What can glue polystyrene foam. What can glue foam - the main types of fixation tools

Such a light versatile material, like a foam, not very long ago became popular as insulation of the premises. As it turned out, it can be used as a design element, and for the manufacture of small decorative items. Both in front of the masters that insulate their home and in front of the "self-timeline" may quell the question of how to glue foam to foam.

To be warm and not only

Many citizens in the post-Soviet space have to live in apartments like "Khrushchev" or "Brezhnevka". What is good in homes built in those distant times, except what they are, small square apartments and their dense population? That's right - wonderful sound permeability of the walls! Unfortunately, not everyone loves to recognize the last neighboring news, penetrating through the walls at night. These citizens are trying to separate from the house team, by any ways by relating their premises.

The method of insulation sheets of foam plastic has enough advantages. Among them, the following facts can be called:

• easy, almost weightless material;
• has a small thickness;
• has excellent sound and thermal insulation properties;
• quite simply mounted;
• you can use both inside the rooms and the facade of houses.

Only one can call controversy and doubt. This is the question of how to glue the foam to the wall.

On concrete, brick and tree

Attach the polystyrene foam panels can be almost any basis. Not always use only adhesive compositions. Most often used adhesives, and mechanical fasteners. It depends on which side of the room will be carried out. If the sheets are mounted on the facade, then double fasteners are used: the adhesive mixture and the "umbrella" dowels.

Than you can glue a foam to a brick or concrete basis with outdoor at home? The mixture should be resistant to wind and precipitation. In addition, the composition should not contain gasoline, acetone and other solvents that simply "eat" to the holes foam panel.

How to glue foam to foam? It is not recommended to use a mounting foam for these works. Swimming and expanding in the process of frost, it can deform the plates.

When working with wood, plywood or plasterboard uses the same mixtures as in other cases. What can be glued foam? Usually masters are used by the following means:

• liquid foam;
• liquid nails (specifically for this material);
• concrete-contact anhydrous mixtures;
• silicone sealants;
• compositions for tile;
• special glue-foam.

How to properly glue foam to ceiling or wall

When working glue is applied only to polystyrene foam tiles. The surface of the ceiling or wall should be dry and clean. The composition is placed on a sheet with strips (for air output) if the area of \u200b\u200bthe area has an uneven texture. Under the perfect main surface or foam spend on the perimeter of the tile with a small indentation from the edge. A small amount of mixture is applied to the center of the panel. When fastening the sheet foam of large sizes, the glue lubricates the perimeter on the helix, approximately gradually to the center of the sheet. On the side sides, the glue is applied by a zigzago-like thin layer.

After applying the composition, the panel should be postponed for several minutes to the side. After a small shutter speed, the plate or panel applied to the desired location on the wall or ceiling and carefully pressed to the base and to the neighboring tiles, fixing for a while. If work is carried out on the ceiling, it is convenient to use the usual rolling pin for the test. The excess of the adhesive composition is immediately removed with a spatula or other device.

When the outer surface of the house is insulated with additional fasteners of the panels using dowels-fungi. The seams between the tiles are necessarily thoroughly fill in the same composition that the panels glued.

How to prepare the main surface

In order for the result to be high-quality, little knowledge about how to glue foam plastic to foam. If the wall is a curve or dusty, all work may be lost in vain.

First, it is necessary to remove or close all the fots and bulges.

Secondly, the surface is cleaned with paint residue, various peeling and glue residues or plaster.

Thirdly, close and small gaps close up.

Only after careful cleaning from any layers, dust and dirt can be processed to the main work.

In the manufacture of different designer stacked? The same compositions as when repairing your home.

Before sorting out what glue glue foam, consider its properties. Polyfoam (expanded polystyrene) is the material obtained by foaming polymers. By 98%, it consists of a gas enclosed in microscopic cells with the finest walls.

Material in the form of plates of various thicknesses is used for the insulation of facades of houses, as well as for pre-trim ceilings, walls, floors, window slopes in residential premises, basements, on loggias, balconies. It can be glued to foam concrete, brick, gas silicate, concrete, metal, plywood, wood, plasterboard, OSB plates.

The main characteristics and advantages of foam:

• stiffness with a small weight;
• durability;
• high heat insulating properties at different temperatures;
• resistance to moisture;
• protection of winds from wind with outdoor use;
• resistance to temperature drops - Polyfoam does not change in size over the entire period of operation (not sitting, does not succumb);
• fire safety - the material is not lit (valid for expanded polystyrene with antipirens);
• harmlessness for a person - polystyrene foam does not emit toxic substances, you can work with it without individual means protection,
• ecology - after the expiration of the service life, the material can be disposed of without harm to ambient;
• resistance to the development of mold;
• ease of installation - it is simply cut and fixed with the help of available tools;
• low price plates.

