What you'll need:
- Filler
- Wire mesh
- String
- Wood or pencils
- A wet cloth
- Sanding paper
- Paint
Step 1: Repair the hole
The way you repair the hole will depend on how big it is.
Small holes
Small holes and knocks can be sorted with an application of filler.
- Scrape around the inside edge of the hole to remove any loose plaster.
- Dampen the area with a wet cloth.
- Fill the hole with the patching material and leave to dry for several hours.
- Once dry, sand the area flush with the wall.
Large holes
- Start by preparing the area as you would with a smaller hole.
- Get a piece of wire mesh larger than the hole and thread a length of string or wire through the centre.
- Place the mesh inside the hole and use the wire to pull it against the inside.
- To keep the mesh in place use a thin piece of wood longer than the width of the hole (paint stirrers or pencils work well) and twist the string securely around it to pull the mesh backing tight against the opening.
Step 2: Re-Plaster
- Wipe the mesh and inside of the hole lightly with a wet cloth.
- Apply the first coat of plaster, forcing it through the mesh and covering the edges of the hole to anchor it.
- Allow the first layer to dry.
- Untwist the string and remove the pencil before applying the second coat to fill in the hole completely.
- Allow the area to dry.
- Sand the area flat.
- Prime and paint the area.
