Stop leaks fast with one super-strong waterproof seal
When a roof, gutter, pipe or window starts to leak, this aluminium-backed butyl tape locks it down in seconds. The thick, ultra-sticky rubber layer moulds into cracks and uneven surfaces to form a permanent, fully waterproof bond that shrugs off rain, sun and temperature swings, indoors or out.

Why you'll love it
- Instant waterproof seal – blocks leaks on roofs, gutters, pipes, RVs and windows.
- Extreme stickiness – thick butyl rubber grips rough, wet and curved surfaces.
- Tough aluminium foil backing – resists UV, weather and ageing for lasting repairs.
- Works on almost anything – metal, glass, wood, concrete, PVC and more.
- Easy to apply – just peel, press and smooth into place, no tools needed.
