The second stage of insulation of the house with polystyrene slabs is the preparation of polystyrene plates for its sticker on the wall. There are several types of foam for insulation. If the surface of the foam has a very smooth surface, then to improve its sticker the surface of each foam sheet is brought to roughness. Sheet roughness can be made with a needle roller or ordinary knife.

For stickers of foam on the wall on the sheets of foam, the glue solution with bumps is applied to the entire foam sheet, and the sheet is pressed against the wall with a sliding way, for crushing the bumps of the adhesive solution. Foam installation begins with the lower row. It is also necessary to take into account the fact that the glued foam sheets before the glue harden can move and slide down. To prevent sliding on the wall, a support rail is installed on which the first row of foam is based on. The glue solution can be applied to both the wall and on the foam. It depends on the evenness of the wall.
If the wall has irregularities within 1 cm, then the adhesive solution can be applied to the wall under the comb. But it is best to put large bumps on the stove and the sliding method to crush them for gluing. To glue polystyrene foams, an adhesive solution with high adhesive qualities is used. If there are irregularities and changes on the wall, which go beyond the limit of one centimeter, then the glue should be applied to the wall, laying a little more adhesive solution in the sites.
