Connecting the corners of the ceiling with plinths. How to properly cut ceiling plinths - internal and external corners, fitting uneven ones, joining rounded corners. Using decorative corners

The quality of the ceiling finish greatly influences appearance premises. That’s why they try to do everything perfectly, or very close to it. The finishing touch to the design is ceiling plinth. They give the finish a finished and holistic look. The planks themselves smooth surfaces They are easy to install: using a special white glue, but problems arise with the design of the corners. Without knowing how to make the corner of a ceiling plinth correctly, a lot of material is spoiled. We’ll tell you how and with what to cut it in the corners.

What is it made of and what is it called?

The very first plinths on the ceiling were made of plaster. They were cast in special molds, then installed on the ceiling using mortar. Such figured decorations were called fillets. Today you can rarely see them: they are expensive, but in appearance they are almost no different from cheaper options. And this name is almost lost.

The most popular ceiling plinths today are made of polyurethane or polystyrene. They are inexpensive, look great, are easy to install, and have a wide range of profiles and patterns. The width can be from 5 mm to 250 mm. They are used in almost any room, decorated in any style. Exception - Wooden products are most often used here - style dictates its own conditions.

There is also a similar plastic finish. It is mainly installed in bathrooms. But also in wet areas You can safely install polyurethane strips - they are not afraid of dampness.

You need to cut ceiling plinths in corners from any material using one of the methods described below. The only exception is plastic skirting boards: such a corner can only be created using ready-made corners.

What and how to cut

Working with skirting boards from different materials implies the use different instruments for cutting. When working with wooden ceiling plinths, it is more convenient to use a wood saw. All others, including plastic, foam and other polymers, are better cut with a metal blade. This results in a smoother cut and less burr. Saws are usually used when working with a miter box.

When working with foam baseboards without special devices cut them with a good stationery knife. Its blade is quite thin and even, the cut is smooth and not wrinkled. If you work with polyurethane or polystyrene with a saw, do not press hard: you can dent it.

In general, to get a little used to the tool and material, take a piece and practice on it: cutting, sawing, trimming. This way there will be fewer problems during work.

How to get the right angle

The most problems when working with ceiling skirting boards arise when decorating the corners. Since the surface of the products is complex, simply cutting at the desired angle will not work: it is also necessary to trim so that they fit together and, preferably, without large cracks. In fact, there are several ways to make the corner of the ceiling plinth ideal (or almost).

Using a miter box

If the corners and walls in the room are smooth, you can use a special carpentry tool- miter box. This is a gutter in the shape of an inverted letter “P”, in which lines are marked for cutting at an angle of 90° and 45°. The part to be cut is placed inside, and a saw is inserted into the guides. The part is held in place and cut at the required angle.

In the case of baseboards, not everything is so simple: they must simultaneously adhere to two surfaces, so they need to be pressed against one or the other wall of the miter box. When working with ceiling ones, they are pressed against the side closest to you.

The sequence of actions when finishing the outer corner is to make a cut at an angle of 45 degrees. Place the miter box in front of you. You try on how the plinth will be positioned, determining which part of it will be attached to the ceiling. In order not to get confused and to cut the ceiling plinth correctly, place the plank that will be located on the right on the right, and the one on the left on the left.

Press the part that ends up on the ceiling to the bottom of the miter box. The second side is closer to you and raised. You rest it on the wall of the device so that it does not wobble when cutting. That is, the front part of the plinth turns away from you. Make the cutting direction as shown in the photo below. By putting the two cut pieces together, you get a protruding corner - an outer or outer corner.

How to make an outer corner of a ceiling plinth using a chair

First place the sawn parts in place “dry”, without applying glue. If the geometry of the corner turns out to be not so ideal, you can correct it a little with a knife. It is easier to cover up small errors with special putty.

The situation with the inner corner of the ceiling plinth is very similar. First, try on which side will be on the ceiling, press this part to the bottom of the miter box, rest the second part on the wall closest to you and make cuts as shown in the photo below.

And again, first try it on without applying glue, and if necessary, adjust it slightly. Then apply a thin bead of glue to both surfaces that will be attached to the wall or ceiling.

Your version of how to use a miter box correctly is shown in the video.

How to make a corner of a ceiling plinth without a miter box

Few apartments or houses have angles exactly 90°. Small deviations can be easily corrected after trying on. But not always. Then you have to mark everything “in place” - under the ceiling.

You will need a finely outlined pencil (hard - it is not so visible on the ceiling, but leaves fairly clear marks close up), a small piece of plinth, a ruler and a good stationery knife if you are working with polyurethane (polystyrene) baguettes or a metal saw for working with other materials.

Place the plinth against the corner and draw along the outer edge with a pencil. Apply to the other side of the corner and also mark. You have a cross on the ceiling, the center of which marks the place where the ceiling plinth strips should meet (look at the photo). Having placed a piece of plinth in the corner that will be glued there and resting its end against the wall, transfer the mark to it.

