5m Aluminium Waterproof Tape

5M Heavy-Duty Aluminium Foil Waterproof Butyl Tape (High-Temperature Rubber Sealant Flashband Tape for Roof Leaks, Pipe Cracks, Gutter Repair, RVs & Boat Marine Sealing)

Stop water leaks and seal cracks instantly with this 5M Heavy-Duty Aluminium Waterproof Butyl Tape. Formulated with a thick, self-adhesive butyl rubber layer bonded to a reflective grid-embossed aluminium foil backing, this industrial-grade sealing tape forms a permanent, airtight, and watertight barrier over damaged surfaces—curing cracks across metal roofing, PVC plumbing, gutters, and water tanks without requiring torches or messy liquid sealants.

Key Features

1. Instant Permanent Water Barrier: High-viscosity butyl rubber penetrates deep into surface pores and hairline cracks, creating an impenetrable waterproof seal against active moisture, rain, and water pressure.
2. Sun-Reflective & Weatherproof: Heavy-duty aluminium foil surface blocks ultraviolet rays, deflects solar heat, and withstands harsh weather conditions without drying out, peeling, or cracking.
3. Extreme Temperature Tolerance: Maintains strong elasticity and holding power across a wide temperature spectrum, resisting softening during intense midday roof heat and brittleness in cold environments.
4. Puncture & Scratch Resistant: Reinforced diamond/square embossed foil mesh resists mechanical abrasion, surface friction, punctures, and aging from outdoor exposure.
5. Broad Surface Compatibility: Adheres aggressively to virtually all common building materials, including galvanized steel sheets, concrete, PVC pipes, glass, wood, fiberglass, tile, and asphalt roofing.
6. Hassle-Free Peel-and-Stick Setup: Simply cut to length with household shears, peel the non-stick protective backing film, and press firmly over the target crack for a clean, permanent repair.
