How to glue polystyrene on walls. How and how to glue polystyrene to various surfaces

Polyfoam is an excellent sound and heat insulation material. It and its varieties have become very popular among consumers relatively recently. Manufacturers, taking into account the needs and financial capabilities of buyers, produce expanded polystyrene boards of various thicknesses. Insulation is used for finishing residential buildings and apartments, loggias and balconies, garages and sheds, warehouses and premises of budgetary institutions. For fixing the insulation boards, foam glue and mounting nails, or, as they are also called, "umbrellas", are used.

Properties of foam boards

There are a number of other materials that can keep your home warm and insulate the room from unwanted sounds. However, foam has some advantages over its counterparts:

the lightest material;
easy to install;
inexpensive;
practical;
copes with the functional purpose;
does not absorb moisture;
resistant to mold and mildew;
durable.

Extruded polystyrene foam is akin to conventional foam, but its density and performance characteristics are much higher than the properties of the latter. However, for its installation, the same glue is used as for the foam.

How to fix the insulation

When the decision is made to insulate the room, the first thing is the task: how to glue the foam? On the building materials market, consumers are presented with the widest selection of adhesives for fixing polystyrene foam boards. There are ready-made foam glue in cylinders, which is used with a special construction gun, and facade glue for expanded polystyrene in the form of a dry mixture, packaged in moisture-proof bags weighing 25 kg. One cylinder is enough to glue about 10-12 m2 of foam, while the consumption of a bag of dry mix is 5-7 m2 when applied continuously to a sheet. The price of both materials does not differ significantly. It is worth noting that the consumption of glue for foam, both foam and mixture, may depend on the degree of unevenness of the wall, the thickness of the layer and the method of its application.

In addition to structure and composition, adhesives for extruded polystyrene foam and regular foam are distinguished by temperature regime application. There are building mixtures for summer use at air temperatures from +5 to + 35 ° C and winter - in the range from -10 to +5 ° C. Both types of mixtures can be used both outdoors and indoors.

Mounting methods

Consider the question of how to glue polystyrene to a wall made of concrete, brick, wood. There are two methods for attaching styrofoam to walls:

Installation by gluing

In the first method, which is practiced for indoor insulation, polystyrene glue is applied directly to the insulation boards. Before gluing the foam to the wood, the surface should be treated with an antiseptic. A concrete or brick wall must first be cleaned of dirt and dust.

If the selected material for the installation of the insulation is foam glue for foam, then a layer of foamed adhesive is applied:

along the perimeter + along the diagonals;
along the perimeter + along one strip in the middle of the sheet.

A small amount of glue should also be applied to the edges of the foam.

Watch the video:

you do not need to apply glue to the wall;
the plate with foam glue should not be attached to the insulated surface immediately after its application. Before gluing the foam to concrete or other surface, set the sheet with the adhesive applied to the side. A couple of minutes later, the expanded polystyrene plate is pressed against the wall and held for several seconds;
the excess glue that has come out should be immediately removed with a narrow spatula.

If the fastening is carried out using a building mixture, then the glue is applied using a notched wide trowel. The adhesive layer will depend on the gap between the teeth of the tool.

Subsequent work on insulation is similar to that described above. If the question arose of how to glue the foam on the ceiling, then there are no special differences between the insulation of a sheer wall and a horizontal surface.

Mixed method using both glue and umbrella nails

The second method is used when insulating walls outside the room. In addition to the glue mixture or foam, the insulation sheets are additionally fastened with umbrella dowels. In this case, the important thing is that it is necessary to nail down the foam only 2-3 days after gluing. The glue layer should dry out and then the slabs will not move when they are reinforced with dowels. The number of nails per sheet is at least five pieces, and their length will depend on the thickness of the insulation. This method is the most reliable method for fixing polystyrene foam boards. In the question "how to glue the foam to the concrete on the ceiling?" it is better to use the second installation option.

After gluing the insulation to the surface of the premises, a plaster adhesive mixture for expanded polystyrene is used. It is designed for gluing reinforcement plastic mesh and plastering of insulation boards.

How to choose glue

To make the right decision in choosing an adhesive for expanded polystyrene insulation, it is necessary to weigh the pros and cons. The first points that should be taken into account are the price of glue, the volume of its packaging, the area of the insulated surface, the place of work (inside or outside the room).

