Roller Painting

House Painters Sydney

Most home interiors are painted with a roller, though a brush is probably used for the corners. Rollers are popular for this type of painting because they can cover large flat surfaces quite quickly and because they give a pleasant semi-textured finish.

 

Roller painting, like any painting, requires some skill. But it is not too difficult to get reasonable results if we know the right procedure.

Some terms:

Roller cage (aka Roller frame) – This is the metal roller frame attached to a handle, one of the most basic tool for roller painting. the width of the cage determines which sized roller you can use.

The Tray – This holds the paint for roller painting. Ideally the tray should be slightly wider than roller cage. A tray is necessary because a roller is too big to be put inside a paint can. The tray will have ridges along the surface, and slope toward one end.

The Nap – This is depth of the painting surface on a roller. A thicker nap (20 mm) hold more paint. A thinner nap (5 mm) hold less paint but gives a much smoother finish. Most interior Matt painting on walls uses a medium 9mm nap. Only gloss paint requires 5mm. Thick naps are used for brickwork.

 

Technique

  • The wall you are painting should be cleaned and prepared. Apply undercoat is required.
  • Many painters like to use a brush to do the edges of the walls first, then use the roller when the brush paint is dry.
  • Pour the paint into the tray. It will need to be on a flat surface. You will need to estimate the right amount, though you can always add a little more if you start to run low. The tray should never be more than half full, probably less than that.
  • If you are using water based paint you should wash the roller before hand, and start using it while it is still damp. Remove any loose fibers form the roller.
  • Roll the roller in the tray till it is fully covered with paint, the run it across the rides of the tray to remove excess paint.
  • Apply the roller to the wall, with light pressure. Start at waist level, and paint in a Zig-Zag pattern. It is fine to go over the same area while the paint it still wet.
  • Return to the tray and apply more paint to the roller as required.
  • Cover the entire wall with the roller. Do section of about 1 meter square. Do not paint over an area once the paint starts to dry.
  • When finished. Wash the roller and tray with water.
  • A second coat after the first coat has dried may be necessary for the best results.
