If you want to repair epoxy stone flooring, you first have to assess the degree of damage present before deciding what kind of repair method to use. You may also find it hard to find the small stones or pebbles that will be used in the construction. For minor repairs, you may not have a need for a cementitious compound. In damages that are as deep as 1/8 inch or shallower, an epoxy-based solution can save you a lot of time and effort. The epoxy bonds instantly and forms a surface that is hard and resistant to shrinkages.

Epoxy requires less finishing and is not as messy so you save a lot of time in repairing your flooring. Make sure that you clean the repair area thoroughly before doing any repair. If there are bits of flooring that need to be removed, you can use a chisel and hammer. To remove dirt thoroughly, scrub the floor with a cleanser that has neutral pH. Rinse it afterward with clean water and allow the flooring to dry.

Preparing the Repair Materials

The first thing you should do is to mix the epoxy and have the pebbles or stones at the ready. For each batch of epoxy, you are going to need a 30- to 45-minute working time. Roll 1.5 ounces of epoxy per square foot of concrete.

Mixing the Slurry

To create the slurry, prepare around 2.5 ounces of epoxy for about 1.85 pounds of small stones for every square foot of repair. Mix the epoxy and pebbles together and apply them immediately on the primer coat of epoxy you have previously laid out.

Smoothing Out the Mixture

To spread the epoxy-pebble slurry, use a trowel in smoothing it out. You can apply a trowel cleaner on your tool if you do not want the slurry mixture to stick to your trowel but this is not necessary.

Curing the Mixture

The epoxy stone flooring you have laid out will take overnight or even longer to harden completely so be sure to take drying time into your repair assessment.

Protecting Your Epoxy Stone Flooring Surface

To protect the surface of your epoxy stone flooring and to prolong its useful life, apply more epoxy as a topcoat. You can use a foam roller in applying around 1.5 ounces of epoxy to every square foot of flooring.

To keep the epoxy from having a yellowish tint over time, you can make use of a UV blocker. This is applied over the top of the epoxy. Aside from preventing the epoxy from turning yellowish, it also provides additional bonding between small stones and keeps the floor surface shiny for a longer period of time. The clear acrylic is applied by means of a common paint roller and you may use around 2.5 ounces of the material per square foot of epoxy stone flooring.

Always wear safety clothing while doing the repair. This should include work gloves, safety goggles, and a respiration mask to protect yourself against dangerous dust and flying debris.
