1. Coatings: latex paints specified in the design should have product qualification certificates and instructions for use.
2. Materials for putty: talcum powder or white powder, gypsum powder, carboxymethyl cellulose, polyvinyl acetate emulsion.
3. Pigments: various organic or inorganic pigments.
Generally, there should be high stools, scaffolding boards, small shovels, wipes, knives, rubber scrapers, steel scrapers, putty pallets, brooms, small buckets, large buckets, pens, brushes, etc.
1. The wall surface should be basically dry, and the moisture content of the base layer should not exceed 10%.
2. After the plastering work is completed, the pipes passing through the wall, openings, yin and yang corners, etc. should be plastered, leveled and repaired in advance, and fully dried.
3. The installation of door and window glass is completed, the ground construction of wet work is completed, and the pressure test of pipeline equipment is completed.
4. It is required to be carried out under heating conditions in winter, and the ambient temperature is not lower than 5°C.
1. Process flow:
Clean the wall → repair the wall → scrape the putty → brush the first coat of latex paint → brush the second coat of latex paint → brush the third coat of latex paint
2. Clean the wall surface: Clean up the peeling and loose parts of the wall surface, and fill it with cement mortar, shovel off the residual ash, and then sweep the wall surface.
3. Repair the wall surface: Level the bumps and potholes on the wall with plaster, after drying, grind off the protrusions with sandpaper, and sweep away the floating dust.
4. Putty scraping: The number of putty scraping can be determined by the flatness of the wall. Generally, it is three times. The weight ratio of putty is latex: talcum powder (or white powder): 2% carboxymethyl cellulose = 1:5:3.5 . Polyvinyl acetate emulsion for kitchen, toilet and bathroom: cement: water = 1:5:1 water-resistant putty. For the first time, use a rubber scraper to scrape horizontally. One scraper is followed by another scraper. The joints must not be left behind. After drying, sand paper, polish the floating putty and spots, and then clean the wall. For the second pass, use a rubber scraper to scrape vertically. The materials and methods used are the same as the first putty. After drying, sandpaper and clean it. For the third time, use a rubber scraper to find the putty or use a steel scraper to scrape the putty all over, scrape the wall surface smooth, and after drying, use fine sandpaper to smooth it, and the putty must not be missed or worn through.
5. Brush the latex paint for the first time: the painting sequence is to paint the roof first and then the wall, and the wall is first up and then down. Clean the wall first, and wipe off the dust on the wall with a cloth. Latex paint is painted with a pen. When using a new pen, remove the floating hair and loose hair on the pen. The latex paint should be stirred evenly before use, and diluted with water appropriately to prevent the first coat of paint from being scratched. After drying, refill the putty, then polish it with sandpaper after drying, and clean it up.
6. Brush the latex paint for the second time: the operation requirements are the same as the first time. Stir fully before use. If it is not very thick, it is not suitable to add water to prevent the bottom from showing through. After the paint film is dry, use fine sandpaper to polish off the small pimples and brush hairs on the wall, and clean it after smoothing.
7. Brush the latex paint for the third time: the method is the same as the second time for latex paint. Since the latex paint film dries quickly, it should be operated continuously and quickly. When painting, start from one end and gradually brush to the other end. The brush should be connected up and down, and the last row of pens should be followed by the previous row of pens to avoid joints after drying.
1. Guaranteed items: The variety and color of materials should meet the requirements of the design and selected samples. Peeling, missing brushes, and bottom penetration are strictly prohibited.
2. Basic items: It belongs to the standard of intermediate paint basic items.
1) Penetration, runny, wrinkled skin: none on the large surface, none on the small surface.
2) Brightness and smoothness: the brightness and smoothness are even and consistent.
3) Decorative line: the color separation line is straight, and the deviation is not more than 1mm (check by pulling the line for 5m, and check by pulling the line for less than 5m).
4) Color brush pattern: consistent color, no obvious brush pattern.
1. Before the paint wall is dry, do not clean the floor indoors to avoid dust from contaminating the wall. After the paint is dry, do not splash water close to the wall to avoid muddy water contamination.
2. After the paint wall is completed, it should be properly protected and not damaged by bumps.
3. When painting the wall, do not pollute the ground, doors, windows, glass and other completed projects.
1. Penetration: The reason is that the paint film is thin. Therefore, when brushing the paint, you should not only pay attention to not missing the brush, but also keep the consistency of the paint latex paint, and do not add too much water.
2. Obvious joints: When painting, brush up and down in a smooth manner, and the last row of pens should follow the previous row of pens. If the interval is longer, it is easy to see the obvious joints. Therefore, when painting a large area, it should be equipped with sufficient personnel. connect with each other.
3. The brush pattern is obvious: the consistency of the paint (latex paint) should be moderate, and the amount of brush dipped in the paint should be appropriate, and the brush pattern should be kept smooth to prevent the brush pattern from being too large.
4. Irregular color separation lines: Before construction, the chalk line should be drawn carefully. When brushing the color separation lines, you should rely on a straightedge, use even force, light ups and downs, appropriate amount of pen dipping, and brush from left to right.
When painting colored paint, the ingredients should be appropriate to ensure that the same batch of paint is used for each independent surface, and it should be used up once to ensure consistent color.
