators
The most common options are enamel paints
. They can be acrylic or alkyd. The first ones were created using organic solvents. They allow you to create a beautiful, glossy finish. The latter are very durable, easy to clean, and practically indestructible. Alkyd enamels also have a huge advantage - a wide range of colors. Their disadvantage is that they include white spirit, which has a strong odor.
Traditional paints and varnishes containing harmful substances are gradually being phased out. Although they are quite effective - they give a long-lasting color, are applied evenly and are durable. In addition, the cost of such materials is affordable.
However, they can be replaced with more environmentally friendly materials - the same water-soluble paints
. They are absolutely safe, dry quickly, apply smoothly and do not emit carcinogens. However, when purchasing, you should be careful - not all such products are suitable for use, since water causes metal corrosion. It is better to choose acrylic-based paints, keeping in mind that radiators will still require careful surface preparation. The disadvantage of these materials is also that they are not wash-resistant and can stain the curtains.
Alternatively you can use enamel in spray cans
, intended for radiators. Although it is not entirely safe, it can get the job done in a matter of minutes. True, it will only allow you to refresh the surface without penetrating into hard-to-reach places.
Choosing what paint to paint batteries with is not difficult. When purchasing, you just need to make sure that it is designed specifically for radiators. This must be indicated on the packaging.
Required tools and materials:
- small brushes with soft bristles or a foam roller;
- for hard-to-reach places you need to take brushes with a curved handle;
- drill with an attachment in the form of an iron brush;
- sandpaper;
- film;
- putty knife;
- paint, primer, solvent.
Need to update
The service life of radiators made of cast iron or aluminum can exceed 50 years, but if the paint on old radiators in an apartment or kitchen has faded over time and began to swell, then in such an unpresentable form they clearly attract attention and can hardly be considered a home decoration. .
Solving the problem by replacing batteries due to the considerable cost of this method can hardly be considered the best option. And repainting the radiators can be a completely acceptable way out of the situation.
There are several factors to take into account:
- Not all types of heating radiators can be painted on your own at home. Often, especially if the dye is chosen incorrectly, it will either quickly turn yellow or peel off soon.
- Batteries, as you know, are made of cast iron, aluminum, steel, or can be bimetallic. In principle, painting cast iron radiators does not cause problems. Here everything depends only on the right choice of paint for this purpose. But in the case of aluminum radiators, convectors or batteries made of stainless steel, the situation looks different.
Such elements of the heating system are powder painted at the manufacturer, followed by heat treatment.
Therefore, applying a new layer of paint over the factory paint coating at home becomes a serious problem.
- The vast majority of manufacturers of heating radiators not made of cast iron consider attempts to unauthorizedly paint batteries as a violation of the factory warranty by the consumer.
- After drying, enamel dyes cover the products with a durable and monolithic layer, completely eliminating the penetration of air to the metal surface. If oxygen does gain at least slight access through the paint layer, then the protection of the metal product from corrosion should be called into question, whereas precisely the protective functions in most cases are the main reason for the painting of radiators.
- It is curious that the passports for all heating batteries contain a categorical prohibition that does not allow painting over the air outlet hole on the automatic air vent. That is, if you apply paint to this hole, then if necessary, it will be almost impossible to bleed air from the heating system. This circumstance must be taken into account when performing painting work.
- Aluminum and stainless steel radiators are painted in the factory with powder dyes, which, after application, are subjected to heat treatment at high temperatures in special boxes. It is clear that creating such technological conditions at home is not possible. Conventional oil and other dyes, due to their low adhesion on aluminum and steel surfaces, will not last long.
- Reliable painting of aluminum requires special equipment for this purpose, as well as the use of epoxy primers and enamels, which is very expensive. In addition, deviations from the technology will inevitably lead to peeling of the newly applied coating. There is also a method of anodic oxidation, but it is associated with significant technological difficulties and requires certain knowledge.
- If the consumer has successful experience in painting a car body and paint materials suitable for the task, then you can try to paint aluminum batteries. But otherwise it is better to abandon this idea. In this case, it is more advisable to buy new heating elements, or cover the peeling products with a decorative screen.
