Wrinkling: A rough, crinkled paint surface, which
occurs when uncured paint forms a "skin".
Possible Causes:
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. Exposing uncured paint to high
humidity levels. Applying top coat of paint to
insufficiently cured primer. 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
top coat. Repaint (avoiding temperature/humidity
extremes), applying an even coat of top quality interior
paint.
