how to mix epoxy grout?

If you’re looking to put down a new tile floor, you’ll want to find the right epoxy grout. The best grout for tile will depend on your specific project and needs, but in general, I recommend using a Type II or Type III epoxy that is designed specifically for interior use.

These types of grout are stronger and more resistant to shrinkage than other types of grout, making them ideal for use around thresholds or where movement might cause cracking between tiles

Can you mix epoxy grout by hand?

You can mix epoxy grout by hand, but it is a two-part product. This means that there is a base and mix; the base is mixed with water and the mix is added to create a strong bond between them.

In order to successfully measure out these components and make sure they are thoroughly combined, you would need something like an electric drill with a mixing attachment or something similar.

How do you mix epoxy grout for tile?

You can use a special type of grout float, called a grout hawk, to mix and apply the epoxy grout. A large surface area makes the job go faster.

You can also use a grout sponge. It will be smaller than your hawk, but still has enough surface area for fast results.

A small trowel or even spoon will work as well if you’re in a pinch!

What is the ratio for mixing grout?

Mixing epoxy grout is a two-step process. After mixing the resin and hardener together, you’ll then add your filler pigments.

The best way to mix epoxy grout is in a plastic container with a lid, like a Tupperware container or similar that can be covered between steps. Before you start mixing everything together, pre-measure all of your ingredients so they’re ready when you need them.

Mix 1 part resin with 2 parts hardener for small projects (like one gallon batches) and increase the ratio slightly for larger projects: 1 part resin to 1.5 parts hardener will work well for projects up to 5 gallons in size; for anything larger than that, use 1 part resin per gallon of water used as needed (so if you’re using 4 gallons of water as an example here), then just add enough epoxy until all the water has been absorbed into it!

This means no matter what kind of project size we’re talking about now–big or small–the same basic formula applies:

Can I add water to epoxy grout?

There are a few reasons you should not add water to epoxy grout. First, as we have mentioned before, this will result in a weak and non-adherent bond between your epoxy and the surface.

If you use too much water in your mix, it will also increase the amount of time it takes for the epoxy to cure properly.

In general, adding more than 5% of liquid by weight can reduce adhesion significantly by diluting the adhesive properties of the mixture.

Is epoxy grout difficult to use?

Epoxy grout is easy to use, so you can expect time and labor savings by using it. The main steps in the process are mixing, applying, and cleaning up after use. In general, epoxy grout requires little effort or skill on your part because it’s already mixed at the factory before being shipped off to you.

When you’re ready to apply epoxy grout into the joints of your tile, here’s what you need:

  • Gloves
  • A bucket
  • Clean water

How do you thin epoxy grout?

  • Use a paintbrush to apply the grout.
  • Use a trowel to spread the grout.
  • Use a sponge to clean the surface.
  • Use a damp cloth to clean the surface; dry with paper towels after wiping up any spills or drips that occur during application. Remember: The more you wipe off, the harder it will be for your final coat of epoxy to stick properly!

How much time do you have to work with epoxy grout?

You should use the epoxy grout within 24 hours. If you have no choice, because of weather or other factors, it’s possible to use it after 3 hours and still get good results.

The best results come from using epoxy grout within 1 hour of mixing and applying it to the surface.

If you can apply the epoxy grout within 30 minutes of mixing, then you will have even more flexibility in how long you can wait before applying it to your wall or tile surface.

If possible, mix up an extra batch just in case something happens and there is a delay in your work schedule; this way all batches are ready for application at any time during that day or week!

How do you mix 3 part epoxy grout?

To mix epoxy grout:

  • Mix equal parts of each component.
  • Stir thoroughly until no lumps remain.
  • Apply to the surface, spreading it in all directions with a trowel or similar tool. Let dry according to the manufacturer’s instructions (most commonly, 1–2 hours). Polish to create a smooth surface and then let it cure for 24 hours before handling again (many products call for 48 hours). Apply a second coat, letting it dry completely before smoothing with a fine metal trowel or steel wool pad; repeat until you’ve achieved your desired coloration and depth of finish. Finally, apply a third coat if desired; this will be much thinner than the previous coats and won’t require any polishing afterward—it should feel like wax when applied thinly enough!


Epoxy grout is a great product! It’s easy to work with, and it makes an attractive floor surface that can be used in a wide variety of places.

You should remember, however, that these are just guidelines—use your own judgment when deciding how much water or epoxy you need for your particular project.
