Roller marks / “stipple”

Roller Marks / “Stipple”

This refers to the unintentional textured pattern – or ‘stipple’ – that may be left in the paint by the roller.

POSSIBLE CAUSES

  • Using lower grades of paint.
  • Using an incorrect roller cover.
  • Using a low-quality roller.
  • Using the incorrect rolling technique.

SOLUTION
High-quality paints tend to roll onto a surface more evenly, due to their higher solids content and levelling properties. Use a good-quality roller to ensure that the paint is applied uniformly, and to the appropriate thickness. Always use the recommended roller cover and nap length for the paint and surface you are using.

Before applying water-based paint, dampen your roller cover, and shake out any excess water. Begin rolling at a corner near the ceiling, and work down the wall in sections. Spread the paint in a zigzag ‘M’ or ‘W’ pattern, beginning with an upward stroke to minimise spatter. Then, without lifting the roller from the surface, fill in the zigzag pattern using even, parallel strokes. Don’t let paint build up at the ends of the roller. If you’ve used a roller to apply paint to a door, lay off with a brush – that is, run a brush lightly over the surface to minimise any traces of roller texture.
