AFM-WM is a 40 mil peel & stick crack isolation sheet waterproofing membrane for use beneath thin-set tile and stone applications. It's suitable as an interior anti fracture membrane and for waterproofing installations. It incorporates a 2″ overlap guide on one side of the sheet for waterproofing which allows for a cohesive bond between subsequent sheets of membrane. Once the cohesive bond occurs, AFM-WM turns into a monolithic or single-ply membrane across the entire surface being waterproofed.
