Moisture (water) reacts with curing agent.

Properly control the 

temperature and humidity of the construction environment. Stop construction when the 

air humidity is greater than 

80%.

The paint is too viscous.

Use matching thinner to 

dilute the paint reasonably. 

(Use as little as possible low-

boiling solvents such as 

butyl ester, ethyl ester and 

toluene, and use solvents with a boiling point higher than 

160°.)

The solvent evaporates too fast 

during curing.

Control the temperature and extend the surface drying 

time of the paint film to 

extend the opening time of 

the paint film.
