Bubbles resulting from localized loss of adhesion, and lifting of the paint film from the underlying surface.
he washing down of chalk from an excessively eroding paint onto another area below (a brick foundation, for example), ruining its appearance (see Chalking).
Formation of fine powder on the surface of the paint film during weathering which can cause color fading.
The splitting of a dry paint film through at least one coat, which will lead to complete failure of the paint.
