Rippled paintwork surface with uneven grooves. The upper coat dries faster than the coat under it. Occurs only with synthetic resin paints.


  1. Synthetic resin applied too thick
  2. Insufficient addition or no addition of drier
  3. Unfavourable drying conditions (e.g., very high ambient temperature)
  1. Keep to recommended film builds
  2. Add amount of drier specified in the mixing formula
  3. Ensure that drying conditions are favourable


For minor wrinkling, allow the affected surface to dry completely and then sand it off to a well-cured coat and apply a new finish. For severe wrinkling, strip the paint layer completely and repaint.
