Miracote MiraTop UCS 7506-431 1 gal Bright Gray Urethane Cement Sealer Component B is a state-of-the-art, three-component, aliphatic urethane-modified cementitious concrete sealer designed for use as a topcoat over MiraTop Flooring Systems. Due to excellent UV stability and color retention it is also ideal for use as a finish coat over Miracote MPC and MiraFlex Membrane C in fountains, water features and other aquatic environments. MiraTop UCS exhibits outstanding chemical and abrasion resistance, and offers superior performance in conditions where thermal shock, high heat, wet environments and existing elevated levels of moisture vapor transmission rates may lead to failure of vapor impermeable flooring systems. MiraTop UCS is ideal for use on both new and existing concrete surfaces where restrictions on down time demand a rapid return to service upon completion of the work. MiraTop UCS is a fully reacted urethane cementitious coating technology that is non-flammable and nearly odorless during placement and cure. It complies with all Federal, State and Regional VOC requirements.
