DESCRIPTION

Loss of adhesion of a coating to the substrate (e.g. the surface that was painted) or an earlier coating. Where there is a primer and topcoat or multiple coats of paint, peeling may involve some or all of the coats.

POSSIBLE CAUSE

• Seepage of moisture through uncaulked joints or worn caulk.
• Leaks in roof or walls, or excess moisture escaping through the walls from the interior.
• Painting over a dirty, wet, or glossy surface.
• Painting over a coating that already has marginal adhesion..
  
  

SOLUTION

Remove old, loose, cracked caulk; prime as needed; and caulk with the appropriate product.

Find and repair any source of water.

Follow label and data page directions for proper surface preparation methods for the coating.
