Miracote 7505-402 1 gal MiraTop UCS Concrete Sealer Component A Dark Gray 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.
