-
Step 1
Choose a grout color. If you are regrouting an entire bathroom, choose a color that matches the tile. For small jobs, match the grout color with the existing grout.
-
Step 2
Scrub the tiles and grout with a household cleaning solution.
-
Step 3
Saw along the grout lines with a grout saw or small knife that cuts into narrow spaces.
-
Step 4
Remove the remaining grout with a chisel or utility knife.
-
Step 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.
-
Step 6
Clean the tile. Remove soap scum and dirt. Any household cleaner designed to remove soap scum is perfect for the job.
-
Step 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.
-
Step 2
Spread the grout over the tile and smooth it out with a grout float. Angle the top of the float to 30 degrees.
-
Step 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.
-
Step 4
Run the float across the top of the tiles to remove excess grout.
-
Step 5
Wait five to ten minutes. Wet a sponge with water and wipe over the top of the tiles to clean any leftover grout.
-
Step 6
Cure the grout for at least three days.
-
Step 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.
