Things You'll Need:
- Ceramic-tile adhesive
- Thin-set mortar
- Notched trowel
- Tile spacers
- Miter saw
- Diamond blade
- Grout
- Bucket
- Rubber float
- Damp sponge
- Grout sealer
-
Step 1
Sweep and mop the existing ceramic tile floor and check for any loose tiles. Glue loose tiles down with ceramic-tile adhesive, and allow the adhesive to dry overnight.
-
Step 2
Starting at one side of the room, spread thin-set mortar approximately one-half inch thick with a notched trowel. Spread enough mortar to cover three to five- square feet, then comb the mortar with the notched trowel to create grooves in the mortar.
-
Step 3
Press the ceramic tiles into the mortar and use tile spacers to create equal distances between all tiles. Work methodically in rows, lining each tile up with previously placed tiles to maintain consistent rows.
-
Step 4
Continue to spread mortar and place the tiles until you've covered the entire floor. Cut tiles to fit as needed with a miter saw equipped with a diamond blade.
-
Step 5
Prepare grout in a large bucket according to the package directions.
-
Step 6
Spread the grout over the tiled area with a rubber float, making sure that the grout fills all of the crevices between the ceramic tiles. Gently wipe excess grout away from the face of the tiles with a damp sponge as you work.
-
Step 7
Allow the grout to cure for one to two weeks before applying a grout sealer to prevent stains.
