When mixing the grout, add the water first and then the powder to ensure a thorough mix with no lumps. Follow the instructions on your packet and mix to a thick paste-like consistency.
Apply the grout to the tiles using a trowel. The size of your tiles will determine the size of the trowel to use. For tiles smaller than 300x300mm you can use an 8mm trowel. For larger tiles you’ll need a 10mm or 12mm trowel.
Push the grout into the joints and compress by wiping over at an angle across the joints. Do not apply grout to the corners where walls meet floors and where two walls meet. You will need to apply silicone here.
First, allow the grout to dry and for a film to set on the face of the tiles. This should only take about an hour.
Then remove the excess grout.
Clean up with a slightly damp sponge. Don’t wash the floor or get it overly wet. The trick here is to lift the film off the tiles without wetting the actual grouted joint.
Keep rinsing your sponge as you go.
After most of the grout has been removed from the tiles, give them another once-over with the damp sponge. Then buff over the tiles with clean, dry cloths and a doodle bug.
Once the tiles are completely clean, we recommend applying a grout sealer.