The video will help with the choice of glue:

Insulation of small areas

What glue should be used to glue the foam, if it is necessary to insulate a small area of the surface, for example, a slope around a window? It is not advisable to buy a 25 kg bag of dry mix. Moreover, the process of using a building mixture entails additional work on cleaning the premises. A bottle of glue-foam for insulating one slope will be too much. Therefore, it is worth considering an analogue in a smaller package. In this case, you can get by with a tube of liquid nails or silicone sealant, which have recently begun to be produced in small tubes that look like hand cream. Such glue on the insulation is easily squeezed out without using a construction gun. Another alternative in insulating a small indoor area is glue in plastic bottles that do not contain acetone or gasoline, which are not “friendly” with polystyrene and its analogues.

Thermal insulation of large rooms

In the case of insulation of large rooms, of course, it is worth resorting to glue-foam cylinders or dry glue mixture. The advantage of the foamed glue is the comparative cleanliness after the work performed, the disadvantage is the air spaces between the wall and the insulation board. Some experts are inclined to think that not a continuous application of glue to the surface of the foam, makes it possible for condensation to form under the insulation and the appearance of mold there.

Dry assembly glue, when insulating impressive areas, is somewhat more economical than using foam. And the ability to cover a sheet of expanded polystyrene completely excludes the ingress of air under the insulation. But you will have to do additional work to clean the area after warming. When choosing a dry assembly glue, do not forget that it is based on cement, on the brand of which the quality of the glue itself will depend.

Can two boards be glued together?

Sometimes, to increase the thickness of the insulation, two foam plates are glued together. To solve the question: how to glue the foam to the foam, you should not resort to foam.

It expands and can subsequently deform both sheets of insulation. For these purposes, it is better to use polyurethane foam adhesive. But it is worth noting that buying a thickened sheet at once will cost less than gluing foam.

Now you know what kind of glue to glue the foam and, after weighing all the pros and cons, you can choose the most rational method gluing this insulation. At first glance, gluing foam does not seem so difficult, but it would be better to resort to the help of specialists.

Extruded polystyrene foam has deservedly gained fame as a very popular thermal insulation material. Expanded polystyrene can be used for interior and exterior work. Successfully extruded polystyrene foam is used for insulating building facades, basements, basements, balconies, and insulating premises from the inside. This foam has whole line advantages when compared with other heaters. It does not absorb moisture, does not deform (does not compact) over time, is light and very durable, has a long service life, and is not a favorable environment for the life and reproduction of colonies of microorganisms.

For a more reliable fixing of expanded polystyrene, use two methods at once: landing on glue and fixing with dowels.

Getting ready to glue polystyrene foam

For fixing expanded polystyrene, a method of gluing with glue or special mastic is used, as well as fixing foamed insulation boards to the insulated surface with dowels. The safest option is to combine the two. In this case, the plate of extruded insulation is first glued to the surface, and only after that it is fixed with dowels. This means that for work you will need:

tape measure (for taking measurements);
drill and hammer (for fastening with dowels);
roller (for preliminary surface priming);
spatulas (including notched spatulas for applying mastic or glue);
electric mixer (for mixing glue).

When choosing an adhesive, you need to determine what properties this material should have. An ideal adhesive for bonding extruded polystyrene foam:

suitable for outdoor use (pay attention to resistance to low temperatures);
sets quickly;
provides reliable adhesion of the glued surfaces;
easy to use.

Back to the table of contents

Adhesive mixtures based on aggressive solvents are not suitable for working with expanded polystyrene, since they destroy expanded polystyrene (dissolve it).

For installation of expanded polystyrene, do not use glue with aggressive components - they can destroy this material.

When choosing glue for expanded polystyrene, make sure that it contains not only gasoline and
acetone, but also all kinds of ethers and other similar substances. Therefore, you need to choose adhesives or mastic based on plasticizers, bitumen, composite mixture.

Craftsmen and just experienced builders quite successfully use such means as liquid nails, sealant (meaning silicone), frost-resistant glue for finishing facade works, adhesives for ceiling tiles, frost-resistant and water-resistant adhesive mixtures for working with tiles... The listed adhesive mixtures do an excellent job with the task. They can be successfully used, especially if they are available (that is, you do not have to bear additional financial costs), and additional fastening with special dowels is planned. But there are adhesive mixtures designed specifically for working with expanded polystyrene. Professional advice focuses on these compositions.

Such adhesives are classified into two types. The first is specialized, its purpose is gluing the indicated insulation. The second type is universal, which not only fixes polystyrene foam, but also creates a reinforcing layer.

