ARDEX B 20 is a trowel-grade, Portland cement-based, polymer modified, structural repair mortar for vertical and overhead concrete. It is used at depths ranging from 1/4 to 2 (6 mm to 5 cm) in a single lift, and can be installed in multiple lifts up to 8 (20 cm) for deeper repairs of deteriorated exterior or interior concrete. ARDEX B 20 has a corrosion inhibitor built-in to protect reinforcing steel, is easy to apply and readily bonds to concrete - virtually any vertical or overhead concrete surface that needs to be repaired.
