Peeling Paint – what to do about it

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 CAUSES:
• Seepage of moisture through unsealed joints, worn sealant or leaks in roof or walls.

• Excess moisture escaping through the exterior walls (more likely if paint is solvent-based).

• Inadequate surface preparation.

• Use of lower quality paint.

• Applying a solvent-based paint over a wet surface.

• Earlier blistering of paint (see Blistering).

SOLUTION:

• Painter Decorators  at John Bradley’s will try to identify and eliminate source of moisture. Prepare surface by removing all loose paint with scraper or stiff wire brush, sand rough edges, and apply appropriate primer. Repaint with a top quality acrylic water-based exterior paint for best adhesion and water resistance.
