Wrinkling

 
Wrinkling

A rough, crinkled paint surface, which occurs when uncured paint forms a 'skin'.

POSSIBLE CAUSES

  • Paint applied too thickly (more likely when using oil based paints)
  • Painting during extremely hot weather or cool damp weather, which causes the paint film to dry faster on the top than the bottom
  • Exposing uncured paint to high humidity levels
  • Painting over a contaminated surface, e.g. dirt or wax

SOLUTION

Scrape or sand substrate to remove wrinkled coating. If using a primer, allow it to dry completely before applying a topcoat. Repaint (avoiding temperature/humidity extremes), applying an even coat of top quality interior paint.
