Preparation is key to a smooth tile regrouting job. Before you start, make sure you have all the gear on hand, including protective goggles or a face mask, a grout removal tool (like a grout saw or utility knife), a rubber grout float, quality grout, a bucket, sponge, vacuum or brush and paper towels. The right tools not only make the job faster but help you achieve a cleaner, professional finish.

Begin by removing the old grout from the joints between your tiles. Use a grout saw or utility knife to gently scrape out the worn or cracked grout, taking care not to chip or damage the tiles. Working methodically along each grout line ensures the new grout has a clean surface to adhere to, this step is crucial for long-lasting results.

Once the old grout is removed, it’s time to clean up! Brush out any dust and debris from the grout lines and vacuum the area to remove loose particles. A spotless workspace ensures your new grout bonds properly to the tile edges and fills the joints evenly, a key factor for strong, durable grout lines.

Mix your new grout according to the manufacturer’s instructions until it reaches a smooth, toothpaste-like consistency. Using a rubber grout float, press the grout into the joints at a 45-degree angle, working diagonally across the tiles. This motion forces the grout into every gap and reduces air pockets. Don’t worry about creating a little mess, that’s normal and easy to clean up later.

After applying grout, wait about 10–15 minutes to let it begin curing, then wipe away excess with a slightly damp sponge. Rinse your sponge frequently and work in gentle, circular motions until tiles are clean and grout lines are smooth. Once everything is clean and dry, apply a quality grout sealer to protect against stains, moisture and mould, keeping your tile joints looking fresh longer.
