Gluing polystyrene foam insulation boards to the prepared substrate should be carried out by means of adhesives. The adhesive is applied around the perimeter insulation boards stripe width from 40 to 50 mm at a distance of about 20 mm from the edge and some bread diameter from 80 to 100 mm – in the middle of the plate. The number of adhesive composition should be such that after pressing plate area of the contact adhesive layer is not less than 40% of the Square plate. With a flat wall surface bonding insulation boards can produce-Xia for the entire plane. In this case the adhesive is applied to the surface of the insulation board with a notched trowel or trowel with teeth the size of 12 mm.
When applying adhesive to the excess must be removed from the edges of the slab to prevent the penetration of the joints in the bonding plates. Method of attaching insulation boards made of accordance with the P3 to the SNIP 03/03/01 and indicated in the draft of the work. Insulation boards are fixed with ligation of vertical joints tightly to one another from the bottom up from the basement to the eaves or the profile of the roof overhang. Plate applied to the ground, pressed down and finish a long trowel so that it was in the same plane as the adjacent slabs. The gaps between the insulation boards laid over a width of 2 mm should be filled foam. The foam should be given deep, so it will not get into the gap between the insulation boards and the wall. The excess foam after curing medium zayut knife. When designing a building insulation angles insulation board glued on the corner with an overlap of not less than the thickness of a plate, and another joined to it.
This should be provided plates bond series. Speakers of the insulation boards should be cut exactly to the different sides of the angle of turn. All joints with protruding structural elements (balcony slabs, roofs and other parts beyond the insulation system) must be filled with sealant. No sooner than 3 days after bonding insulation boards Styrofoam their surface should be treated with a rough sandpaper.
