OR E41 is a two-component, water-based epoxy primer that can also serve as a standalone coating. Water-based chemistry means low odor and easy cleanup with warm, soapy water while wet (mechanical removal once cured).
Use it to prime concrete floors and masonry ahead of polyurea or urethane topcoats, or as an economical protective coating in its own right. Available in matte black, red, green, brown, and light and dark gray.
Theoretical coverage is approximately 500 sq ft per gallon at 3 mils; actual coverage depends on surface porosity and texture.
