Occurs where wet and dry layers overlap during painting. Avoid with paint area management and technique.
LAPPING PROBABLE CAUSES
Wet and dry layers overlapping. Too much heat or wind during application. Inadequate stirring and improper thinning. Extremely porous surface. Painting too large an area at one time, such as trying to go from the top to the bottom.
Another coat of paint evenly spread usually will cover lap marks. If the finish coat is relatively transparent or if the surface is overly porous, a primer or second coat may be necessary. Always paint from wet to dry and in small sections to keep a wet edge.
PRIMERS & INTERIOR FINISHES
Priming is essential for better adhesion, sheen uniformity, mildew control and durability. Select a top quality interior paint in the color and sheen of your choice.
