Peeling - Under Eaves

DESCRIPTION
Loss of adhesion of a coating under eaves, porches, or other protected areas.
POSSIBLE CAUSES
  • Under eaves, porches, or other protected areas, the natural cleaning effect of weather does not occur, and air pollution or other contaminants can build up.
  • Salts, which can form during the life of the existing paint coating, were not removed before a new coat of paint was applied. These salts form an invisible film, preventing the previous coating to bond with the new topcoat.
  • Paints are applied to old hard and glossy paint films.
  • Insufficient surface preparation.
SOLUTIONS
Follow label and data page directions for proper surface preparation methods for the coating. Extra attention should be directed to areas that are not exposed to direct weathering.

Test the coating in a 6" to 12" radius around peeled areas to be sure the adhesion is adequate.
