How to Install Epoxy Grout

Epoxy grout is the most powerful variety of grout. It is resistant to any kind of damage that a bathroom will endure; however, it is also the most difficult variety of grout to install, particularly for a beginner with no experience. Luckily, it is still possible to install your own grout in this way, provided you are armed with the right tools and knowledge. What follows should give you everything you need to know to install your own epoxy grout.

Step 1 - Preparing the Area

Installing epoxy grout in a cold room will not work very well. A warm room, and warm tiles, are much better. In order to maximize the effectiveness of your grout, you should take steps to make sure your room is as warm as possible when installing it. Allow it to heat naturally in the summer, or turn on the heat in the winter. For maximum effectiveness, the room will have to stay this way for the entire process.

Step 2 - Mixing the Grout

Your grout should come with instructions on how to mix it, which will vary between brands. Use these instructions to mix your particular type of grout properly. When you are done, your epoxy grout should be very soft and easy to spread evenly.

Step 3 - Preparing to Install

Installing the grout effectively involves working quickly and efficiently. Because of this, having your materials and tools set up and ready in advance is vital. First, get your trowel and sponge out. Dampen your sponge and make sure you have a source of water near your work area in case it dries out. Set up your tools and epoxy grout so they are within reach.

Since there are 2 steps to effective epoxy grout installation that must be done in close succession, you may want to enlist the help of a friend in advance for the next step.

Step 4 - Installing the Grout

First, use your trowel to spread the epoxy grout. Only do this over a small area. Once you have put down some grout, immediately use your damp sponge to remove the excess—or have your friend do it as you apply the next amount of grout.

No matter how fast you or your friend are with the damp sponge, the chances are good that some grout haze will be left behind on your tiles. You can use a mixture of vinegar and water to remove grout haze from your tiles. You should expect to do this multiple times, as it will rarely get all of the grout haze off on the first try.

Step 5 - Finishing Up

Repeat the process until you have installed grout onto the entire area. Once you are done, inspect your work. If you have failed to remove any epoxy grout and accidentally allowed it to dry, you can remove large chunks by soaking them with water and scraping them off, either using pieces of scrap oak or specially constructed scraping sticks. Once you have done this, use vinegar and water to remove the remainder.