How to make corners on ceiling plinths without using special tools

Now take a ruler and connect the edge of the baseboard with the marked mark. If you just put the plinth on the table and cut it along the line, the two parts in the corner still won’t fit together: it will get in the way inner part. It can be trimmed later by trying it on the ceiling. The second way is to install the piece that needs to be cut on the table with the part that will be on the ceiling. And cut along the line, but holding the knife at an angle of about 45°. You will still need to make adjustments, but much less (and less likely to make mistakes).

Repeat the same operation with the second bar. Place it against the desired wall, rest the end against the adjacent wall, mark the place where the cross is drawn, draw a line and then cut it off. Adjustment is carried out “dry” without applying glue.

You repeat exactly the same steps for the outer (protruding) corner. Now you know another way to make a corner of a ceiling plinth, without a chisel or other special devices.

Using decorative corners

There is another, easiest way. For skirting boards made of polyurethane or polystyrene, use ready-made, factory-made decorative corners. They are installed in a corner, and the strips are glued tightly to them. Trimming them if necessary is very simple: a few millimeters with an ordinary stationery knife.

How to join in corners

If the installation of the first corner is completed, you can assume that you have already learned how to do almost everything. “Almost”, because you still need to learn how to connect the corners and cut the planks to length. When some part has already been glued and there is a small distance left to the corner, how can you not make a mistake with the length? The answer is simple: leave a reserve.

At first, you can cut a piece 10-15 cm longer: you will have the opportunity to redo it several times if something doesn’t work out right away. Then you make an angle in the manner described above, try it on dry, adjust everything so that the result suits you. Only after this can you place the already cut strip in the corner and mark the place to which it can be shortened. You need to cut exactly 90°. It is not necessary to use a miter box. Just try to place the knife (hacksaw) perpendicular to the surface.

The plinth is the finishing touch of the entire renovation. This applies equally to the ceiling and floor. After this element, only a plastic corner can be installed in the arched and window opening. But still, let's talk about baseboards.

Based on the fact that the principles of working with these elements are the same on both the ceiling and the floor, we will not focus on the location, but will focus on the techniques and everything that accompanies them, the choice of tools, and methods of fixation.

What and where you can work

Currently, the most purchased products for work are:

Wooden skirting boards. These are, as a rule, solid wooden products with a relief outer surface. In some cases, grooves are prepared in such skirting boards to hide wires.
Fixing the skirting boards to the wall occurs with self-tapping screws into dowels; fixation is allowed in other ways, for example, with sealants, but this technique has not proven itself well; there is nothing more reliable than self-tapping screws;
Plastic products. By and large, this is not only the simplest, but also the most thoughtful designer. In this case, everything has been thought out: there are designs for external and internal corners, right and left side caps, there are even special fasteners for them that are fixed to the wall, and the plinth is simply inserted into them.
In addition, the baseboard itself is hollow and can perfectly hide wiring and communication cables. Working with them is simple and will be discussed immediately in the next section;

Foam and- this is already ceiling structures who do not like rough fixation and prefer glue or liquid nails.

More about plastic

What, what, eh plastic products They don’t need any introduction; it’s hard to imagine designs that are lighter and more varied in color. Plastic floor skirting boards are most often selected in a single color scheme with floors.

At the same time, it absolutely does not matter what kind of covering you have on the floor: laminate, linoleum or simply painted fiberboard, there is a skirting board of a suitable color for all of them. And working with him is a pleasure.

In this case, you need to do the following:

Using a tape measure, determine the dimensions of the perimeter of the room or several rooms in which you are going to install this plinth. Calculate the number of internal and external corners, since these are where ready-made corner elements, as well as the number of connecting elements;
After purchasing, cut the material and cut the plinth itself, not forgetting to make adjustments for the size of the joint groove in the finished corners. The products themselves are perfectly sawn with a saw with fine teeth on the miter box using ordinary cross cuts; if small plastic shavings appear, they can be removed with a mounting knife;
The finished fragments are fixed either with self-tapping screws to the wall, or with clips, which are initially marked and fixed to the wall with the same self-tapping screws;

Note!
Joining skirting boards in the corners does not require additional fixation, however, if you have animals or small children in the house, then in order to be sure of their safety, the integrity of the structure, as well as the normal aesthetic appearance of the entire ensemble, it is still better to join In the outer corners, secure with glue for ceiling or floor plinths.

Docking with already exposed elements. These are, as a rule, door frames, which can be made of wood and with completely different parameters, both width and pattern. There's nothing wrong with that.
The junction of the door casing and the plinth is made as follows: a plinth is brought to the already installed casing in such a way that there is the minimum possible distance between the casing and the product with a side plug, preferably end-to-end.

