How to Regrout Countertops

New grout revives the look of your tile.

Countertop grout, especially if it is not sealed for protection, accumulates dirt, grime, stains and bacteria. Replace grout on countertops when stains become permanent, grout colors become dated or when grout chips, breaks or cracks. Grout comes in a wide range of color choices, so choose a color to coordinate with the existing tile. A do-it-yourselfer will complete this task with little trouble. Allow several hours for completion of this home improvement project.

Things You'll Need

• Flat-blade screwdriver
• Light hammer
• Grout float
• Paintbrush
• Grout sponge
• Grout sealer

Instructions

1. Remove the existing grout with a flat-blade screwdriver. Place the screwdriver in the center of the grout line and gently tap with a light hammer to crack and break the grout. Remove small, broken grout pieces as they become loose. Continue around each tile until all old grout has been chipped out of grout lines.

2. Scrape old grout off tile edges carefully, using a flat-blade screwdriver.

3. Brush out grout pieces and grout dust with a paintbrush.

4. Wipe the tiles with a damp rag to remove dust and the remaining grout particles.

5. Mix new grout according to the directions on the package.

6. Press grout forcefully into areas between tiles with a grout float. Use a flat grout float, rather than a lined grout float, for neater results.

7. Apply grout at a 30- to 45-degree angle. Watch the edges of the grout float to avoid scratching the tile surface.

8. Wet a grout sponge and squeeze out excess water.

9. Wipe the tiles and grout lines often to remove excess grout. Rinse the grout sponge after each pass. Allow the grout to dry.

10. Apply grout sealer according to the directions on the package.

Tips & Warnings

• Use sanded grout for tiles spaced greater than 1/8 inch apart. Use unsanded grout for tiles spaced less than 1/16 inch apart.

• Seal new grout to preserve its beauty and resist stains.

• Wear gloves and protective eyewear when removing existing grout. Wear rubber gloves when working with grout.