The use of polystyrene foam instead of listed materials saves free space, cash and the time required for installation work.

The disadvantages of foam can be attributed to low mechanical strength (fragility), the inability to pass air, as well as a tendency to destruction under the influence of nitrola-based paintwork products, as well as various solvents and ultraviolet rays.

Methods for fixing and types of glue

Taking over how to glue the foam to the wall, you should know that there are three main methods of fixing the material:

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

The first option is practiced more often with internal work, the third - with external one. The fixation of thermal insulation plates is rarely carried out with the help of dowels, since it does not provide a proper level of reliability. When insulating the roof, the foam can simply be inserted into the crate.

For gluing foam, it is permissible to use various means. All of them can be divided into two groups - dry formulations and finished adhesives.

Dry funds

If the question arose than to glue the foam to concrete during facade heat-insulating works, it is worth stopping the choice on dry mixtures. Their composition has cement, sand and polymer fillers. Famous funds - Ceresit CT 83, T-Avangard-K, Armierungs-Gewebekleber.

With internal finishing works Dry gypsum-based compounds are used. Their main purpose is the installation of plasterboard. Popular mixes - Knauf Perlfix, "VOLMA".

For the preparation of glue, powder must be dissolved with water according to the instructions. After drying, the mixture is frozen, forming a durable rigid compound of foam with the main surface.

Benefits of powdered means:

• high degree of adhesion (adhesion), providing durable fastening of foam various surfaces - concrete, brick, cement, plaster;
• resistance to temperature differences and atmospheric precipitation;
• the ability to compensate for small irregularities of the base;
• relatively low price.

Disadvantages:

• the costs of time for the preparation of glue - it should be properly combined with water and mix thoroughly, having achieved homogeneous consistency;
• the need for additional inventory and tools - containers for mixing, construction mixer;
• isolation of cement or gypsum dust during operation.

Ready adhesives

Solving the task than to quickly glue the foam, it is recommended to pay attention to the finished adhesive compositions. The main option is an aerosol remedy based on polyurethane foam in cylinders.

Such adhesive foam for foam is very convenient to use. One balloon is enough for a fixation of about 10 m 2 plates. The mixture is frozen on average in 30 minutes, providing reliable fixation, resistant to moisture and temperature changes. The only minus is a relatively high price. Popular funds - Penosil, Titan Styro 753, Ceresit St 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 internal and outdoor work.

Other finished adhesives:

1. Silicone sealant. It is advisable to use if you need to fix small elements from fine foam on a flat surface.
2. Universal building polymer glue or liquid nails (Dragon, Mounting Moment). It is indispensable in solving the problem than to glue the foam to the metal. To improve the clutch, the surface should be cleaned from rust, paints and fat. In addition, with the help of "liquid nails" it is convenient to fix the insulation to the ceiling.

Important: For fastening foam, it is impossible to use the means having acetone, toluene or alcohol. These substances can disrupt the structure of the material.

Required tools

A set of tools and auxiliary materials required for gluing foaming depends on the fund used for fixing. In any case, you should cook:

• the polyfoam of the selected thickness, its quantity should be equal to the area, which must be saved plus 10% for waste;
• a small spatula and a rag for removing excess adhesive masses if they are not removed, solid lumps are formed;
• primer for processing the main surface to which foam will be mounted;
• wide brush for primer;
• knife for cutting foam.

If you plan to further fasten the plates of dowels, then you need:

• perforator with a drill by 10 mm;
• a hammer;
• special dowels resembling umbrellas (fungi).

When using a dry mix, additionally requires:

• tap water;
• plastic mixing container;
• construction mixer (drill nozzle);
• spatula-comb for applying composition on foam.

If an aerosol glue is used, a special mounting gun is needed, which inserts a balloon.

Stages and features of work

Consider how to glue foam to the ceiling. Main steps:

When the walls are insulated, the foam gluits the same scheme. Usually laying sheets begins with one of the corners. Adjust the plates to the wall after applying glue, you need using the building rule, align - by level. If additional fasteners are used, then it is necessary to wait for the complete drying of the glue, and then drill holes and drive the dowel-umbrellas.

