Grease stains are washed with a 2% solution of hydrochloric acid using a brush; efflorescence on the surface is swept away with brushes, the cleaned areas are washed and the surface is dried to a moisture content of no more than 8%. The cracks are opened with a plaster knife or a metal spatula to a depth of 2 mm.

Surface priming

Soap primer at a construction site is prepared from a concentrated base (jelly) produced by the Stroydetal plant of the Mosotdelprom trust in the form of briquettes weighing 1 kg. The jelly is used for 10 days in summer and 20 days in winter. To prepare the primer, the weight portion of the jelly is poured in two parts. hot water (t= 80 °C). Then the composition is stirred until the jelly is completely dissolved, add 3 parts cold water and mix thoroughly again. Before use, filter the primer through a sieve with 625 holes/cm2. The primer must be uniform, without traces of delamination, undissolved pieces of soap, and also without grains of sand and other debris. Apply primer mechanized way using an electric spray gun or spray gun. To obtain a uniform layer of primer, the fishing rod is moved along the surface at a distance of 0.75 m from the seam, simultaneously making smooth circular movements in a spiral. The second and third priming is carried out with a painting composition diluted with water to a viscosity of 40 - 43 seconds according to VZ-4, applied using a roller.

drying oil, kg - 1

pigment for tint, kg - 0.05 - 0.1

solvent (turpentine, gasoline, etc.), kg - 0.05 - 0.1

With thorough mixing, pigment is introduced into the drying oil and the mixture is passed through a sieve with a mesh of 918 holes/cm 2. Before use, add solvent to the composition until it reaches a working consistency.

The second and, if necessary, third priming is done with a color that matches the color of the final painting, diluted with drying oil or emulsion to a more liquid consistency.

The primer is applied to the surface in a thin, even, continuous layer, without gaps, carefully shaded. The primed surface should have an even color without isolated glossy or matte areas.

2.10. Embroidered cracks, cavities and other irregularities are filled with putty using a steel or wooden spatula. After the greased areas have dried, they are polished using pumice inserted into the holder or sanding paper attached to the holder.

2.11. The putty used for filling cracks, cavities and leveling surfaces must be a homogeneous, non-separating mass, have the property of strong adhesion to the surface, and can be easily leveled on the surface being treated. The putty is prepared centrally at the Stroydetal plant and delivered to the construction site packed in plastic bags weighing 15 kg. At the work site, the putty is passed through for grinding in a paint grinder SO-116 (if necessary).

The first continuous putty should be carried out with a composition that differs in color from the first primer layer and the partial putty layer.

The putty is applied in a uniform, continuous layer 2 - 3 mm thick “on a tear” with a metal or plastic spatula, followed by smoothing and removing excess putty until gaps in the lower layer appear from underneath it. The putty should only fill the depressions. The second and subsequent solid putties are made with a composition different in color from the first, etc. (rice. , ).

2.12. Grinding of solid putty is carried out using mechanical grinding machines IE-2201A with sandpaper, strengthened on a wooden grater, with pumice until a smooth surface is obtained, followed by dust removal with a vacuum cleaner.

High quality painting	no more than 2 irregularities with a depth or height of up to 1.5 mm	1 mm per 1 m of height or length, but not more than 2 mm for the entire element	3 mm	1.8 mm

Surfaces prepared for painting must be checked anywhere, but in at least three places for unevenness and local defects.

Painting the surfaces of building structures indoors with water-based paints

2.14. Emulsion paints are produced by industry different colors, ready to eat. Before use, mix the paint thoroughly and bring it to a working consistency by adding water. Water-based paints cannot be applied to surfaces previously treated with vitriol.

2.15. For the first coloring, viscosity water-based paint adjusted to 50 - 70 sec, according to VZ-4, and for the second - 70 - 80 sec. The surface is painted with rollers on elongated handles directly from the floor or with brushes. Before this, using a hand brush, they make a layer of the ceilings and baseboards and paint the inner corners.

Painting the surfaces of building structures indoors with oil paints

2.16. Oil paints are a suspension of the corresponding pigment (iron lead, mummy, ocher, etc.) rubbed into drying oil.

Before use, they are brought to a paintable consistency by diluting with natural drying oil in an amount of 30 - 40% of the weight of the thickly grated paint. After diluting with drying oil, the paint is, if necessary, diluted with white spirit in an amount of no more than 5% of the weight of the diluted paint.

If the primer is applied manually, it is prepared according to the recipe specified in paragraph. Drying oil is added to thickly rubbed paint of the same color as the paint composition for subsequent painting.

When applying the primer by air spraying, a VM emulsion (water: oil) is used, prepared centrally at the Stroydetal plant of Mosotdelprom. The emulsion is delivered to the construction site ready for use in cans.

