The lifting of paint from the underlying surface in the form of flakes. Flaking is generally preceded by cracking or checking, and will occur over different surfaces.
- Cracking of exterior wood and plywood as it expands and contracts in response to temperature and humidity changes, which is transmitted through the coating.
- Poor paint penetration, especially on wood with an excessive amount of "flat" hard grain pattern, which is smooth, hard, and nonporous.
- Poor surface preparation and/or applying too thin a coat of paint.
- Scrape, sand, or scrub with a wire brush to remove all loose and peeling paint.
- Sand if needed to fresh wood. Wood must not be allowed to weather prior to coating.
- Follow label and data page directions for surface preparation for the coating.
