Failure of dried paint to obscure or hide (e.g. ability to fully conceal painted surface) the underlying color or surface to which it is applied.
DESCRIPTION
POSSIBLE CAUSE
- Applying too thin of a paint film.
- Use of paint with low hiding characteristics.
- Use of a paint that is much lighter or darker than the previous coat.
- Use of the wrong type or nap size of roller cover. Use of the wrong type or size of brush.
- Painting over a porous surface that absorbs the coating.
- Poor flow and leveling.
- Thinning/reducing the coating.
SOLUTION
- Follow label and data page directions for the appropriate film build (e.g. thickness of each coating layer).
- Prime the surface with the appropriate Sherwin-Williams Color Prime® system of gray-shaded primers for the color of the topcoat.
- Determine the correct roller cover type or nap based on the coating being applied and the surface to be coated. On smooth surfaces, a mohair, 1/4", or 3/8" roller nap is usually sufficient. On textured surfaces, a 3/4" nap or greater is needed.
- Prime porous surfaces before topcoating.
- Allow proper drying time before recoating.
