Sealant liquid stopper tn. Liquid cork or cork sealant: characteristics and prices. Technical characteristics of the sealant "Liquid plug"

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

« Liquid stopper » characterized by the properties of effective adhesion to the most different surfaces used in construction, repair and decoration (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 matter.

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

Step 3: Mark the edges of the seam with masking tape. Using a gun, evenly distribute the sealant inside the joint (with wide seam large volume, you can use a spatula). smooth out" liquid stopper» in the seam using a trowel (the trowel can be moistened with water during the process). Remove excess sealant with a dampened sponge.

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

If work is carried out outside the room, 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" is completely dry, it can only be removed mechanically. In this case, you should be careful and careful not to damage the edges of the seam and adjacent bases.

Step 4: Rinse the tools warm water, optionally with soapy water.

Safety

« Liquid stopper" - fully safe material. It is non-flammable and non-toxic. When carrying out work, it is not required to use tools personal protection. Keep out of the reach of children. Avoid contact with eyes. In case of contact of the sealant with the mucous membrane of the eye, rinse large quantity running water and then consult a doctor.

Consumption

Consumption volume " liquid stopper» directly depends on the characteristics of the joint being filled with sealant. Approximate consumption of a briquette should be calculated at 5 running meters with a seam section of 10x10 mm.

Storage and transportation

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

Transportation and storage of sealant is allowed only at "plus" temperature. Guarantee period storage is 12 months (in the original packaging). The unpacked and partially used briquette should be tightly closed and securely protected from air access.

Relatively recently, the market of building materials appeared the new kind plastic fillers - cork sealants, or liquid cork. It is to them that our today's educational program is dedicated, which will acquaint readers with the properties of this material, the features of choice, as well as the scope.

The composition and properties of the sealant

The practical characteristics of cork sealants are determined by its main filler - cork chips, whose share can be up to 90%. Another 5-7% of the volume is occupied by polymer binders, the rest is water, which is necessary to give the composition the desired consistency.

The quality of the raw material used as a filler determines the behavior of the sealant during operation. The cork has elasticity and elasticity, these properties are preserved after the composition has solidified. Other most pronounced features are low thermal conductivity, low specific gravity, environmental friendliness and resistance to organic damage.

The behavior of the composition during application and the scope of its application depend on the properties of the polymer binder. Most manufacturers use polyacrylate-based adhesives as the adhesive for cork granules. This is a water-soluble composition that does not contain and does not release during solidification volatile substances. Polyacrylates have excellent adhesion to most building materials and are physical properties have a great resemblance to cork chips. At the same time, the binder eliminates such shortcomings of the cork as hygroscopicity and the ability to decompose under the influence of oxidizing agents and ultraviolet radiation.

Manufacturer's choice

On the market of Russia and CIS countries cork sealant, or liquid stopper, are represented by several brands. ISOCORK and Bostik have the most expanded sales area, there are less well-known manufacturers. The cost ranges from 250-300 rubles per 500 ml when packaged in a polyethylene tube and can reach 500 rubles when delivered in syringe tubes. The choice of cork sealant on the market is significantly lower than conventional liquid cork. These compositions should not be confused: stabilizers and modifiers are added to cork plaster, which increase operational properties, however, such substances reduce the environmental friendliness of the material.

It is worth noting that the technology for the production of cork sealant is simple and therefore there are no significant differences between the products of different trademarks does not have. The choice should be made based on the cost of the material and the volume of packaging, taking into account the recommendations of contractors and the developer of the construction project.

There is also one caveat. Polyacrylates and compositions based on them are able to lose their properties over time, therefore, the less the sealant was in the warehouse, the better. It is worth asking the seller which manufacturer from his range is in the greatest demand: this sealant is imported more often, which means that there is less chance of purchasing illiquid goods.

Use in thermal protection systems

If cork agglomerate is used as a heater, there are several important requirements for the installation process. Sewing seams is a must. In hidden insulation systems, it is necessary to eliminate blowing and cold bridges while ensuring maximum uniformity of the layer. If a cork material used as a top coat or for wallpapering, it is necessary to eliminate irregularities at the joints and hide them visually.

Cork sealant copes with all these tasks perfectly. It is quite sticky and, when attached to a cork board cut, forms an almost monolithic structure. The plasticity of the composition allows you to fill the entire joint cavity and carefully smooth the surface. Most of the series of such sealants are available with an extended color map and can be easily tinted with dispersed tinting concentrates.

The installation process consists in applying or introducing a small amount of sealant into the joint, pressing it in and smoothing it out with an elastic spatula. When working with roll materials it is convenient to use a sealant packed in a polyethylene tube: the composition is squeezed out of it in small portions onto the palette, where it is given desired color and shade, then the composition is pressed into the joint with light movements of the spatula. To seal seams in black agglomerate, it is convenient to use sealants in syringe tubes: a thin nose allows you to fill the seam from the very root, and with due diligence - without excess that needs to be removed or smoothed.

Sealing building structures

Prefabricated structures from SIP or reinforced concrete panels have little stability and are prone to seasonal linear fluctuations. It is quite difficult to ensure the tightness of such buildings: most aggregates quickly lose their qualities under such conditions. Thus, the polyurethane foam most commonly used for this purpose becomes brittle over time and crumbles into gunpowder. Solid sealants, in turn, do not have sufficient elasticity and form cracks. The only one suitable material for such purposes - non-drying viscous mastics, but they do not quite fit into the environmental standards of construction, and they are expensive.

