A rough, crinkled paint surface occurring when paint forms a "skin."

• Paint applied too thickly (more likely when using alkyd or oil-based paints).
• Painting a hot surface or in very hot weather.
• Exposure of uncured paint to rain, dew, fog or high humidity levels.
• Applying top coat of paint to insufficiently dried first coat. ¥ Painting over contaminated surface (e.g., dirt or wax).

• Scrape or sand substrate to remove wrinkled coating. Repaint, applying an even coat of top quality exterior paint. Make sure the first coat or primer is dry before applying the top coat. Apply paints at the manufacturer's recommended spread rate (two coats at the recommended spread rate are better than one thick coat). When painting during extremely hot, cool or damp weather, allow extra time for the paint to dry completely.