Working with internal corners, right and wrong

If you work with wood on the floor or ceiling, then you cannot escape the issues of joining. Here you will have to join and join with minimal gaps, and for this you will have to work hard.

So, we consider all the work options:

Option one: right angles. 90 degrees is a builder’s and repairman’s dream.
In this case everything is simple:

The product is placed in a miter box in such a way that the floor part of the product is placed on the base, and the side part (which will be fixed to the wall) on the side of the device;
On the side scale we find a groove with a mark of 45 degrees in the direction we need and begin cutting with a hacksaw with small teeth;
If necessary, the cut and the front part of the plinth can be lightly sanded with sandpaper;

Advice!
How to dock wooden baseboard?
This question will definitely arise, since even with a very precise fit, a gap will remain.
In this case, you will need a special wood putty.
It is easy to apply, and after drying it is easy to remove the excess with sandpaper, especially since the wooden plinth will still either be covered with stain and varnish, or painted.

Not right angles - option two. Unfortunately, not always, far from always, you will find right angles, especially in houses that have already exceeded a certain age. Therefore, in this case, the question of how to join the plinth in the corners will come first.

In this case we do the following:

A lot depends on correct measurement. The plinth is brought to the corners on both sides, and the outer floor border is outlined with a pencil or other marker, which can then be easily removed. As a result, you will get a rhombus, the diagonal of which drawn from the corner outward will be the cutting line;
Transfer the cutting line to the material and also perform the necessary manipulation with a hacksaw;

Interesting to know!
Some craftsmen advise making the cut slightly indented in the direction of increase, so that it is possible to adjust the joint manually.
We can advise you - try it.
Experiments are always useful, especially since the risk is minimal, if you succeed, very good, no, there is always putty for small defects.

The junction of the plinth and the platband is carried out in the same way as described earlier;
Working with ceiling skirting boards follows the same rules as with floor skirting boards.

External corners and working with them

Since the outer angle is 90 degrees, how to join the skirting boards is clear without words, especially since the process has already been described. Just remember to choose the correct direction of the cut as you work. But what to do with angles that are no longer 90 degrees, but have floated slightly? Let's talk about them.

Instructions for working with such angles are as follows:

Place a plinth against one of the walls and move it slightly beyond the corner, mark the outer and inner boundaries;
Carry out similar manipulations with the second plinth;
As a result, you will get the same rhombus at the intersection points and the diagonal from the corner of the wall outward will be the cutting line;
You can also carry out similar “ritual movements” on the ceiling, or you can lay the plinth on the plinth and use two points: external and internal to determine the direction of the cut;

Finally

All installation work is not complicated and allows you to quickly put the products in place with your own hands; the cost of installation is the price of materials. The video in this article has prepared its own report on the topic." width="640" height="360" frameborder="0" allowfullscreen="allowfullscreen">

You already know how to seal cracks; in ceiling plinths, instead of putty, sealant or “liquid nails” are used. The joining of the plinth and the platband, if planned, is carried out according to the same principles.

Finally

Ceiling skirting boards are decorative elements that are installed in those areas where the walls connect to the ceiling. Installation of skirting boards is a specific operation that requires a competent approach, and the greatest attention should be paid to joining the corner parts. Before installation, the plinth is always cut into pieces of the required length. The edges of the products are carefully trimmed at a certain angle so that they can be joined normally. This article will discuss how to join ceiling plinths.

Features of ceiling skirting boards

Ceiling skirting boards perform not a practical, but a decorative function, which is to mask the gaps between the walls and the ceiling. However, in the case of stretch ceilings this function is a necessity - the distance between the canvas and the walls is initially quite large, so it has to be hidden somehow.

In addition to their masking capabilities, skirting boards can also be used for decorative lighting. This idea is very simple to implement, and the effect is extremely pleasant. Small ones are installed under the baguette led light bulbs, which create soft light around the entire perimeter of the room or in a certain area, illuminating the stretched fabric. Of course, to install such a structure you need to know how to properly join the ceiling plinth.

Most often, polyurethane or polystyrene products are used for ceilings, but elements made of gypsum or natural wood can also be found on sale. Conventional skirting boards are produced in two-meter lengths, but various deviations from this standard are also possible. The surface of such products can be either smooth or with a certain volumetric texture. The color of the baseboard is usually matched to a specific interior - and the most popular option is White color, which often coincides with the tone tension fabric and light walls.

Important positive quality skirting boards are able to be combined with most materials used for finishing. Skirting boards look great together with, for example, plastic panels, or with wallpaper. You can also combine elaborate-looking ceiling plinths with stucco elements - this will complement the visual style of the room.

