The Problem: Failure of the dried topcoat to obscure or “hide” the underlying surface.
Causes: Using products with low levels of titanium dioxide (the primary covering element in paint). Using paint with poor flow and leveling qualities (see Poor Flow/Leveling). Using low quality tools and/or the wrong roller cover. Over thinning or spreading the paint. And using a low-grade paint with a much lighter color than the substrate.
How-to-fix: Use a tinted primer on substrates with a color significantly different than the new topcoat. Use top-quality paints with high levels of titanium dioxide. Finally, apply the topcoat with high-grade tools and a roller cover with the correct nap length.
