Common Paint Problems

How-To

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

Interior

Roller Marks:

An unintentional textured pattern left in the paint by the roller.

Possible Causes

  • * Use of incorrect roller cover
  • * Use of lower grades of paint
  • * Use of low-quality roller
  • * Use of incorrect rolling technique

Solutions

Use quality rollers to ensure adequate film thickness and uniformity. Pre-dampen roller covers used with latex paint and shake out excess water. Don't let paint build up at roller ends. Begin rolling at a corner near the ceiling and work down the wall in three-foot square sections. Spread the paint in a zigzag "M" or "W" pattern, beginning with an upward stroke to minimize spatter; then, without lifting the roller from the surface, fill in the zigzag pattern with even, parallel strokes.

Just as importantly, use high-quality paints, which roll on more evenly due to their higher solids content and leveling properties.
