Wrinkling

Wrinkling

During the drying process, the paint surface dries at different rates, causing unevenness and sudden shrinkage, which leads to wrinkling of the topcoat. This results in irregularly shaped wrinkles.

Cause:

1. Paint layers that are too thick cause the surface to dry while the underlying layer remains wet.
2. Poor drying conditions:
   • Too slow or too high temperature.
   • Too strong or too weak air circulation.
   • Contaminated air.
3. Insufficient flash-off time or high temperature, leading to rapid drying or exposure to sunlight.
4. Wrong type of thinner: excessive penetration causes swelling and wrinkling.
5. Excessive air-drying time for synthetic resin coatings before oven baking.

Correction:

1. Allow the paint surface to dry completely.
2. If wrinkling is minor, sand the area and polish.
3. In severe cases, remove the existing paint and reapply the entire paint system.

Recommended products to prevent and fix potential issues:

• Abrasives and accessories

• Paint spray guns
