Fat spots are washed with a 2% hydrochloric acid solution 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%.

A soapy 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. When the jelly is dissolved in water, a homogeneous, precipitation-free liquid primer should be formed. Jelly is used for 10 days in summer and 20 days in winter conditions... To prepare the primer, one weight part of the jelly is cut, filled with two parts of heated water. Then the composition is stirred until the jelly is completely dissolved, add 3 parts cold water and mix thoroughly again. Before use, the primer is filtered through a sieve with 625 holes / cm 2. The primer should be uniform, without traces of delamination and undissolved soap bars. Apply a primer mechanized way using an electrospray gun. To obtain a uniform layer of primer, the fishing rod is moved along the surface at a distance of 0.75 m from it, while simultaneously making smooth circular movements in a spiral. For small volumes of work, the primer is applied using brushes.

The size of the grip is determined taking into account the development achieved by the link; each seizure must consist of a whole number of apartments in residential buildings, a whole number of premises in administrative, school and cultural and social buildings. In industrial buildings, the seizure should consist of a small number of spans.

2.21. Work on painting surfaces with adhesives is carried out by specialized units of two people each: a painter of the 3rd category and a painter of the 2nd category.

First, both members of the link prepare the surfaces for painting, that is, they smooth or polish the surfaces and embroider the cracks. After creating the necessary front of work, the 3rd grade painter proceeds to priming the surfaces with an electric spray gun.

After drying the primed surface, the 2nd grade painter makes a partial grease individual places, then both members of the link perform filling and polishing of the surfaces. The second priming of surfaces and their subsequent painting with an electric spray gun is performed by both members of the link: a painter of the 3rd category applies the compositions to the surface, a painter of the 2nd category fills the electric spray gun with an adhesive composition.

2.22. It is recommended to carry out painting work by the flow-dismembered and flow-complex method. In the first case, the brigade is divided into links that are specialized in performing a group of operations - surface preparation, putty, water-chalk painting of ceilings and walls, etc. Specialized units perform the same types of work at each grip. Such links create a continuous flow at the facility, moving one after the other as work is done. The approximate composition of the specialized teams: painter of the 2nd grade - 1 person, painter of the 3rd grade - 1 person, painter of the 4th grade - 1 person. In the second case (with the flow-complex method), the entire building or its sections are prepared for painting work. Each link performs all painting operations on the grip and consists of three painters of 2, 3 and 4 categories. All links are working on seizures in parallel.

At the same time, the primer and paint compositions are diluted to the desired viscosity, which is controlled by a VZ-4 viscometer, then the volume resistivity is determined by the PUS-1 device and the dielectric constant is determined with a Q-factor meter of the E-4-4 type, if necessary, they are corrected by introducing into the composition the required amount emulsifier OP-7. The finished composition is filtered into an injection tank through a semi-compact mesh 05.

12. The preparation of the UREG-1 electric paint unit is performed by painters M1 and M2. At the same time, by external examination, they are convinced that there is no damage to the installation elements; all handles on the panel are set to the "Off" position, if necessary, remove the preservative grease from the installation surfaces with a cloth soaked in solvent. Remove the plugs from the nozzles 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 unit to the compressed air network and the power supply network, ground the unit and products.

13. Check the operation of the agitator by turning the knob on the top cover of the agitator pneumatic motor by two turns, and then put the tap with the inscription "Agitator" in the "Open" position.

The frequency of switching on, the duration and intensity of the stirrer 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 work it is recommended to turn on the agitator during breaks in the operation of the sprayer.

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

15. Open the tap with the inscription "Air pressure", set the required spray pressure in the range of 0.45 - 0.6 MPa. Set the movable nut on the spray head to the position when the mark at its front end coincides with the mark on the union nut, on the first revolution from the last, the marks on the movable nut correspond to optimal regime sprayer operation: at the front end - at an air pressure in the network of 0.45 MPa, at the rear - at 0.6 MPa.

16. Set the "Generator Power" switch to the "Mains" position - the green light comes on, turn on the sprayer. In this case, a red light should light up, then, turning the "High voltage" knob on the control panel, set the current 75 + 100 μA by the microammeter.

17. Set the required paint pressure, but not more than 0.4 MPa, using a valve with the inscription "Paint pressure" and a regulator.

18. Confirm the presence of the affect of coverage 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 forefathers of the marked area.

19. When drawing up a work schedule and calculating labor costs, it was taken into account the execution of the operation for the preparation of electro-paint equipment twice per shift (at the beginning of the shift and after the lunch break).

With a one-time preparation of the equipment, it is necessary to make adjustments to the table. 5 and 6.

20. Technological operations for applying primer and paint layers on the surface 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" valves on the installation (they must be open), then takes the spray gun in his right hand, holding it with his left, and by pressing the trigger creates a torch of paint, directing it to the product to be painted.

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

22. At the end of each shift or at the end of painting work, painter M2 pours paint from the spray tank and pours 3/4 l of solvent into it, connects the sleeves and closes the tank with a lid. Sets the "Paint supply" and "Paint pressure" taps to the "Open" position, opens the spray gun and, pouring the solvent into an arbitrary container, flushes the paint supply system until the traces of paint disappear. Then he wipes the surface of the sprayer with a cloth soaked in solvent.

