Mapei - Ultraplan Extreme 2 Self-Leveling Weatherproof Underlayment - 50 lb

Ultraplan Extreme 2 is an advanced technology hydraulic self-leveling cementitious compound designed for the application of underlayments at an accelerated rate. It is specially formulated for leveling interior horizontal concrete surfaces in areas where environmental control systems are not operational, or in buildings that are not enclosed. Once applied, Ultraplan Extreme 2 is unaffected by exposure to intermittent rain after 6 hours, nor to freezing temperatures after 3 days of curing. Its high compressive strength is designed to allow it to be exposed to traffic as a temporary wear layer until the floor is covered with flooring. Ultraplan Extreme 2 has no restrictions on water vapor emission rates and can be installed even without testing on adequately prepared concrete supports. It is the self-leveling underlayment of choice for use under moisture control adhesive systems and epoxy vapor barrier coatings.

• Resists humidity and freeze/thaw once hardened
• Can be installed before installing HVAC systems and interior finishes
• Featuring high compressive strength, for extreme durability during construction
• Reduces substrate preparation time for floor covering application
