Epoxy 151 – Resin Flooring System

Epoxy 151 is a 100% solids epoxy utilizing the most cutting-edge epoxy resin technology. The resin-rich, odor-free characteristics of Epoxy 151 make for safe application and high performance in applications ranging from 8 mils WTF as a primer to ¼” in thickness with our selected graded aggregate. Deeper areas can be filled economically with heavier aggregate loading or our P-20 polymer cement product. Epoxy 151 has excellent adhesion to concrete, wood block, and most metals, and its outstanding flex allows for application in areas with mechanical or thermal shock. This self-priming resin system can generally be installed and finished with a single application in just one day.  Epoxy 151 is used for larger volume projects with standard packaging consisting of a 15 gallon kit.

Applications & Properties

Epoxy 151 has the unique property of being insensitive to moisture during installation, allowing application to proceed on new concrete that has cured for as few as seven days or in industrial plants with constant washdown procedures. Possible applications include concrete floor topping, industrial concrete repair, chemical containment liners, skid-resistant floors, expansion joint repairs, and some wood and metal applications as well.


  1. Monolithic: Epoxy 151’s elongation and bonding characteristics allow installations over non-moving cracks.
  2. Resistant to most chemical. See our chemical-resistant chart.
  3. Approved for USDA installations.
  4. Virtually odorless.


  1. Water vapor transmission upward through on-grade concrete slabs may result in loosening of epoxy bond
