MasterSeal® CR 190 (formerly Epolith-P) is a two-component self-leveling 100% solids epoxy control joint filler designed to protect joints in industrial concrete floors subjected to hard wheels and heavy loads. It provides excellent resistance to spalling, abrasion, chemical attack, and corrosion. It is also ideal for filling random cracks. MasterSeal® CR 190 is recommended for use on horizontal concrete surfaces in both interior and exterior locations.