By insulating your home with expanded polystyrene, you will get a durable insulating coating, since this material does not rot and bacteria do not grow in it.

According to their composition, adhesives are divided into bituminous and cement-polymer. Bituminous mastics
create a waterproofing layer (due to the content of bitumen in the composition of the mastic). But for this, the mastic must be applied to the glued surface without gaps. Such compositions are plastic, do not require preliminary thermal action before starting work (due to the presence of plasticizers among the ingredients, the mass retains its plasticity even without heating).

Cement-polymer-based compounds are used for both indoor and outdoor work. They are equally well suited for gluing expanded polystyrene to concrete, brick wall, foam concrete, plasterboard surfaces, and can also be used to fix the specified material on a heated surface (warm floors, for example). Cement-polymer adhesives imply a deep priming of the surface. When choosing, be careful: for external and internal work, you should choose different brands. It is hardly justified to use for interior decoration frost-resistant adhesive.

Compositions designed specifically for gluing extrusion (as it is also called) expanded polystyrene require careful preprocessing surfaces to be joined (perhaps even plastering in some cases). But the result is a reliable and durable grip. Moreover, such adhesives allow you to fix plates of extruded polystyrene foam to a surface made of brick, concrete, steel, drywall, wood. And this is not an exhaustive list.

Low cost and excellent thermal insulation properties make foam boards an increasingly popular building material. The durability of operation directly depends on the means of fixation, therefore, a problem arises of how to glue the foam, so that it performs its functions for a longer time.

The main characteristics of the foam

Before gluing to a wooden, concrete or brick surface, as well as deciding how to glue the foam together, you need to learn about the properties and characteristics of this material. Polyfoam, or, as it is otherwise called, expanded polystyrene, is formed as a result of foaming of polymers. 98% of the material is gas contained in the smallest cells with very thin walls.

Typically, foam plates are used as insulation for walls of building facades and for finishing ceilings, walls, slopes inside rooms, in basements, on balconies and loggias. Expanded polystyrene can be glued to concrete, wood, metal, brick, plasterboard and gas silicate base.

The main characteristics of the foam:

excellent rigidity with low weight;
long service life;
excellent thermal insulation properties;
resistance to moisture;
polystyrene foam with fire retardants does not burn;
when disposed of after operation does not pollute the environment;
protects from the wind if applied outside the building;
does not emit substances harmful to the human body; this material can be worked with without protective equipment;
does not dry out and does not shrink during long-term operation, resistant to temperature extremes;
it is easy to work with foam - it is easy to cut, installation can be carried out using improvised means;
molds do not develop on it;
inexpensive.

Using expanded polystyrene as an insulation material instead of wood, brick, concrete or mineral wool saves time, money and indoor space.

Foam has disadvantages:

breaks easily;
has very poor air permeability;
collapses under the action of mixtures, which include nitro lacquer;
deformed when the solvent and ultraviolet rays hit the surface.

Gluing methods and types of adhesives

You can attach foam boards to the surface using glue, dowels, or both at the same time. With adhesives, foam is usually attached indoors, with dowels and glue - when working on the facade. Fixation only by means of dowels is used in extremely rare cases, this is due to the fact that the required level of reliability cannot be achieved in this way. If the roof is insulated, then the expanded polystyrene is simply embedded in the crate.

Foam gluing is carried out using dry compounds and ready-made adhesive mixtures.

Advantages of powdered products:

excellent adhesion (adhesion) to brick, plaster, concrete, cement;
immunity to temperature changes and precipitation;
elimination of small irregularities on surfaces;
relatively low cost.

Disadvantages of dry mixes:

the adhesive composition must be prepared, it will take time, in addition, you need to know how to properly combine the powder with water in order to achieve a uniform consistency;
you will need a mixing container and a construction mixer;
dust is emitted during cooking.

Quickly and efficiently glue the foam to foam, concrete, brick and wood surfaces, OSB panels or honeycomb blocks will be allowed by ready-made adhesives. The most commonly used aerosols in cans based on polyurethane foam. Such materials are very convenient, while one cylinder is enough to glue about 10 m 2 foam boards inside or outside the building. The glue is resistant to temperature extremes and high humidity, hardens in about half an hour and reliably attaches the foam to the base.

