ARMOFLOOR MB4 is a high-build, two-component elastomeric polyurethane membrane formulated for demanding waterproofing applications. Upon curing, it creates an impermeable, highly elastic layer with outstanding crack-bridging ability, abrasion resistance, and chemical durability. Designed for integrated systems in car park deck coatings and multi-story parking waterproofing, ARMOFLOOR MB4 offers superior flexibility to accommodate structural movement. Its fast-drying, chemically cured composition resists detergents, oils, grease, and cleaning materials, while delivering excellent wear resistance and long-term weatherability in heavy-duty environments.
