2.7. Clean the surfaces and cracks on it from dust, dirt, splashes and drips of solution using metal scrapers, a flake, an artificial pumice stone fixed in a clip or a hinged grater (Fig.,). 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 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, 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. 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 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 packaged 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. Solid putty is polished using mechanical grinders IE-2201A using sandpaper mounted on a wooden grater and pumice until a smooth surface is obtained, 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. , cracks in places of putty, visible stripes and stains (GOST 22844-72).

Table 2

	Permissible deviations
	surfaces from the plane	from the vertical or horizontal of the window and door slopes, pilaster, husk, usenkov	curved surfaces from the design position	rods from a straight line (for the entire length of the rod)
Improved coloring	no more than 2 irregularities with a depth or height of up to 2 mm	1 mm per 1 m of height or length, but not more than 4 mm for the entire element	5 mm	2 mm
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 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, with 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 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 must 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 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 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.

5. Detailed information about the device and details of the installation components are given in the “Technical description and operating instructions for the installation for manual electropainting UREG-1”.

III. TECHNOLOGY OF WORK PRODUCTION

1. The technology for painting metal structures using a manual electropainting installation UREG-1 consists of performing organizational and preparatory operations, as well as application operations paint coating.

2. Organizational operations are carried out before the start of painting work. To do this you need:

instruct workers on the rules of work;
check the availability of solvents and paints and varnishes for the entire scope of work. All materials must be from the same batch;
arrange all the tools and equipment necessary for work and repair possible malfunctions within the range of workers;
ensure delivery of materials To workplaces using hand trucks.

3. It is prohibited to allow persons who have not undergone appropriate training and instructions to work on the UREG-1 installation.

4. Before starting work, it is also necessary to prepare the surfaces of metal products for the UREG-1 electropainting installation, prepare primer and paint compositions.

5. Preparing the surface of a metal structure involves removing rust and pockets of corrosion to ensure proper adhesion of the paint layer to the base.

6. Work on preparing the surface of metal products for painting is carried out in the following technological order:

cleaning the surface from dust and dirt;
cleaning the surface from rust;
degreasing surfaces;
grounding of products.

7. Before painting, the surfaces of metal structures must be cleaned of dust, dirt, splashes of solution and other contaminants using scrapers and rags.

8. The surfaces of metal structures must be cleaned of rust using steel brushes or chemically 3-4 hours before painting and degreased.

9. Chemical cleaning of rust and simultaneous degreasing are carried out with washing composition N 1120, which includes (in %): phosphoric acid - 30-35; hydroquinone - 1; butyl alcohol - 5; ethyl (denatured) alcohol. 20; water - 39-44.

10. Work on chemical cleaning of metal surfaces with a washing composition consists of applying it with a rag, brush or roller to the surface to be treated, and after 30 minutes of exposure - cleaning the surface with metal brushes and rinsing with composition N 107.

11. If there are cavities and solid rust on the surface of metal structures, it is cleaned chemically using a composition of three parts hydrochloric acid and one part sulfuric acid, followed by neutralization of the surface with an alkali solution (NaOH) and rinsing with water.

In these cases, degreasing of the surface is carried out using the technology adopted at the enterprises of the Mospromelectroconstruction Production Association.

12. Hardware, subject to electropainting, must be grounded by a device with a resistance of at least 100 Ohms.

13. It is prohibited to apply paints and varnishes to the surfaces of uncleaned and ungrounded metal products and structures.

14. Preparation of paints and varnishes for use in electropainting consists of bringing the primer and paint compositions to the required viscosity, checking their electrostatic properties (volume specific resistance, dielectric constant, etc.).

Clean surfaces from dust and dirt with a rag; from rust - with a wire brush or chemicals, applying them to the surface with a rag, brush or roller and then removing them. After removing the rust, wipe the surface completely with a rag.

11. The preparation of working paint compositions is carried out by painters M1 and M2 in quantities not exceeding the shift requirement. In this case, the primer and paint compositions are diluted to the required viscosity, which is controlled with a VZ-4 viscometer, then the volumetric resistivity is determined with the PUS-1 device and the dielectric constant with a quality factor meter of type E-4-4; if necessary, they are corrected by introducing them into the composition required quantity emulsifier OP-7. The finished composition is filtered into the paint injection tank through a semi-pack mesh 05.

12. The preparation of the UREG-1 electropainting installation is carried out by painters M1 and M2. Wherein external inspection make sure there is no damage to the installation elements; All the handles on the panel are set to the “Off” position, if necessary, remove the conservation grease from the installation surfaces with a rag soaked in a solvent. Remove the plugs from the fittings intended for connecting the sprayer, connect the sprayer hoses to the fittings according to the inscriptions, and the cable to the excitation unit, connect the installation to the compressed air network and the electrical network, ground the installation and products.

13. Check the operation of the mixer by turning the knob on the top cover of the mixer air motor two turns, and then placing the tap labeled “Stirrer” in the “Open” position.

