Why Do Grouts Get Damaged?


Grout is a cement-based mixture used to fill in the gaps between tiles.

At some point, every homeowner will have to deal with a cracked grout line. Whether from everyday wear and tear or accidentally dropping something heavy on the floor, dealing with a broken grout line is an inevitable part of home improvement.

When this happens, it’s important to repair the grout so that water doesn’t seep into the cracks and cause damage to your tile or underlying structure.

What You Will Need for This Task

Fixing cracked grout that has been fractured is not a difficult task. The truth is that you probably already have everything you need lying around the house to do this project. All you need is the following materials listed below, and you’ll be on your way to having brand-new grout lines in no time!

Here’s what you’ll need to fix a cracked grout line: 

  • Grout sealer (this is optional but will help prevent future cracks) 
  • Caulking gun 
  • Caulk 
  • Utility knife 
  • Mixing bowl 
  • Mixing spoon 
  • Rag or paper towel 
  • Bucket 
  • Water 

And now, it is time to get to work.

6 Steps to Repair Cracked Grouts

Step 1: Remove the Old Grout

You must first remove the old grout before you can begin fixing the damaged grout. Use a grout saw or rotary tool to remove the old grout. Wear goggles and gloves to protect your eyes and hands. Saw through the old grout slowly and gently, taking care not to damage the tile. Vacuum up any dust and debris once you’ve removed all of the old grout.

Step 2: Mix the New Grout

It’s time to mix up the new grout. Follow the manufacturer’s instructions since there is a determined mixing ratio according to the type of grout. Once the grout is mixed, it’s important to work quickly. If it gets too thick, add a little water and stir until it reaches the desired consistency.

Step 3: Apply the Grout

Using a rubber float or putty knife, apply the new grout to the cracks in your tile. Work quickly and evenly, filling cracks in grout lines without air pockets. Smooth the surface of the grout with the float as you go.

Step 4: Let It Set

Once you’ve applied all the new grout, let it set for at least 24 hours before exposing it to water or foot traffic. This will give the grout time to cure and set up properly. 

Step 5: Clean Up The Tile Surface

After the grant has had time to set, use a damp sponge or cloth to remove any excess grout from the tile’s surface. Be sure to rinse off your sponge or cloth frequently, so you don’t inadvertently scratch the tile surface while cleaning.