Important
Never use mixtures containing toluene, alcohol or acetone for gluing foam plastic, as they destroy the structure of the material.
The disadvantage of ready-made adhesives is the high cost. Popular ready-to-use adhesive mixtures:
Ceresit CT 84 Express;
"Titan Styro 753";
Penosil.

When deciding how to glue the foam, you should not write off other ready-made adhesives, for example:
silicone sealant is used if it is necessary to bond small fragments of thin foam with a leveled base;
"Liquid nails" is a universal adhesive based on polymers. For example, "Montage Moment", Dragon which will connect perfectly metal base with foam. It is convenient for them to stick polystyrene foam to the ceiling.

Advice
Before gluing, clean the metal surface from rust, grease and paint.

Stages and nuances
Foam gluing is carried out in several stages:
Disconnect electrical wiring.
Remove paint, whitewash, residues from the substrate finishing materials and pollution.
Remove irregularities deeper than 1 cm, that is, level the surface. If this is not done, then the foam plates will break during installation.
Treat the surface with an antiseptic primer. This will improve adhesion and prevent mold growth.
Wait for the primer to dry.
Foam boards are usually glued from a corner or light. In the process of work, the desired configuration is given using a mounting knife.
If using aerosol adhesive, insert the can into the gun and cut off the tip. Apply the composition to the wrong side of the foam board in strips along the edges (from the very edge, retreat 2-4 cm) and diagonally. It is also permissible to squeeze out the glue with dots - in the center and in the corners.
Dilute the dry mixture with water until a homogeneous consistency is obtained and spread with a small notched trowel on the plate, a homogeneous thin layer should be obtained. Another option is to apply the adhesive pointwise around the perimeter and in the middle, evenly distributing it over the surface.
Press the styrofoam to the base and hold for a few seconds. Remove excess adhesive with a damp cloth or even trowel.
In the same way, glue the next board end-to-end to the previous one. If a gap more than 2 mm wide has formed between them, blow it out with polyurethane foam or putty.

It is necessary to press the foam to the surface as a rule, and level it with the help of a building level.
Advice
When using additional fasteners (dowels), wait until the adhesive is completely dry and only then drill holes and drive in the umbrella dowels.

How and what to glue to concrete, wood and brick surfaces
If you want to mount polystyrene foam to concrete base when carrying out external thermal insulation work, it is better to use dry compositions in the form of a powder. This is due to the fact that they have a cement component, polymers and sand, which provide reliable adhesion.
The best tools are:
T-Avangard-K;
Ceresit CT 83;
Armierungs-Gewebekleber.

The T-Avangard-K composition is suitable for fixing foam plates not only to concrete, but also to brick bases, plaster and cement plaster. The dry mix is available in 25 kg bags. One package is diluted with 5-6 liters of water. The powder is usable within 6 months from the date of issue. Summer and winter version... The first is recommended to be used at temperatures from +5 to + 35 ° С, the second - from –10 to + 5 ° С. The cost of one bag is, on average, 275 rubles.

Ceresit CT 83("Ceresit CT 83") is a high-quality quick-hardening compound that is perfect for any mineral substrates. Available in 25 kg bags, the ready-to-use mixture should be used within two hours. The price per bag varies from 413 to 539 rubles.
Ready-made adhesive mixture (glue-foam) Ceresit CT 84 Express should be used at temperatures from –10 to + 40 ° С and in conditions of high humidity. It is perfect for concrete, brick surfaces, as well as cellular blocks and OSB boards. Foam glue Ceresit CT 84 Express consists of butane, propane and polyurethane. One 750 ml bottle costs 600 rubles.
For interior decoration and insulation, roll foam is most often used. For it, it is better to use gypsum-based powder mixtures.
Gypsum Perlfix produced by the company Knauf... Packaged in bags of 30 kg. The glue will do an excellent job of gluing foam to substrates made of foam concrete, plaster, ceramic brick... It is not necessary to level the surface before using the composition. To increase the adhesive properties, foam blocks are pre-treated with concrete contact. It is not recommended to work with glue if the room temperature is below + 5 ° C. One package Perlfix weighing 30 kg costs, on average, 280 rubles.
Polyfoam is a high-quality and at the same time inexpensive building material, which is successfully and often used as insulation in almost any room. For its gluing, dry mixtures, ready-made adhesives in the form of aerosols and "liquid nails" are used. When deciding which glue is better to glue the foam, it must be borne in mind that the composition in the form of a powder will be cheaper, but the ready-made mixture is much more convenient to use. When carrying out work outside the building, on the facade, be sure to use dowels for additional fastening.

