DIY Projects - Filling holes & 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.
Save some money and use an old margarine tub as a mixing bowl.

Using a piece of fine glass paper wrapped around a rubbing block, rub down the repair until it is level with the surrounding area. |
