How to Re-Grout Tiles

Grout is the filler between tiles to hold them in place. Grout acts as a barrier against water, mildew and mold that can develop in the tile and gives tile strength. Grout is a mixture of sand, water and cement. Grout can come in a wide array of colors.

Difficulty: Moderate

Instructions

Things You'll Need:

• Grout Commercial grout cleaner Grout saw Damp cloth Grout float Squeegee or grout sponge Grout sealer

1. If you have an existing color that you need to use, take a small piece to the store with you. Use sand grout if the space between the tile is larger than 1/8 of an inch.

2. Clean the grout with a commercial grout cleaner and allow to dry. Use the grout saw to break up cracked grout and wipe up the debris. Using a damp cloth, moisten the spaces where the grout is going to be applied.

3. Mix the grout specified on the bottle's directions. Apply the grout to the empty spaces with the grout float. Go over the space with the squeegee or sponge to remove grout on the tiles.

4. Let the grout dry based on the manufacture directions. Check to see if the grout has shrunk from drying, if so, apply more grout.

5. Seal the groat with grout sealant, then wipe off excess sealant with a damp cloth after it has dried.

Tips & Warnings

• Smooth the grout using a wet finger after each application.
• Applying sand grout to marble tile will scratch your floors -- use non-sand grout instead.
