Behind every epoxy floor job is the work and consideration of an epoxy flooring contractor. And even beyond that high gloss sheen is a lot of prep work, some aggregate, and a hearty primer. And even beyond that, much more needs to be considered by the contractor, like the temperature of the floor, the condition of the floor, and any contaminants that are penetrating the concrete.
We recently completed the installation of an 1/16″ epoxy floor in a facility in Maryland. This floor has exposed concrete on a majority of the floor. About 1/3rd of the floor had an epoxy coating that needed removal. We used a large, planetary grinder to help abrade the concrete, and then remove the existing epoxy floor.
Once the floor was prepped, we moved in with a urethane cement primer. Urethane cement is an excellent body coat to start any floor system. In this specific facility, there wasn’t a vapor barrier beneath the concrete. This can cause major problems with only an epoxy floor. Epoxy is very susceptible to moisture transmission. The pressure between the moisture and the epoxy can cause blisters in the floor.
