Fixing Damaged Plaster

Fixing Damaged Plaster
Interior and exterior walls occasionally need a little repair work before repainting. Even the best maintained home will suffer the occasional dent. Fixing this before repainting helps ensure the best possible paint result.Some holes in walls are from removed fixings rather than accidental damage. It is not uncommon to find holes left from hooks that held a mirror or that secured a bookshelf or television. These will need to be filled if the furnishings are being removed.

Holes and cracks in walls can be repaired with plaster. It is best to repair this type of thing as soon as possible lest the damage grow worse over time.
  1. Clean the area around the hole or crack as any grease or dust can compromise the repair. Use sugar soap if available.
  2. If necessary, scrape around the hole or crack with a putty knife or paint scraper. Make sure the surface around the damaged area is flat. 
  3. Sand the area to roughen the surface.
  4. If the hole is larger than about 1 cm it will be difficult to keep the plaster in place. To prevent the plaster from falling into the hole put some fibreglass mesh over the space.
  5. Use some fast setting plaster like spakfilla. Only mix enough plaster to fill the hole. 
  6. Use a putty knife to apply the plaster, and flatten the surface to sit flat with the surrounding wall. 
  7. Some plasters will set quickly enough to be sanded after an hour. 
  8. Sand the plastered area flat. Using a flat block of wood behind the sandpaper will help keep the surface level.
  9. Vacuum the area to remove any dust.
  10. You can paint over the area once it is dry. If using oil based paints you should wait 24hours before painting as some oil paints will react with paster that is not completely dry.
