What is Deck Joist Tape?
Rvhouse's deck joist tape is a water-resistant butyl adhesive used to keep moisture and water from penetrating the deck's frame. Joist tape is an affordable way to protect the deck substructure. Peel and stick flashing tape allows the wood to breathe because it is applied as a cap directly on top of joists and beams. The tape protects screw holes from moisture by acting as a barrier. Joist tape will protect the substructure from decay to guarantee foundation lasts as long as the deck does.
Rvhous's decking tape is laminated between high quality butyl adhesive and weatherproof rubber as the cover; a single sided tape especially for decking protection. Constructing anything from wood, especially outdoors, opens up a significant vulnerability. Even constructed with treated wood or built with dense wood such as ipe, a wood deck is eventually prone to mold or rot. A composite deck means the deck boards are safe from rot, but if constructed on a wood substructure, the joists and beams still need to be protected.
IMPORTANT NOTES: 1. Butyl adhesive works better on dry surfaces, wet and moisture surface will weaken the bond strength. 2. Trim off the excess rubber without butyl adhesive after installation.
