Wrinkling
Wrinkling refers to the rough, crinkled, appearance of the paint surface that occurs when uncured paint forms a ‘skin’.
POSSIBLE CAUSES
- Applying paint too thickly (particularly when using solvent-based paints).
- Painting during extremely hot weather or cool damp weather, which causes the paint film to dry faster on top than on the bottom.
- Exposing uncured paint to high humidity levels.
- Painting over a contaminated surface (dirt or wax, for example).
SOLUTION
Scrape or sand the surface to remove the wrinkled coating. If using a primer, allow it to dry completely before applying a topcoat. Repaint the surface, applying an even coat of top-quality interior paint. Try to avoid painting in extreme temperatures or humidity.
