Gypsum-perlite plaster for manual application GS-77 for leveling walls and ceilings manually applying
Gypsum-perlite plaster is used in finishing works for manual plastering and leveling of walls and ceilings with any type of surface (concrete, gypsum, stone, brick, cellular-concrete) as well as for the preparation of grounds for painting, wallpaper, facing work inside rooms with normal humidity in residential, administrative and industrial buildings. Gypsum plaster allows you to get a smooth surface that does not require putty before the subsequent work. Has a short drying period. It does not form cracks and does not fade, even with a thick layer. Creates bases with improved heat and sound insulation properties for the most comfortable living conditions. In the rooms a favorable microclimate is formed.
Gypsum-perlite plaster – is a method of leveling walls, with the help of screed strips, which is the only effective alternative to gypsum boards. The main advantage – saving the volume of the internal space, as well as ease of repair and maintenance for long-term operation (gypsum cardboard systems should be dismantled). It is possible to apply plaster in the usual way, but the most qualitative result is obtained when performing work using screed strip.
PREPARATION OF THE SURFACE
The surface must be dry and firm, free of dust, oils, dirt and other contaminants of organic origin. To improve the adhesion of the solution to the substrate; for binding of dust residues; for highly absorbent and cementitious substrates – mandatory priming with “ARTISAN No. 7” deep penetration primer is required.
PREPARATION OF THE MORTAR
The dry plaster mixture is mixed with clean water until it is uniform. The mixture is poured into the water. The solution is held for 5-10 minutes, then mixed again. After that, the mixture is ready for use.
PERFORMANCE OF WORK
Plastering is carried out according to predetermined screed strips. The plaster solution is applied to the surface in one layer and leveled. The optimum layer thickness is 10 mm (the minimum is 5 mm, the maximum is 30 mm). After the beginning of setting, the surface is treated with a wide spatula, and after 15-20 minutes rubbed with a sponge grater, moistened with water and smooth with a metal spatula, obtaining an absolutely smooth surface. Plastering in two layers is allowed. For this, it is necessary to apply a notch on the first layer that has not yet hardened, and then apply the second on the dried surface of the first layer.
