DRAWING WALLS AND CEILINGS
First, the surface of the wall or ceiling must be cleaned of dirt, get rid of the remnants of the background and the old paint. If the walls are under the influence of mold, they must be eliminated. There are special chemicals to facilitate these preliminary works.
Building standards define three types of colors for quality: simple, improved and high-quality, and a list of technological procedures that need to be done so that the corresponding color meets the sanitary, technical or aesthetic requirements.

Until the beginning of the painting completion, all prefabricated and general construction works for the construction of walls, ceilings, partitions and roofs must be completed; wet brick walls and joints of floor panels, partitions, as well as crossing points for sanitary water pipes; built-in doors and mezzanines and inserted closets; heating, plumbing and sewage systems are installed and tested on the ground; installed electrical equipment and appliances; purified residue and material residues.

The professional module's work program was developed on the basis of a federal state education standard for vocational vocational education (hereinafter text: non-governmental organizations) 270802.08 Master's degree in dry construction.
Painting works. Lining and painting of walls, ceilings.
To improve adhesion, each layer should be treated with a coating. For hygroscopic surfaces, "breathable" is recommended - ready to use white polymer emulsion. Depending on the degree of absorption of the surface - from 0.07 to 0.1 kg / m2. Work is carried out at a temperature of +5 to +25 ° C, apply the solution with a brush or roller. The drying time of one layer is about 3 hours. The difference between the final drying of the base layer and the subsequent application of the whale should be minimal - this will help prevent the dust from leaking to the surface.
