Varieties of glue for expanded polystyrene
The release form and characteristics of glue for expanded polystyrene can vary significantly. Manufacturers offer different types, each with its own advantages and disadvantages. We invite you to get acquainted with the available options and their distinctive features.

Dry mixes
Dry mixes are in demand when performing interior and exterior work. They are prepared immediately before use in accordance with the manufacturer's recommendation for a specific composition.
Attention! Failure to comply with the ratio of dry glue and water indicated on the package will significantly reduce the characteristics of the finished composition and worsen the fixation of the glued elements.

The main advantages of dry mixes include:
Availability. Such an adhesive for expanded polystyrene is relatively inexpensive. When properly prepared, its performance characteristics are not inferior to ready-made compositions.
Versatility. Most dry mixes can be used for indoor and outdoor use. Such an adhesive for expanded polystyrene has good adhesion to various substrates. Some are not suitable for concrete and metal, which should be considered when choosing a suitable mixture.
High strength properties. All elements are fixed firmly enough. Subject to the technology of performing work, they will be held for at least 30-50 years;
Low consumption. Each square will require an average of about 6 kg of glue.

Among the shortcomings, it is worth noting the need for self-preparation of the solution in strict observance of the proportions established by the manufacturer. The possibility of fixing with dowels - only a day after applying the composition.
Advice! When deciding to purchase dry polystyrene foam glue, check its expiration date.
A high-quality composition retains its characteristics throughout the year when stored in dry and closed rooms. It is not worth purchasing a mixture that has been stored outdoors.

Polyurethane foam
Such glue for polyurethane foam appeared relatively recently, but is very popular. Available in cylinders. Suitable for professional use and work at home.
The features of polyurethane foam include:
ease of application. For work, an assembly gun is required;
versatility. Allows gluing polyurethane foam to various substrates and gluing products from polyurethane foam to each other;
high strength of the formed joint;
availability. This is a budget option used when performing interior and exterior work;
fast drying;
economical consumption due to the fact that you can refuse to form a continuous layer. For a strong adhesion of the expanded polystyrene board to the base, it is enough to apply glue around the perimeter of the board to be glued and at several points in the middle;
resistance to atmospheric precipitation;
optimal viscosity. The composition does not spread over the surface at the time of application;
frost resistance;
the ability to use immediately after purchase.

Bituminous glue
For the manufacture of bituminous glue, a special light solvent is used, which is not capable of having a negative effect on expanded polystyrene. A certain amount of bitumen and plasticizer is added to it. The glue is completely ready to use. Sold in small buckets.
Before applying the glue, the base is thoroughly dried, sanded and primed. The surface should be free of dust, dirt, rust or other stains that can reduce the adhesion strength of the adhesive to the substrate. Not afraid of the effects of gasoline, oil, acid. Retains properties under the rays of the sun. Provides additional protection against moisture.

Liquid Nails
They are used quite often due to their availability. However, the formed joint has low strength characteristics. As a consequence, the joint formed is not durable. To increase the strength of the connection with the base, dowels are used. In this case, it is possible to achieve high-quality work performance. Liquid nails are also used to fill voids in the wall.

Other
Cement-polymer glue can be used for interior and exterior work. The introduction of a certain amount of polymers increases the elasticity of the adhesive composition. When working outside the building, polystyrene foam can be glued to the bases of bricks, cinder blocks, concrete. The composition is sold as a dry mix, which is prepared immediately before use. The solution is not afraid of exposure to moisture, low temperatures.
For gluing polystyrene foam, hot-melt glue can be used, the basis of which is polyamide, ethylene vinyl acetate, which turn into a liquid state during heating. After cooling, they become hard.

Adhesive for expanded polystyrene: we make the right choice, studying the types for external and internal work
So that during the operation of expanded polystyrene there are no difficulties and the element is securely fixed, it is worthwhile to take a responsible approach to the choice of a suitable composition. Manufacturers offer formulations for indoor and outdoor use. We invite you to find out how to make the right choice.
For outdoor work
When performing outdoor work, polystyrene foam glue should be used that can withstand the adverse effects of atmospheric precipitation. The most commonly used is bituminous. The solvent included in its composition is not capable of harming expanded polystyrene plates. It is already completely ready for use. In the process of performing the work, bituminous glue is applied to the thermal insulation boards and the base.
Cement glue can also be a good choice if the house is built of brick, concrete or cinder blocks. It is used when installation of ceiling tiles. Sold dry.

Unis Teplomontazh PPS
For interior work
If you plan to install polystyrene foam boards, you should choose glue:
with a high level of adhesion;
free of toxic substances;
withstanding significant temperature fluctuations;
allowing quick installation with a minimum amount of smudges.
If the humidity in the room is low and there are no significant temperature fluctuations, PVA glue can be used. For rooms with a high level of humidity, it is better to use a rubber-based compound that has good adhesion to any type of substrate. When working with decorative elements made of polystyrene foam, it is worth using white water-soluble compounds. They will allow you to hide the seams between the sheets.

We glue polystyrene foam correctly: an algorithm of actions
In order to securely fix polystyrene foam on the surface of the walls, it is worth adhering to the following algorithm of actions:
An adhesive composition is applied to the expanded polystyrene plate along the perimeter. A solid line is formed at a distance of 2 cm from the edge. The adhesive is applied diagonally across the element.
The expanded polystyrene plate adheres to the base. Within 20 minutes, the position of the elements can be adjusted. The gap between adjacent EPS boards should be 20 mm. They must be in the same plane.
20 minutes after fixing the expanded polystyrene plates with glue, they are fastened using special expansion dowels.
