We’ve been on a bit of a kick with tile lately (how to clean grout, unexpected ways to use tile, and how to cut tile) so we figured why not keep it up right through December? 

We can imagine the sense of accomplishment and admiration you felt when you first installed your tile. It all looks so sleek and seamless, the grout lines forming a definitive line between each of the gorgeous tiles. And yet, over time, after years of wear and tear, the grout lines have really started to detract from the overall look. That is exactly why we are walking you through exactly how to regrout your tile. Our guess is that by the end of this article, you’ll be pretty shocked by just how easy the process is.

Step #1: Prep your space

The first step is an important one and it involves gathering your supplies. You will need: 

Step #2: Remove the old grout

Use the utility knife or grout saw and the chisel to tap along the old grout lines and chisel away the top layer of the grout. Be careful not to hit the tile.

Step #3: Clean the old grout lines and pre-seal

Remove the old grout from your working space so you can start work on a clean surface. Then use the pre-grouting tile sealer to protect the tiles and make sure everything remains smooth while you work around them. 

Step #4: Add the new grout

Mix together the grout in a bucket according to the manufacturer’s instructions and apply it between the tiles. Be sure to go over the same area a few times to really pack down the grout and eliminate air bubbles but don’t worry if you get it on the tiles; you’ll be able to go back and clean them.

Step #5: Clean the tile surface

This is where you’ll be removing the grout that you may have gotten on the surface of your tiles. No worries at all! Simply take the rubber grout float and move it diagonally across the tile’s surface to remove the excess grout. 

Step #6: Give the grout time to set

Once you’ve completed the first 5 steps, the tile will need about 10-15 minutes to set. Once it’s had that time, you can clean the surface of the grout using a slightly damp sponge. Allow the grout to dry for 24-36 hours for the best results.

Step #7: Caulk and seal the joints

To wrap up your project, go over the grout lines and caulk the gaps between the tiles. 

And finally, seal the grout lines with tile sealant to make sure your hard work stands the test of time.
