It’s really easy to remove the old tile and replace it with a brand new one, restoring your floor back to its former glory.
Remove old grout
To do this manually use a hand tool called a “grout removal tool” and simply scour out the grout. You can also use a multi tool with a grout removal blade - place the blade in between the tiles and gently run it along the grout line until the grout is completely removed. Be really careful and work slowly as it is easy to get over enthusiastic and slip up damaging the surrounding tiles.
Remove the damaged tile
If the tile is fixed to the floor start by hitting the tile with a hammer to loosen it up. If a section of the tile breaks off you can use a cold chisel to hammer under the rest of the tile. When doing this always start from the centre of the tile and work towards the outside to ensure you don’t chip surrounding tiles. If the tile is on a wall we don’t recommended you hit it with a hammer, as you could damage the wall board behind the tile. If the tile is on a wall (and not in a wet area), you can use a drill and tile bit to drill a couple of holes into the tile to help it break out of the space. You can also use this method on floor tiles (but again not in a wet area).
Once the tile is removed use a paint scraper to get rid of the remaining adhesive from the surface. You could also use a multi tool with a scraper blade. If tile is in a we area best call in a professional to prepare this.
Replace the tile
If you do not have a spare tile you will have to take a sample of your tile into store to purchase a new one. Measure the size of the tile you need carefully before heading in store. Be aware that tile colours may vary from batch to batch and it may not be the exactly same colour as yours. To replace a tile smaller than 600 x 600mm, apply your tile adhesive to the back of the tile using the notched trowel and gently push the tile in place. To replace a larger format tile, apply the adhesive to the floor first.
Ensure that all the corners are flush with the surrounding tiles. Insert the tile spaces into the corners so it lines up with the other tiles and leave to set overnight.
Grout the tile
When the tile is firmly secured in place remove the spacers. Mix up your grout following the instructions on the bag. Using a grout float wipe across the tile on a 45 angle, forcing the grout into the gap. Once you have sufficient grout between the tiles use a damp sponge to remove any excess grout. When the grout is dry, use a cloth to remove any grout on the tile to leave it looking nice and clean. If the tile is around the outside of a room, ensure you run a bead of silicone around the edge.