Apply the emulsion using an electric spray gun or spray gun, see paragraph.

2.17. Painting with water-based and oil-based paints is done with rollers or brushes. When painting with a brush, it is immersed in a container with paint to 1/4 of the length of the bristles. First, the paint is applied in bold, slightly receding stripes from one another and shaded in the transverse, and then, finally, in the longitudinal direction.

When painting with a roller, the roller is lowered into the bath and rolled once or twice along an inclined grid, squeezing out excess paint. Then roll the roller over the surface. Painting is done in two or three passes with a roller: the first pass is carried out with vertical movements of the roller; the second - in the horizontal direction, shading the applied layer. With each subsequent pass of the roller, the previous one should be overlapped by 3 - 4 cm (Fig.).

2.18. Fluting is performed with the end of a dry brush without pressing on the flute using reverse movements of the flute until brush marks and streaks are completely removed from the surface (Fig.).

2.19. Trimming (if necessary) is performed with a dry trimming brush, applying light blows to the freshly painted surface (Fig.).

2.20. Painting must be carried out in compliance with SNiP III-4-80 “Safety in Construction” and “Fire Safety Rules for Construction and Installation Work”.

Particular attention should be paid to the following: painting work at height should be carried out from inventory scaffolding, stepladders, universal trestle tables, mobile towers and other inventory devices. When performing work on flights of stairs it is necessary to use special scaffolding (tables) with different lengths support posts, installed on the steps.

The working floor must be horizontal and have guards.

Store painting materials permitted only in places specially designated by the PPR.

When preparing painting compositions using a paint grinder, the following precautions must be taken:

do not allow the electric motor to overheat while the paint grinder is operating;

do not leave the working paint grinder unattended;

Do not allow unauthorized persons who have not undergone special training to operate the paint grinder.

Persons at least 18 years of age who have undergone special training and received a certificate for the right to work with these tools are allowed to work with electrified tools.

When cleaning the surface and sanding, you must use safety glasses. When washing surfaces with a solution of hydrochloric acid workers must use safety glasses, rubber boots and gloves. Dilute the acid by slowly pouring it into water. Paints, drying oils, and solvents should be prepared and stored in separate buildings equipped with ventilation. Containers for adhesives and paints must be stored in a specially designated place outside the premises on a designated area, at least 30 m away from the place of work.

2.21. The painting work front is divided into sections. The size of the units is determined taking into account the output achieved by the unit; each area must consist of a whole number of apartments in residential buildings, a whole number of premises in administrative, school and cultural buildings. IN industrial buildings the capture must consist of an integer number of spans.

2.22. Painting works with oil and water-based compositions are carried out by specialized units of two people each: painters of the 4th and 2nd categories. First, both members of the team prepare the surfaces for painting, that is, they smooth or clean the surfaces and fill out cracks. Then the 4th category painter primes the surfaces with an electric spray gun or roller. After drying the primed surface, the 2nd category painter performs partial lubrication individual places, then both members of the team perform continuous puttying of the surface, then grinding it. The second priming, puttying and subsequent painting of surfaces is carried out by both members of the team.

surface cleaning;
surface smoothing;
bridging cracks;
primer;
partial lubrication;
sanding greased areas;
solid putty;
grinding;
second solid putty;
grinding.

2.7. Clean the surfaces and cracks on it from dust, dirt, splashes and drips of solution using metal scrapers, a flake, artificial pumice fixed in a clip or a hinged grater (Fig. 1, 2). Grease stains are washed with a 2% solution of hydrochloric acid using a brush; efflorescence on the surface is swept away with brushes, the cleaned areas are washed and the surface is dried to a moisture content of no more than 8%. The cracks are opened with a plaster knife or a metal spatula to a depth of 2 mm.

Surface priming

2.8. For painting with water-based compositions, the first priming of the surface is carried out with a soap maker prepared in accordance with TU 400-2-143-77 (notice No. 1 on the extension until 1982) from bone glue, drying oil, laundry soap and water.

Soap primer at a construction site is prepared from a concentrated base (jelly) produced by the Stroydetal plant of the Mosotdelprom trust in the form of briquettes weighing 1 kg. The jelly is used for 10 days in summer and 20 days in winter. To prepare the primer, a weight part of the jelly is poured with two parts of hot water (t = 80 °C). Then the composition is stirred until the jelly is completely dissolved, 3 parts of cold water are added and mixed thoroughly again. Before use, filter the primer through a sieve with 625 holes/cm2. The primer must be uniform, without traces of delamination, undissolved pieces of soap, and also without grains of sand and other debris. The primer composition is applied mechanically using an electric spray gun or spray gun. To obtain a uniform layer of primer, the fishing rod is moved along the surface at a distance of 0.75 m from the seam, simultaneously making smooth circular movements in a spiral. The second and third priming is carried out with a painting composition diluted with water to a viscosity of 40 - 43 sec. according to VZ-4, applied using a roller.