- A special point are steel convectors. They are equipped with frequent fins made of steel plates strung on a pair of pipes - the so-called “comb”. If you try to paint these plate fins, you will have the undesirable effect of a sharp decrease in heat transfer. It is also impossible to reach the pipes themselves with a narrow brush. Therefore, it is better to avoid painting these surfaces.
Such radiators are usually equipped with iron shutters and side screens. These elements not only can, but also need to be painted, and ordinary heat-resistant dyes are quite suitable for this purpose.
Types of paints for batteries
Today, many manufacturing companies offer a fairly wide range of products such as odorless paint for radiators. Thanks to this, buyers have the opportunity to choose the most suitable type for themselves:
- Acrylic enamel;
- Alkyd enamel;
- Oil enamel;
- Water based.
All types differ from each other in production technology, composition and characteristics.
Acrylic enamel
Acrylic paints:
- have no characteristic odor and are great for interior work.
- Their widespread use in everyday life is also due to the fact that they are quite dry quickly,
- differ increased moisture resistance,
- uniform application on any surface,
- and are also absolutely safe for people.
- Due to the fact that the substance contains special additives, a layer of paint does not begin to crack and turn yellow when the temperature of the radiator or battery increases.
- In addition, it should be noted that manufacturers offer huge range of colors Therefore, acrylic paint for heating radiators is often used in surface decoration.
As for the disadvantages, the most significant of them is high price. However, it fully corresponds to the good performance qualities of the paint.
Alkyd enamel
Alkyd paints, manufactured using the latest technologies, have the following advantages:
- A surface coated with a layer of such a substance is resistant to elevated temperatures - it does not crack when heated up to 1200С;
- High strength;
- Homogeneous structure layer upon application;
- good abrasion resistance when operating radiators and radiators;
- Wide range of colors allows you to choose almost any color;
- Layer maintains integrity for a long time.
However, in addition to the advantages, there is also a disadvantage - it remains intact for several days after painting. bad smell, which may subsequently appear upon sufficiently strong heating. In addition, some brands sometimes fade a little and may also change shade.
Water based enamel
Odorless, water-dispersion paint for hot radiators is an excellent option for coating radiators. It differs from other types in a number of features:
- It is made on the basis of ordinary water, so it is absolutely safe for people and environment;
- Special dispersed particles are not harmful;
- No unpleasant odor;
- For completely dry absolutely required some time;
- Easy to apply and a uniform layer;
- Thanks to the water-repellent effect, painted batteries can be washed without destroying the layer;
- Suitable for use in the most different rooms.
The disadvantage can be called not too varied color scheme, because basically she is only white.
Oil enamel
Oil products are in quite high demand due to a number of their advantages:
- No pungent or unpleasant odor after application and further heating of batteries and radiators;
- Are divided into colored and colorless;
- Easy to apply on metal surfaces;
- Form uniform layer;
- Great suitable for indoor use both residential and non-residential premises;
- Low cost compared to other types of battery paints;
- Can be used for decoration surfaces - applying patterns and complex designs.
The downside is that it takes a lot of time. This is due to the fact that a solvent is added to the paint.
Before painting batteries, their surfaces must be prepared. First, they are washed from dust and dirt and dried, and then sanded with fine sandpaper. Peeling old paint is removed before processing.
Advice. On chips of the old coating or in places where it was removed after painting, visible depressions will remain. To prevent this, it is better to clean them, fill them with metal putty and, after drying, sand them, leveling them with the rest of the surface.
Second stage - priming
This is especially important when applying acrylic enamel to bare metal or a layer of putty. The grade of primer is selected for metal; you cannot use a primer intended for wood or other materials as a base.
After priming, you need to allow the drying time indicated on the packaging.
The last stage is painting. Having covered part of the wall behind the radiator and the floors underneath with film, the coating is applied in 2 layers with a brush, roller or spray gun. The latter method is the most preferable, as it provides penetration into hard-to-reach places.
Advice. It’s better not to paint hot batteries; not all paint is designed for this. And the smell in this case will be stronger, so it is recommended to carry out the work in the off-season.
Choosing paint for pipes
The answer to the question: is it possible to paint hot pipes has already been provided, so let’s move on to choosing a dye. Today there are several types of paint that are a priori suitable for treating hot radiators.
