Roller
Marks - Stipple: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.
Solution:
Use the proper roller cover; avoid too long a nap for the
paint and the substrate. 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
"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. |
