So under normal circumstances, even if the humble construction team does something else or suspends work for two days, it should try not to paint when it rains.

2. The humidity of the wall should not be too large. Generally, the humidity of the wall of the latex paint application is less than 10%. If the humidity is too high, the adhesion of the paint film will be affected and the paint film will be blistering and falling off.

3. The alkalinity of the wall should not be too strong. It is generally required that the alkaline pH of the latex paint construction wall should be less than 10.
