How to Fix Grout

The grout between your tiles plays an important role in keeping your home looking good while strengthening the integrity of your floors and walls as well. Being that grout is often in places prone to collecting dirt, grime, germs, and a lot of traffic throughout the home, there may come a time when you notice a crack or break that requires attention.

Read on for the step-by-step guidance you need to DIY a grout repair.


For this project you will need:

  • New grout - make sure the color matches your current grout
  • White vinegar
  • Grout saw
  • Grout float
  • Sealant
  • Sponge

Step 1: Clean

The first and most simple step is to clean the area of broken grout you will be working on. You can do this with a white vinegar and water solution to break down any particularly tough grime and germs.

Step 2: Remove Damaged Area

A grout saw is attached to a small hand held device, much like a dremel. You can pick this tool up at the hardware store while buying the correct color grout, float, and sealant. Use this small saw to carefully chip away at the damaged grout, removing about ⅛ of an inch to make room for the new mixture to settle in. Once you’re satisfied, wipe away the excess dust.

Step 3: Apply the Grout

Take your sponge and wet the area you’re working on to begin. Then take a scoop of the new grout and, using the grout float, apply it to the gap between tiles. This will likely be a messy process, but don’t worry, you’ll be able to easily clean off the residue after it has dried. Be sure the whole gap is filled before using the float to scrape away extra material and create a nice grout line.

Step 4: Set and Clean

The grout will need about 30 minutes to fully set before you can touch it again. So, set the timer and take care of some other business while you wait. Once the time has passed, take a wet sponge and clean off any extra, dried grout on the surrounding tiles, making them clean once again!

Step 5: Sealant

If you chose a latex grout, you will want to apply a sealant after the dry time is complete. Grout sealer comes in a variety of application methods including spray bottles and brush-ons. Choose your preferred method and closely follow the instructions on the product for the best results.
