POOR SHEEN UNIFORMITY

Shiny spots or dull spots (also known as “flashing”) on a painted surface; uneven gloss.

POSSIBLE CAUSES:

• Uneven spread rate.
• Failure to properly prime a porous surface, or surface with varying degrees of porosity.
• Poor application resulting in lapping (see Lapping).

SOLUTION:

• New substrates should be primed/sealed before applying the top coat to ensure a uniformly porous surface.
• Without the use of a primer or sealer, a second coat of paint will more likely be needed.
• Make sure to apply paint from “wet to dry” to prevent lapping. Often, applying an additional coat will even out sheen irregularities.
