Using liquid cork for interior decoration. Instructions for using liquid cork sealant Cork filler for seams

One-component cork sealant “Bostik” 3070 (manufacturer - France)

This is a composition intended for heat and sound insulation and filling of joints (cracks), consisting of cork granules and an adhesive elastic component containing a solvent.

Cork sealant“Bostik” 3070 is a sealing composition based on cork chips and an elastic component that glues cork particles together. Designed for filling voids, heat and sound insulation of premises ( window frames, doorways, cracks in timber and logs), as well as for decorative purposes. After application, an even elastic seam is formed. The insulating effect is ensured by the presence of air cells in the cork material.

The sealing composition “Liquid Stopper” (can be purchased wholesale and retail) has the following useful properties:

• Has excellent soundproofing effect;
• Simple and universal to use (see instructions below);
• Weather resistant;
• Does not shrink;
• Frost-resistant.

Technical characteristics of the “Liquid Stopper” sealant:

• The base of the sealant is cork granulate, saturated with an adhesive;

• Wepost Wood, Cork sealant, Test results, Warm joint

A couple of times a month we are faced with the question “is cork sealant suitable for sealing a log house using the “warm seam” technology” - We figure out what and how.

We don’t know why or who started the myth that cork sealant is used to seal crown joints.

We explain why:

Cork sealant is cork chips joined with a binder.

The cork itself does not stretch. When logs dry out, they shrink - they move. The sealant moves with them.

Since cork sealant does not stretch, it cracks.

It should also be noted that manufacturers of cork sealants do not provide data on tensile strength and peel strength, shyly hiding behind the inscription "under study" We conducted two tests.

Household, which we held in our office.

Professional, carried out in a durability laboratory building materials and sealing, using special equipment.

Household test

Now for a minute of tediousness about the description of the experiment.
You can conduct a similar test at home if you wish. There is nothing top-secret or confidential here.

1. We take two meter-long boards of the same thickness (preferably hewn).
2. Let's take two door hinges. We have the same dimensions and twist the boards together.
3. We leave a gap of 5 mm (as in real houses) - this is what we will seal with sealant.
4. Apply sealant to the seam. By technology. If you are a perfectionist and want to do everything neatly, you can use masking tape for a perfectly even application.
5. We wait until it dries (a day or two, or leave it for the weekend).
6. We bend two boards. Let's see what burst and where.

Test sealants in applied state

The photo was taken after the test and is shown to show how the sealants were applied.

Reverse side of the test bench

On the reverse side, the seam is sealed with Vilaterm cord, as required by technology.
There have already been problems with the Isocork sealant.
In a thin layer it fell inside the seam and tore easily. I had to apply it in a thick layer and without sealing cord.

Loops allow you to simulate seam movements - thereby checking which sealants break and which do not.

Cork sealant thickness

As a result, the isocork layer turned out to be very thick.
It’s probably good - more sealant more strength clutch, and more alleged strength.

Wepost Wood layer thickness - 3 mm

Wepost Wood sealant was easy to apply thin layer 2-4 mm.

Conclusion from a home test:

Cork sealant- did not pass the tensile test.

But this result was expected. Cork sealants are cork chips in a siliconized binder.

When stretched, the crumbs easily tear apart from each other (due to the low adhesion area), thereby the seam easily breaks with even slight movements.

Remember that if you cut the fabric, it tears easier. - Same with cork sealant. It begins to tear from the place where the crumbs and binders are loosely connected to each other.

Because of high density sealant itself, rupture occurs along the entire length. And from cycle to cycle of stretching, it breaks more and more.

Separately, it is worth noting that the cork sealant was applied in a dense, thick layer.

But!!! On our own behalf, we can praise cork sealant for its good adhesion to wood. It was much more difficult to tear it off the board than regular sealant. wooden house.

Sealant for a wooden house stretched, but when returning to its normal state, a small fold remained.

With proper force, it comes off easily, but does not tear along the entire length.

Sealants like " liquid plug» have earned universal recognition due to their efficiency, reliability, durability, and versatility. Such tools are quite easy to use and do not require correct application especially subtle skills or, especially, special education.

« Liquid plug» characterized by the properties of effective adhesion to the most different surfaces, used in construction, repair and finishing (wood, concrete, OSB, DSP, glass, ceramics, PVC, metal, etc.).

For maximum effect, the surfaces to be treated must first be cleaned of dirt and dust, optionally moistened with water - this will prevent excessively rapid removal of moisture from the body of the sealant and will most positively affect the uniformity of drying of the filled “ liquid stopper» seam.

Step-by-step instruction

Step 1: Clean the contact surfaces from dirt, dust, grease and other foreign elements.

Step 2: Prepare special devices: spatula, gun closed type, a trowel for smoothing and compacting the seam, a moistened sponge to remove excess " liquid plug».

Step 3: Mark the edges of the seam using masking tape. Using a gun, evenly distribute the sealant inside the seam (if wide seam for large volumes, you can use a spatula). Smooth out " liquid plug» in the seam using a trowel (the trowel can be moistened with water during the process). Remove excess sealant using a damp sponge.

Step 4: Dry the filled joint. The time for complete drying depends on the thickness of the layer, humidity and temperature of the environment. On average, drying time is 24-48 hours.

