CHALKING

Oxidizing, Fading, Weathering

A chalky white appearance on the surface of the paint film

CAUSE

Pigment is no longer held and protected by resin, resulting in a powder-like surface and lack of gloss due to:

• Natural weathering of the paint film;
  
• Improper application of paint material;
  
• Using generic thinner/reducer and/or hardener in the paint material;
• Excessive use of mist/fog coats when applying single stage metallic finishes.

REPAIR

Compound to remove oxidation and polish to restore gloss.

Or, sand to remove "weathered" paint film and refinish.

PREVENTION

• Weekly washing and occasional polishing or waxing will remove oxidation from the finish.
  
• Thoroughly stir, shake or agitate all paint materials.
  
• Use the recommended thinner/reducer,hardener, and measure accurately.
  
• When spraying single stage metallic finishes, apply mist/fog coats panel by panel while finish is still wet.
