Appearance of a denser color or lighter gloss where wet and dry layers
overlap during paint application.
Possible Causes Lapping paint
Failure to maintain a “wet edge” when applying paint.
Solution Lapping paint
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 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
