Lapping
 

Description:
Appearance of a darker/denser color or higher sheen where wet and dry layers overlap during paint application. This results in a higher paint film where the layers "overlap".

Possible Cause:
• Failure to maintain a "wet edge" when painting. Essentially, some areas are receiving 2 coats.

• Use of a low solids "economy" paint.

• Painting under high temperatures

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).  Oil paints generally have superior wet edge properties.
