Wrinkling
 
 << Back
Description:
Wrinkles appear on the painted surface after application.

Cause:
  • The paint was applied too thick.
  • The surface was not properly prepared, de-glossed, or primed.
  • An incorrect primer or sealer was used.
  • The top layer of the paint dried faster than the rest of the coating.
  • There was not enough time allowed between coats.
  • Using incompatible products on top of each other; for example, using an alkyd enamel over lacquer based product or lacquer over enamel.
  • Painting during the incorrect temperature and humidity ranges.
Prevention:
  • Follow the surface preparation recommendations on the label or product data sheet.
  • Always use the correct primer or sealer.
  • Air, substrate, and paint temperature should be between 50F and 90F unless otherwise stated.
  • Do not apply products that cure at different rates on top of each other. For example, a lacquer product must be used on top of another lacquer product.
Cure:
Remove all paint and then properly prepare and coat the surface.
