How To Repair Tile Grout In Shower

Tile grout is meant to keep water from seeping into the walls behind your shower, and it can also be a breeding ground for mold and mildew if it's not properly maintained. Grout can crack, chip, or become discoloured over time, but it's easy to repair with a few simple tools and materials. Here's how to do it:

Step 1: Clean the Grout

Before you can repair the grout, you need to clean it. This will remove any dirt, grime, or mildew that could interfere with the repair. You can use a commercial grout cleaner or a mixture of 1 part white vinegar to 1 part water.

Step 2: Remove the Old Grout

If the grout is cracked or chipped, you'll need to remove it before you can apply new grout. You can use a grout saw or a utility knife to score the old grout and then use a hammer and chisel to break it up.

Step 3: Apply New Grout

Once you've removed the old grout, you can apply new grout. Be sure to use a grout that is specifically designed for use in showers.

To apply the grout, use a grout float or a sponge. Work the grout into the joints between the tiles, and then smooth it out with a damp sponge.

Step 4: Seal the Grout

Once the grout has dried, you need to seal it to protect it from water and stains. You can use a commercial grout sealer or a mixture of 1 part white vinegar to 1 part water.

To apply the sealer, use a brush or a sponge. Work the sealer into the grout joints, and then allow it to dry.
