⚡ At a Glance
- • Sealing Performance: Strong self-adhesive butyl creates a watertight joint that resists moisture and prevents seepage on common substrates.
- • Best for: DIY enthusiasts and tradespeople needing fast, reliable seals in bathrooms, showers, wet rooms and outdoor repairs.
- • Not ideal for: Fine cosmetic finishing where paint adhesion over the tape is required without additional preparation.
Self-adhesive butyl tape forms immediate, flexible seals across tiles, pipe repairs and insulation boards. Available in multiple roll lengths with an 85mm width and approximately 0.80mm thickness.
Watertight sealing - thanks to self-adhesive butyl compound
Butyl composition remains tacky and malleable, forming an impermeable bond that conforms to irregular surfaces and fills small gaps. Adhesion is chemical rather than mechanical, so reliable contact to substrates creates the seal.
Creates immediate waterproof joints on tile backers, insulation boards and pipe connections. Reduces the risk of leaks without complex preparation or tools.
Flexible application across surfaces - with broad compatibility to common substrates
Adhesive chemistry is formulated to stick to a range of materials listed for wet area use, including tiles, cement backers and many insulation boards. The tape’s flexibility allows it to follow corners and curved joins.
Useful for both wall and floor repairs, and for awkward junctions where rigid solutions fail. Speeds up sealing work for both small patch jobs and larger tanking runs.
Durable outdoor performance - thanks to temperature-resistant formulation
High resistance to extreme temperatures prevents hardening or loss of adhesion when exposed to sun or cold. Lightweight, tear-resistant construction helps maintain an intact barrier under thermal stress.
Suitable for balconies, terraces and roofs as well as indoor wet areas, so long-term exposure to the elements is less likely to compromise the seal. Keeps repairs reliable through seasonal temperature swings.