2.9. Before painting oil compositions perform drying of surfaces with the following composition:

drying oil, kg - 1;
pigment for subcolor, kg - 0.05 - 0.1;
solvent (turpentine, gasoline, etc.), kg - 0.05 - 0.1;

The second and, if necessary, third priming is done with a color that matches the color of the final painting, diluted with drying oil or emulsion to a more liquid consistency.

The primer is applied to the surface in a thin, even, continuous layer, without gaps, carefully shaded. The primed surface should have an even color without isolated glossy or matte areas.

The first continuous putty should be carried out with a composition that differs in color from the first primer layer and the partial putty layer.

2.12. Solid putty is polished using mechanical grinders IE-2201A using sandpaper mounted on a wooden grater and pumice until smooth surface followed by dust removal with a vacuum cleaner.

2.13. Surfaces prepared for painting should not be bleached, and also should not have deviations exceeding those given in the table. 2, cracks in places of putty, visible stripes and stains (GOST 22844-72).

Surfaces prepared for painting must be checked anywhere, but in at least three places for unevenness and local defects.

Painting the surfaces of building structures indoors with water-based paints

2.14. Emulsion paints are produced by the industry in different colors, ready for use. Before use, mix the paint thoroughly and bring it to a working consistency by adding water. Water-based paints cannot be applied to surfaces previously treated with vitriol.

2.15. For the first painting, the viscosity of the water-based paint is adjusted to 50 - 70 sec, according to VZ-4, and for the second - 70 - 80 sec. The surface is painted with rollers on elongated handles directly from the floor or with brushes. Before this, using a hand brush, they make a layer of the ceilings and baseboards and paint the inner corners.

Painting the surfaces of building structures indoors with oil paints

2.16. Oil paints are a suspension of the corresponding pigment (iron lead, mummy, ocher, etc.) rubbed into drying oil.

If the primer is applied manually, it is prepared according to the recipe specified in paragraph 2.9. Drying oil is added to thickly rubbed paint of the same color as the paint composition for subsequent painting.

Apply the emulsion using an electric spray gun or spray gun, see paragraph 2.8.

2.18. Fluting is performed with the end of a dry brush without pressing on the flute using reciprocal movements of the flute until brush marks and streaks are completely removed from the surface (Fig. 6).

2.19. Trimming (if necessary) is performed with a dry trimming brush, applying light blows to the freshly painted surface (Fig. 7).

2.20. Painting must be carried out in compliance with SNiP III-4-80 “Safety in Construction” and “Rules fire safety during construction and installation works."

Particular attention should be paid to the following: painting work at height should be carried out from inventory scaffolding, stepladders, universal trestle tables, mobile towers and other inventory devices. When carrying out work on flights of stairs, it is necessary to use special scaffolding (tables) with different lengths of support posts installed on the steps.

The working floor must be horizontal and have guards.

Storage of painting materials is permitted only in places specially designated by the PPR.

When preparing painting compositions using a paint grinder, the following precautions must be taken:

do not allow the electric motor to overheat while the paint grinder is operating;
do not leave the working paint grinder unattended;
Do not allow unauthorized persons who have not undergone special training to operate the paint grinder.

Persons at least 18 years of age who have undergone special training and received a certificate for the right to work with these tools are allowed to work with electrified tools.

When cleaning the surface and sanding, you must use safety glasses. When washing surfaces with hydrochloric acid solution, workers should wear safety glasses, rubber boots and gloves. Dilute the acid by slowly pouring it into water. Paints, drying oils, and solvents should be prepared and stored in separate buildings equipped with ventilation. Containers for adhesives and paints must be stored in a specially designated place outside the premises on a designated area, at least 30 m away from the place of work.

2.21. The painting work front is divided into sections. The size of the occupation is determined taking into account the output achieved by the unit; each occupation must consist of an integer number of apartments in residential buildings, an integer number of premises in administrative, school and cultural buildings. In industrial buildings, the enclosure must consist of a whole number of spans.

2.22. Painting work with oil and water-based compositions is carried out by specialized units of two people each: painters of the 4th and 2nd categories. First, both members of the team prepare the surfaces for painting, that is, they smooth or clean the surfaces and fill out cracks. Then the 4th category painter primes the surfaces with an electric spray gun or roller. After drying the primed surface, the painter of the 2nd category performs partial lubrication of individual places, then both members of the team perform continuous puttying of the surface, then grinding it. The second priming, puttying and subsequent painting of surfaces is carried out by both members of the team.