Before we figure out what kind of glue to glue the foam, let's consider its properties. Polyfoam (expanded polystyrene) is a material obtained by foaming polymers. It consists of 98% of gas, enclosed in microscopic cells with the thinnest walls.

Material in the form of slabs of various thicknesses is used to insulate the facades of houses, as well as for preliminary finishing ceilings, walls, floors, window slopes in living quarters, basements, loggias, balconies. It can be glued to foam concrete, brick, gas silicate, concrete, metal, plywood, wood, drywall, OSB boards.

The main characteristics and advantages of foam:

rigidity with low weight;
durability;
high thermal insulation properties at various temperatures;
moisture resistance;
protection of premises from wind during outdoor use;
resistance to temperature extremes - the foam does not change in size during the entire service life (does not shrink, does not dry out);
fire safety - the material does not burn (true for expanded polystyrene with fire retardants);
harmless to humans - polystyrene foam does not emit toxic substances, you can work with it without individual funds protection,
environmental friendliness - after the end of its service life, the material can be disposed of without harm to the environment;
mold resistance;
ease of installation - it is easy to cut and fix it using available tools;
low price of plates.

Using expanded polystyrene instead of the listed materials saves free space, cash and the time required for installation work.

The disadvantages of polystyrene include low mechanical strength (brittleness), inability to pass air, as well as a tendency to deterioration under the influence of paints and varnishes based on nitro-varnish, as well as various solvents and ultraviolet rays.

Fixation methods and types of glue

Understanding how to glue the foam to the wall, you should know that there are three main ways of fixing the material:

with glue;
using dowels;
with the simultaneous use of glue and dowels.

The first option is practiced more often for internal work, the third - for external work. The fixing of thermal insulation boards only with the help of dowels is rarely carried out, since it does not provide the proper level of reliability. When insulating the roof, the foam can simply be embedded in the crate.

For gluing the foam, it is permissible to use various means. All of them can be conditionally divided into two groups - dry compositions and ready-made adhesives.

Dry products

If you have a question of how to glue the foam to concrete during facade thermal insulation work, you should opt for dry mixes. They contain cement, sand and polymer fillers. Well-known means - Ceresit CT 83, "T-Avangard-K", Armierungs-Gewebekleber.

With internal finishing works dry compositions based on gypsum are used. Their main purpose is drywall installation. Popular blends are Knauf Perlfix, Volma.

To prepare the glue, the powder must be diluted with water according to the instructions. After drying, the mixture hardens, forming a strong rigid connection of the foam with the main surface.

Benefits of powdered products:

high degree of adhesion (adhesion), ensuring durable fixing of the foam to different surfaces- concrete, brick, cement, plaster;
resistance to temperature extremes and precipitation;
the ability to compensate for small irregularities in the base;
relatively low price.

Flaws:

the time spent on preparing the glue - it should be properly combined with water and mixed thoroughly, achieving a homogeneous consistency;
the need for additional inventory and tools - mixing containers, construction mixer;
release of cement or gypsum dust during work.

Ready adhesives

Solving the problem of how to quickly glue polystyrene, it is recommended to pay attention to ready-made adhesives. The main option is an aerosol product based on polyurethane foam in cylinders.

This kind of foam glue is very convenient to use. One cylinder is enough for fixing about 10 m 2 of plates. The mixture hardens in an average of 30 minutes, providing a secure hold that is resistant to moisture and temperature changes. The only negative is the relatively high price. Popular products are Penosil, Titan Styro 753, Ceresit CT 84 Express.

Foam based on polyurethane foam can be used if there is a problem than to glue the foam to foam, concrete, brick, cellular blocks, OSB panels. It is suitable for indoor and outdoor use.

Required tools

Toolbox and supporting materials required for bonding the foam depends on the fixing agent used. In any case, you should prepare:

foam of the selected thickness, its amount should be equal to the area that must be pasted over plus 10% for waste;
a small spatula and rags to remove excess glue mass, if they are not removed, hard lumps will form;
a primer for treating the main surface to which the foam will be attached;
wide brush for priming;
a knife for cutting styrofoam.

If additional fixing of the plates with dowels is planned, then you need:

hammer drill with a 10 mm drill;
a hammer;
special dowels, shaped like umbrellas (fungi).

When using a dry mix, the following are additionally required:

tap water;
plastic mixing container;
construction mixer (drill attachment);
comb-spatula for applying the composition to the foam.

