The topcoat was applied over a painted surface that was dirty or not properly cleaned, thus the topcoat of paint did not bond or stick properly.
- There are two basic sources of dirt or pollutants that weakened a bond.
- With age, paint oxidizes resulting in water-soluble chemicals of chalks and salts on the surface.
- Pollutants, like dust (plus other air particle pollutants) and sulfur settle on the home’s painted surfaces.
Poor cleaning of weathered paint will often cause inter-coat peeling a couple of years after repainting.
- Paint applied over a damp or wet surface may also experience inter-coat peeling.
Note that if the paint is peeling and there is not another coat of paint under it; then it is not inter-coat peeling. Moisture in the wood may also cause paint to peel.
