Peeling:
Loss of paint due to poor adhesion. Where there is a primer and a top coat, or multiple coats of paint, peeling may involve some or all coats.
Possible Cause:
- Seepage of moisture through un-caulked 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. Prepare surface by removing all loose painting with scraper or wire brush, sand rough surfaces, prime bare wood. Repaint with a top quality acrylic latex exterior paint for best adhesion and water resistance.
