ICO-Lastic OH is a two part,100% solids epoxy-modified urethane. With elongation of 140%, it combines the elastomeric properties of a urethane with the excellent dry and damp adhesion of an epoxy. Normally applied by roller or squeegee down to a minimum thickness of 20 mils, ICO-Lastic offers an impermeable moisture barrier against standing water. Applied by trowel in a “gun grade” version, ICO Lastic Gun Grade, it can also be used for interior expansion joints where moderate movement is expected. At minimum 60 mil thick applications, ICO-Lastic offers excellent crack bridging characteristics for inside or outside concrete structures. It will withstand light to moderate towmotor and automobile traffic.
