1) Prepare the Area:

Before starting, make sure the area is clean and free of any debris.

Clean the Tiles: Wash the tiled area with a mild detergent to remove dirt, grease, or soap scum. Allow it to dry completely.
Protect Surrounding Surfaces: Cover areas you don’t want to get dirty or damaged, like countertops or nearby floors, with a drop cloth or plastic sheeting.

Removing the old, damaged grout is essential to make room for the new grout.

Choose a Grout Removal Tool: Use a manual grout saw for small areas or delicate tiles, or an oscillating multi-tool with a grout removal blade for larger areas.
Remove the Grout: Carefully scrape out the old grout, holding the tool at a slight angle and applying steady pressure. Aim to remove grout to at least half the depth of the tile to ensure the new grout adheres properly.
- Tip: Work slowly and carefully to avoid damaging the edges of the tiles. Wear safety goggles, gloves, and a dust mask to protect yourself from debris and dust.

Once the old grout is removed, clean the spaces between the tiles.

Vacuum the Debris: Use a vacuum cleaner to remove any dust or loose particles from the gaps. A small brush can also help clean out stubborn debris.
Wipe with a Damp Cloth: Run a damp cloth over the tile surface to remove any remaining dust or residue.

If you’re using powdered grout, mix it according to the manufacturer’s instructions.

Mix Grout: In a bucket, combine the grout powder with water, adding small amounts until it reaches the consistency of smooth peanut butter. Be sure to mix thoroughly to eliminate any lumps.
- Tip: Let the grout mixture sit for 5-10 minutes (a process called slaking), then stir again before applying.

Now it’s time to apply the new grout to the joints between the tiles.

Use a Grout Float: Hold the grout float at a 45-degree angle and spread the grout over the tiles, pressing it firmly into the gaps. Work in small sections, moving diagonally across the tiles to ensure even application.
Fill All Gaps: Make sure all gaps are completely filled with grout. Remove excess grout from the tile surface with the edge of the grout float.

After applying the grout, you’ll need to clean the excess grout from the tiles.

Wait for Grout to Set: Let the grout set for about 10-15 minutes (or as recommended by the manufacturer). It should start to harden but still be workable.
Wipe with a Damp Sponge: Use a damp sponge to gently wipe away excess grout from the tile surface. Rinse the sponge frequently and change the water as needed. Avoid pressing too hard, which could remove grout from the gaps.
Final Cleanup: After the initial wipe, let the grout cure for another 15-30 minutes, then wipe again with a clean, damp sponge to remove any remaining haze from the tiles.

Allow the grout to cure fully.

Drying Time: Let the grout cure for at least 24-48 hours, depending on the manufacturer’s recommendations and humidity levels in your home.
Avoid Getting Wet: Ensure the tiled area remains dry during this curing period.

Sealing the grout helps protect it from moisture, stains, and mold growth.

Apply Grout Sealer: After the grout has fully cured, apply a grout sealer according to the product instructions. Use a small brush or applicator bottle to carefully apply the sealer to the grout lines.
Wipe Excess Sealer: Wipe away any excess sealer from the tiles with a clean cloth.

Make sure everything looks good and tidy up the workspace.

Inspect the Grout: Check for any spots where the grout might be uneven or missing. Touch up as necessary.
Clean the Area: Remove any protective coverings and clean the surrounding area to reveal your refreshed, clean tiled surface.