- alkyd enamel - the surface treated with this material can be matte or glossy. The paint creates a durable coating. Among all the variety of these dyes, there is a special one for radiators, which can be applied to hot pipes. In addition, the enamel will create a barrier against rust formation;
- acrylic paint - has proven itself well at home, as it is easy to use and does not emit an odor when drying due to the fact that it is water-based;
- oil paint - this material is hopelessly outdated due to its characteristics (it takes a long time to dry, has a pungent odor) so we will not consider it;
- spray paint – suitable for use in industrial environments, requires special application skills. This material is not suitable for use in the home;
- silicone-based dye - due to the cost and specific application, such paint is significantly inferior to the first two options;
- a dye based on heat-resistant varnish - excellent for heated pipes, but in a city apartment and private house the radiator temperature is unlikely to rise above 90 degrees, so using such a dye is not advisable;
- water-dispersion paint - dries quickly on a heated surface, which interferes with high-quality film formation. Moreover, such a dye already has poor abrasion resistance - it is not suitable.
Of all these paints, the ones that have proven themselves best are: alkyd enamel and acrylic paint. But they have two drawbacks: alkyd enamel emits an odor, and acrylic enamel does not protect against rust. To avoid the unpleasant odor from alkyd paint, you can use acrylic paint, but before that you need to apply a layer of primer to the batteries. This paint for hot heating pipes holds up quite well and does not darken over time.
Examples of enamels for painting radiators
Among the range of special radiator paints, there are options that are better suited than others. For example, among alkyd enamels, the Swedish paint “Elementfard Alkyd” is superior in its characteristics to competitors (it emits very little odor, dries quickly, is used at surface temperatures up to 100 degrees, does not require priming). And also the Dutch paint “Radiator Paint” helps to positively answer the question: is it possible to paint pipes during the heating season? After all, its range of application up to 90 degrees is enough to paint hot pipes.
Do-it-yourself painting of heating devices
The workflow for painting batteries and pipes with heat-resistant compounds includes several stages:
- Preparation of the treated surface.
- Application of coloring composition.
To carry out the work you will need the following tools and materials:
- Brush with a metal base.
- Paint brushes – regular and radiator.
- Coarse sandpaper.
- Cleaning brush.
- Spatula with a metal tip.
- Primer for metal.
- Paint for batteries.
- Degreasing or solvent composition.
Preparing surfaces for painting
To perform high-quality painting of heating devices with your own hands, you need to properly prepare the surfaces. Preparatory work includes the following activities: cleaning of old coating, removal of corrosion, degreasing and priming.
- The surface is thoroughly cleaned: the old coating is removed, areas damaged by corrosion are sanded to a shine. Dirt is removed with a brush, and paint with a spatula or special chemicals.
- After removing the paint, the surface is sanded with a brush with metal bristles, a special attachment for a drill or a grinder. When working with surface cleaning, personal protective equipment is used.
- The cleaned surface is sanded with sandpaper and degreased with any available solution.
- A primer with anti-corrosion properties is applied to the prepared surface for maximum protection against corrosion and increased adhesion of the paint composition to the base.
Features of surface painting
Most modern compounds are applied to a cold surface, so the hot battery must be cooled before painting. To obtain a high-quality coating, it is recommended to paint batteries following a certain technology.
Liquid formulations
If the work uses an oil, water, water-based or other liquid composition, it is necessary to properly prepare the workplace and protect the surrounding surfaces with a clean rag.
- For painting, use a brush with a curved handle or a soft sponge. The coloring agent is poured into a wide container. Hands are protected with gloves.
- The composition is applied in a thin layer to the internal surfaces and in hard-to-reach places, then the outer part of the heating device is treated. Smooth strokes are made from top to bottom, which will allow you to evenly apply the enamel to the surface.
Important! If visual defects appear after painting, re-painting is necessary. .
Aerosol formulations
If odorless spray paint is used for painting, the principle of surface treatment is as follows:
- First, hard-to-reach places are processed, then the outer parts of the central and other heating elements.
- Smooth movements are performed in a zigzag manner from top to bottom.
- The surface is treated in two layers to obtain a uniform coating.
