Peeling
Loss of paint due to poor adhesion. Where there is a primer
and top coat, or multiple coats of paint, peeling may involve
some or all coats.
Possible Cause:
-
Seepage of moisture through uncaulked joints, worn caulk
or leaks in roof or walls.
-
Excess moisture escaping through the exterior walls (more
likely if paint is oil-based).
-
Inadequate surface preparation.
-
Use of lower quality paint.
-
Applying an oil-based paint over a wet surface.
-
Earlier blistering of paint (see blistering).
Solution:
Try to identify and eliminate cause of moisture (see efflorescence/mottling).
Prepare surface by removing all loose paint with a scraper
or wire brush. Sand rough surfaces and prime bare wood
before repainting with a high quality acrylic latex
exterior paint for best adhesion and water resistance.
