Ardex FlexBone Floating Uncoupling Mat 215 SF Ardex's new revolutionary, loose-laid floating system provides 100% uncoupling, movement protection. The membrane's separation from the underlying substrate results in significant time and cost savings through minimal required substrate preparation. This is the only unbonded tile underlayment available that does not require you to install using a thinset mortar or adhesive. Instead the Ardex 720 Flexbone is laid over the substrate, or floor covering, then prepped for tile installation with the tile approved thinset mortar over the Flexbone underlayment. This in turn allows you to save 50% of your tile thinset mortar costs! The Ardex 720 Flexbone has a unique bone-shaped pattern with GripLock Technology for the highest level of mortar-to-membrane bond strength. The tile underlayment is constructed of a highly durable, flexible plastic and laminated, topside glass fiber mesh that contains self-sticking overlaps for easy seam connection. Substrates provide a variety of challenges for the tile and stone installations. Wooden and concrete subfloors go through various cycles of expansion, contraction and deflection during the life of a floor covering due to changes in weather, moisture conditions and inherent subfloor properties.
