Loss of paint due to poor adhesion. Where there is a primer and top coat, or multiple coats of paints, peeling may involve some or all coats.

Possible Causes:

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 blitering of paint (see Blistering).
