Semstone 805 is a flexible epoxy polymer coating and lining providing a chemical, water and abrasion resistant barrier for steel and concrete. This versatile coating system was developed as a self-leveling, flexible chemical resistant coating and lining and can also be used as a high build coating and lining system with the addition of a third component. Semstone 805 is a 100% solids, low odor, two-component system applied either as a neat system (unfilled), a reinforced system, an aggregate-filled system or as an aggregate filled reinforced system. A bagged Part C thixotropic agent is added for high build applications. It is most often used with reinforcing fabric (#100) over expansion joints.
