Temporarily or permanently, surface of the paint film loses gloss and becomes foggy or milky after spraying.

Cause
A. Fast drying solvent or unbalance of thinner could make moisture getting into the film.
B. Air from spray gun and thinner drop the temperature of the substrate by the dew point and make moisture getting into the film.
C. Applying on a humid day.
D. Using a lot of hydrophilic solvent.

Repair
For lacquer types, add 5~10% of retarder thinner(DR-2590R). Retarder thinner is recommended only for the final coating.

Prevention
A. Use slow or retarder thinner, or proper thinner for the temperature.
B. Lower the air pressure during spraying to minimize the substrate temperature falling.
C. Avoid the application on a humid day.
