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

Possible Causes:

  1. Failure to maintain a “wet edge” when painting.
  2. Use of a low solids “economy” paint.

Solution

  1. Using a Rainbow  pure acrylic paint makes it easier to avoid lapping problems because higher solids (pigments and binder) content makes lapped areas less noticeable. If substrate is very porous, it may need a primer/sealer to prevent paint from drying too quickly and reducing wet edge time. Alkyd paints generally have superior wet edge properties.
