can epoxy grout be used on marble?

Marble is a beautiful stone and it’s not surprising that people have been asking about epoxy grout for marble. You may be wondering if epoxy can be used on your marble.

Or maybe you’re wondering if there’s any advantage to using epoxy over regular grout or other products that claim to work with marble. If so, let me help answer these questions!

What kind of grout do you use on marble?

Marble is a porous stone, which means it can absorb water. If you’re using a traditional concrete-based grout that’s made with silica sand and cement, the absorption could cause staining and discoloration on your marble surface.

Epoxy grout is stain resistant and is naturally waterproofed so it won’t seep into the pores of your stone—which means less fading or discoloration over time.

Can you use epoxy grout on natural stone?

Epoxy grout is a good choice for marble, granite, and limestone. But it’s not recommended for travertine.

Travertine is a natural stone that’s formed from deposits of limestone on the floors of hot springs and at the bottom of rivers.

It has a high porosity and can absorb water easily; epoxy grout might cause it to crack or chip away if it gets too wet (see below).

Do you need special grout for marble tiles?

You’ll want to use epoxy grout if you have marble tiles. Epoxy grout is stronger, more durable, and better for sealing than standard types of grout. It is also more expensive, so it may not be necessary for all situations.

Does marble absorb grout?

Grout is porous, so it will absorb some of the water in your environment. However, marble is not porous and does not absorb grout.

In fact, all of these materials (marble, granite, travertine, and limestone) have a very low absorption rate for liquids such as grout; sandstone has an even lower rate.

When should I use epoxy grout?

Epoxy grout is a great option for marble. It’s more durable than ceramic or porcelain tile and can be used for both indoor and outdoor projects, as well as flooring and walls.

Epoxy grout is also very easy to clean, making it ideal for high-traffic areas such as bathrooms.

How do you grout marble?

Once the marble is prepped, you’re ready to grout it. The first step is always to apply the grout. For this project, we used Epoxy Grout by Fusion Products because it’s easy to use and doesn’t require any special tools or equipment (though there are some optional extras that make life a little easier).

The best way to get an even coat of epoxy on your marble tiles is with a grout float—a long plastic tool with a sponge-like head at one end and an angled handle at the other end.

You can find these in hardware stores or online for about $5-$10 each; just be sure not to use one made from metal!

Once you’ve spread out an even layer of epoxy over all your tiles, simply let it sit for about 5 minutes before wiping off excess material with a damp sponge.

If there’s still too much material stuck on each tile after 5 minutes have passed (and/or if you just want them looking extra clean), give them another quick run through with an old toothbrush dipped in water until everything looks good as new again!

Does epoxy grout turn yellow?

One of the main reasons epoxy grout is more expensive than standard grout is because it’s far more durable, stain-resistant, and water resistant.

If you want an easy-to-clean and maintain floor that will last for a long time, epoxy is the way to go.

When it comes to cleaning your floors, most people just use warm soapy water with a mop or broom. But if your home has been flooded with water from burst pipes or heavy rainstorms, then you may want to consider using bleach instead of soap when cleaning up after flooding issues occur—and this can also help prevent mold growth in your home as well.

Is epoxy grout worth the extra money?

In a nutshell, yes. Epoxy is more expensive than other types of grout but it offers several benefits that can make a big difference in your project.

Why is it more expensive? Because epoxy requires special equipment to install and cure properly, as well as a special adhesive for the joints between tiles.

The cost of this equipment and materials adds up quickly so overall you’ll pay more for your job than if you were using regular tile grout or mortar. But don’t worry—there are still plenty of reasons why you might want to invest in epoxy!


If you’re looking for durable, easy-to-clean grout that will last for years and won’t turn yellow, then epoxy might be right for you.

On the other hand, if cost is an issue and marble is not in your budget (or if it’s just too beautiful to cover up), then there are many other options available.

Really though, I think it depends on how much time and money you want to spend on maintaining your flooring!
