Give your bathroom or kitchen tiles a new lease of life by regrouting them. In this expert guide, we’ll show you exactly how to do it with video and step-by-step instructions.

Tiles are a great choice for splash zones in bathrooms and kitchens as they provide a practical yet stylish covering for your walls and floors. However, over time, they can suffer from mould and damage.

If your kitchen or bathroom tiles are looking a little tired and grubby, or you’re simply looking to replace a damaged tile, you’ll need to regrout. To find out how to do this, follow our video and step-by-step instructions below, part of our series of articles on simple “modern” fixes for your home.

For demonstration purposes, we used the Bordeaux blue flat gloss wall tile 200mm x 457mm in this video.

Here is how to regrout tiles

  1. Remove the old grout from all tiles you wish to regrout.

  2. With all of the old grout removed, take a damp sponge and wipe down the area. This will get rid of any remaining debris and dust that you may have missed.

  3. Which grout you use will depend on both the colour and the amount you need. If you’re applying grout to a small area, you can purchase ready-mixed tubs. However, the colour range of ready-mixed grout is limited so you may need to choose a powdered grout to mix yourself.

  4. Use a small trowel to apply grout along the lines you wish to fill.

  5. Using a grout float or spreader, push the grout into the lines. Place your spreader against the tile at an angle and sweep across the tile surface. This will move excess away from the line, leaving you a nice, neat edge.

  6. The grout finishing tool will give you a consistent, smooth grout line. Press the ball end into the line and gently run it across.

  7. Once the grout has set, a chalky film will appear over the tiled surface. To treat this, simply use the damp sponge once more to lift the residue.

  8. Buff the tiles with a dry cloth.

Congratulations, you have now regrouted your tiles.
