How to Re-Grout Tile

At times there is a need to re-grout tiles, especially for common grout problems such as deep-seated dirt and stains, as well as cracked or damaged grout. Tile grout can easily be replaced. There's no need to re-tile the whole area when, with a little bit of elbow grease, you can use this simple re-grouting solution to make the tiles look new and attractive again.

Difficulty: Moderate

Instructions

Things You'll Need:

• Chisel or a screwdriver
• Hammer
• Circular saw (optional)
• Grout mixture
• Trowel
• Grout float
• Spatula
• Sponge
• Grout sealer
• Goggles

1. Wearing goggles, remove the damaged or stained grout using a chisel or a screwdriver and hammer. Hit the top of the chisel or screwdriver gently with a hammer. If you are planning on replacing a huge area of grout, use a circular saw starting from one end and going up to the other end. Make sure not to cut too deep. Measure the height of the tile and adjust the saw to desired height so as not to damage the surrounding tiles, sub floors (if re-grouting tiled floor), base counter (if re-grouting counter tops) and mortar.

2. Clean the area of dust and debris coming from the old grout using a wet sponge.

3. Mix the grout compound or mortar thoroughly. Remove lumps and mix until the consistency is that of peanut butter.

4. Apply the grout mixture by using a huge trowel or float. If you have a huge area to re-grout, get a big glob in order to cover a big area. Apply the grout in a diagonal motion, as if you are using a squeegee. Start by applying grout to a small area, then put as much coverage as possible when you feel that you are comfortable with the process. For a small project, instead of using a float, you can use a spatula or a small trowel to apply the grout mixture.

5. Immediately wipe the grouted area with wet sponge. Get a bucket of water and dip your sponge, wringing every now and then to remove the dirt.

6. Let dry overnight.

7. Apply grout sealer on the newly dried grout. This will protect the grout from stains.

Tips & Warnings

• If there are dried smudges of grout on the tile the next morning, remove by using a spatula or blade. Gently rub off the dried mortar to avoid scratching the surface of the tile.
• Use precaution when operating a circular saw; wear eye protection or goggles and work gloves.
