Every plaster or gyprock wall from time to time is prone to the odd bump or knock or oops moments that can leave a small hole in wall.
I’ll show you how to fill a small to medium sized hole – the sort that might be the result of an misguide throw or a door handle being slammed open one too many times – with no mess and no fuss.
What you’ll need:
- CSR Multipurpose Joint Compound
- Putty knife or flexible filler blade
- Fibreglass mesh
- Fine sandpaper
- Clean wipe cloth
- Drop cloth
How to do the job:
1. Clean – Place your drop cloth down beneath the surface you’re working on to catch the plaster and dust 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 10mm in diameter with a cavity behind it will need bridging material. In this case it is, use some adhesive fiberglass mes. Peel away the backing and place a square over hole and make sure it stick by gently applying pressure and rubbing hand over mesh. Allow at least 20 to 30 mm around the outside edge of the hole.
3. Cover – apply a layer of CSR Multipurpose Joint Compound. Using spatula that’s on the lid, gently force some plaster 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 plaster across the area in multiple directions. Once the hole is covered, use a single downward stroke to remove any excess product.
Tip: there a couple of options when it come to drying you can leave it over night.
Use a heat gun and gentle go back and forth to spread heat over surface. do not let the surface heat up too much the goal here is warm not hot, use your hand to check heat if in doubt (gently).
4. Strengthen – Using fine sandpaper, lightly sand the area and spread a second layer of plaster 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.
