Wrinkling

A rough, crinkled paint surface which occurs when uncured
paint forms a "skin."
Possible Cause:
-
Paint applied too thickly (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
on the bottom.
-
Exposure of uncured paint to high humidity levels.
-
Applying top coat of paint to insufficiently dried first
coat.
-
Painting over 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 the top
coat. Repaint, applying an even coat of top quality exterior
paint. When painting in extremely hot, cool or damp weather,
allow extra time for drying.
