Description
Walther Strong Deck Tape is a high performance, self sealing tape designed to protect timber and composite decking substructures from moisture, rot, and decay. Manufactured with a strong polymer acrylic adhesive, it provides a completely waterproof and weatherproof seal, extending the life of your deck frame and safeguarding against rot.
With a 25-year bond guarantee, Deck Tape is tested to perform with all timber treatments and across all decking types. Whether used with traditional timber or modern composite decking, it ensures the substructure stays protected from the extra moisture that can accumulate under boards, preventing premature frame degradation. Deck Tape is suitable for application after timber preservers and treatments, however the treated timber must be fully dry before application.
Deck Tape can be overlapped without affecting deck height or board stability. It’s advanced adhesive cures into the wood, and self seals around fixings (one of the primary points of moisture attack), creating a reliable airtight barrier that outperforms paint, butyl, and other tapes.
Deck Tape is manufactured using upgraded sustainable materials, including flat fibre strand laminated webbing layers made from self-reinforced thermopolymers that gradually increase in strength over time and are 100% recycled, aligning with modern sustainable building practices.
Widely trusted by installers across the UK and internationally, Walther Strong Deck Tape has become the professional standard for protecting decking subframes. With decades of field use and extensive testing, it offers unmatched durability, reliability, and performance, ensuring your deck remains safe, secure, and long lasting.