If work is carried out outside, the seam must be protected from precipitation until the sealant has completely dried. Work should be carried out at an ambient temperature of +5 degrees.

Attention! After the “liquid plug” has completely dried, it can only be removed mechanically. In this case, you should be careful and careful not to damage the seam edges and adjacent bases.

Step 4: Wash tools with warm water, optionally with soapy water.

Safety

« Liquid plug" - fully safe material. It is non-flammable and non-toxic. There is no need to use tools when carrying out work personal protection. Keep out of the reach of children. Avoid contact with eyes. If the sealant comes into contact with the mucous membrane of the eye, rinse it big amount running water, then consult a doctor.

Consumption

Flow volume " liquid plug» directly depends on the characteristics of the seam filled with sealant. Approximately the briquette consumption should be calculated for 5 linear meters with a seam cross-section of 10x10 mm.

Storage and transportation

During the production process, the sealant " liquid plug» mainly packaged in 500 ml briquettes. Supplied in group corrugated cardboard packages of 40 pcs.

Transportation and storage of sealant is allowed only at “plus” temperatures. Guarantee period Storage period is 12 months (in original packaging). An unpacked and partially used briquette should be tightly closed and reliably protected from air access.

For those who are in the process of renovation, the building materials market offers materials for every taste and budget. Among them, liquid plug is not the least important. This material is a crushed suspension of balsa wood chips in a binding glue.

Liquid cork can be used as a sealant, sound insulator, insulation, and also as a material for cladding interior walls and facades.

This material can be used wherever it is necessary to ensure noise insulation, tightness, and thermal insulation. The sealant will cope with these tasks perfectly. In addition, the conditions for working with liquid plug are quite simple, so you can handle it yourself without the help of a specialist.

Sealant based on liquid plug

Advantages

Liquid cork sealant can be used in many areas of construction and repair. In addition, it has the following advantages:

• naturalness of the material;
• resistance to mechanical stress;
• high thermal insulation properties;
• resistance to temperature changes;
• elasticity;
• high adhesion to various materials.

Liquid cork does not shrink, so it can be used without fear of damaging the finish.

Rules for joining different coatings

Often during repair work there is a need to join different finishing coatings, while the transition should be smooth and discreet. Depending on the purpose of the room, certain material is placed there. For example, tiles are installed in the kitchen, and laminate flooring is installed in the hallway.

Sometimes different materials are placed in the same room to divide the room into work and guest areas.

Liquid stopper for laminate and tile joints is one of the options for connecting these coatings. This job is simple, but requires preliminary preparation seams. First, the seam is treated with oil and then filled with liquid cork. After the material has dried, the residues are carefully removed with a knife, and then the surface of the seam is sanded. These simple steps will help make the seam between different types of coatings neat and inconspicuous.

For joints

The parameters of liquid cork sealant allow it to be used for sealing joints between any coatings or a coating and a wall. Liquid cork will create a reliable and elastic adhesion between coatings, which is not afraid of either deformation of the coatings or temperature changes.

This sealant can also be used to insulate window and door openings. If drafts are a concern, then treating the slopes of a window or door will help solve this problem.

For joints it is best to use bostik 3070 sealant, which is recommended to be protected from atmospheric exposure elastic sealants.

For facades and interior walls

An excellent solution for finishing the facade would be to use soft cork. Thanks to its properties, the connecting material will prevent the façade surface from becoming dirty and will protect against moisture, noise and vibration. Besides appearance the facade will look natural and quite rich, despite the cheapness of the material.

For those who decide to change their usual wallpaper for something more original, liquid cork for interior decoration it will come in handy. Internal walls will not only acquire an attractive appearance, but will also help protect the room from noise and moisture.

Liquid cork is applied to the walls using special equipment that sprays the material under pressure compressed air. The color range of the liquid stopper is also pleasing, allowing you to choose a color according to your preferences.

For parquet

When laying parquet, the problem arises of sealing the gaps between the wall and wood covering. After all, during operation, parquet can change under the influence of temperature and moisture. Cork sealant can easily solve this problem. Due to its inherent elasticity, liquid cork allows parquet flooring to expand or contract depending on conditions without creating gaps.

If the parquet has been lying around for a long time, then liquid cork will help eliminate cracks in the coating that have arisen over time. The sealant will help remove not only cracks in floor covering, but the consequence of these problems is the creaking of the parquet.

Common mistakes during application

At independent use When using liquid stopper, it is important to take into account the nuances that will help prevent mistakes when working with this material.

1. Firstly, before use, you should carefully prepare the surface from moisture, dust, and grease. Otherwise, contamination will reduce the adhesion of the sealant.
2. Secondly, after applying the liquid plug, its excess should be cleaned off immediately, otherwise it will harden and will need mechanical removal. This can lead to damage to the coating and seam edges.
3. Thirdly, you should not level the liquid plug on a surface that is higher than the level. Otherwise, there may be a lack of a tight fit and the presence of gaps.
4. Fourthly, the material is not used to seal the joints of carpeting with other coverings.

Liquid cork sealant can be safely called universal material. The range of its applications is quite wide: from wall decor to sealing seams. By purchasing sealant at an affordable price, you get excellent quality material with characteristics no worse than expensive analogues.