23. When painting metal structures located higher than 3.5 m from the floor or ceiling mark, work must be performed from a mobile platform.

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

Preparation of lime paint composition

Capacity, construction mixer

Lime dough is diluted in 6 liters of water, table salt dissolved in 0.5 liters of water is added, and everything is mixed. Then add water to 10 l and get a white color. If a color tint is needed, then a pigment soaked in water is added to the white composition and mixed thoroughly. For staining, various coloring compositions or colors are prepared.

Surface priming

Brush

The surfaces are cleaned, moistened with water and primed. When preparing a lime primer with table salt, the lime dough is diluted in 5 liters of water and table salt dissolved in boiling water is added to this solution. With constant stirring, pour in water up to 10 liters. Lime dough consumption - 2.5 kg, salt - 0.1 kg.

Surface painting

Brush

Lime paint is used both outside and inside buildings to cover porous and plastered lime mortars surfaces, brick walls as well as for painting damp and cold rooms. Apply the composition with a brush. When painting with a brush, put two or three thin layers on the still wet previous layer.

It must be remembered that lime paint is usually applied with horizontal movements, and shading is done vertically.

Safety precautions.

Before starting work, you must undergo a safety briefing, put on overalls, inspect workplace, check the correct placement of materials and the serviceability of the tool, inventory, fixtures. The tool must be used for its intended purpose. When painting surfaces with lime compounds, the painter should use individual protection- goggles, cotton or rubber gloves, respirator. All operations of the technological process must be carried out in compliance with the technical safety rules. When working, it is very important to choose the correct working position. This not only reduces fatigue, but also largely protects against injury of all kinds. After finishing work, clean the tool, clean the workplace, carry out personal hygiene.

SNiP 3.03.01-87. Bearing and enclosing structures;

SNiP 3.04.01-87 Insulating and finishing coatings.

2. TECHNOLOGY AND ORGANIZATION OF WORK PERFORMANCE

2.1. In accordance with SNiP 12-01-2004 "Organization of construction", before the start of preparation of plastered or concrete interior walls for painting, the subcontractor must, according to an act, accept the erected internal walls and partitions from the general contractor.

2.2. Before starting work on the preparation of internal walls for painting, organizational and preparatory measures must be performed in accordance with SNiP 12-01-2004 "Organization of construction", including the following:

Free the workplace from debris and foreign objects;

Submit materials, devices and tools to the workplace in the amount necessary for the work;

Arrange the lighting of the working area;

Fencing staircase openings and along the perimeter of the building;

Appoint a person responsible for the quality and safe performance of work;

Instruct the members of the team on safety measures and familiarize them with the working flow chart for finishing the surfaces of the internal walls;

7.6. The person responsible for the safe performance of work is obliged to:

To acquaint workers with a working flow chart against signature;

Monitor the good condition of tools, mechanisms and devices;

To instruct on special precautions required when operating scaffolding and scaffolds, supplying materials to workplaces;

Explain to employees their responsibilities and the sequence of operations.

7.7. When performing finishing work, it is necessary to provide for measures to prevent the exposure of workers to the following hazardous and harmful production factors:

Increased dust and gas content in the air in the working area;

Sharp edges, burrs and roughness on the surfaces of finishing materials and structures;

Insufficient illumination of the working area.

7.8. Materials and products are stored taking into account their mass and the ability to deform under the influence of the mass of the overlying load. They are stacked in such a way that they do not interfere with the passage of workers. A working aisle with a width of at least 60 cm is left between the stacks of materials and the wall. The gap between the wall and the working platform of the scaffold should not exceed 5 cm. To lift workers, ladders with handrails are installed on the scaffold.

7.9. The condition of all scaffold structures is systematically monitored. Every day after the end of work, the scaffolds are cleared of debris.

The admission of workers to the execution of finishing work from the scaffold is allowed after inspection by the foreman or foreman together with the foreman of serviceability load-bearing structures scaffolds and fences.

7.10. Only specially trained workers are allowed to work with electrified tools.

7.11. When dry cleaning the surface and other work involving the release of dust and gases, it is necessary to use respirators and goggles.

Workers engaged in finishing work must be provided with the following individual and collective protective equipment:

Special footwear and overalls;

Rubber gloves;

Cotton gloves;

For eye protection - open or closed glasses;

For respiratory protection - anti-dust respirators RU-60MA, RPG-67A, ShB-1, "Lepestok".

7.12. Before starting work, the machines and mechanisms used for preparing and mixing the solution are checked at idle speed. The bodies of all mechanisms must be grounded, the conductive wires are reliably insulated, and the starting switches are closed. When working with mechanisms and equipment, it is necessary to comply with the safety requirements specified in the operating instructions for this equipment.

Persons who have undergone special training and passed labor safety exams are allowed to operate the mechanisms.

7.13. When performing finishing work, inventory scaffolds, step-ladders should be used. It is not allowed to use ladders, random means of paving, and to carry out work in non-fenced workplaces located at a height of more than 1.3 m above the ceiling.

7.14. Using finishing materials the formation of a small amount of solid and liquid waste is possible, which is collected in special containers and sent for destruction. In the same way, the product is disposed of after the expiration of the guaranteed storage period. It is necessary to strictly observe the whole range of measures for environmental protection.
