How to whitewash the wall, what are the steps of whitewashing, and now I will introduce to you the construction steps of whitening the wall.
1. Process flow:
Substrate treatment - repair putty, scrape putty, apply the first latex paint, apply the second latex paint, apply the third latex paint.
2. Grassroots disposal: First of all, the peeling, loose and bulging on the wall and other base layers are cleaned and chiseled, and the dust, dirt, splashes and mortar flow marks and other debris remaining on the surface of the base are cleaned up.
3. Repair putty: use plaster to level the pits and gaps on the wall and other base layers, and use No. 1 sandpaper to smooth the protrusion after drying, and sweep away the floating dust.
4. Scraping putty: The number of times of scraping putty can be determined by the flatness of the base or wall.
The normal condition is three times, and the mix ratio of putty is the weight ratio.
There are two kinds, one is the putty suitable for the room, and its mix ratio is: polyvinyl acetate emulsion (i.e. white latex) talc or large white powder 2% carboxymethyl cellulose solution = 1 5 35；The second is the putty suitable for exterior walls, kitchens, toilets, and bathrooms, and its mix ratio is: polyvinyl acetate emulsion cement water = 1 5 1, please do not use it wrong.
The detailed operation method is: the first time with a rubber scraper transverse full scrape, a scraper followed by a scraper, the joint shall not be left behind, each scraper at the end of the scraper, pay attention to the clean and neat collection. After drying, grind with No. 1 sandpaper, smooth and polish the floating putty and stains, and then clean the wall. The second time with a rubber scraper vertical full scrape, the materials and methods used are the same as the first putty, after boring, use No. 1 sandpaper to smooth and clean. The third time use a rubber scraper to find the putty, use a steel scraper to scrape the putty, scrape the wall and other base layers, and use fine sandpaper to smooth and polish after drying, pay attention not to miss the grinding or grind the putty through.
5. Apply the first latex paint coating: the first application is to brush the top plate and then the wall, and the wall should be up and then down when brushing. Clean the wall first, and then use a cloth to wipe the dust off the wall. Latex paint is usually painted with a pen, and when using a new pen, pay attention to removing the hair of the active pen. Before the application of latex paint, it should be stirred evenly and diluted with water to avoid the first application of the paint that cannot be opened. After boring, refill the putty, and polish it with sandpaper after the refill putty is boring, and clean it.
6. Apply the second time of latex paint: the operation request is the same as the first time, and it should be stirred abundantly before use, if it is not very thick, it is not appropriate to add water or add as little water as possible. In case the bottom is exposed. After the paint film is dry, use fine sandpaper to polish off the small bumps on the wall and the brush bristles, and clean them after grinding and lubricating.
7. Apply the third application of latex paint: the operation request is the same as the second application of latex paint. Because the latex paint film is boring and fast, it should be operated continuously and quickly, starting from one end and gradually brushing to the other end, paying attention to the connection between the upper and lower brushes, and the latter row of pens is immediately followed by the previous row of pens to prevent boring and then dispose of the joints.
