how to use epoxy grout on shower walls?

Epoxy grout is a great way to update your shower. It’s durable and easy to maintain, which makes it ideal for bathrooms.

You can apply it by hand or with an epoxy grout machine in just about any color of your choice! Here’s what you need to know before you get started:

How do you apply epoxy grout to shower?

The first step is mixing epoxy grout with water. The mixture should be a consistency that can easily spread, but not so thin that it drips right off the trowel.

You’ll want to use a trowel—it’s the best tool for spreading epoxy grout evenly on your shower walls and floor.

It also makes cleanup easier because you can wipe away excess epoxy grout while it’s wet with a damp sponge or cloth before it dries completely.

Once you’ve spread the epoxy grout onto your shower surfaces, let them dry overnight before picking up any loose pieces of dried-on excess with a damp sponge or cloth (and then letting those surfaces dry again).

If there are any hard-to-reach corners or crevices in your shower walls or floor after applying epoxy grout and letting everything dry thoroughly—for example, where two tiles meet at an angle—you can use steel wool when cleaning up after application to get rid of any hardened spots here as well!

Can epoxy grout be used in shower?

Yes, epoxy grout is waterproof. Since it’s a cement-based material and will last forever, it’s an excellent choice for the shower.

It’s also easy to clean because there’s no dirt or debris that can get into the grout lines after installation. Compared to traditional grouts, which are porous and need regular maintenance like scrubbing and cleaning out mildew build-up, epoxy is much easier on your hands (and time)!

The only thing you’ll have to do is hose off with water—no elbow grease required!

If you want another reason why epoxy is better than traditional grout, think about how durable it is! It’s resistant to most chemicals such as ammonia and bleach so if there’s some liquid spillage in your bathroom then don’t worry about damaging your new epoxy job by cleaning up with these products immediately afterward; just let things dry before wiping down any residue left behind by chemicals found in everyday household cleaners/products like toilet bowl cleaner etc…

How long does epoxy grout last in a shower?

It depends on the type of epoxy grout, how much water exposure there is, and how well the grout is applied.

Epoxy grouts are more resistant to moisture than traditional cementitious grouts – some even claim to be waterproof!

However, they are not completely impervious to water. If your shower stall gets a lot of use or you have kids who like to play in their bathtub(s), then you may see signs of wear after a decade or so.

Is epoxy grout hard to install?

Epoxy grout is an easy-to-install, easy-to-clean, and easy-to-repair product that can be used in various settings.

With epoxy grout in your toolbox, you’ll save time and money on your next bathroom or kitchen remodel.

Can I put epoxy grout over old grout?

Yes! You can use epoxy grout to seal old grout and fill in any gaps. It’s also a great way to repair cracks, holes, and other damage caused by old or water-damaged grout.

However, you may want to remove loose or crumbling pieces of existing epoxy grout first before applying an additional layer over top of them.

What grout is best for showers?

Epoxy grout is a great choice for your shower walls because it’s:

  • Easy to clean. Epoxy grout is water-resistant and easy to clean, so you won’t have to worry about mildew or mold as long as you’re careful with the amount of time spent in the shower.
  • Waterproof. The use of epoxy also means your walls are waterproof—a must for any bathroom! This can be especially important if you have tile flooring (which we’ll discuss later on). If a leak occurs from above, it will not seep down into your walls; instead, the water will remain on top of them and evaporate quickly thanks to their flatness and smooth surface.
  • Expensive compared with other grouts. This might seem like an obvious downside—and yes, it does mean more money out of pocket initially—but consider that this added expense could save you money down the road by reducing maintenance costs over time because epoxy doesn’t require nearly as much work as other kinds do!

Does epoxy grout grow mold?

Epoxy grout is resistant to mold, so you don’t have to worry about it growing on your shower walls. In addition to being easy to clean and maintain, epoxy grout is also resistant to mildew and mold growth.

If a small amount of water gets into the grout lines, there’s no need for concern—the epoxy itself won’t allow it to get any more humid than drywall would.

If you notice mold growing in your bathroom, call an expert immediately.


Epoxy grout is a great product to use in your shower. It’s easy to install and has some really good benefits, like being able to be cleaned easily with soap and water.