Polyfoam - inexpensive and high-quality thermal insulation material, which is used in domestic construction in residential and utility rooms. Dry formulations, aerosol adhesives and "liquid nails" are used to fix it. Powdered mixes are cheaper, but ready-made means is more convenient in use. With outdoor work, the foam plates need to additionally fasten the dowels.

Heat insulation modern materials Based on creating volumes with a fixed gas environment. Enhance the already high indicators of insulation materials allows adhesive of foam on the wall. For this, glue compositions are used, both in the form of semi-finished products and ready-to-use. Before deciding than glue foam, it is necessary to understand a little in the specifics of the use of adhesive compositions.

Before gluing the foam to the wall, select the adhesive composition optimally suitable for the material of the wall and the insulation itself.

The use of foam expanded polystyrene imposes certain limitations on substances that are included in the glue used. By purchasing it, it is necessary to carefully examine the ingredients and if it contains:

• ethers (methyl acetate, butyl acetate);
• alcohols;
• natural gas derivatives (propane, hexane and others);
• amines (aniline and other);
• hydrocarbon processing products (gasoline, kerosene, White spirit, etc.)
• ketones (acetone, etc.);
• compounds containing chlorine (dichloroethane, chloroform);
• nitrogen compounds (nitrobenzene, nitromethane);

that buy such glue is not necessary. The compounds included in it have a destroying effect on the structure of polystyrene foam or immediately or over time.

To obtain a qualitative result when sticking foam plastic on the walls, the use of the following materials is recommended:

• compounds based on dry mixtures;
• "Liquid nails";
• mounting foam;
• polyurethan foam.

In some cases, it is possible to combine the designated adhesive compositions.

Before glueing the foam, its surface can be treated with a needle roller to improve adhesion with adhesive mixtures.

We use semi-finished products

Dry glue compositions allow you to glue foam to brick wall Qualitatively and fast enough. Their use has several advantages:

• low cost;
• availability;
• small glue consumption per unit area.

• place of sale (it is desirable to acquire bags that are stored in a closed room);
• the integrity of the package (the surface of the bag should be without through gusts);
• the date of production (buy a mixture made 12 months before the acquisition is not recommended);
• the absence on the bag of traces of falling fluid or surface wetting;
• the mobility of the content when carrying (there should be no feeling of the presence of a large stone in the bag).

• the need to prevent water to prepare;
• spending time on its preparation;
• relatively long-term final fixation on the surface (about 3 days);
• the impossibility of fastening the polystyrene to concrete and metal surfaces.

The finished mixture can be applied both on the foam and wall. Sticker plates from bottom to up.

Old familiar will help

Special difficulty and confusion causes the question: "What glue glue insulation to the metal?" The answer is simple.

Punching of foam plastic on a metal surface is carried out with the help of the construction glue of PVA.

Being an affordable and inexpensive material, it perfectly copes with the task assigned to it. Burlakovin impregnated with glue is fixed on metal. After drying the adhesion, foaming is performed to the wall. Plates are abundantly lubricated PVA.

It is expected to increase glue density (during this time you can smear the next stove). Press the slab for a short time. As a result, get good result By strength fastening.

Fast but dear

Many compounds require retention for some time (sometimes long-lasting) glued plates. What can quickly glue thermal insulator, thereby reducing idle time?

"Liquid nails" are used if necessary, warming up a small wall area from any material. Before gluing a foam to concrete or other material, clean it from extraneous layers and cover the primer layer.

The main advantage of this composition are:

1. versatility of use;
2. installation speed (long-lasting leaf is not required).

There would be a fairly high cost to the lack of price, but for convenience it is necessary to pay. Liquid nails are sold in tubes of 300 ml. Mind from tube with a gun for sealant.

And here you are, my old woman

Installation foam can be glued with polystyrene foam to concrete, brick, stone. To do this, it is enough to apply it around the perimeter and a cross through the center. Attach the slab to the installation location. After installing several rows, fill the gaps between the plates.

Pros of the use of mounting foam:

• reliable fastening of plates on stone building materials;
• simplicity of application.

There are still much more minuses:

• increased degree of expansion after applying (due to uneven expansion, emptiness and surface irregularities can form;
• high foam consumption per meter area;
• the need for long-term fixation of the slab due to long grasp;
• it is possible to destroy the structure of the thermal insulator under the influence of foam components.

If you can lower the flow by using a gun for mounting foam, it is impossible to do anything with other shortcomings. Therefore, it remains to be completed or pick up another adhesive composition, which will stick to the polystyrene foam.

