There are numerous causes for cracks and breaks in tile flooring. A floor that is properly installed by a certified professional should allow for a reasonable amount of expansion and contraction from the flooring. Wear and tear is the most common source of tile cracks, but a weak subfloor could be the issue. Ask a local professional to take a look at the structure of your floors if you are experiencing grout issues on continuous occasions.

Sanded v. Unsanded Grout
If the width of the grout lines on your floor are less than one-eight of an inch, you will need unsanded epoxy or latex grout. If the lines are wider than one-eighth, then you will need sanded grout. With marble tile floors unsanded epoxy or acrylic is used because sanded grout scratches the surface.

Match New Grout
Take a sample of the broken grout with you to the store. An attendant can help you match the shade and consistency.

Clean The Area
A mixture of white vinegar and water can be used to clean the damaged area.

Cut Grout
Use a grout saw to cut and remove the damaged grout from the floor. Be sure to read the saw instructions and familiarize yourself with the tool. Move the saw back and forth along the damaged area and cut out the grout. Be careful not to cause additional damage to the tile.

Clean
Use a damp paper towel to clean out the grout line. Limit the amount of excess water left in the lines. Don’t remove all of the liquid though, because slight dampness helps the grout to bind with the tile.

Prepare Grout
Follow the package directions for preparing the grout. Pay careful attention to the water amount because different types of grout require different amounts of water.

Apply Grout
Use a grout float to push the grout mixture into the joint of the floor. A craft stick can be used to smooth the joint.

Wipe Surface
Use a clean, damp sponge to wipe the surface of the surrounding tiles. The sponge should be rinsed frequently to prevent smearing onto connecting tiles. Follow the manufacturer’s directions for drying and be mindful of temperature and humidity, because they can affect the speed.

Clean Surface
Use a soft cloth the clean the surface of the tiles. If the dry cloth does not remove the haze, include a mixture of white vinegar and water. Apply the mixture with a sponge and use a dry cloth to wipe it.

Grout Sealer
Use a small paintbrush to apply grout sealer to the treated area. Follow the manufacturer’s instructions for application.
