VersaFlex VF 30 is a low viscosity, high solids epoxy developed as a penetrating concrete primer for polyurea applications. VF 30 penetrates and strengthens the surface of the concrete, reduces pin-hole formations and provides a chemically reactive surface to accept VersaFlex polyurea systems. Adhesion is increased with the use of VF 30 by up to three times that of unprimed concrete.
