Easy Steps to Replacing Grout

A simple grout replacement is a job anyone can tackle. This step-by-step guide will give you the confidence to conquer any grout damage in your home.

If you have tile in your bathroom, kitchen, or foyer, you have probably experienced grout. Grout is the cement-like substance that glues tiles together keeping water and dirt from getting between them. For many homeowners with tiled flooring, cleaning grout is a tedious task, and no matter how often and thoroughly you clean, grout must be replaced in time.


If your grout has ripped, peeled away, cracked, or has pieces missing, you run the risk of serious water damage to your tile floor. You may also find the tiles come loose, chip, or break when grout isn’t there to keep them stable. When damaged or unstable, mold can also creep in. For minimal damage, you’ll only need to replace the grout that is broken or moldy. A total floor overhaul is only necessary if you want to change the color of the grout. Here are some steps to replacing grout.





Here are the basic materials you need to replace grout:

• A blade, such as a razor blade or X-Acto knife
• Grout
• A sponge
• A trowel
• Grout sealer


If you have a large area to replace, you may also need:

• A grout saw
• Protective ear coverings
• A brush or vacuum
• Mold cleaner

Once you’ve gathered all your materials, be sure to wear a mask and eye goggles to avoid the fumes from cleaning supplies. If you are using a grout saw to remove larger areas of grout, wear ear coverings as well.

The first step is to remove the old grout. You can either use the X-Acto knife or razor blade to scrape grout, or use the grout saw to carefully break up the lines of grout. Try to work in smaller sections to reduce the chance of injury. When you’re finished, brush away or vacuum loose grout pieces.




After this step, you may need to clean the area to get rid of excess mold (using appropriate protection). Check the tile around the affected areas for loose or broken tiles and signs of water damage. If you re-grout over a problem area without addressing the root issue, you’ll have do another repair before anticipated.

Next, mix your grout for application. The package will have instructions that you should follow carefully. If you’ve never applied grout before, mix a small amount first to get the hang of it. Grout can dry quickly, and you need to know what speed you can work at before mixing too much. Lay grout on the floor with your applicator, and be sure to fill the area generously. Scrape the top smooth, then wipe up the surrounding tiles with a towel. Repeat these steps until you’ve filled in all the places you needed to re-grout.



After the grout is cured (24 to 48 hours), you can add a grout sealer to finish the job. This acts as a protective layer to prevent breakage or mold. You may want to clean the grout with a non-bleach based cleaner before sealing it to assure it is in perfect condition before being sealed.

Avoid Future Problems

To protect your grout, a regular cleaning schedule is important. You don’t have to scrub with a toothbrush, but mopping the floor once or twice a week will be beneficial in keeping your tile clean and fresh. A bi-monthly deep clean will catch any traces of mold before it becomes an issue. Grout doesn’t need to be replaced on a schedule, but it does require consistent maintenance.
