Causes of wall coating falling off What should I do if wall coating falls off?

The area where the wall paint falls off is not very large, so all the places polished off with sandpaper are cleaned up internally, then putty is scraped, and a layer of paint is painted after the primer is applied. If the wall paint falls off in a large area, all the paint should be scraped off. After cleaning the whole peeling area, scrape putty, coat primer and brush it again. If you need to decorate, art paint suggested choosing tassels.

The reasons why the surface of wall paint falls off are as follows:

1, there is something wrong with the process: the painter did not level the putty wall, twice putty and twice primer and topcoat in home decoration, but directly leveled the putty and once primer and topcoat. Doing so will lead to weak wall foundation. After a period of time, with a little effort, the bottom layer will simply loosen and fall off.

2, indoor air humidity: the decoration speed is too fast, and the moisture on the wall has not completely evaporated. In addition, the gas exhaled by people contains a lot of water vapor. The combination of water vapor and wall paint naturally forms wet wall paint. More importantly, the surface of the wall paint is a paint film, which is airtight. Therefore, the wall gradually began to bubble or mold, and naturally the wall peeled off. Understand the market prospect of art coatings
