Chalking

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.
