How to repair a hole in a plaster wall

Every plaster wall is prone to wear and tear over time, from scratches in the paint to ever-widening dents and holes.

In many cases, the longer you put off fixing up these areas, the worse they get.

We’ll show you how to fill a small to medium sized hole – the sort that might be the result of an errant hammer swing or a door handle being slammed open one too many times – with no mess and no fuss.

What you’ll need:

  • Selleys Spakfilla Rapid
  • Putty knife or flexible filler blade
  • Fibreglass mesh
  • Fine sandpaper
  • Clean wipe cloth
  • Drop cloth


1. Clean – Place your drop cloth down beneath the surface you’re working on and scrape around the inside edge of the hole with your putty knife to remove any excess plaster or debris. You may need to use the sandpaper to smooth out the edges. Wipe over the area with a clean cloth to remove dust from scraping.


2. Prepare – Any hole larger than 1cm in diameter with a cavity behind it will need bridging material. Peel away the backing and place a square of adhesive fibreglass mesh firmly over the hole. Allow at least 2-3cm around the outside edge of the hole.


3. Cover – apply a layer of Spakfilla Rapid. Using spatula that’s on the lid, gently force some Spakfilla through the holes in the mesh and make sure it completely covers the mesh square around the sides of the hole. For the best seal, use a putty knife or a flexible filling blade to take the Spakfilla across the area in multiple directions. Once the hole is covered, use a single downward stroke to remove any excess product.

Allow the Spakfilla to dry 30 minutes.

4. Strengthen – Using fine sandpaper, lightly sand the area and spread a second layer of Spakfilla over it. Depending on the size of the hole or if the mesh has been exposed when sanding, you may wish to repeat this process once more, after allowing a day for drying.


5. Once you have sanded back the final layer and brushed off any excess dust with a clean cloth, the seamlessly covered hole is ready to be painted over.
If you’re using oil based paints, wait for at least 24 hours.
