The coating of metal battens is complete without scratches, and the paint film of wood battens is smooth, clean and beautiful. What is the pattern combination of embossed glass and patterned glass? Uniform colors, smooth and consistent patterns and tight seams? .
1、? Wipe the original base (except the new house and the intact old paint layer) clean. Before scraping ash, check the original base with 2M feet. If the error exceeds 5㎜, use talcum powder and white cement or gypsum powder for leveling, and ask the customer to sign.
2、? Gypsum board base, jointing with gypsum powder, then pasting kraft paper or special bandage, and special screws for gypsum board must be repaired with antirust paint.
3、? The laminated base must be painted with alkyd varnish first, then jointing with wood glue powder or putty, and then pasted with kraft paper or special bandage, without foaming.
4? , finished putty paste, cooked rubber powder and talcum powder must use qualified products.
5? White latex and alkyd varnish should be properly added to putty ash. Putty should be stirred with a big electric drill, with proper viscosity and even gluing.
6、? For the first time, putty can be leveled by1m-1.5m. The perpendicularity and smoothness of the angle of Yin and Yang must be aligned with chalk lines. The last putty should be completely dried before construction.
7、? After the second putty treatment, the wall surface should be smooth, and the flatness should be checked with a 2-meter ruler, with the surface ≤3㎜.
8、? The third time, the putty was partially repaired. Use a 200-watt bulb or 800-iodine tungsten lamp side lighting to check the flatness and patching.
9? When scraping putty, the ash falling on the ground or other places should be as little as possible. If it falls on wooden cabinets and doors, it should be cleaned immediately. Strictly prevent pollution from other types of work. The smoothness of latex paint should be touched by hand, except with a 2-meter ruler. There should be no obvious concave-convex feeling and granular point feeling.
10、? Paint builders should use horse stools and springboard when scraping ash from a height, and it is forbidden to trample on wood. Scaffolding is safe, reliable and easy to use. If the floor or tile has been finished and repainted, the horse stool must be wrapped in cloth before use.
1 1? Use paper tape to protect doors, cabinets and other places bordering latex paint. Clean the floating ash on the wall with a feather duster before painting the primer. When the lines are treated with latex paint, the lines should be sanded and nailed, and the construction can only begin after the joints are trimmed. After completion, the line texture should be clear and well connected.
12、? One coat of primer and two coats of paint for latex paint construction. After brushing the primer, adjust the putty with the primer to make up for it, and then brush the topcoat after polishing. Latex paint, circuit, switch ||| Source | Test | Large panel, and the closing of wood must be tight and smooth, and it is not allowed to brush or pollute the circuit.
13? When painting the top coat, water should be added according to the actual situation and mixed evenly, and the amount of water should not exceed 20% at most. Too dry is prone to brush marks, and too much hiding power is not enough.
14、? If the top coat is painted, it should be painted evenly from top to bottom, first vertically and then horizontally, and finally gently comb the brush marks in the vertical direction. When painting the top coat, there should be no obvious brush marks and flowing phenomenon. Painting construction should be carried out from top to bottom, and the same area should be completed continuously after the flowers fall to the ground.
15、? If it is necessary to pause in the process of painting, the brush or roller should be soaked in paint or clear water in time, and all appliances should be washed with clear water immediately after painting, and dried in the shade for later use. Finally, the topcoat construction should be completed with polyester paint to prevent the latex paint from yellowing.
16、? The second topcoat shall be carried out after the last topcoat is completely dried, with an interval of at least two hours. Latex paint construction room temperature should be above 5 degrees Celsius. At the same time, close the doors and windows to reduce air circulation, and open the window for ventilation after brushing your teeth for 2 hours. Check and make sure there are no train spots, sagging, obvious brush marks and cracks.
17、? When the latex paint is applied, other types of work shall not be constructed to prevent pollution. Pay attention to finished product protection (ground and adjacent finished products). The residual latex paint on other decorative products should be cleaned.
18? After the construction of latex paint, attention should be paid to the protection of finished products, especially the shiny and mercerized latex paint, because it is easy to appear' flower' phenomenon after repainting. If latex paint is sprayed, it must be sprayed once with special spraying equipment, and the second spraying should be carried out after the first coating is dried.
19? When making color latex paint in a large area, a wall or a room should be well constructed, and it can only be constructed after being checked and confirmed by | source | | customers.
20? The switch socket must be wrapped and protected from pollution.
2 1、? There shall be no brush marks, sagging, particles and powder dropping.