If aerosol glue is used, then a special assembly gun is required, into which the can is inserted.

Stages and features of work

Let's take a look at how to glue the styrofoam to the ceiling. Main steps:

When insulating walls, the foam is glued in the same way. Usually, the sheets start from one of the corners. After applying the glue, the slabs must be pressed against the wall using the building rule, and they must be leveled. If additional fasteners are used, then it is necessary to wait until the glue is completely dry, and then drill holes and drive in the umbrella dowels.

Polyfoam is an inexpensive and high-quality thermal insulation material that is used in household construction in residential and utility rooms. To fix it, dry compounds, aerosol adhesives and "liquid nails" are used. Powdered mixtures are cheaper, but ready-made products are more convenient to use. For outdoor work, the foam plates must be additionally secured with dowels.

Such a lightweight universal material, like polystyrene, has recently become popular as an insulation material for rooms. As it turned out, it can be used both as a design element and for making small decorative items. Both the masters who insulate their home and the "homemade" ones may face the question of how to glue the styrofoam to the styrofoam.

To keep it warm and not only

Many citizens in the post-Soviet space have to live in apartments of the "Khrushchev" or "Brezhnevka" type. What good is the houses built in those distant times, besides the fact that they exist, the small area of apartments and their dense population? That's right - wonderful sound permeability of the walls! Unfortunately, not everyone likes to hear the latest neighbors' news breaking through the walls at night. These citizens are trying to separate from the collective of the house, by any means insulating their premises.

The method of insulation with foam sheets has a sufficient number of advantages. Among them are the following facts:

lightweight, almost weightless material;
has a small thickness;
has excellent sound and heat insulation properties;
easy enough to mount;
can be used both inside rooms and on the facade of houses.

Only one thing can cause controversy and doubt. This is the question of how to glue the styrofoam to the wall.

On concrete, on brick and on wood

You can attach polystyrene foam panels to almost any base. Only adhesives are not always used. Most often, both adhesives and mechanical fasteners are used. It depends on which side of the room the work will be carried out. If the sheets are mounted on the facade, then double fasteners are used: an adhesive mixture and "umbrella" dowels.

How can you glue the foam to a brick or concrete base with outside at home? The mixture must be resistant to wind and precipitation. In addition, the composition should not contain gasoline, acetone and other solvents, which will simply "eat up" the foam panel to holes.

How to glue Styrofoam to Styrofoam? It is not recommended to use for these works polyurethane foam... By swelling and expanding during the solidification process, it can deform the slabs.

When working with wood, plywood or drywall, use the same mixtures as in other cases. How can you glue the styrofoam? Usually, masters use the following means:

liquid foam;
liquid nails (specially for this material);
concrete contact waterless mixtures;
silicone sealants;
compositions for tiles;
special glue-foam.

How to properly glue styrofoam to a ceiling or wall

When working, glue is applied only to polystyrene foam tiles. The surface of the ceiling or wall must be dry and clean. The composition is placed on the sheet in stripes (for air outlet) if the area to be trimmed has an uneven texture. With an ideal base surface or foam, it is carried out along the perimeter of the tile with a small indent from the edge. A small amount of the mixture is applied to the center of the panel. When fixing large-sized foam sheets with glue, the perimeter is lubricated in a spiral, gradually approximating the center of the sheet. On the sides, the glue is applied in a zigzag manner with a thin layer.

After applying the composition, the panel should be set aside for a few minutes. After a short exposure, the slab or panel is applied to the desired place on the wall or ceiling and carefully pressed against the base and adjacent tiles, fixing it for a while. If work is being done on the ceiling, it is convenient to use a regular rolling pin. Excess adhesive is immediately removed with a spatula or other device.

When insulating the outer surface of the house, additional fastening of the panels is carried out using dowels-fungi. The seams between the tiles must be carefully filled with the same compound with which the panels were glued.

How to prepare the main surface

In order for the result to be of high quality, there is little knowledge about how to glue the foam to the foam. If the wall is crooked or dusty, all work may be wasted.

First, all pits and bulges must be removed or repaired.

Secondly, the surface is cleaned from paint residues, various peeling and remnants of glue or plaster.

Thirdly, large and small cracks are closed.

Only after thorough cleaning of any deposits, dust and dirt can you start the main work.

In the manufacture of various design stuff? The same formulations as when renovating your home.
