Quick Set High-performance, quickly setting, all-purpose repair substance called MORTAR MIX. MORTAR MIX, a combination of Rapid Set hydraulic cement and high-quality aggregates, is resilient in damp situations. MORTAR MIX contains no chlorides and is non-metallic. When MORTAR MIX and water are combined, a workable, superior mortar material is created that is perfect for applications that call for quick strength growth, excellent durability, and minimal shrinking. MORTAR MIX hardens and becomes structurally sound in an hour after setting in 15 minutes.