If enamel for radiators is applied using a spray gun, then the principle of surface treatment is similar to balloon painting.
Before painting heating radiators at home, you should carefully study the features of the technological process, because compliance with all stages will ensure high performance characteristics and a long service life of the devices.
Radiator paint thinner
Of course, the new paint will lie tightly and evenly only if the old coating from the radiators is completely removed. In order not to waste time scraping the metal by hand or stripping it with a drill and brush, you can use special gel removers. This composition is applied to the surface of the radiator and left for a certain time. When the paint softens, simply scrape it off with a spatula.
You can apply paint remover with an old brush with natural bristles or a metal or wooden spatula. Among the various wash options, there are aerosol types of wash. In order not to damage neighboring surfaces, before spraying the composition, cover all nearby objects with film.
Manufacturers indicate the exposure time for various compositions on the packaging. After a specified period, the old coating becomes soft enough that it can be removed without difficulty.
Although the remover contains chemically active components, they do not damage metal and wooden objects, as well as skin. But it is still better to use gloves when working. Residues from the radiator can be washed off with plain water.
Such brands of remover as B-52 or SP-6 performed well. Domestic and foreign manufacturers produce many analogues of such substances, varying in price and depth of penetration.
conclusions
As it became clear, the range of types and colors of dyes for radiators is very extensive. When purchasing, you will need to choose the color and type of paint - matte, semi-gloss or gloss
In addition, it is important to decide what kind of paint you want to buy - alkyd enamel or acrylic. The last step is to select a manufacturer.
Preparatory work and process of painting batteries
To understand how to paint a heating radiator, you need to know the principle of the work being performed.
Like all types of construction work, the painting process begins with the preparation of batteries. First of all, it is necessary to eliminate contaminated areas and check the product for corrosion areas.
Once the old paint and dirt have been removed, the heating radiator should be wiped with a damp cleaning cloth.
Swollen areas must be cleaned with sandpaper, and if rotten areas are found, they must be eliminated.
At the final stage, you should coat the radiator with a primer mixture, but you should only take into account the characteristics of the further material, because some types of paint and varnish products do not require a primer layer.
Several types of cleaning are used to clean heating devices from dirt and old paint. The first method is called chemical, and the second method (which involves using a special tool) is called mechanical.
To remove dirt chemically, solutions consisting of acids and solvents are used. You can prepare this mixture yourself or purchase it at the store.
To prepare the solution at home, you will need the following ingredients:
- sodium carbonate (soda ash), about one kilogram;
- slaked lime, in the same proportion;
- water, about five liters;
- large capacity, more than ten liters.
The solution is prepared as follows. Soda is dissolved in hot water, the water temperature is about 60 degrees, after which lime is added in small doses. This is done to prevent strong foam.
The mechanical method involves the use of a special tool or ordinary sandpaper.
The process is long and dusty, but to speed it up you can use a special drill attachment or use a grinder.
In this case, it is necessary to follow safety rules and carry out such work carefully so as not to damage the radiator.
As for the painting process itself, no special skills are needed, the main thing is to know how to paint a heating device correctly.
Before starting work, you should set up a workplace, cover the floor with paper (or other material), protect the walls with a gasket (you can put a large sheet of cardboard), prepare the necessary tools.
Apply paint to radiators with a brush, preferably from top to bottom - this way there will be no drips. The layer should be thin and uniform. After the paint has dried, you need to apply a second coat.
The internal parts of the radiators must be painted first to avoid getting dirty in the process. Small parts and difficult places should be painted using a sponge or roller.
That's the whole principle of painting radiators.
Coloring stages
To ensure that the result does not disappoint and money is not thrown away, it is better to paint the radiator in accordance with a certain technology:
1. Prepare the workplace: cover the floor and cover the wall. Select tools for painting. Only brushes are suitable, sometimes sponges are used. A roller is definitely not suitable for this type of work. The employee must cover his hands with gloves.
2. You should take a little paint onto the brush so that it does not flow over your hands and the handle of the painting device. This way, you can avoid drips on the battery elements and drops on the floor or wall, and the enamel will lie in a more even layer.
3. First, the inside of the battery is painted. To make the procedure as high quality as possible, a sponge is often used. Light wetting movements cover the surface.