The need to install skirting boards

Installing ceiling plinths is not the last stage of arranging a room. Typically, skirting boards are installed before the ceiling is finished and wallpaper is hung on the walls. However, maintaining the installation sequence is not a problem - it is very easy to figure out. It is much more difficult to understand how to join the ceiling plinth, and to understand the technology for connecting individual moldings.

You can find products on sale different lengths and width. The width is selected individually, depending on the dimensions of the room itself and the finishing features. To determine the length of the skirting boards, you need to measure the room - but you need to understand that during the installation process the ceiling skirting boards will still be adjusted, so you can buy the longest products possible. The material of manufacture does not affect the choice at all.

When choosing, you can also use reverse principle. In this case, you need to buy parts whose corners are already prepared for joining. You won’t have to cut the corners of such fillets yourself - you will need to cut the straight parts of the skirting boards, and the cut, accordingly, will be straight. Joining the ceiling plinth in the corners in this case will be easier, but they will also be more expensive.

Before joining the ceiling plinth in the corners, and even before installing it, you need to thoroughly prepare the surfaces to which the product will be attached. The surface must be dried, brought to a smooth state and cleaned of various contaminants. In addition, if necessary, it is necessary to carry out work on leveling, puttying and priming the surface. When installing a plinth over plaster, it is recommended to pre-treat the product with water-based paint.

Even if the corners of the room itself are not very even, the skirting boards can still be installed correctly - all you need to do is follow the technology for this operation. Skirting boards should be laid from the corners located from the entrance to the room. To trim parts yourself, you need to use a miter box - a specialized tool that allows you to cut skirting boards at a certain angle (plinths most often have to be cut at an angle of 45 degrees).

Cutting ceiling plinths

To trim skirting boards before installation, you need to prepare the following tools:

A stationery knife or a hacksaw for metal (the choice depends on the material of the baseboard);
Miter box;
Square;
Ruler;
Pencil;
Construction knife (optional if it is necessary to cut the baseboard at non-standard angles).

To successfully cut parts, you need, in addition to carefully performing all necessary operations, also take into account various nuances. For example, with regular cutting of planks, you need to cut not only the inner, but also outer edge details. If you need to arrange an external corner, then the parts, accordingly, also need to be cut inside.

For cutting it is best to take good tools, capable of providing high quality and cutting accuracy. Of course, you can use a regular saw, but such tools are not very suitable for fine work. When using low-quality tools, there is always a risk of damaging the material during the cutting process, so it is better not to skimp on installation.

The best tool for cutting is an electric jigsaw - it provides high precision work and the greatest efficiency. In addition, it is very easy to work with such a tool, since it makes it possible to accurately set the direction of the cuts and make them as neat as possible.

The miter box, despite its versatility, may not be suitable in a number of situations. In addition, this tool is used extremely rarely in everyday life, and it is difficult to use it for its intended purpose - not every apartment has straight corners. In such situations, only a template made of cardboard or paper that completely follows the shape of the corner will help.

To simplify the process of cutting hollow baseboards, you will need to make a corner from scrap materials. You can put the cut plinth in such a corner, and it will be fixed. There are no special requirements for the quality of the corner - the main thing is that it securely holds the product throughout the entire work.

The corner is applied to the prepared template from above so that the edge of the corner coincides with the corner of the template. The plinth is inserted into the corner and cut according to the template. The advantage of this method is the fact that the blade of the tool can only rest against the corner itself, so there are no restrictions on the work.

For cutting foam parts, a regular construction knife will do. The only nuance that requires attention in this case is the sharpness of the blade. If the knife is poorly sharpened, then there may be delaminations and breaks in the cut, which are unacceptable when it comes to high-quality joining of skirting boards.

Technology for joining skirting boards

There are only two types of corners that require joining:

Internal angles that occur most often are less than 180 degrees (most often 90);
External angles, more rare - angles over 180 degrees (usually 270).

There are also sometimes non-standard configurations, but they can still be considered as a certain variety of external and internal angles. Regardless of the size of the angle, the joint always consists of a right and left strip, which need to be connected. The main differences lie in the method of trimming skirting boards for different meanings corner, so it is worth understanding these differences before connecting the baseboard in the corner.

How to join internal corners

In the vast majority of cases, it is the internal corners that have to be cut - i.e. corners of the room. The part of the plinth, which during the cutting process is adjacent to the sides of the miter box, will subsequently be glued directly to the wall. The other part, located at the bottom of the miter box, is connected to the surface of the ceiling. When arranging internal corners, the bottom of the plinth should be higher than its upper part, in contrast to external corners - in this case, everything will look diametrically opposite.

Before adjusting the corners of the ceiling plinths, you need to accurately measure the angle between the walls of the room. For right angles, planks cut at an angle of 45 degrees are used. If the corners in the room itself are uneven, then the radius of the corner should be divided in half. During the cutting process, you need to ensure that the parts eventually fit together - the left plinth is cut with right side, and the right one, respectively, with the left one.