Young, yes strong, flaws he is deprived

If you ask: "What is better to glue a foam insulation?", Then hear in response: "Polyurethane foam glue-foam." It is specifically designed to carry out the fastening of polystyrene foams to vertical surfaces from various materials.

Before sticking the foam to concrete or other material, clean the surface from extraneous sediments, dust and dirt. Strong the wall. With the help of a gun, apply foam to the surface of the plate around the perimeter and to the center of the sheet. Apply the glued sheet to the wall. Hold 5 seconds. You can move to gluing the following.

The use of polyurethane foam glue as fastening agents has huge benefits:

• excellent adhesion of the surface of the foam with any other;
• small foam consumption;
• convenience of work;
• speed mounting;
• high moisture resistance.

In more early periods Construction for insulation of walls was used clay. Before sticking the polystyrene foam, it is not necessary to remove the clay layer. It is enough to cover the surface of clay by any acrylic soil. Now you can glue the insulation.

In the process of use and operation of glue-foam, the minuses are not installed.

You need to know how to glue the foam. Pay attention to the absence of emptiness between the plates glued, withstanding the strict verticality and horizontal position of the sheets.

With the insulation of the walls of the house, it is possible to do only to a mechanical way of fastening foam. But the use of adhesive creates additional closed airspaces under the plates, thereby reducing the heat loss from heated premises.

An interesting experiment with sticking foam:

The extruded polystyrene foam (hereinafter EPPS) is manufactured by mixing the granulated polystyrene with a chemical reagent containing CO 2 and light freuna. The composition is heated and under pressure passes through an extruder. Upon exit from it, forming and cooling is obtained by a finished sheet of material with thermal conductivity indicators - 0.03 W / (m * hail).

For comparison:

• polyfoam - 0.04,
• foam glass - 0.1,
• concrete on gravel - 1.5,
• light concrete - 0.6,
• brickwork 0.7.

This is possible due to 90% of air enclosed in dense closed cell cells.

Characteristics of extruded polystyrene foam

The extruded polystyrene has excellent qualities:

• High strength (withstands load up to 35 t / m 2),
• Resistance to the effects of aggressive environmental factors
• Waterproof,
• Durability - (operation up to 50 years),
• Low vapor permeability, zero capillary
• Environmental friendliness (from expanded polystyrene contains storage containers, disposable dishes and even toys),
• Does not support burning without a source of flame and high temperature

Extruded expanded polystyrene produce different density. A novelty in the market - EPPS of high rigidity -. It contains in its structure of graphite particle, which gives it the opportunity to withstand the load of up to 50 t / m 2. Buy extruded expanded polystyrene foam in Kiev, this species can be from TM TEKHNONICK, PESTROX and other manufacturers.

Polystyrene sticking technology

Bitumen mastic or glue compositions on a cement basis can be used for gluing different grades of EPPS-boards, polyurethane foam. The basis of glue should not include gasoline, ethers, acetone and other organic compounds - they damage it, literally dissolving and leaving holes in the deposition places. In addition, the choice depends on what is subject to insulation: the floor of the building, its walls or ceiling.

In new buildings of small floors, it is recommended to design hollow walls and laying EPPS plates inside them - will save on adhesive and reinforcing elements. Work on the heat insulation device by extruded expanded polystyrene should be carried out in dry weather at ambient temperature not lower than +5 ° C. The exception is only polyurethane foam.

In the case of insulation of the walls or floor of the building, the best choice will be. It is used simultaneously for sticking and for reinforcement. The gluing of the plates from the EPPS is starting to the laying in 1 row. Next, they are fixed with a T-shaped seam dressing, close to each other and to the plates of the next row. It is unacceptable to re-mount, as well as change the position of the plate after 5 minutes after installation. Epps plates are fixed with dowels. For use in brick or concrete Walls Take a dowel with a spacer part of 60 mm, for walls of cellular concrete and a holey brick - 90 mm. Quantity on the sheet 4-6 pcs., At the corners of the building up to 8 pcs. The reinforcing mesh is recorded in the applied layer of adhesive, at the joints of the grid's pieces is made of 10 cm. After the first layer is applied to the second layer. The overall thickness of the reinforcement should be at least 3 mm. Corner sections are protected from damage to aluminum corners. The final plaster layer is applied 3 days after reinforcement.

