Fix A Hole In The Wall

Handyman Luke Van Dyck shows you how to repair a plasterboard hole.

You will need:

• A trowel for cement
• A block of wood a bit bigger than your hole you are repairing
• A sandpaper block and fine sandpaper.
• 3 screws
• Wood glue (Selley’s Liquid Nails) approx $4
• Cornice cement as your base coat plaster approx $21 (also known as gyprock patching cement)
• Plaster Filler Top Coat approx $12
• Matching paint for your wall colour – price varies


• Firstly remove dags from around the whole with a Stanley knife, working at a 45 degree angle.

• Start with a piece of timber as a backing plate – slightly bigger than the hole (if the hole, you can skip these steps and go straight to plastering). Put the screw in the centre and that will act as a handle as when fixed off into place.

• Glue either side of the timber before you insert it into the wall. Once the wood is in the hole, fix it in either side with a cordless drill. Get screw heads below the surface so when plastered over, there is a smooth surface on the finished wall.

• Once the wood is securely fixed off – undo the centre screw and you are ready to fill it with a base coat plaster. It is very important that you follow the instructions on the packet for the plaster.

• Plastering - First mix up some base coat. The trick is to keep the base coat below the surface of the hole. It’s a very hard compound, very hard to sand down.

• Allow base coat to dry 100% before applying a top coat. This usually takes about 4 hours on a dry summer’s day, but drying time will depend on the weather. For a very big hole, you may need to apply 2 coats of base.

• Once the base coat is dry – apply the top coat over the hole and spread it right out. The top coat is easy to sand to give that perfect finish. The plaster instructions will advise the drying time.

• Using a sanding block, keeping it flat on the wall, work in circular motions on the plastered hole and into the centre continually moving the sanding block to create an even surface.

• Put a sealing coat of paint over the patch, then two coats of matching paint.
