Mainstay ML-72 is a blend of portland cement, microsilica, and other modifiers that produces a high strength, low shrinkage, and low permeability mortar used for the rehabilitation of deteriorated concrete structures such as those found in water treatment plants. Mainstay ML-72 is typically used in conjunction with an epoxy topcoat, such as Madewell 1312S White Epoxy Coating to provide the host structure with increased structural enhancement and corrosion protection.
