What You’ll Need
- Grout cleaner
- Grout saw
- New grout mix
- Grout float
- Sponge
- Grout sealer
- Caulk gun (for silicone grout sealer)
Step 1: Preparing the Floor
Start by thoroughly cleaning the floor using a grout cleaner. This will remove any dirt, grease, or debris that could interfere with the new grout adhering properly. Follow the instructions on the cleaner, and ensure the floor is completely dry before moving on to the next step.
Step 2: Removing Old Grout
Using a grout saw, carefully remove the old grout. Be cautious not to scratch or damage the surrounding tiles. Create a groove by lightly sawing into the grout, and then scrape it out using the saw’s flat edge. Remove all the old grout until you reach the tile surface. Clean any dust or debris left from the removal process.
Step 3: Mixing and Applying New Grout
Prepare the new grout mix following the manufacturer’s instructions. Mix it to a consistency similar to peanut butter. Using a grout float, press the new grout into the gaps between the tiles, holding the float at a 45-degree angle. Work in small sections, ensuring the grout fills all gaps completely. Wipe away excess grout using the edge of the float.
Step 4: Cleaning the Tiles
Once you have applied the grout, wait for about 15 minutes to let it set. Then, with a damp sponge, gently wipe the tiles to remove any grout residue. Rinse and wring the sponge frequently to avoid spreading grout on the tiles. Continue this process until the tiles are clean and excess grout is removed.
Step 5: Sealing the Grout
To protect your newly applied grout, it’s important to seal it. Choose a grout sealer appropriate for your tile type (porous or non-porous). If using a liquid sealer, apply it generously over the grout lines using a small brush or sponge. For silicone-based sealers, load it into a caulk gun and carefully apply a thin, even layer. Allow the sealer to dry according to the manufacturer’s instructions.
Renewing floor grout is a simple and effective way to transform the look of your floors. By following this step-by-step guide, you can easily achieve professional-looking results on your own. Remember to clean the floor thoroughly, remove old grout carefully, apply new grout evenly, clean the tiles, and finally seal the grout to maintain its pristine appearance. Enjoy your refreshed and revitalized floors.
