We all know the sun can give us wrinkles, but did you know it can do the same to your paint? Wrinkling is a rough, crinkled paint surface that occurs when paint forms a 'skin'.


Possible Cause

In addition to hot weather, wrinkling can also be caused by:

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



Scrape or sand substrate to remove the wrinkled coating. Then, repaint with an even coat of top quality exterior paint at the recommended application rate.



If painting during extremely humid, cool or damp weather, allow extra time for the paint to dry completely. Apply paints at the manufacturer's recommended spread rate (two coats at the recommended spread rate are better than one thick coat).

Cracking / flaking

Cracking or flaking is the splitting of a dry paint film. This is a problem that needs fixing as it can lead to complete failure of the paint. For each problem you’ll find a guide to identifying it, its causes and solutions.
