Re-grouting Tile: A Comprehensive Guide to Refreshing Your Tiled Surface

Re-grouting tile is an effective way to refresh the appearance of your tiled surfaces and prolong their lifespan. This comprehensive guide will walk you through the process of removing old grout and applying new grout, ensuring a professional-looking result. With the right tools and techniques, you can rejuvenate your tiled surfaces and improve the overall look of your home.

Step 1: Gather Necessary Tools and Materials

Before starting, ensure you have the following tools and materials:

Grout removal tool (manual or power)
Vacuum cleaner or shop vac
New grout (choose the right type and color for your tile)
Grout float
Rubber gloves
Safety glasses
Dust mask
Step 2: Prepare the Tiled Surface

Clean the tiled surface, removing any dirt, debris, or soap scum. This will allow you to better assess the condition of the existing grout and help the new grout adhere properly.

Step 3: Remove Old Grout

Put on your safety glasses and dust mask. Use a manual grout removal tool, such as a grout saw or scraper, or a power tool with a grout removal attachment to carefully remove the old grout between the tiles. Be cautious not to chip or damage the tiles during this process. Remove the grout to a depth of at least 1/8 inch to ensure proper adhesion of the new grout.

Step 4: Clean the Grout Joints

Once the old grout is removed, vacuum the grout joints to remove any remaining debris. You may also need to use a stiff brush to clean out any stubborn grout residue. Ensure the grout joints are clean and dry before proceeding.

Step 5: Mix the New Grout

Follow the manufacturer’s instructions to mix the new grout in a bucket. The consistency should be similar to peanut butter or toothpaste, making it easy to spread and work into the grout joints. Allow the grout to sit for a few minutes (known as “slaking”) to ensure proper hydration and consistency.

Step 6: Apply the New Grout

Wearing rubber gloves, scoop some grout onto a grout float and press it firmly into the grout joints. Work at a 45-degree angle to the tiles, ensuring the grout fills the joints completely and evenly. Use the edge of the grout float to remove any excess grout from the tile surface.

Step 7: Clean the Tile Surface

Allow the grout to set for approximately 15-30 minutes (or as directed by the manufacturer) before cleaning the tile surface. Using a damp sponge, gently wipe the tiles in a diagonal motion to remove any grout residue. Rinse the sponge frequently in clean water to avoid smearing grout back onto the tiles. Be cautious not to remove too much grout from the joints while cleaning.

Step 8: Cure the Grout

Allow the grout to cure for the recommended time specified by the manufacturer (typically 24-72 hours) before exposing it to moisture or heavy foot traffic. Keep the tiled surface clean and dry during this time to ensure proper curing.

Step 9: Seal the Grout (Optional)

If you’re using a cement-based grout, you may want to apply a grout sealer after the grout has fully cured. This will help protect the grout from stains and moisture damage. Follow the manufacturer’s instructions for proper sealer application and drying time.

Step 10: Finishing Touches

Once the grout has cured and, if applicable, the sealer has dried, give the tiled surface a final cleaning. Remove any remaining grout haze or residue using a clean, damp sponge or cloth. Inspect the grout lines for any imperfections or areas that may need touch-ups. If necessary, use a small amount of grout to fill any gaps or voids, and clean the surface again.

Step 11: Maintenance and Care

To prolong the life of your newly re-grouted tile, practice proper maintenance and care. Regularly clean the tiled surface with a mild, non-abrasive cleaner to prevent dirt and grime buildup. Avoid using harsh chemicals or abrasive tools that can damage the grout or tile. Additionally, promptly address any water leaks or moisture issues to prevent grout deterioration or mold growth.


Re-grouting your tile is an effective and cost-efficient way to refresh and maintain the appearance of your tiled surfaces. This comprehensive guide provides step-by-step instructions on how to remove old grout and apply new grout for a professional result. By following these steps and using the right tools and techniques, you can successfully complete this DIY project and enjoy the benefits of a refreshed and revitalized tiled surface in your home.
