Poor sheen uniformity leads to shiny spots or dull spots (also known as "flashing") on a painted surface.
Use the following preparation and painting techniques to avoid dull or shiny wall spots and patches.
What Causes Poor Paint Sheen Uniformity?
- Unevenly spreading the paint as you apply it
- Failing to maintain a wet edge, which can lead to lapping
- Not properly priming a porous surface, or a surface with variable porosity
How to Prevent Poor Paint Sheen Uniformity
- New substrates should be primed and sealed before applying the top coat to ensure a uniformly smooth surface. Without the use of a primer or sealer, a second coat of paint will more likely be needed to produce a uniform sheen.
- Make sure to apply paint from "wet to dry" to prevent lapping.
- Applying an additional coat of paint will even out sheen irregularities.
