MORIENT MORTAR™ Premium Self-Leveling is a versatile, quick-setting, and high-flow high-belite calcium sulfoaluminate cement-based self-leveling underlayment that easily levels floors prior to the installation of ceramic tile, natural stone tile, resilient flooring, carpet, wood, and other floor coverings. This high-strength, easy-to-handle underlayment is dimensionally stable and non-shrinking, which effectively eliminates installation problems such as bond failure, crumbling, and staining of resilient flooring caused by the free moisture commonly found in traditional, Portland cement-based underlayments.
