High-quality finishing should be provided for in all premises, except for technical premises. For painting, apply a water-soluble, waterproof, resistant to repeated wet cleaning and treatment with disinfectant solutions, an acrylic polymer-based paint. In the premises of technical support, plaster should be carried out on a metal mesh of 01,6 mm wire with a cell of 20x20mm. In rooms oriented to the south, provide for the decoration of neutral and cold tones; to the north and east - warm tones. Sections of walls and partitions in the places of installation of sanitary appliances should be lined with ceramic tiles in accordance with GOST 6141-91 to a height of 1,5 m and a width of 1 m. Plaster all air ducts on a metal mesh. To improve the adhesion of the paint layer, the entire surface of the tongue-and-groove plates should be treated with a Knauf-Tifengrund™ primer, which is applied with a roller or brush.
