Cement-based grout, no matter how well it is sealed, can begin to fall apart over time because it is porous and easily absorbs liquids and other contaminants that can degrade its integrity. Unsealed cement-based grout won't last long at all and should be sealed immediately.

You Can Regrout to Change the Color of Your Grout
Epoxy grout is superior compared to its cement-based counterparts and can last longer. Some epoxy grout doesn't even require sealing, but it can still begin to have issues over time. Some people would just like to change the color of their grout.

Cracks, staining, and mold are some of the other reasons why you may need to regrout your tile surfaces. Wear and tear from age, crumbling, and discoloration are also signs the grout needs to be repaired.

Can You Regrout Over Existing Grout?

Replacing grout completely is always an option, but that can be more costly and not always necessary. In some cases, you might be able to regrout over your existing grout. Doing it yourself might even be an option if you have some basic home repair skills.

The big advantage of regrouting over old grout is that it can save you a great deal of time and money. You'll do far less work when you apply new grout over old grout and you will use less grout.

Cracked, Stained or Moldy Grout Are Top Reasons for Replacing Grout
When selecting the grout you want to use, epoxy grout is a good choice. You don't have to remove all of your old grout to apply the new grout. The new grout can be applied right over the top of the existing grout.

You will need a grout removal tool, which is a small tool with a sharp blade capable of chipping away the grout. To remove the top layer of grout, simply chip out the old grout to a depth of at least 2mm (about the thickness of two dimes together).

Remove About Half the Thickness of the Grout
Work slowly and in small sections as you remove the top layer of old grout. Precision isn't necessary as long as you remove at least the minimum depth. The more even it is, of course, the easier it will be to evenly apply new grout.

When the old grout has been removed, use a handheld vacuum or a brush to make sure there aren't any remnants of grout dust. You want the area clean before you apply new grout.

Now you're ready to apply new grout to fill in the space you cleared out. Use a grout float to apply the new grout the same way you would if you were grouting a new project.

Press the float onto the tiles at a 45-degree angle and spread the grout evenly until the grout lines are filled completely.

Wipe away the excess grout using a wet sponge and then let the new grout cure before applying a high-quality sealant if required.
