Protecto Wrap AFM Anti Fracture Membrane Peel and Stick Crack Isolation Flooring Underlayment 36" x 75' Roll (Model 109SPWM)

AFM Anti Fracture Membrane is made up of a tough fabric top with an aggressive rubberized adhesive that has the flexibility and strength to withstand structural movement and concrete shrinkage cracks up to 3/8" without transferring the stress load to the finished tile topping.

AFM protects your flooring investment in many ways: as an ANTI FRACTURE MEMBRANE, bridging horizontal cracks up to 3/8" in full floor thin-set applications, or as a CRACK ISOLATION MEMBRANE when an individual crack is bridged with the membrane. Meets or exceeds ANSI 118.12.
