Unintentional textured pattern left in the paint by the roller.
- Use of incorrect roller cover.
- Use of lower grades of paint.
- Use of low quality roller.
- Use of incorrect rolling technique.
- Use the proper roller cover; avoid too long a nap for the paint and the substrate.
- Use a quality roller 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 (3′) 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.