4. The outer part of the heating element is painted second. This is done using a brush of medium thickness. Strokes are made in one direction from left to right or vice versa. It is advisable not to change the direction during the process.
It is better not to apply the paint in a layer that is too thick - it should be thin and more or less uniform. If after drying any defects are visible, then re-painting should be done on the already painted elements. The principle of operation consists of the same steps as applying the first layer of paint.

Reasons for failure
A common reason for unsatisfactory painting results is failure to comply with the enamel drying conditions. It is risky to carry out work during the heating season, when the batteries can turn on and heat up. This common mistake usually ends in an unsightly result. High temperatures cause drying too quickly, weakening the resulting coating. Radiators can be painted at room temperature. Paints are resistant to temperatures up to 100 degrees Celsius, however this does not mean that they can be applied at such temperatures.
Conclusion
Hiding old radiators behind heavy curtains or furniture is not a good idea. By hiding radiators behind curtains, we restrict the flow of heat, reducing heating efficiency. Old, cast iron, steel batteries can be quite effective, they are durable and reliable, so replacement is not always advisable. However, it is difficult to consider them as a decorative element of the interior. Modern means can correct an aesthetic defect - old radiators can be painted
In order to get a beautiful, durable end result, it is important to properly prepare the surface, choose the right way to paint the batteries, choosing a paint with good resistance to high temperatures.
Features of paint application
Before painting, the heating radiator must be cooled. This is because most paints are designed to be applied to a cold surface. If they are applied to hot metal, they will dry quickly. And this will not allow you to apply an even layer and correct smudges, stains and stains in a timely manner. In any case, provided that you work on hot batteries. There is very little time to apply paint. In this case, the mistake made may remain uncorrected. This is often noted in various videos.
True, there are some exceptions
So, people who ask the question whether it is possible to paint hot batteries should pay attention to paints specially designed for this purpose. They are able to dry on heated metal very slowly
However, such paints are quite expensive, and the final result of calculating a small repair will be a considerable amount. Therefore, before painting the heating radiator in winter, it is better to turn it off and wait for it to cool. It is best to change the color of the heating device in the summer season. Then it is convenient to ventilate the room and the radiators are cold.
If you have to paint a cast iron heater with ordinary paints during the heating season, then you need to apply a very thin layer of paint. Apply two such layers.
The application of a color mixture of a certain color occurs in the following sequence:
- Place oilcloth or old pieces of newspaper under the radiator.
- Applying paint to the top of the product. Then they gradually go down. Thanks to this, the problem of smudges is eliminated. First, the color mixture is applied to the internal parts of the device, and then to the external parts. The entire surface needs to be painted.
- Drying of the first layer of paint.
- Apply the second layer in the same way as the first.
The battery is coated with paint using various tools, namely:
If you plan to use a brush, then you should take several options. The first should have soft, straight bristles. The other has curved stubble. Thanks to the second, you can work with your own hands in those places to which access is limited.
If painting with a spray gun, it is better to remove the battery. This way, excess paint will not get on the walls. In addition, there is a great opportunity to paint the most inaccessible places.
Spray painting is very quick. In this case, you need to perform zigzag movements. They move from top to bottom. The distance from the surface to be treated to the can should be 30 cm.
Powder dyes
With the help of such dyes, steel, bimetallic and aluminum batteries are painted under production conditions. For home painting, it is used very rarely due to the need for a special tool - a spray gun. Although some services rent out such equipment.
According to the technology, a negative charge is transferred to the cleaned part, and a positive charge to the powder paint. To do this, you need a diesel generator that produces current at a voltage of 25-30 kV with a power of a fraction of an ampere.
The potential difference allows the powder to be evenly sprayed over the entire surface to be painted. The next step is to polymerize the dye so that it becomes rigid. It is performed by heating the product to a certain temperature. Its range is from 170-200℃ to 350℃.
The lower temperature threshold can be created with a heat gun, but to pump up high temperatures you will need a furnace that will gradually warm up the product. Alternatively, you can use paint that polymerizes under the influence of ultraviolet radiation. Then in a closed room it is enough to turn on a special lamp for a specified time.
Be that as it may, such technology is difficult to implement at home. You may be able to have your radiator painted in an equipped auto repair shop.
