Loss of adhesion of the paint film caused by high levels of moisture that penetrate the film and eventually push the film away from the substrate.


  • Excessive moisture in a home resulted from cooking, showering, or the use of a humidifier, vaporizer, or hot tub.
  • Excessive moisture in a home due to a high level of humidity in the basement and/or foundation.


See Lead Information.

  • Proper ventilation can fix most interior moisture problems. High-moisture areas such as bathrooms with showers should have exhaust fans installed.
  • Proper ventilation in the walls and/or roof of the home may be necessary. Heavily insulated and sealed homes need a means for moisture to escape, such as roof vents and possibly outside wall vents.
  • Allowing moisture to escape via open windows is an option.
  • If high levels of moisture/humidity exist in a basement, the cause of this must be determined and fixed.
  • Once proper ventilation has been installed, peeling paint should be removed and the underlying surface cleaned and primed. Test the coating in a 6" to 12" radius around any peeled areas to be sure its adhesion is adequate. Follow label and data page directions for proper surface preparation.
