How To Repair Grout Between Floor Tiles

Over time, grout between floor tiles can become discoloured, cracked, or missing altogether. This can not only be unsightly, but it can also allow water and dirt to seep into the subfloor, causing further damage. Fortunately, repairing grout is a relatively simple and inexpensive task that can be completed in a few hours.

Before you begin, you will need to gather the following materials:

Grout saw or utility knife
Grout sponge or brush
Grout
Grout float or trowel
Bucket of water
Clean cloths

Once you have gathered your materials, you can begin the repair process by following these steps:

Remove the old grout. Using a grout saw or utility knife, carefully score the old grout along the edges of the tiles. Be careful not to damage the tiles themselves. Once you have scored the grout, use a grout sponge or brush to remove the old grout.
Clean the area. Once the old grout has been removed, use a damp cloth to clean the area thoroughly. This will remove any dust or debris that could interfere with the new grout.
Apply the new grout. Using a grout float or trowel, apply the new grout to the area. Be sure to press the grout firmly into the joints between the tiles. Once the grout has been applied, use a damp sponge to smooth the grout and remove any excess.
Let the grout dry. Allow the grout to dry for at least 24 hours before walking on it or cleaning it.

By following these steps, you can easily repair the grout between your floor tiles, restoring them to their original beauty and preventing further damage.