In the case of cutting for internal corners, the technology will look like this:

Fitting the ceiling plinths in the corners begins by inserting them into the miter box and pressing the part a little further than the slot marking the 45-degree angle;
The plinth is cut according to the side where it should be located;
Before connecting the plinth to the ceiling, you need to attach it to its place to check whether it is suitable for installation in a certain area (small deviations can be carefully cleaned up with a construction knife).

External corners

You have to deal with external corners much less often, but you still need to know about them so that if you need to work in such conditions, you don’t get lost in how to properly connect the ceiling plinth in the corners. Cutting external corners is carried out using the reverse technology to the previous option: first of all, you need to find the starting point of the corner, then mark the product in the place where it will be cut, and after that you can start cutting the plinth directly.

Before marking, the plinth must be completely prepared for installation or direct joining. The prepared product is placed in a miter box and pressed. If the long part of the plinth protrudes from the left, then you need to cut it according to the left 45 degree designation. On the right side the situation is completely repeated. Before joining the plinth in the corners, the parts need to be checked on site and modified if necessary.

Non-standard angles

Meet angles of non-standard values in modern construction quite difficult - they are practically not equipped. However, such angles also occur - for example, in individual design projects there may be round areas. Connection between ceiling and walls similar cases you still need to mask it, so you have to figure out how to join the ceiling plinth in corners with a non-standard bend.

Usually the problem is solved by cutting the baseboard into several small pieces, the size of which directly depends on the bend of the corner. It is these pieces that will be used to connect the ceiling plinths in the curved corners. Having removed the excess putty after installation, you can begin installing the straight parts of the skirting boards.

Joining straight sections of skirting boards

When all the questions about how to connect the ceiling plinth in the corners have been considered, all that remains is to understand the technology for connecting straight sections of decorative strips. The importance of this stage of work cannot be underestimated - the slightest defects and irregularities will spoil the interior of the room.

You can begin installing straight skirting boards only after all corner elements have already been cut and installed. Before work, the products themselves should be carefully inspected, measured and modified if necessary - often skirting boards are cut unevenly during the production process, so their edges have to be aligned yourself.

The joining of ceiling plinths on straight sections looks like this:

When corner strip assembled, you need to attach straight skirting boards to it on both sides so that they are located close to each other. Further this operation will be repeated with the rest of the details.
At a certain point, the straight bar will reach the corner opposite to the one from which the installation began. At this stage, the smooth plinth must be marked and cut in accordance with the mark. To ensure that individual parts match perfectly on straight sections, it is worth sanding their edges with fine sandpaper.
When joining skirting boards, you must use an adhesive suitable for the specific material. The planks must be pressed well, but carefully during installation, so that excess adhesive composition came out. Excess glue can be removed with a dampened rag - just be careful not to smear it on the wall and ceiling.
Having installed all the parts in their places, all that remains is to process all the cracks and gaps using a special sealant or putty. Ceiling plinths can be left in their original form, or they can be covered with a layer of paint.

Conclusion

Joining ceiling plinths is a task that is quite suitable for doing it yourself. To decide correctly this task, you need to prepare materials with tools in advance and figure out how to connect ceiling skirting boards at corners and straight sections.

Installation of a baguette is final stage finishing the ceiling, and allows you to hide its junction with the wall, giving the interior a certain completeness. At first glance, it seems that joining ceiling plinths is a simple matter, but there are some difficulties in it. Everyone who does repairs themselves, and does it for the first time, encounters them.

Most often our readers ask the question: “How to join the corners of the ceiling plinth?” We will try to answer it in as much detail as possible and will offer a video on this topic.

The role of ceiling plinth in the interior

Baguettes, or fillets as they are also called, are an integral part. And it doesn’t matter what method of finishing the ceiling was used: plastering the base base, or installing a suspended structure.

In other cases, cornice strips are installed, the type of which is selected depending on the materials used in the decoration of the walls and ceiling. If the ceiling is lined with boards, or the walls are lined with wooden panels, wooden cornices look most harmonious.
, assumes that the finishing of its junction with the wall will be done in the same style. There is also polyurethane stucco, and this option can generally be called universal. Polyurethane skirting boards have incredible flexibility, which allows them to be used even on spherical surfaces.
By the way, in the photo above you see that they were used to finish the levels. The most popular option can be considered polystyrene foam cornices, and not because they are in any way better than polyurethane skirting boards.

In this case, the main criterion for the buyer to choose a material is its low price. If we talk about quality, then, in terms of its operational and aesthetic indicators, polyurethane baguettes are unlikely to compete with anything.

Design features of fillets

The principle of installing skirting boards does not depend on the merits of one type or another cornice strips. Whatever products are used to frame the ceiling surface, the joining of the plinth is done using the same technology - even when it is planned to install curtain lighting. It’s just that the baguettes in this case are somewhat different from traditional options by configuration.

