How to re-grout tiles

February 3, 2014

Have you started to discover the grout around your tiles is crumbling away or is just not there due to wear and tear? Not only does it look horrible is will be allowing moisture into your walls and floor which over time will loosen and lift the tiles. If this is the case then it’s time to re-grout. Here are some tips on how to do it yourself, however if you would prefer a professional to assist or perhaps its time to renovate and replace with a more modern tile, Andersens can help.


Preparing the Tile

  1. Choose a grout colour. If you are re-grouting an entire bathroom, choose a colour that matches the tile. For small jobs, match the grout colour with the existing grout.
  2. Scrub the tiles and grout with a household cleaning solution
  3. Saw along the grout lines with a grout saw or small knife that cuts into narrow spaces.
  4.  Remove the remaining grout with a chisel or utility knife.
  5. Vacuum out the leftover chunks or debris from the spaces around the tile. If any of the tiles need to be replaced, replace them now.
  6. Clean the tile. Remove soap scum and dirt. Any household cleaner designed to remove soap scum is perfect for the job.

  1. Mix the grout. Grout is sold pre-mixed or dry. If you need to mix the grout, read the directions on the package and follow the instructions. Latex-modified grout is more water resistant and does not crack over time.
  2. Spread the grout over the tile and smooth it out with a grout float. Angle the top of the float to 30 degrees.
  3. Use the float to press the grout into the empty spaces between the tiles. When the grout becomes hard to push down, the spaces are full.
  4. Run the float across the top of the tiles to remove excess grout.
  5. Wait five to ten minutes. Wet a sponge with water and wipe over the top of the tiles to clean any leftover grout.
  6. Cure the grout for at least three days.
  7. Seal the grout with a grout sealer. This keeps water and mildew out of the grout. If using ceramic tiles, use a silicone or water-based grout sealer. Brush it along the joints between the tiles. Wipe excess sealant off the surface of the tiles. If you have porous tiles, use an acrylic top-coat and seal the entire surface of the tile.
