PROTECT YOUR DECK AT MINIMAL COST
Maximize your deck’s life expectancy with SPAX® Deck Joist and Beam Tape.
A typical deck warranty will last 25 or more years—but without a protected deck substructure, splitting and rotting can occur at around 8 to 10 years, according to research by decks.com. SPAX® Deck Joist and Beam Tape optimizes the life of the deck and ensures a long-lasting, professional installation by protecting fasteners from water damage.
The flexible, waterproof tape is specially engineered with advanced synthetic adhesive to seal off fasteners, joists and beams from moisture. This high-strength, durable barrier prevents premature wood rot while allowing joists to breathe, so that your foundation lasts as long as the deck. And with a UV-resistant engineered film facer, it’s the only deck tape with UV resistance up to 10 years.
SPAX® Deck Joist and Beam Tape is part of our line of complete decking solutions, making professional, high-quality installation easy.
