How to remove grout

Cutting grout between tiles using a multi-tool with a grout removal blade

Overview

If you have grout that is chipping or discoloured, you might need to remove it. We show you everything you need to do the job. You will also see what tools are available to make it a bit easier.

Steps

1Use the multi-tool to remove grout

Sweep away any loose debris or dirt using the dustpan and brush. Then use the multi-tool to cut into the grout. You might be tempted to push down on the tool as you cut. But it works much better if you let the tool do the work for you. Stop every so often to sweep the dust away so you can see what you are doing.

2Use the grout saw to remove grout

Some areas of grout will be difficult to reach with the multi-tool. This is where the grout saw comes in handy. It lets you work up close to the edges without damaging the tiles. Like with the multi-tool, stop every so often to sweep the dust away so you can see what you are doing.

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.