The frequency of switching on, duration and intensity of operation of the mixer are set depending on the type of paint and varnish material.

If the air pressure in the network is 0.45-0.5 MPa, then for normal operation of the sprayer it is recommended to turn on the stirrer during breaks in the operation of the sprayer.

14. Set the required width of the torch depending on the coloring of the products, for which remove the nozzle from the sprayer and place the diaphragm in one of the positions marked with numbers on it.

15. Open the valve labeled “Air pressure” and set the required spray pressure within 0.45 - 0.6 MPa. Set the movable nut on the sprayer head to a position where the mark at its front end coincides with the mark on the union nut, on the first turn from the last, the marks on the movable nut correspond to the optimal operating mode of the sprayer: at the front end - at a network air pressure of 0.45 MPa, at the rear - at 0.6 MPa.

16. Set the “Generator Power” switch to the “Network” position - the green light comes on and the sprayer is turned on. At the same time, the red light should light up, then, turning the knob " High voltage"on the control panel, set the current to 75 + 100 µA using a microammeter.

17. Set the required paint pressure, but not more than 0.4 MPa, using a tap marked “Paint pressure” and a regulator.

18. Verify the presence of coverage effect by testing a grounded metal cylinder with a diameter of up to 100 mm without turning it. The best coverage effect is achieved by turning the movable nut on the spray head in the area indicated by the marks.

19. When drawing up a work schedule and calculating labor costs, the operation of preparing electrical painting equipment was taken into account twice a shift (at the beginning of the shift and after the lunch break).

When preparing equipment one-time, it is necessary to make adjustments to the table. 5 and 6.

20. Technological operations for applying primer and paint layers on the surfaces of metal structures using the UREG-1 installation are performed by painter M2; first, he checks the position of the “Paint Supply” and “Paint Pressure” taps on the installation (they must be open), then takes the sprayer into right hand, holding it with the left, and pressing the trigger creates a torch of paint, directing it at the product being painted.

21. When applying the primer and paint layers, the spray gun must be kept at a distance of 250-350 mm from the surface to be painted, since as this distance increases, the loss of paint and varnish material increases.

22. At the end of each shift or at the end of painting work, the M2 painter pours paint from the paint injection tank and pours 3/4 liter of solvent into it, connects the hoses and closes the tank with a lid. Sets the “Paint Supply” and “Paint Pressure” taps to the “Open” position, opens the sprayer and, pouring the solvent into an arbitrary container, rinses the paint supply system until traces of paint disappear. Then wipe the surface of the sprayer with a rag soaked in solvent.

23. When painting metal structures located above 3.5 m from the floor or ceiling, work must be carried out from mobile scaffolds.

24. When calculating the time norm for painting metal surfaces, the operation of the installation from the ground was taken into account; when working from scaffolding, the time norm and prices for priming and painting in table. 5 and 6 must be multiplied by a factor of 1.25 in accordance with EniR, Sat. 8, section III.

N wallpaper cutting

Roll out the wallpaper face up on the table.

Cut the wallpaper to the required length

The second canvas is cut off, combining rapport along the edges of the canvases following each other.

Fold the sheets of wallpaper one after another or number them on the back side so that you don’t have to adjust the pattern on the wall.

Wallpaper sheets are cut to the required length, taking into account that the margin on top should be 6 cm, and on the bottom -4 cm.

R marking the wall surface

You need to make a mark under the ceiling with a pencil, then attach a plumb line to it and make several marks along its entire length.

After this, connect all the marks using a ruler and draw a vertical line from the ceiling to the floor.

P preparing wallpaper glue

Slowly pour 1 package of glue into gradually stirred water and allow it to swell. After which it is mixed again and used for wallpapering.

Prepare glue strictly according to the instructions indicated on the package.

N applying glue to the wall surface

The diluted glue is applied with a roller or brush directly to the wall to the width of 1-2 canvases.

It should be applied quite thickly, covering every centimeter of the wall when applying.

P gluing the first sheet

Glue the top of the wallpaper;

Align the left edge of the canvas with the line drawn with a pencil all the way to the floor.

Smooth the aligned and glued left edge of the canvas with a brush or roller so that it sticks well to the wall.

Press the wallpaper from above at the ceiling line across the entire width of the canvas, using a brush and following the contour of the angle between the ceiling and the wall.

Cut off excess wallpaper, if any.

Make sure that no wrinkles or bubbles form on the surface.

N gluing the following sheets of wallpaper end-to-end

Lightly glue the new strip of wallpaper to the wall about 5 mm from the previous one.

Move it to the one already pasted, pressing the wallpaper with your palms, simultaneously matching the pattern and moving the edges of the canvases end to end.

Move the edge of the next sheet tightly to the edge of the one already pasted and press carefully.

The surface should be free of wrinkles and bubbles. In order for the pattern on the canvases to completely match, you need to align each panel relative to the previous one.