An ordinary plinth is a strip of a certain width, which, when installed at a joint, has one edge adjacent to the surface of the wall and the other to the ceiling. Inexpensive options for rooms with low height, have simplest form, and geometric relief or pattern with front side.
For high ceilings, there are cornices of more complex designs on sale. They have a stepped configuration, which allows you not only to hide the junction of the ceiling with the walls, but also to give it the shape of a coffer. In the example above you can see one of the options for such skirting boards.

Their design features They also have fillets designed to illuminate the perimeter of the ceiling. They are usually mounted not at the joint, but on the wall.
This plinth can also be used as a cable channel for laying any other communications: Internet, telephone, air conditioning, video surveillance, etc. Baguettes intended for LED strip, slightly different in shape.
They have only one rib adjacent to the base. The second side is located at a certain distance from the wall, due to which the light from the LED strip glued to the wall penetrates into the room.

The joining of ceiling plinths of this type does not have any special differences, and is carried out using a technology that we will discuss in the next chapter.

Ceiling perimeter framing

The more complex the cross-sectional configuration of the plank, the more attention and accuracy the joining of the ceiling plinth requires. To execute this work with your own hands, and to do it efficiently, it is important to follow the technology.

One wrong cut is enough - and gaps form at the junction of the planks, which cannot be repaired later. We hope that the instructions on the topic: “How to join a ceiling plinth” will help you cope with this task.

The gluing of cornices begins when the installation of the structure or finishing of the base surface of the ceiling is completed. As for the walls, at the time of installation of the baguette strips they must be leveled and painted. If they are going to be covered with wallpaper, they do it last.

Preparing for work

Before joining the ceiling plinths, you need to purchase a miter box. This tool will allow you to cut planks with maximum accuracy at an angle of 45 degrees, which, when combined, form a right angle.

A miter box of the simplest design is suitable for this purpose, and it will cost no more than seven hundred rubles. During the repair process, the tool can come in handy more than once: when joining door frames; installing parquet or laminate on the floor, covering walls or ceilings with boards. So, the money will be well spent.

In the absence of a miter box, you will have to arm yourself with a protractor and a ruler, and mark the cutting lines with a pencil. Just keep in mind that if the plinth has an internal cavity, it is almost impossible to cut it straight using improvised means.
As for the tool you will use for cutting, select it depending on the type of baguette. If it is polystyrene foam, then a stationery knife with a wide blade will work perfectly. You won’t be able to cut wood or plastic with a knife—at a minimum, you need a hacksaw.
The greatest cutting accuracy is obtained only in a miter box, and when using a circular saw or jigsaw. We don’t think that if you purchase expensive polyurethane skirting boards, you will want to cut them with a utility knife, risking getting an uneven joint. By the way, when working with a hacksaw, the edges turn out to be torn, which also does not contribute to a high-quality result.

Skirting boards of complex configuration, which were discussed in the previous part of the article, are often sold with corners already prepared for joining. They are very convenient to install when the room has bay windows, niches, columns - that is, many external and internal corners.
The corner plinth is cut only when it is necessary to make a simple end connection in a straight line. Agree, this is much easier to do than cutting a corner correctly. It should not be surprising that such products cost an order of magnitude higher than ordinary planks with straight ends.

In any case, the surface on which the plinth will be mounted must be smooth, dry, and free of dust. In addition, to prevent the glue from being absorbed into the base, it must be primed.

Cutting secrets

Armed necessary tools, you can start working. Installation begins from the corner closest to the entrance. Most often this is an internal corner.

In order to properly join the plinth in it, the cut is made not from the back, but from the front side. To join in an outer corner, you need to cut from the inside.

The lack of professional tools complicates the work, especially since geometrically even corners in apartments are very rare. To repeat the outer or inner corner, you need to make a stencil out of cardboard, outline the contour of the corner, and then make a cut along it.
If the deviations are minor, or the angle is non-standard, you can simply try it on. By the way, the picture above shows the sequence of your actions - from fitting to cutting. On her Special attention paid attention to the correct placement of the baguette strip in the miter box.

The basis is taken from the internal corner, which is found in any room. In this case, the bottom edge of the strip cut at the desired angle is longer than the top side. In the case of an outer corner, the opposite is true. The cut slope on the left corner element is made to the right, and on the right bar to the left.
Before you start gluing, you need to try on the strips by applying them to the corner for which they were cut. If the angle exactly corresponds to 90 degrees, then there will be no problems during joining. A slight discrepancy in the cut caused by unevenness of the base can be eliminated with the help of a knife.

With outer corners, everything is much simpler: attach the plinth to the joint, draw a line along the contour with a pencil, along which you make the cut. You just need to keep in mind that at the time of fitting, the second end of the plank should already be adjusted to the previous plinth, or cut to an internal angle if you need to bypass a protruding architectural element.

