How many processes does it take to decorate and paint the wall?

Latex paint is generally used to paint walls, but now it is rarely used to scrape porcelain. Latex paint is still very environmentally friendly and clean, so I think you are talking about brushing latex paint. Brush latex paint is generally the process of cleaning and repairing the wall surface first, keeping it flat, then scraping putty, then brushing primer, and finally brushing topcoat, as follows:

1, base treatment: different materials of base should be treated in different ways, and the treated surface should be smooth, dry, free of oil and floating dust. The moisture content of concrete or gypsum base shall not be greater than 10%, and that of wood base shall not be greater than 12%. At room temperature, the age of plastering surface shall not be less than 14d, and the age of concrete matrix shall not be less than one month.

2. Full putty: the putty for scraping the wall is made of white latex paint, talcum powder or white powder and 2% carboxymethyl cellulose solution, and the ratio is 1:5:3.5 (weight ratio). The first putty requires horizontal scraping, and the second putty requires vertical scraping. Require a flat, even, smooth and secret room; The angles and edges of the lines are neat. After scraping, there should be no leakage, no seams, and no pollution to doors and windows. After drying, smooth it with sandpaper. Every piece of putty should be polished with sandpaper, and every piece of sandpaper should smooth the wall surface, leaving no floating putty and scratches, and clean up the floating ash.

3. Primer: If high-grade latex paint is used, the priming process should be added after the second putty application. The sealing primer can be applied by roll coating or spray coating. When coating, the coating shall be uniform and shall not be omitted. If the sealing primer penetrates into the base course, it needs to be repainted.

4. Brush latex paint. The coating film of latex paint should not be too thick or too thin during construction. Too thick is easy to sag and wrinkle, too thin can not play the role of coating. Generally, it is advisable to cover the bottom completely, not to penetrate the virtual shadow, and to have a uniform surface. The brushing frequency is generally twice, and the brushing frequency can be appropriately increased when necessary. At room temperature, the interval between poems of each painting is about 4 hours.

5. Polishing: After the first coating of latex paint is completed for 4 hours, polish it with fine sandpaper. If it is wet, it is not dry after 4 hours, the time should be extended, and then polished after drying.
