How to Patch a Hole in the Wall (the Easy NZ Way)

Got a dent or hole in your wall? You don’t need to hire a tradie.

One of the easiest ways to fix it – without screws, backing blocks, or drama – is the California patch method.

🛠️ Here’s how it works:

🧱 Step 1: Get a plasterboard offcut

You can buy a cheap “handy panel” at Bunnings for small jobs – great to keep in your DIY stash.
👉 ProRoc 1195 x 595 x 10mm plasterboard

✂️ Step 2: Cut your patch

1. Cut a square/rectangle around the damaged area.
2. Cut a slightly larger patch out of your plasterboard.
3. Score and snap the edges of the patch but don’t cut all the way through – leave the paper face intact on the front.

This paper “flap” will act like built-in tape.

🪛 Step 3: Glue and mud it in

1. Apply joint compound around the hole.
2. Press the patch into place, using the paper flap as a smooth edge.
3. Feather out the joint compound over the area.
4. Let dry, sand, and do a second coat if needed.

👉 Use any all-purpose joint compound, like this one:
Westpac 0.83L All Purpose Joint Compound

This is one of the simplest ways to do small plaster repairs without messing around with backing pieces. Perfect if you’re prepping for an inspection, moving out of a rental, or just keeping the house tidy.