Thus, from all the options for paints for radiators, everyone can choose the most suitable and most affordable one. Even if it is oil paint, this is not a relevant choice, but it has a right to exist.
Features of paint application
Applying one or another type of paint to radiators is not quite a simple job, as a person who is far from understanding the technology of painting work might think. After all, the reliability of the coating and its durability will depend on how correctly all the stages of painting were followed.
Preparatory stage
Painting with acrylic paint
Preparing radiators for painting is the most important and first stage, on which the final result largely depends. First, you need to thoroughly wash the heating device, using for this purpose a special spray bottle with washing liquid, a soft cloth and a brush. Even new batteries require preliminary preparation, since even the highest quality paints without their characteristic odor should lie smoothly and evenly on the surface. Next, you need to degrease the devices and also clean them with sandpaper to remove various irregularities on their surfaces and better adhesion to the paint.
Before applying the coloring composition, you should remove the old coating layer, and also treat areas susceptible to corrosion with special compounds.
Preparation of tools and materials
Before removing the old layer of paint and applying a new coating, you need to make sure you have the necessary tools and abrasives on hand:
- Tassels.
- Drill brush attachments.
- Sandpaper used to remove old paint.
- Degreasing composition.
- Primers with components to protect metal from corrosion.
- Abrasive - for removing thick layers of old coating.
Features of applying paint to radiators
Acrylic enamel for radiators
In order for the final result to be what you expect, you should not only choose the right paint, carry out all the preparatory work carefully, but also apply a new composition according to the rules:
- All restoration and painting work should be carried out during a heating shutdown to avoid streaks and unsightly stains.
- It is important to apply paint from top to bottom so that any random drips that may appear do not spoil the already treated surface. The batteries must be completely covered, including the back and inside of them. In order to paint hard-to-reach places, there are special battery brushes that have a curved shape. It is most effective to treat the device in two thin layers to avoid unevenness. But in this case it is necessary to wait until the first applied layer is completely dry. And only after this can the next layer of paint be applied.
- The aesthetics of the battery will depend on how carefully the paint, oil or any other, is used. For convenience, spray cans, special rollers and brushes are often used. It is recommended to start the process from the most inaccessible places, applying the composition evenly.
- If the technical parameters of the radiator allow it to be removed from its hinges and completely covered with paint, then this will be the best option.
When carrying out painting work in the summer, it is necessary to keep the windows open to protect yourself from the negative effects of coloring compounds. In addition, you need to use respirators and gloves so that after finishing work on painting batteries, you do not damage the skin of your hands with various solvents when scrubbing off paint stains.
Requirements for enamel
The main thing in choosing paint for a home heating radiator is its heat resistance. If the labeling of the can indicates that the composition has an operating temperature below +800C, then you should not use such paintwork for painting the battery. Such paints and varnishes are not initially intended for painting heated elements of the heating system. After turning on the heating, they will begin to peel off or turn yellow.
The best paint for batteries is one whose label says “designed for heating radiators” and “quick-drying”
The paint for painting the heating device yourself must be at the same time:
- heat-resistant (minimum +800С, and preferably +1000С);
- moisture-resistant and abrasion-resistant;
- non-toxic;
- with high thermal conductivity;
- quick-drying.
Due to inexperience, some choose ordinary non-heat-resistant paint for interiors for batteries. As a result, when heat is applied, it turns yellow or changes its original shade. This is due to the presence of chalk or polymers in its composition, which are not designed for high temperatures. Therefore, both the binder material and the pigment must be heat resistant.
The paint on the battery is usually applied in two layers. The faster each of them dries, the faster the radiator will be ready for use. Moreover, often the faster the paintwork dries, the more pungent the odor of the composition. So that the family is not forced to inhale these ambers, it is often easier to remove the heating device from the pipes and paint it somewhere in the garage or on the street.
Inexpensive chalk is often added to paint as a filler to reduce its cost; it is better to discard such paint and varnish immediately - such enamel will definitely turn yellow
When choosing between a glossy and matte option, you should remember that the slightest irregularities are noticeable on a shiny surface. For rough and lumpy cast iron batteries, it is better to choose a paint with a dull shade that will not produce glare from lighting.
