- Grout removal tool: A grout saw or a multi-tool with a grout removal attachment
- Bucket: For mixing grout and water
- Grout remover: A chemical solution or a manual tool for removing old grout

Step 1: Prepare the Area
- Clear the area: Remove all furniture and objects from the room.
- Protect surrounding areas: Cover any surfaces that might be affected by dust and debris with plastic sheeting.
Step 2: Remove the Old Grout
- Choose your method: You can use a grout saw, a multi-tool, or a chemical grout remover.
- Use a grout saw: Make small, shallow cuts along the grout lines, then use the saw to remove the grout.
- Use a multi-tool: Attach a grout removal blade to the multi-tool and carefully remove the grout.
- Use a chemical grout remover: Follow the instructions on the product label carefully. Apply the remover to the grout, let it sit for the recommended time, and then use a scraper to remove the softened grout.
- Remove stubborn grout: If some grout remains, you can use a chisel and hammer to break it up. Be careful not to damage the tiles.
- Clean the area: Vacuum up the old grout and dust thoroughly.
Step 3: Clean and Prepare the Grout Lines
- Clean the grout lines: Use a damp cloth to wipe down the grout lines and remove any remaining debris.
- Let the lines dry completely: This is crucial for the new grout to adhere properly.
Step 4: Apply New Grout
- Mix the new grout: Follow the instructions on the package. Do not mix too much at once.
- Apply the grout: Use a grout float to apply the grout to the grout lines, pressing it firmly against the tiles.
- Clean the excess grout: Use a damp sponge to remove excess grout from the tile surfaces.
- Let the grout dry: Allow the grout to dry completely according to the manufacturer's instructions.
Step 5: Seal the Grout
- Apply grout sealer: Use a brush to apply the sealer to the grout lines.
- Let the sealer dry: Allow the sealer to dry completely before walking on the tiles.
Tips
- Wear protective gear: Always wear gloves, eye protection, and a dust mask when working with grout.
- Use a light touch: Don’t press too hard when removing old grout or applying new grout. This can damage the tile.
- Work in small sections: It's easier to manage the project by working in small areas.
- Practice on a scrap tile: Test out your grout removal and application techniques on a scrap tile before working on your floor.
