AFM-WM® Anti Fracture Waterproofing Membrane
Peel and Stick Crack Isolation & Waterproofing Tile and Flooring Underlayments
AFM-WM is a 40 mil peel-and-stick crack isolation sheet waterproofing membrane for use beneath thin-set tile and stone applications. AFM keeps the unsightly reflective cracks (from the expansion and contraction of shrinkage cracks) from surfacing in expensive floor finishes. It is suitable as an anti fracture membrane and for waterproofing fountains, decks, kitchen floors and anywhere a waterproof or radon barrier membrane is required beneath thin-set installations.
AFM-WM not only protects your flooring investment as a crack suppression membrane, but also incorporates a 2″ overlap guide on one side of the sheet for waterproofing and as a radon barrier. The 2″ flood coated lap allows an adhesive-to-adhesive 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.
