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

Possible cause

  • Failure to maintain a 'wet edge' when applying 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 help produce a smooth, uniform appearance.

It is also wise to minimise 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). Solvent-based paints generally have superior wet edge properties.
