Description of problem:
Clouding occurs because of the uneven distribution of the metallic flakes. This phenomenon creates some dark spots and is called clouding.
Causes:
-
Spraying viscosity.
-
Spraying technique and pressure.
-
Spray gun set up.
-
Unsuitable thinner.
-
Unsuitable spraying temperature.
-
Flash off time incorrect.
Preventive measures:
-
Adjust material viscosity, spray gun set-up spraying technique (Keep gun perpendicular to panel), flash off time and pressure.
-
Use recommended thinner.
-
In the case of monocoat 2K metallic you may apply a mist coat immediately after the last spray coat.
