Mainstay® ML-72™ Sprayable Microsilica Restoration Mortar


ML-72 is a special blend of Portland cement, micro silica, thermoplastic fiber, densifiers, admixtures, and other modifiers that produces a high strength and low permeability mortar for the rehabilitation of deteriorated concrete structures. MAINSTAY ML-72 produces excellent adhesion to properly prepared new and existing concrete, brick, or steel surfaces. MAINSTAY ML-72 can withstand corrosive environments with a pH of 3 or higher, restores structural integrity, seals rough, deteriorated surfaces, and resists external hydrostatic water pressure. MAINSTAY ML-72 is suitable for permanent water immersion service.