Radiator cast iron often has metal streaks and chips. When using glossy enamel, all of them will definitely be visible. At the same time, you should not be overly zealous in leveling the cast-iron surface of the battery with sandpaper before painting. This can lead to thinning of the radiator fin and the subsequent appearance of a fistula.
Types of paints
The following types of coatings are mainly used for painting heating radiators:
- Enamel - the composition has an affordable price, as well as a wide range of shades. The disadvantages of the composition are its intolerance to high temperatures and reduced heat transfer from the battery. It is also worth mentioning the long time required for the paint to dry completely and the unpleasant, persistent odor.
- Acrylic dye is odorless, which is a big advantage of the product. In addition, it dries quickly and can even be applied to a hot radiator. Considering that the coefficient of adhesion of the dye to the surface is minimal, after a short period of time it begins to crumble and after drying it can change the primary shade - these are its negative aspects.
- Alkyd paint is a high-quality composition that is characterized by high heat resistance, the disadvantage is an unpleasant odor and prolonged drying of the treated surface.
- Special paint for radiators that withstands increased temperatures, so even hot heating elements can be treated with a similar composition. In addition, the composition dries quickly, does not reduce the heat transfer of the batteries and does not lose its original shade over time. The downside is the fairly high cost of this product. Such paints, which are odorless, will be the best choice for a living space.
Surface cleaning
We looked at how to paint a radiator depending on its type. Now let’s figure out how to clean a heating device from old, cracked paint.
There are two ways to clean the surface: chemical and mechanical.
Let's look at them separately.
Chemical method
In this case, special products consisting of fatty acids and solvents are used. They soften the layers and weaken the adhesion of the paint and the radiator surface.
During this work, you should follow safety precautions and use protective equipment (respirator, gloves and goggles), since these substances are flammable and toxic. It is also necessary to periodically ventilate the room.
Let's consider the technology of work:
- Prepare a solution that requires soda ash - 1 kg, slaked lime, water - 4.5 liters.
- Soda is dissolved in water and heated to 60°C, while slaked lime is added in small portions. Since the solution foams, a large container (10 l) is required. This mixture is suitable for any surface, but if it is difficult to make a solvent yourself, then purchase a special gel or liquid;
- The prepared or purchased solvent is applied to the surface with a brush;
- When the paint begins to foam and bubble, it is removed with a scraper or spatula;
- After removing all the paint, the surface is washed with water;
- If a gel-like liquid is used, then using a brush, smear it with a thick layer, leave for as long as indicated in the instructions and remove (with the old paint) with a spatula;
- In raised areas, use a wire scraper to remove paint.
Mechanical method
This is done using sandpaper. The work is labor-intensive, as it is necessary to clean the front surface of the cast-iron battery
To make work easier, use an electric drill on a sanding attachment, which is used to secure sandpaper, but be careful not to make a hole in the heating device, otherwise it will have to be replaced with a new one.
Brushes and scrapers are also used for mechanical removal of paint from the surface.
These methods allow you to understand how to remove paint from a battery yourself. And if it is necessary to remove rust, then a corrosion inhibitor is used.
How to paint a battery
It is advisable to plan painting of heating radiators for the summer. It is preferable to carry out the work before the start of the heating season, otherwise you will need to temporarily turn off the heating system and wait until the battery cools down to room temperature. The radiator should not be too cold; the optimal temperature is in the range from +10 to + 30 °C.
- The floor and surrounding objects should be covered and protected from splashes - ordinary newspapers are ideal.
- Mix the paint thoroughly before starting work.
- We cover the heating radiator with 2-3 layers of enamel, maintaining the required time interval each time (usually 4 hours).
- Radiators can be coated with paint using a special flat soft brush, roller or sprayer.
Typically, flat brushes with a long handle are used. It is worth buying a special brush for painting batteries, which has a width of 26-63 millimeters.
When applying paint with a roller or brush, you need to ensure that the brushes do not lose bristles when painting.
It is important to avoid drips and uneven coverage. Radiators can be turned on after coating after approximately 24 hours
The exception is quick-drying varnishes.
