Project Steps

  • Step 1: Fixing small holes
  • Step 2: Fixing large holes

Project Checklist


  • Drop sheet
  • Stanley knife
  • Stripping knife
  • Masking tape
  • 180 grit sandpaper
  • Plasterboard off-cut
  • Plaster filler
  • Wire
  • Plastic take away lid
  • Soudal Fix All adhesive and sealant

Step 1

Small holes are an easy fix. Chip off any excess plaster then dampen the whole and the surrounding surface. Fill the whole with plaster filler and leave overnight. Simply sand back and paint over.

Step 2

Larger holes are a bit trickier, but you can still fix it yourself.

Cut the hole as square as possible with a saw or Stanley knife. A bigger hole is going to need some backing to give the filler something to stick to. Using a plastic lid that is bigger than the gap in the wall, drill 2 holes into it, loop wire through use an adhesive sealant around the rim of the lid. Pull the wire tight so the lid is flush to the inside of the wall. Twist the wire around a pencil to hold it in place. Apply the filler around the wire, and once that's dry snip off the wire and apply the final filling layer. Sand back and paint over.
