How to grout tiles

Freshly grouted white tiles

Overview

Grouting is the final step to complete your tiling project, giving your tiles a clean and professional finish. Whether you’re working on a splashback, a bathroom floor, or a kitchen wall, learning how to grout tiles properly will ensure a long-lasting and polished result.

Safety tip: Always wear the appropriate safety equipment (safety glasses, gloves, ear muffs and a mask, for example) and always follow the instructions for the product or equipment.

Steps

1Prepare the surface

Before you begin, make sure your tiles and grout lines are clean and free from dust and debris. A quick wipe with a damp cloth should do the trick. If there’s any excess tile glue in the grout lines, carefully scrape it out. This step ensures the grout adheres properly and results in a clean, even finish.

2Mix the grout

Following the instructions on the packaging, mix the grout with water in a bucket. Aim for a smooth, toothpaste-like consistency that is neither too thick nor too runny. Use the grout immediately to prevent it from setting in the bucket.

3Apply the grout

Using a grout float, press the grout into the gaps between the tiles. Hold the grout float at a 45-degree angle and work diagonally across the tiles to ensure the joints are fully filled. Rolling your wrist slightly as you work will help push the grout deeper into the gaps, creating a strong and secure bond.

Once all the joints are filled, use the edge of the grout float at a shallow angle to scrape off any excess grout from the tile surface. This step helps keep the tiles clean and makes the next stages of the process easier.

4Wipe away grout residue

After about 10–15 minutes, lightly dampen a sponge and gently wipe over the tiles to remove any grout residue. Use circular motions, being careful not to pull grout out of the joints. Rinse the sponge regularly for the best results. If you notice any areas that need additional grout, touch them up before moving on. As the grout begins to set, go back over the joints with a damp sponge to smooth them out. This step helps create a clean, professional finish and ensures the grout sits evenly between the tiles.

5Buff the tiles

Once the grout has fully dried (usually after 24 hours) use a soft cloth to buff the tiles and remove any remaining grout haze. This final touch will make your tiles shine and enhance the overall look of your project.

6Seal the grout

If you are tiling in an area exposed to moisture, such as a bathroom or kitchen, sealing the grout is a good idea. This helps prevent stains and mildew, keeping your grout looking fresh for longer. Follow the instructions on your chosen grout sealer and allow it to cure properly before using the area.

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.