Cork sealant is well suited as a filler for joints, including locks. With its help, it is possible to achieve very high-quality sealing of the edges of sandwich panels and eliminate cold bridges at the junction points to the frame. Residents of apartments in panel houses it can also be very useful during the next repair to cut the joints between the panels and the ceiling and fill them with cork sealant, which will eliminate airborne noise, drafts and block the way for insects from neighboring apartments.

However, cork sealant is not very well suited for caulking a log house using the " warm seam". With a minimum degree of risk, it can be used for well-established houses made of profiled timber with high-quality dowel fastening. However, in log cabins twists and linear displacements are too great, while the cork sealant does not show sufficiently high elasticity and adhesion to wet wood.

Floor finishing

When laying linoleum, open joints are very popular: the absence of a threshold affects favorably both appearance and safety. To fill a seam oriented according to the pattern, can be used cold method welding using cork sealant. This is especially advantageous for thick linoleum, where the cork filler can act as the basis of the joint for the use of a thinner welding cord. The most important requirement for such an application thorough cleaning joint with a vacuum cleaner and its degreasing with alcohol.

Using the same technology, it is possible to perform a very technological sealing of the adjoining tiles to a laminate or linoleum. If the level of the finished floor is initially corrected for a single plane of coatings, this method demonstrates high aesthetics and durability. The plasticity of the seam is high enough to compensate for both shrinkage and thermal deformation of the laminate, and fluctuations from through loads. Best result is achieved provided that under the edge of the tile a groove is made in the adhesive joint, then the composition forms a reverse wedge that cannot be squeezed out.

When laying floor coverings, cork sealant is well suited for sealing the joints between floor and wall. Such termination does not prevent linear oscillations of the floor, while blocking the path small insects. Especially great is the benefit of sealing a floor insulated with mineral wool: when the floor vibrates, there is no air flow that carries small stone fibers out of the cavity.

Sealing of assembly seams

The ability of the fellem (cork) to prevent the propagation of mechanical vibrations is well known. This property is widely used in noise protection systems and cork sealant is once again used here. Most famous example- arrangement of compensation gaps between partitions and capital structures. Filling them with a liquid plug almost completely eliminates airborne noise and well prevents the spread of structural noise.

In addition, due to the elastic properties of the cork filler, the impact on the partition from building structures. When installing frames under the gypsum plasterboard, the sealant is applied to the middle shelf of the guide profiles prepared for installation. This allows you to more accurately adjust the fixing position and compensate for gaps with varying thicknesses. The joints of the adjoining partitions made of aerated concrete or gypsum blocks are filled after shrinkage of the masonry from a syringe tube, and the composition does not have to be applied to the full depth of the joint.

Application in soundproofing systems

The properties of cork granulate make it possible to use sealants based on it for joining and gluing sound-absorbing panels. The latter is also facilitated by the high adhesion of the acrylic binder to a wide range of materials.

The high density of cork sealant does not completely eliminate structural noise, however, it will not be superfluous to use cork when laying subfloor or ceiling boards. A small porous layer will prevent squeaking between floorboards and joists, and will also act as a shock absorber.

Cork sealants are also used in automotive soundproofing. The purpose is the same: sealing the joints and fixing the main blocks of the sound-absorbing filler. The use of cork filler for vibration damping is widespread: in the supports of desktop machines, small vibrating tables, when installing portable power generators. Cork sealant can also be used to make parts using mold casting, which expands the range of options for a home DIY crafter.

For those who are under renovation, the building materials market offers materials for every taste and budget. Among them, the liquid cork is not the last. This material is a crushed suspension of crumbs cork tree in adhesive.

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

You can use this material wherever you need to provide insulation from noise, tightness, thermal insulation. The sealant will do a great job with these tasks. In addition, the conditions for working with a liquid plug are quite simple, so you can handle it yourself without the help of a specialist.

Liquid cork sealant

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;
• strength to mechanical stress;
• high thermal insulation properties;
• resistance to temperature extremes;
• 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 combine 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 laid in the kitchen, and laminate is in the hallway.

Sometimes in the same room they put different materials for dividing the room into working and guest areas.

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

For joints

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

Also, this sealant can be used for insulation of window and doorways. If you are worried about drafts, then processing 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 weathering with elastic sealants.

For facades and interior walls

An excellent solution for finishing the facade would be to use soft cork. Due to its properties, the connecting material will not allow the surface of the facade to become dirty, it will protect against moisture, noise and vibration. Besides appearance the facade will look natural and rich enough, despite the cheapness of the material.

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

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

For parquet

When laying parquet, there is a problem of sealing gaps between the wall and wooden coating. After all, during operation, parquet under the influence of temperature and moisture can change. Cork sealant can easily cope with this problem. Due to its inherent elasticity, liquid cork allows the parquet to expand or contract, depending on the conditions, without forming gaps.

If the parquet has been lying for a long time, then the liquid cork will help eliminate the cracks in the coating that have arisen over time. Sealant will help to remove not only cracks in flooring, but the consequence of these problems is the creak of the parquet.

Common application errors

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

1. First, before use, carefully prepare the surface from moisture, dust, grease. Otherwise, contaminants will reduce sealant adhesion.
2. Secondly, after applying a liquid cork, its excess should be cleaned immediately, otherwise it will harden and require 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 snug fit and the presence of gaps.
4. Fourth, the material is not used joint sealing carpets with other coatings.

Liquid cork sealant can be safely called universal material. The range of its application is quite wide: from wall decor to sealing joints. Buying for acceptable price sealant, as a result you get excellent quality material with characteristics no worse than expensive counterparts.
