Filling Holes and Cracks

Once all the old wallpaper has been removed, the walls need to be made good. Any cracks, gaps or damage from stripping needs to be repaired.

Use a tube of filler to repair small holes and use a powder or ready mixed filler for large holes or cracks. When the filler has gone hard, sand down using a block of wood and some sand paper. Wash down the walls with sugar soap or a similar cleaner to remove dirt and traces of old adhesive.

Top TipSave some money and use an old margarine tub as a mixing bowl.

DIY Projects - Filling holes & cracks


Remove loose plaster

Remove any loose pieces of plaster, then use a brush to dust the area before applying the filler.

Mix paste

A powder filler is the cheapest method. Use a clean container for mixing the powder. To prevent lumps add the powder to a small amount of water, continue to add powder and mix until a creamy consistency is achieved.

Mix paste 1

To check the consistency, get a small amount on the filling knife and holding the knife vertically over the mixing container, see if any paste falls off. If any paste falls back into the container, then add a little more powder.

Small crack

This small crack needs repairing, otherwise it will show through the new wallpaper. It is quicker to use a powder or a tub of ready mixed filler.

Large hole

This sort of damage, where a piece of plaster has broken away leaving a large hole, needs to filled using a powder or a tub of ready mixed paste.
