Mainstay ML-72 is a blend of portland cement, microsilica, thermoplastic fiber, densifiers, admixtures, and other modifiers that produces a high strength, low shrinkage, and low permeability mortar for the rehabilitation of deteriorated concrete structures such as manholes, lift stations, wet wells, etc. Mainstay ML-72 mortar can withstand environments with a pH of 3 or higher, but is typically used in conjunction with a corrosion barrier topcoat, such as Mainstay DS-5 100% Solids Epoxy Coating. |
