Wrinkling in paintwork can be identified by a rough, crinkled paint surface, which occurs when uncured paint forms a 'skin'.
It can be caused by any of the following:
- Applying paint too thickly (this is more likely when using alkyd or oil-based paints)
- Painting during extremely hot weather or cool damp weather, which causes the paint film to dry faster on top than underneath
- Exposing uncured paint to high humidity levels
- Applying a top coat of paint to insufficiently cured primer
- Painting over a surface contaminated with dirt, dust or wax
First, scrape or sand the substrate to remove wrinkled coating. If using a primer, allow it to dry completely before applying top coat. Then, repaint your surface in ideal conditions, applying an even coat of top quality interior paint.
