Waterproof Aluminum Foil Butyl Sealing Tape | Heavy-Duty Rubber Flashing Tape for Roof Leak Repair & Pipe Sealing - STK
STK's Heavy-Duty Aluminum Foil Butyl Sealing Tape is a premium, weatherproof single-sided repair tape engineered to stop water leaks permanently. It combines an extra-thick, puncture-resistant aluminum foil backing with a massive, ultra-sticky layer of pure, non-drying butyl rubber sealant compound.
Unlike cheap hardware store tapes that use low-grade asphalt that melts into a black mess during summer or cracks in winter, our pure butyl tape acts like a permanent rubber weld. It sticks instantly to almost any building surface and stays flexible forever, ensuring zero water or moisture can ever breach the seal.
