First, the reason for the emergence of latex paint is that the temperature of the construction process is low, no continuous coating film is formed, and local cracks appear between the paint films, and then fall off when exposed to water;
Second, the base layer is not cleaned up, dust, oil and other dirt appear, which will result in poor adhesion of the coating film to the base layer, and easy to peel off;
Third, the base layer batch scraping putty strength is low, the putty layer is not dry, that is, the latex paint is applied; the base layer is too smooth, so that the adhesion of the coating film is not good. Peeling off:
How to avoid the fall of latex paint: According to the above factors, the construction period preparation work should be done in a targeted manner. Do not use low temperature construction, and choose the wall putty with good quality, durability and waterproofness to do the basic construction process. This can well avoid the appearance of latex paint falling off.