Installation of skirting strips

In old houses, there are often rounded joints between the ceiling and the walls, and there are simply no corners as such. These options are the most difficult. If the rounding of the corners is insignificant, the planks are joined using a triangular insert cut from a piece of plinth.

You can also use special corner elements that are commercially available, with which you can hide an uneven joint. If the curves are like those in the picture below, only polyurethane moldings will help out. Depending on the height of the room, it is better to mount them either on the wall, below the beginning of the rounding, or on the ceiling - where it ends.

As shown in our example, moldings can be glued vertically, extending to the ceiling. They do this so that, repeating the smooth transition from ceiling to wall, they visually distract attention to themselves. The harmony of this design will be helped by the contrast of the plinth in relation to the walls, or some interesting combination paints used in finishing.
The joining of the plinth on straight sections is carried out after all the corners are lined. That is, if there is a need to insert a short section, then it falls in the middle of the length of the wall. The ends of the cornices initially have right angles, so joining them together is not difficult.

If you need to cut off a piece, you can also do this using a miter box or a square. During installation, glue is applied not only to back side strips, but also the abutting ends are coated. Just before this, it is advisable to sand them with fine sandpaper.
Install the baseboard with glue applied to it in the desired position and lightly press it to the base. Any excess glue that comes out should be immediately wiped off with a napkin. Then, in order to avoid spontaneous changes in position, the baguette must be secured with masking tape.

After the glue has dried, the tape can be removed and the joints of the ceiling plinths can be sealed with white sealant. Expanded polystyrene planks are usually subsequently painted. Polyurethane skirting boards are often left in in its original form, since they have a perfectly smooth, snow-white surface, and are pleasantly pleasing to the eye even without any finishing.

Ceiling plinth is a product that in appearance is no different from its analogue floor coverings. It is also called fillet. This detail serves to mask the joints between the wall and ceiling. It is installed at the very end finishing works, since the element does not carry any functional load, but only plays decorative role. The process of installing the product is not at all complicated, but many are faced with the dilemma of how to make a corner of the ceiling plinth. Depending on the selected materials and tools that are available, the fillet corners are cut in different ways.

Creating fillet corners

To connect two planks, you can use decorative corners for ceiling skirting boards. But in the absence of such, the material will have to be processed. Next we will talk about how to correctly cut a corner on a ceiling plinth.

How to use a miter box for processing

A miter box is one of the simplest carpentry tools used to make trimming various products from different angles. It is usually a plastic, metal or wooden tray with several slots in the walls. IN simple version There are slots for 45 and 90 degree angles only. In more complex ones, there are more angles, and professional tool equipped rotating mechanism, which allows you to direct the cutting element at any angle. The principle of operation is simple: before cutting off the corner of the plinth, the workpiece is secured in a tray and then processed cutting tool(knife, saw, etc.), lowering it into the slots.

Trimming ceiling plinth using a miter box

How to properly cut a ceiling plinth for internal corner on the miter box:

The first step is to attach the plinth to the surface and mark the required length with a pencil.
Then the part is placed in the tray so that its current position coincides with the position on the surface.
Using a clamping mechanism, the plinth is fixed to the far wall of the tool container.
The product is taken with the left hand. After which you need to select correct position cutting element (angle 45 degrees). In this case, the handle of the tool should be as close as possible to the left hand.
Applying light pressure on the part, begin trimming. It is important not to press the product too hard, otherwise you may deform it.
The same manipulations, only in mirror image, must be carried out with the second baseboard.

Then the cut strips must be checked for correct processing. To do this, it is enough to connect the ceiling plinth by simply attaching the strips to the surface. If a wooden product is used, it will most likely have to be further processed with a file.

On a note! First of all, it is necessary to design the internal corners on the ceiling plinths, only after that proceed to the external ones. Otherwise, the length of the purchased strips may not be enough.

How to properly cut a ceiling plinth for an outer corner:

Before cutting the corners, you need to attach the fillet to the edge of the wall so that the product extends slightly beyond the boundaries of the surface, and make a mark.
Then perform the same operations as in the previous instructions.
At the end, make a fitting and, if necessary, further process the edges with a stationery knife or file.

Important! To cut the corners of skirting boards using a miter box, you need a perfectly even surface angle of 90 degrees. If there are any unevenness on the walls, due to which there will be deviations of more than 2 degrees, you will have to use other tools.

Processing fillets using markings

Most often the result final leveling are straight angles. But in some cases, the deviations are so large that even after fitting and filing the fillets, gaps remain. And then the question of how to correctly cut the ceiling plinth using a miter box will be meaningless, since in this situation it is better to cut the planks with preliminary fitting on the spot. To carry out this procedure you will need the following:

A thin hard pencil or marker (this tool leaves clear lines, so you don’t have to look closely).
A small fragment of a fillet.
Ruler or tape measure.
A special construction or stationery knife for processing polystyrene, polyurethane or PVC baguettes.
Saw or hacksaw for processing wooden baseboards.

