How-To

Detailed solutions from PPG Porter® to the most common paint problems faced by both painting professionals and do-it-yourselfers.

Interior

Poor Hiding:

The failure of paint to obscure the surface to which it is applied.

Possible Causes

  • * Use of a low-quality paint
  • * Use of low-quality tools or the wrong kind of roller cover
  • * Use of an improper combination of tinting base and tinting color
  • * Use of a paint that is much lighter in color than the substrate, or that primarily contains low-hiding organic pigments
  • * Application of paint at a higher spread rate than recommended

Solutions

If the substrate is significantly darker or is a patterned wallpaper, it should be primed before applying a top coat. Use a top-quality paint for better hiding and flow. Use the recommended roller nap, if rolling. Follow manufacturer's recommendation on spread rate. If using tinted paint, use the correct tinting base. Where a low-hiding organic color must be used, apply a primer first.
