Step by Step Instructions

Clear your work area and use drop cloths or dust sheets to protect the floor and any fittings or furniture that could not be removed from the room.

At all times, make sure you wear protective clothing to shield your eyes and skin when using fillers and cleaners.

If the walls are finished in untreated plaster then you must apply a sealing agent before you begin any repairs to the surface. The agent will reduce the natural porosity of the plaster so that any wallpaper or paint adheres well.

Fill in all surface flaws such as cracks, splits and small cavities with a suitable filler. Some fillers are made for special purposes and you need to select one to suit the damage you are repairing.

Use a filler knife or spatula to apply the filler by driving the mixture into the damaged areas in firm single strokes.

Top Tip: Keeping your spreader wet with cold water will ensure a smoother finish that may not require further treatment.

If the repair is still uneven after the filler has dried, sandpaper the rough patches until level and smooth.

Larger damaged areas with loose plaster or deeper holes should be cleaned out and fresh plaster applied.

Lining paper or a complete plaster skim may be necessary for very rough wall surfaces.

Treat any stains or damp patches with an appropriate sealant to eliminate any unsightly marks showing through your wallpaper or paint.

Top Tip: Investigate the origins of any damp patches or stains to prevent further blemishes appearing later on after the decoration is finished.

Using sponges and cloths, clean the walls with a sugar soap solution to remove any grime, dust or grease spots.

Finally, wash down all walls with clean, fresh water to remove any sugar soap residue.
