Project Overview

Repairing holes is a cost effective way to improve the look of any plaster wall. We show you how to reinforce and patch the hole properly. You will also learn how to prepare the hole and the surrounding surface to help get the best results.
Continue to step-by-step instructions

Step by Step Instructions

1 Repair the hole in the wall with plaster
2 Apply a second coat of plaster to the hole in the wall
  • Step 1. Repair the hole in the wall with plaster

    Use the handle of your putty knife to tap the edges of your hole down. Then scrape around the edges of the hole with your paint scrapper to remove any flaky paint. Fill the hole with plaster compound and sand the surrounding paint to roughen it up. Now reinforce the hole with pieces of jointing tape, cover the tape with a bit more compound and leave it to dry.
  • Step 2. Apply a second coat of plaster to the hole in the wall

    Once the first coat of plaster is dry, give it a light hand sand and dust the surface clean with a rag. Then apply a slightly wider second coat of plaster and flatten it out with the blade of the paint scraper. Once the second coat is dry, smooth it out with another light hand sand, dust the surface clean and you are ready for painting.

Health & Safety

Please make sure you use all equipment appropriately and safely when following the advice in these D.I.Y. videos. You need to be familiar with how to use equipment safely and follow the instructions that came with the equipment. If you are unsure, you may feel it is safest to consult an expert, such as the manufacturer or an expert Bunnings Team Member.

Grave health hazards are linked to asbestos, which may be in homes built up to 1990. Health hazards may result from exposure to lead-based paints in older materials and copper chromium arsenic (CCA) treated timber. For information on the dangers of asbestos, lead-based paint and CCA treated timber and tips for dealing with these materials contact your local council's Environmental Health Officer or visit our Health & Safety page. You can also use a simple test kit from Bunnings to indicate the presence of lead-based paint.
