Preparing Indoor Surfaces

Preparing Indoor Surfaces

Metalwork

  • Wash and lightly rub down sound paintwork.
  • Remove peeling or blistered paint with a wire brush; treat any rust. Apply a rust inhibitor and an appropriate primer (some preparations combine the two functions) to exposed metal.
  • Use a chemical stripper to remove any build-up of paint - especially if, say, it interferes with the action of metal-framed windows.

Woodwork

  • If the surface has been previously painted and the finish is in good condition, wash and lightly sand it.
  • If the surface has been previously painted and the finish is in poor condition, strip back the paint to bare wood.
  • If the surface is unpainted or has been stripped, you can give it a translucent finish or paint it.

Sound Plaster Work

  • Wash walls and ceilings with warm water and sugar soap. Sugar soap is available in powder, liquid, and concentrated form; follow the recommendations on the packaging. You may need to rub down minor imperfections in brand-new plaster.
  • Always wash walls from the bottom up. Water running down on to a damp surface disperses, whereas if it runs on to a dry surface it may leave indelible dribble marks that show through paint.
  • Unless the surface is very dirty, you don't need to rinse the walls after washing. If you do rinse, work from the top down.

Plaster Work With Problems

  • Fill minor blemishes, such as fine cracks or holes left by picture hooks, and allow them to dry.
  • Major defects, such as damp, large cracks, or extensive mould, could be symptoms of another more serious problem, which must be put right before you do any decorating.
