Wrinkling
Definition
A rough, wrinkled paint surface that occurs when the top coat dries before the bottom layer.
Causes
- Painting during extremely hot weather, which causes the paint film to dry faster on the top than the bottom
- Painting when humidity levels are high
- Applying too thick a film of alkyd or oil-based paints
- Applying a top coat before the primer or first coat has dried thoroughly
- Applying a hard finish over a softer coat without priming, or painting over a glossy surface without sanding
Solutions
- First, remove the wrinkled layers. If the layers underneath are soft, they can be removed by scraping; if they are aged, you may need to use chemical paint removers (wear safety gear as directed).
- Sand until smooth and remove dust.
- Avoid painting in high humidity or extreme temperatures(below 50º F and above 100º F).
- Areas stripped to the bare wood should be primed with a high-quality primer and allowed to dry thoroughly.
- Apply a high-quality paint. Avoid wrinkling by brushing out each coat thoroughly and allowing it to dry completely before applying the next coat.
