This blog will show you how to repair grout tiles with the best techniques.

List of Things You’ll Need for Regrouting

If your grout is starting to show signs of wear and tear or is cracked or damaged, you can repair it without removing the old grout entirely. This can save you time and money, and it can also be less disruptive to your home.

This is a list of things that you’ll need for easy grout repair:

  • Sponge
  • Bucket 
  • Bleach or grout cleaner 
  • Stiff-bristled brush 
  • Grout saw (optional) 
  • Vacuum with soft brush attachment (optional) 
  • Grout float    
  • Trowel     
  • Caulking gun (optional) 
  • Silicone caulk (optional)     
  • Clean rags or cheesecloth

How to Repair a Grout Without Removing the Old One     

First things first, you need to gather all of the materials that are listed above. Once you have everything, you’re ready to start repairing your grout.

1. Clean the Surface

Use a sponge and bucket full of warm water with either bleach or a grout cleaner. Gently scrub the entire surface, paying close attention to problem areas. Rinse thoroughly and allow to dry completely.

2. Prep Problem Areas

If your grout is cracked or missing in spots, you’ll need to do some prep work before you fix the grout between tiles. 

To repair cracks, use a caulking gun and silicone caulk designed for wet areas. Fill cracks flush with the tile surface or slightly below.

For missing grout, use a grout saw or similar tool to remove any loose debris from joints. Vacuum debris from the area using a soft brush attachment.

3. Mix New Grout

Follow the manufacturer’s instructions for mixing ratio and curing time. Pour the desired amount of mixed grout into a plastic container with a wide opening.

4. Apply New Grout

First, apply new grout to horizontal joints using a rubber float at about a 45° angle.

Starting at the back corner of the area, push the float diagonally across each joint to force the grout into voids; hold the float almost parallel with tiles during final strokes to discourage voids from forming beneath the tiles’ edges.

5. Remove Excess Grout

Wipe tile surfaces clean with a damp sponge; frequently rinse in a bucket of clean water and squeeze the sponge dry often.

6. Cure New Grout

Allow new grout to set following the manufacturer’s instructions before being exposed to foot traffic.

7. Seal New Grout

After the curing period has elapsed and the area is completely dry, apply two coats of high-quality sealer designed for ceramic tile and grouted surfaces using a clean cloth following the manufacturer’s instructions.
