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.
For small areas, a handheld grout saw is often sufficient. It’s easy to control and ideal for precision work. However, if you're working on a larger area or have stubborn grout, the best grout removal tool will be a multi-tool with a diamond blade attachment which will speed up the process and reduce strain on your hands.
2
Start removing the grout
Position your grout saw over the grout line and apply firm, steady pressure. Move the tool back and forth along the grout line. Take your time to carefully remove grout from tiles for the best results without damaging or scratching the tiles.
3
Avoid going too deep
When working in bathrooms or other wet areas, it’s crucial to take care not to compromise the waterproofing membrane beneath the tiles. This layer is essential for preventing water from seeping through and causing damage to the underlying structure, such as the subfloor or walls.
4
Clear away the dust
As you work, the grout will grind away and produce dust. Regularly use a vacuum or brush to clear away the debris so you can clearly see your progress and avoid any build-up in the grout lines.
5
Finish the removal
Once you’ve finished, it’s important to clean the grout dust or debris left behind. Use a damp microfibre cloth to gently wipe down the tiles and grout lines, ensuring the surface is clean and free of dust. This step is essential to ensure proper adhesion when applying new grout or undertaking further renovations. Once the area is clean and dry, you’re ready to prepare for regrouting or other updates to your tiles.
