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

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. You can also use a simple test kit from Bunnings to indicate the presence of lead-based paint.
