Epoxy floor coating

Epoxy is a resin system, and Sherwin-Williams places it in the group called resinous flooring. It says epoxy became the most successful resin in flooring in the mid-twentieth century because of its durability and strong adhesion.

Resinous products come in three basic types, by thickness: coatings of 4 to 30 mils, slurries of 30 to 250 mils, and mortars of 125 to 250 mils or more. A coating is the thinnest and often has no fillers.

The coating is only as good as the slab under it. The surface must be clean, sound and profiled through concrete grinding, and the slab must be dry. Slab moisture pushes coatings off, so ask how it will be tested and whether a moisture barrier is needed.

Compared with polished concrete, epoxy gives you color, pattern and a sealed top layer, but Sherwin-Williams notes epoxy resins are typically very hard and can scratch fairly easily. Choose by use: forklifts, chemicals, looks and budget.
