Roller Marks / "Stipple"
 

Description:
Unintentional textured pattern left in the paint by the roller.

Possible Cause:
• Use of incorrect roller cover.

• Use of low grades of paint.

• Use of low quality roller cover.

• Use of incorrect rolling technique.

Solution:
Use the proper roller cover. Certain sheens such as semigloss and gloss work best with specific types of roller covers. Avoid too long a nap for the paint and the substrate. Short naps are used for very smooth surfaces whereas longer naps (1/2" and above) are used for rough, textured surfaces. Use quality rollers to ensure adequate film thickness and uniformity. High quality paints tend to roll on more evenly due to their higher solids content and leveling properties. Pre-dampen roller covers used with latex paint; 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 "N" 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.
