ARDEX UI 740™ FLEXBONE® Uncoupling Membrane is a high load-bearing uncoupling membrane ideal for large format tile in high traffic areas. The unique bone-shaped pattern with GripLock Technology delivers outstanding tensile bond strength. The system helps neutralize underlying substrate movement and supports and distributes heavy loads from above. Special high-performance felt helps provide vapor equalization. ARDEX UI 740 FLEXBONE can be used as a waterproof layer in bathrooms and wet areas.
