Pressure-sensitive tape has an aggressive “instant tack” adhesive. Works on wood, metal, fiberboard, ISO board, and concrete, as well as EPDM, TPO, PVC, and mixed elastomer roofing membranes. Seals roof joints and seams, as well as tears, punctures, leaks, and more. Plus, it features a UV-stable TPO facer that makes it ideal for flashing.
