where should epoxy grout be used?

Grout is a material that’s used to fill gaps between tiles and other materials in your home. It comes in different colors, and textures, and can even be used outdoors.

Grout can also be made from multiple materials, including concrete or cementitious powder. But there is one type of grout that stands out above the rest: epoxy grout.

Epoxy grout is very durable and has many advantages over traditional cement-based grouts.

Grout joints that are larger than ⅛”

Using epoxy grout for joints larger than ⅛” is a recipe for disaster. This is because the wider the joint, the more likely it is to crack.

When cracks happen in large joints (1/4″ or wider), they’re much more noticeable than they are in smaller joints and can be harder to clean out of your grout lines.

Commercial applications

For commercial applications, epoxy grout can be used to restore and protect:

  • Floors are exposed to heavy traffic, such as retail stores or restaurants.
  • Areas that need extra protection due to the number of people walking on them daily. The durability of epoxy grout makes it ideal for these situations.

Areas that get heavy traffic

Epoxy grout is a great option for areas that get heavy traffic, like kitchens. This type of grout is more resistant to wear and tear than standard grout, making it ideal for high-traffic areas such as kitchen floors.

In addition to being more resistant to abrasion, epoxy also resists stains and discoloration better than standard grout.

Epoxy also has antimicrobial properties that prevent mold from growing between tiles (and can help prevent mildew from growing on surfaces with regular use).

Epoxy’s extra durability ensures that you’ll get your money’s worth out of the floor or countertop project you’re working on—especially when compared with other types of tile.


If you’re trying to decide whether to use epoxy grout or silicone for your counters, the answer is clear: epoxy grout.

Epoxy can be applied to any countertop material and will make cleaning up spills a breeze. It’s also more durable than silicone, which means you won’t need to replace it any time soon.

Silicone is lighter weight than epoxy, which could be an issue if you have heavy objects that may shatter due to the glass being too thin in some cases (like with marble or granite).

This isn’t usually a problem when using quartzite because it’s so dense; however, if something heavy were placed on top of your quartzite countertop it could cause damage over time due to its delicate nature compared with other materials like concrete (which isn’t recommended for counters because it’s porous).

Floors, especially with tiles larger than 12”x12”

Epoxy grout is a great choice for tile floors, especially for tiles larger than 12”x12”. Epoxy grout is easy to clean and maintain, as well as more resistant to staining and mold.

It’s also more resistant to cracking and chipping than traditional tile grouts because of its strength and durability.

Showers, especially corners where water accumulation can occur

If your shower is a little on the wet side, epoxy grout can help to keep it looking dry and clean. The same is true for any place that tends to collect water or moisture. For example:

  • Bathroom walls surrounding showers and bathtubs
  • Basements near plumbing (e.g., kitchen sinks)
  • Under-cabinet space beneath kitchen counters

Areas with a lot of moisture

Epoxy grout is a good choice for bathroom floors, kitchens, and basements because it is waterproof. Epoxy grout resists mold and mildew growth, so you won’t have to worry about the appearance of your floor deteriorating over time.

Areas where mold or mildew is an issue, like basements and kitchens

An important thing to note about epoxy grout is that it’s resistant to mold and mildew. Because of this, it’s an ideal choice for areas where mold or mildew are a problem, such as basements and kitchens.

Many types of grout contain materials that can absorb moisture, making them more susceptible to damage when exposed to humidity.

Epoxy-based grouts have less absorption than other types of grout—they’re extremely durable even in damp conditions or close proximity to water sources like sinks or showers.

This makes epoxy-based products the best choice for use in wet areas like bathrooms or kitchens where there may be high levels of moisture present on a regular basis.

Outdoors, including pool decks and patios

Outdoor spaces are notoriously hard to clean, but epoxy grout is a great choice for these applications. The durable, water-resistant nature makes it ideal for pool decks and patios.

Cleaning is also easy because the grout can be swept or hosed down with little effort on the part of the homeowner.

And if you want your outdoor space to be safe from slips and falls, epoxy grout will keep it in tip-top shape by making floors non-slip without having to use anti-fatigue mats or adhesives.

Some people use epoxy grout indoors as well, but this isn’t recommended unless you’re sure that you’ll never need to clean it off—no matter how dirty things get!

Garage floors that see automotive fluids and other chemicals

Epoxy grout is the ideal flooring for garage floors that see automotive fluids and other chemicals. Because epoxy cures to form a tough, chemical-resistant surface, it can withstand extreme conditions such as moisture and mold.

Epoxy grout also resists freezing and thawing; as well as abrasion, impact, and vandalism.

Epoxy grout is the best choice in these places.

Epoxy grout is the best choice in these places. It’s durable, easy to clean, and has a variety of colors and textures. Epoxy grout is also water-resistant and resistant to mold and mildew.


Epoxy grout is a high-quality, durable material that will stand up to many kinds of abuse. It can be used in commercial applications as well as residential ones, and it works particularly well with large tiles or areas with heavy traffic.