Types of paints
What paint should I use for radiators? You are very lucky if you have modern radiators with powder coating at your disposal - it lasts for decades without peeling and almost without changing its color. This paint covers aluminum, bimetallic and steel radiators of various designs. To give it extra strength, the paint is subjected to procedures to make it stronger and more durable. Multi-stage painting has the longest service life.
Painting the batteries is necessary not only to give the radiator a neat appearance, but also to protect it from the environment.
If there are ordinary cast iron accordion batteries or old steel batteries in the house, then they need to be periodically tinted. The paint quickly turns yellow and begins to crumble, exposing the metal and creating all the conditions for the formation of corrosion centers. Therefore, the paintwork needs to be updated. It may also be needed when carrying out repairs - what if you decide to paint the batteries in different colors and adapt them to your interior design?
What paint should I use to paint radiators? There are many types of paints:
- water-dispersed – do not emit an unpleasant odor and dry quickly;
- acrylic – they smell like solvents and give a gloss;
- alkyd – resistant, durable, long drying;
- oil paints are not the best option for painting batteries;
- Heat-resistant silver is an excellent option for painting heating appliances;
- silicone-aluminum - excellent in all respects, but very expensive;
- car enamels from spray cans are a reasonable heat-resistant option.
The water-dispersion composition for radiators is completely safe, as it dissolves in water.
Water-based paints are good because they do not have a strong solvent smell, since their base is ordinary water. They are fast drying and good for painting radiators. Some varieties have marks indicating the possibility of painting heating devices.
Don't like matte radiators and want them to shine? Then we recommend that you turn your attention to modern acrylic enamels. They give excellent gloss and have a long service life
Their disadvantage is the smell of solvent, so the premises will need to be ventilated after painting.
Alkyd paints are the most durable. They are resistant to temperature loads, resist abrasion well, and do not change their color for a long time. Some of them can withstand heating up to +150 degrees without turning yellow for many years. Despite the obvious advantages, such paints have one glaring drawback - a strong solvent smell. It manifests itself not only at the painting stage, but also when starting the heating system .
Some consumers note that after drying, the unpleasant odor disappears, but appears already when heating is started for the first time, disappearing after 1-2 days. During these periods, it is recommended to thoroughly ventilate the rooms in which painted batteries are located.
Oil paints are not very suitable for heating radiators, so they have hardly been used recently. They have a strong solvent smell, take a very long time to dry and stick, and the dyes used in them turn yellow over time. In addition, after a year or two, such painting will begin to peel off and fall off, exposing the metal of the heating devices. We do not recommend using this paint for painting heating radiators.
Radiators painted silver look very attractive, but the main thing here is that the surface of the battery is smooth, without bumps or depressions, otherwise the impression will be blurred.
Heat-resistant silver is an excellent choice for painting batteries silver.. It contains heat-resistant varnish and powdered aluminum. Benefits of silver:
- withstands heating up to +200 degrees;
- does not change color;
- It hardly peels off or falls off.
The disadvantage is that the smell is quite strong, so after painting the batteries, the rooms need to be ventilated.
Silicone-aluminum paints have the greatest resistance to high temperatures. They fit well on any surface, forming a strong and reliable connection. The surface is smooth and flexible, the paint does not peel off even after several years of use. The price for such superior performance comes at a price - you have to pay for the benefits and durability.
Car enamels are also suitable for painting heating radiators. They are resistant to temperatures up to +80-100 degrees and form a shiny, glossy surface that does not change color under the influence of temperature loads.
Conclusion
Home craftsmen often wonder whether it is possible to paint hot batteries with acrylic paint. It has almost no smell, and is also the most popular due to its affordable price. The base enamel is a product with a snow-white structure. In order to change the shade, a tinting pigment is added to the ingredients. Such coatings have a slightly lower temperature threshold compared to alkyd coatings and amount to 80 °C. However, in practice it turns out that this is quite sufficient.

It is very difficult to find a person who has never held a brush in his hands. Therefore, many people do not think about how to paint a battery, believing that there is nothing special in this process. In fact, without some attention, the radiator will become the same as before the repair: rusty, with peeling and swollen paint. This is why many are forced to update the appearance of heating elements almost every year, instead of learning how to paint the battery correctly. But then you can return to this task no more often than once every five years or even ten.
