This self-adhesive waterproof sealing tape is made with high quality SBS polymer modified rubber asphalt paired with a white fluorocarbon film surface, with a temperature resistance range of -4°F (-20°C) to 158°F (70°C). The fluorocarbon layer provides up to 20 years of anti-aging performance, offering strong durability, tear resistance and temperature stability through strong F-C bonds, preventing cold cracking and heat melting, while reflecting UV rays to lower surface temperatures. It also delivers reliable corrosion resistance, flame retardancy and puncture resistance. Its dual-layer design includes a PVDF moisture barrier and a bitumen layer that penetrates substrates to create a fully sealed, watertight bond that self-heals minor damage, with elasticity to accommodate thermal expansion and contraction of surfaces. Ideal for use on roofs, driveways, wood, gutters, metal surfaces, concrete, basements, pools, pipes, chimneys and more, it also serves as a root barrier for DIY plant projects like flower boxes and green roofs. Installation is straightforward: clean and dry the target surface, peel off the backing and press firmly, and it can be cut to custom sizes with a sharp knife or scissors.