Used glue compositions

The basis of bitumen mastic is a unified bitumen, plasticizers and solvents. With a continuous application, a good waterproofer is resistant to freezing. In the case of work on the warming of the foundation of the building - this is objectively the best choice Adhesive material. But the surface of gluing requires drying, alignment and stern. It is also not allowed outside the foundation of the protruding parts, lumps of dirt, rust, wet and oily spots. Pre-priming improves quality of work. The period of setting the adhesive bitumen mastic is at least 30 minutes, so the backups will be required. Cement-adhesive compositions are used as the reinforcing layer.

It is also possible to glue the EPPS plates using a polyurethane foam, which is applied by an assembly pistol. It has no secondary expansion, the setting period is about 10 minutes, can be used at low (up to -10 ° C) temperatures. 1 The balloon replaces one twenty-five-talogram bag of glue. The foam is applied by a thin layer, retreating 2 cm from each edge of the EPPS plate and cross-diagonally. Minus glue - its flammability and poisonousness.

The main arguments for and against each of the types of gluing plates of extruded polystyrene foam will allow you to choose for yourself the most suitable option. The main thing - in any case there will be a decrease in energy costs on a warmed object, and accordingly, the figures will decrease in the account on the payment of energy carriers.

The extruded expanded polystyrene deservedly discouraged the fame of a very popular thermal insulation material. Polystyrene foam can be used for interior and exterior work. Successfully extruded polystyrene foam is used to insulate the facades of the building, basements, basement rooms, balconies, insulation of rooms from the inside. This foamed material has whole line Advantages, if you compare it with other insulation. It does not absorb moisture, not deformed (not compacted) over time, light and very durable, has a long service life, is not a favorable medium for the life and reproduction of colonies of microorganisms.

For more reliable fastening of polystyrene floor, use two ways at once: planting glue and fastening with dowels.

Preparing to glue polystyolistic

For fastening polystyrene foaming, the method of gluing is used using glue or special mastic, as well as fastening the plates of the foam insulation to the insulated surface of the dowels. The most reliable option is to combine these two ways. In this case, the plane of the extruded insulation is first glued to the surface, and only after that it is fixed with dowels. This means that it will be necessary to work:

• roulette (for measuring);
• drill and hammer (for attaching dowels);
• roller (for pre-primer surface);
• spatulas (including toothed to apply mastic or glue);
• electric mixer (for kneading glue).

Getting started to choose glue, you need to determine what properties this material should be possessed. Glue, which is ideal for gluing extruded polystyrene foam:

• suitable for outdoor work (pay attention to low temperatures);
• quickly settled;
• provides a reliable adhesion of glued surfaces;
• it is convenient for use.

Back to the category

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

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

Choosing glue for expanded polystyrene, make sure that there is not only gasoline in its composition and
acetone, but also of all sorts of esters and other similar substances. Therefore, it is necessary to choose adhesive compositions or mastic based on plasticizers, bitumen, composite mixture.

Folk craftsmen and just experienced builders are successfully used to fix polystyrene foams such as liquid nails, sealant (meant silicone), frost-resistant adhesive for finishing facade works, adhesive compositions for ceiling tile, frost-resistant and waterproof glue mixes for working with tile. The listed glue mixes are perfectly coping with the task. They can be successfully used, especially if they are available (that is, it is not necessary to carry additional financial costs), and an additional fixation of special dowels is planned. But there are intended for working with polystyrene foam glue mixtures. The advice of professionals focus on these compositions.

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

He insulated its dwelling with polystyrene foams you will receive a durable insulating coating, since this material does not rot and the bacteria are not bred.

In the composition of the adhesives are divided into bituminous and cement-polymer. Bituminous mastics
Create a waterproofing layer (due to the content of bitumen as part of mastic). But for this, the mastic should be applied to the glued surface without spank. Such formulations are plastic, do not require preliminary thermal exposure before the start of work (due to the presence of plasticizers in the ingredients, the mass retains plasticity and without heating).

Cement-polymer-based compounds are used both for internal and external work. They are equally well suitable for gluing polystyrene foaming to concrete, brick wall, foam concrete, drywall surfaces, and can also be used to fix the specified material on the heated surface (warm floors, for example). Cement-polymer adhesive compositions suggest deep primer surface. When choosing, be careful: different stamps should be selected for exterior and internal work. It is hardly justified using for interior decoration Frost-resistant adhesive.

Intended precisely for gluing extrusion (so also called) polystyrene foam compositions require careful prepressing Connected surfaces (perhaps even shranking in some cases). But the result is a reliable and durable clutch. Especially since such adhesive compositions allow the plates from the extruded polystyrene to the surface of brick, concrete, steel, drywall, wood. And this is not a comprehensive list.
