Painting a wall with blue paint

Overview

Painting your walls can bring new life to a room. Just as important as choosing the right colour is preparing the walls. We'll show you a quick way to clean and prepare your walls so that the paint goes on easier and the finished job looks better.

Steps

1Clean your walls with sugar soap

Making sure your walls are properly clean will help the paint to stick better. A clean surface also stops stains and marks showing through the new paint. For a good clean you need to use sugar soap. Mix up the sugar soap in a bucket of water according to the instructions on the bottle. Put on your gloves and thoroughly wash the walls using the sugar soap mixture. Once you've cleaned the wall, dry the sugar soap off using a rag.

2Scrape cracked paint off the walls

After your walls have been cleaned and are dry, put on your safety glasses and dust mask and lay down a drop sheet near the wall. Use a paint scraper to remove any flaky and cracked paint from the wall. Use the ladder to reach spots higher up on the wall.

3Apply gap filler to any cracks

Mix the powdered gap filler in a bucket with some water until it's the consistency of toothpaste. Using your paint scraper, apply it to all of the cracks and chips on the wall, making sure to overfill them. When your gap filler is dry, use sandpaper on a hand sander for a smooth finish.

4Seal the gaps in the corners

Use a multi-purpose gap sealer and a caulking gun to fill the gaps in the corners of the walls. After applying the gap sealer, use a damp cloth to wipe off any excess. This will also make it smooth and push the filler it into the corners. You may need a second layer of gap filler to finish off. Now your walls are now ready to paint.

Health & Safety

Asbestos, lead-based paints and copper chromium arsenic (CCA) treated timber are health hazards you need to look out for when renovating older homes. These substances can easily be disturbed when renovating and exposure to them can cause a range of life-threatening diseases and conditions including cancer. 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.

When following our advice in our D.I.Y. videos, make sure you use all equipment, including PPE, safely by following the manufacturer’s instructions. Check that the equipment is suitable for the task and that PPE fits properly. If you are unsure, hire an expert to do the job or talk to a Bunnings Team Member.
