Because epoxy grout is so much stronger than other types of grout (particularly cement grout), you won’t even need to remove all of your old grout. You can apply new grout right over the top of the old grout.

ANSWER – It is possible to grout over existing grout if there is enough depth to do so. 1/8 inch depth may or may not be adequate depending on the type of grout used. Using an epoxy grout can be applied at a much thinner application, but you would have to apply it over all of the grout so that it matches in appearance.

Epoxy grout is a durable material that is waterproof and that resists mildew, but this durability makes it difficult to remove once it dries. The good news is that it is not impossible to remove epoxy grout from your tiles.

If you try adding new grout over your old grout, the new mixture will not properly adhere to the existing grout or tile edges, leaving your shower open to water damage.

How to remove Epoxy Grout Residue or Haze

• Make a solution consisting of 10L warm water to 100ml of Vinegar.
• Apply the solution to your tiles and scrub using a white brush pad to dislodge the epoxy residue from the tiles.
• Clean up the solution and remove the suspended resins using a heavy duty grout sponge.

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.

Whatever your motivation, it is possible to change grout color in two ways. You can either remove and replace the grout with new grout of a different color, or you can apply a colorant to your existing grout.

When applying grout colorant, you will be using either a special grout brush or a pen loaded with grout dye.

Color Your Grout to a Darker Color. As with painting a wall, darker colors generally fare better than lighter colors since they cover up stains well. For floor tile grout, one trick to minimize your cleaning efforts for years to come is to choose a grout color that resembles the soil in your area.
