Since flaking or cracking paint can cause a commercial building to lose its aesthetics and appreciated value, it is important that you repair them when they begin to appear. Skip to content.
Causes of Flaky and Cracking Paint While flaking occurs when paint is lifted from the underlying wall surface, cracking is caused by the splitting of a dry paint film from one or more coats of paint.
