    ARDEX A 38™ Rapid Set Screed

    ARDEX A 38™ Rapid Set Screed is a precision-engineered, polymer-modified, cement screed that sets, hardens and dries rapidly. Use for interior or exterior applications including swimming pools and other wet areas. ARDEX A 38 can be walked on 3 hours after application and can receive tile or stone after just 4 hours, even when used as an unbonded or floating screed. After only 1 day, the compressive strength and tensile strength of ARDEX A 38 exceed those that regular cement screeds achieve after 28 days.
