Planiseal Max is a two-coat, high-solids, polymer-based, moisture-control membrane and textured primer for self-leveling underlayments. Planiseal Max protects flooring installations against subfloor moisture and pH in concrete slabs with moisture vapor emission rates (MVERs) up to 25 lbs. (11.3 kg) per ASTM F1869, relative humidity (RH) up to 100% per ASTM F2170 and alkalinity protection up to pH of 14. Planiseal Max eliminates the need for a secondary primer for self-leveling applications.
