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.
