Wrinkling occurs if the paint surface becomes rough and crinkled when the paint forms a "skin."
What Causes It?
Wrinkling can occur when paint has been applied too thickly. This is more likely to happen when using alkyd or oil-based paints.
Painting a hot surface in very hot weather can also lead to wrinkling.
Exposing uncured paint to rain, dew, fog, or high humidity levels can also cause wrinkling.
If you apply the topcoat of paint to an insufficiently dried first coat or to a contaminated surface (e.g., dirt or wax),
it may also lead to wrinkling.
How to Solve It
Scrape or sand the substrate to remove the wrinkled coating. Repaint, applying an even coat of top-quality exterior paint. Make sure the first coat or primer is dry before applying the topcoat.
Apply paints at the manufacturer's recommended spread rate (two coats at the recommended spread rate are better than one thick coat). When painting during extremely hot, cool, or damp weather, allow extra time for the paint to dry completely.