Before cutting the ceiling plinth, you need to lean the strip against the corner and draw a line along the outer edge of the product on the ceiling surface. Then attach the same fillet fragment to the opposite wall and draw the same line.

As a result, there will be an intersection on the ceiling surface, where the cut products will need to be joined. The resulting mark is alternately transferred to the parts that will be joined.

Then you need to take a ruler and connect the edge of the fillet with the markings. After which the product is placed on the table and cut along the line.

This method is quite simple, but it comes with some risks. As a result, the inside of the baseboard can interfere with the connection of the parts on the surface. To prevent this from happening, you can do the following: before cutting the ceiling plinth in the corners, it must be placed on the table in the same position in which it will be glued to the wall. Then cut the outer corner or inner corner at a 45 degree angle. The next plank should be processed in the same way. In this way, lengthy processing after fitting can be avoided.

Next, you need to adjust the joint, but already at the place where the fillet is installed. That is, before gluing the ceiling plinth in the corners, it is necessary to check the internal joint without applying adhesive or fasteners. Then carry out the same manipulations for the outer corner planks. After preliminary fitting and bringing the angles to perfect condition, you can glue products.

Now the question of how to join ceiling plinths at uneven corners should not arise.

Trimming with a square

Now let's look at how to cut a ceiling plinth using a standard set of tools. For this you will need:

ruler or tape measure;
square;
construction, stationery knife or hacksaw.

How can you cut off a corner of a ceiling plinth if the surfaces are perfectly flat:

A ruler is applied to the fillet at an angle of 45 degrees. Using a knife, cut off the unnecessary fragment with one movement of the hand.
In the presence of wooden product, markings are first applied to the plinth with a pencil, and then sawed off with a saw or hacksaw.

If the surfaces of the walls have unevenness, then the first thing you need to do is measure the degree of the angle, and then divide it by two. Let's say the angle is 80 degrees, which means that each product needs to be cut at an angle of 40 degrees.

If adjacent walls do not form a right angle, then to cut the baseboard you will have to make some calculations

Decoration with decorative corners

The easiest way to join ceiling plinths in the corners is to use special products. They are sold in hardware stores and are immediately ready for use. The fillets are simply glued to the surface, and the joint is closed decorative element. In this case, the question of how to properly cut the baseboard does not make sense. Even if the joint turns out to be uneven, this defect will be hidden by a decorative corner.

How to replace a miter box with improvised means

How to make the corners of a ceiling plinth using improvised means? There are several ways:

First way. It is necessary to prepare three wooden boards the same thickness and width. Using nails or self-tapping screws, connect them into a U-shaped structure. Mark the 45 and 90 degree angles (you'll need a square or protractor for this) and then make the cuts using a wood saw. The result will be a homemade miter box. How to trim ceiling skirting boards using of this instrument, stated above.

Second way. In this case, before cutting out the ceiling plinth, you should build simple design to hold the fillet. To do this, you need to take two boards and put together a corner from them. Then take the paper and draw lines on it going under different angles. Now let's look at how to cut corners using the resulting tool:
- the fillet is laid on a wooden corner;
- in the marked place - a template with drawn lines is applied to the product and trimming is carried out.

Third way. This method is the simplest, but it requires some experience and a steady hand. In this case, you can use any structure that has a right angle, for example, a table.

On a note! Before cutting the corner, measurements should be taken at the fixation site. To mark the inner corner, start measuring from the joint of the walls. Before cutting the outer corner, it is necessary to apply markings taking into account that the product will extend beyond the boundaries of the surface by its thickness.

Installation of skirting boards

This operation will be successful if you follow several recommendations:

Installation ceiling fillets It starts with the design of the corners. After completing this operation, you can begin installing the remaining parts.
When fixing the products, it is necessary to press their edges so that there are no gaps left. In this case, excess glue should be removed immediately so that it does not have time to dry.
If you purchased a PVC skirting board, you can use it to fix it. finishing putty, which may have remained after finishing work.
Before gluing the skirting boards to the ceiling, it is necessary to treat the surfaces with a special primer or just water. Then the fillets are put in place and wait until the surface underneath them dries. At the end, the seams and cracks are sealed with sealant or other material with a similar composition. It is better to use sealants containing acrylic.

Installing ceiling plinths is a fairly simple procedure that even a novice master can handle. The main thing is to follow the above recommendations and regularly check the correct installation using a level, even if the fillets look perfectly even by eye. It is also important to remember that this element is purely decorative, so even the smallest mistakes are unacceptable.
