Cement: This system was the only system available for years and is used both in thin and thick projects. Normal wear can be expected to affect the aggregate more than the cement.
Epoxy: This system has superior adhesion qualities and color range not available with cements. With its high abrasive resistance, resists wear and also decreases the wear of the aggregate yielding somewhat better durability. Both systems can be expected to last the life of the building, even with heavy use.
