Protect Your Deck from the Ground UpProtect Your Deck from the Ground Up
Introduction
When building a beautiful, durable timber deck, much of the focus goes on the boards and finish—but what about what lies beneath? At GripDeck, we know that a long-lasting deck starts below the surface. That’s why we’re excited to offer Walther Strong Deck Tape to protect your joists and substructure from moisture, decay, and premature failure.
What Makes Walther Strong Deck Tape a Game-Changer?
1. Superior Waterproofing & Longevity
- Creates a completely waterproof, air- and smoke-tight seal that protects joists from rot and weathering—oftentimes the weak link in deck longevity (Walther Strong).
- Unlike traditional wraps, this tape forms a permanent adhesive bond lasting up to 50 years, backed by a 25-year guarantee (Walther Strong).
2. Self-Seals Around Fasteners and Moisture Traps
- Special adhesive technology cures into the wood and self-seals around screws, nails, and cut ends, addressing points where moisture traditionally invades (Walther Strong).
- One installer summed it up best:“Moisture moves through wood in a lot of ways and the joist tape helps prevent that water from entering through fastener penetrations and bulk water wetting by covering the top horizontal edge. That alone is phenomenal…”
3. UV-Stable & Ultra Strong
- Made of UV-stable, non-butyl polymer acrylic—meaning it won’t degrade in sunlight and stays tough in extreme temperatures (–40 °C to +93 °C) (Walther Strong).
- The strong fiber-reinforced webbing resists tears and stays flush—boards glide smoothly over it without causing height issues (Walther Strong).
4. Environmentally Thoughtful
- Constructed from 100% recycled thermoplastics in a sustainable design that reinforces over time (Walther Strong USA).
5. Easy, Flexible Application
- Can be applied even to damp or cold timber (as long as it’s not wet or in the rain), is hand-tearable, and repositions easily during fitting (Walther Strong).
- Won’t adhere to itself on the roll—minimizing waste (Walther Strong USA).
Industry Insight: Is Joist Tape Worth It?
- Widely endorsed: Builders view joist tape as positive deck insurance—especially for treated timber subframes (lbmjournal.com).
- Evidence-backed: Trex teaches that over 90% of substructure rot begins in around 8–10 years; joist tape offers a proven defense against it (Trex Protect).
- User experiences:“…the joist tape helps prevent that water from entering through fastener penetrations…”
“It’s a great idea IMO. It’s fairly cheap insurance to help protect the most susceptible part of the deck.”
