Sanderson Paint - An Introduction to Colour

Make sure all surfaces to be painted are dry, sound and free from dirt.

Rub down glossy surfaces to provide a good “key” for new paint.

Remove all dust and debris from the surface as this could adversely affect the appearance of the finished job.

For best results, all woodwork and metalwork should be primed. The reasons for this are:

  • It will make the finish coat look better and work more effectively
  • To seal unpainted surfaces or sanded surfaces, providing a suitable surface for the finish coat
  • To prevent darker colours from bleeding through when painting from a dark to a light colour

For drying times visit the “Paint Finishes” section on our website and always follow the advice on the can.

  1. Roll up rugs, move furniture to the centre of the room and cover. Place dust sheets or newspaper on the remaining floor space.
  2. Loosen wall sockets etc. and remove switch plates, door and window fittings.
  3. Make sure surfaces to be painted are sound by removing loose paint, plaster or wallpaper.
  4. If you’re painting over wallpaper ensure all seams are firmly glued down.
  5. Remove any loose plaster from cracks, holes and other imperfections, fill and sand, leaving a smooth finish ready for painting.
  6. Clean dust from the walls with a damp cloth and vacuum the room before you begin painting.
  7. For best results, use good quality equipment, including a 9-inch roller tray and paint roller. Any larger than this will be heavy, inaccurate and difficult to handle.
  8. Use the correct roller type for the surface you’re painting. Generally speaking, the smoother the surface, the shorter the roller sleeve’s “pile”.

Stir paint thoroughly before use.

When working on ceilings or in cramped areas, decant a little paint from the can into a small, light container. A clean plastic food-storage container with a tight-fitting cover is ideal for emulsion paint; a metal can is better for oil based paint.

Brushes: Select appropriate brushes for the type of paint being used. Straight-edge brushes handle all tasks nicely. Some people find angled brushes more comfortable in tight spots; they are especially good for painting trim and straight edges.

Load a 2- or 3-inch straight-edge brush. The correct way is to dip the bristles one-half to two thirds of the way into the paint. Don’t get paint on the ferrule (the metal wrapper that holds the bristles). Clear excess paint from one side of the brush by dragging it against the side of the container; don’t drag both sides. Always apply the loaded side of the brush to the wall.

Working from the ceiling down, paint a 3-inch frame around all the edges of the room that would be awkward to roll. Paint the corners; outline the ceiling; edge the skirting board and architraves, windows and doors, baseboard, light fixtures, plugs and switchplates. Painters call this “cutting in’’.

Let the paint dry. Now you are ready to use a roller to cover the large areas.

Slip the appropriate sleeve onto the roller cage (handle). Attach the roller extension handle.

Pour about an inch of paint into the deep reservoir end of the paint tray. Leave the other end of the tray clear.

Dip the roller into the tray, and move it back and forth on the roller bed. The roller should be well saturated with paint, but not dripping. Once again, you will work from the ceiling down. Roll an area about 2 feet square. Work the roller up, down, and across until you’ve covered the area evenly. Cover the entire ceiling and wall this way, square by square.

If paint begins to build up on the wall at the edges of the roller, gently roll out the lines immediately. Some paints can start drying quickly, so don’t go back over tacky paint.

When painting the trim (picture rail, skirting boards etc) work from the ceiling downwards.

To avoid varying sheen levels when eggshell paint is dry, thoroughly mix prior to application. Only apply sufficient paint to maintain a wet edge and apply even coats over the entire surface to avoid overlap marks.

When painting windows, try not to lay on paint too thickly or it may cause problems. When painting sash windows, slide them up and down during the job to stop them from sticking shut. Where possible, leave windows open for at least 24 hours while drying.

Both of these paints are water based, so water and possibly a little soap is all that’s needed to clean brushes and rollers. Rinse under warm water to remove excess paint, adding a few drops of washing-up liquid if necessary. Press dry with kitchen roll or paper towels, and ideally store brushes hanging up.

Rinse brush thoroughly in a suitable container of White Spirit until paint has been removed from bristles. Press dry with kitchen roll or paper towels and ideally store hanging up.

Keep paint tightly sealed in its original container, away from extreme temperatures. Sheds, garages and basements may get too cold, which could damage the paint.

Check your local authority’s waste disposal guidelines for advice on how to dispose of paint cans, waste paint, and cleaning solvents responsibly.
