The surface of the coating turns white: there seems to be a layer of mist on the surface.

Answer: Reason: The construction environment is humid and prone to frosting on the coating, or the curing agent contains water, causing the amine in the curing agent to precipitate and produce white mist that accumulates on the surface. Solution: Avoid construction in environments with high humidity; Avoid construction on surfaces with a temperature difference exceeding 3 ℃; In early spring, the temperature of the ground and walls is much lower than room temperature, especially on smooth surfaces where condensation is prone to occur. Before construction, windows should be opened to minimize the temperature difference between room temperature and the ground.
