To protect the walls of aerated concrete, high -quality decoration with special plaster solutions or facing with facing materials is required.

Different facing materials, including facing bricks, are used to facing walls from gas blocks. In the case of wall cladding with facing bricks, a surface putty of walls should be made to seal cracks through which the internal moisture can penetrate the gas sterlet blocks.
The decoration of the gas -wing walls of the building with facing bricks is carried out according to the principle of the ventilated facade, when a gap is left between the facing layer of brick and the wall of the wall. The laying of the facing layer of brick is carried out according to the rules of reinforced masonry. To protect the surface of the wall from gas -sized blocks, a waterproofing of moisture from the walls is carried out. As a waterproofing of walls, a waterproofing polyvinyl chloride film or membrane is used, which is installed on the surface of the wall at the level of the basement of the building.
In the upper part of the building, a ventilation gap is created, through which air circulation is circulating condensing moisture, which is collected on the surface of the waterproofing layer and on the inner surface of the facing wall.
