Main paint problem list

Exterior problem

Lapping: Appearance of a denser color or higher gloss where wet and dry layers overlap during paint application.

Possible Cause:

Failure to maintain a "wet edge" when applying paint.

Solution: Maintain a wet edge when painting by applying paint toward the unpainted area and then back into the just-painted surface. This technique (brushing from "wet to dry", rather than vice versa) will help produce a smooth, uniform appearance. It is also wise to minimize the area being painted and plan for interruptions at a natural break, such as a window, door or corner (especially important when applying stain to bare wood). Alkyd paints generally have superior wet edge properties.
