Loss of Gloss

Loss of Gloss: Beautiful gloss in wet paint, but gloss disappears as the surface dries or ages.

Description:

Loss of gloss is most often caused by improper handling of the paint or substrate, or unfavorable conditions during the painting process.

Cause:

1. A rough substrate and coarse sandpaper cause excessive absorption of the topcoats.
2. An overly thick and uneven metallic basecoat causes the clearcoat to sink into the grooves.
3. Too thick a primer layer and insufficient drying of the primer or surface.
4. Insufficient drying time before polishing.
5. Incorrect paint-to-thinner ratio.
6. Poorly selected thinner not suited to the painting conditions.
7. Poor spray booth conditions can cause moisture to remain in the topcoat:
   1. Insufficient ventilation or poor air circulation.
   2. Too hot, too cold, or too humid an environment.

Repair:

1. Polish the surface to restore gloss once the paint is completely dry. If that does not help, lightly sand and repaint the surface.

Recommended products to prevent and correct possible issues:

• Abrasives and accessories

• Paint spray guns
