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 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.

| Use Case |
Exposure to the elements outdoors can result in significant deck frame weathering. The most common area for this damage to occur is where the deck boards come in contact with the deck substructure. Protect your deck substructure with Walther Strong Deck Tape.
Deck Tape is a non-butyl tape!
Non-Butyl tapes are particularly suitable for this application as they are completely UV stable and keep their integrity for longer. This means that they have many advantages over both butyl and asphalt tapes.
In addition to this, it is stable from -40C to +93C with no cracking, peeling or strength loss.
Simply applying a strip of Deck Tape along the top of the joists as a ‘cap’ (rather than a wrap) protects the timber as it creates a strong seal from any moisture. 50mm Deck Tape works particularly well on standardised 2 inch timber as it acts as a ‘cap’ (slightly overlapping the edge of the timber) rather than a wrap. This prevents any moisture sitting on these flat surfaces and slowly rotting away the timber.
Deck Tape can be applied to joists in advance to the deck boards being fitted – It doesn’t deteriorate or affect the benefits and qualities that the tape brings to the deck.
Traditionally the coating on the metal would have slowly corroded away the metal and brought weakness in. However, by simply applying a layer of Deck Tape this prevents the breaking down of the treatments so the subframe of your deck maintains its integrity.
Generally this is a particularly weak spot for the moisture to start rotting the timber since there will not be any treatment on this part as it has been cut to size. Using one layer of Deck Tape will completely seal it off from all moisture and water-rotting or weathering.
Apply a layer of Deck Tape between the galvanised fixings and treated timber to prevent the fixing from corroding.
