What happens here

The presenter emphasizes the benefits of installing joist tape over the top of the deck joists. He demonstrates this by showing how water easily penetrates a screw hole in untreated wood. However, even with a screw, wood covered with joist tape shows significantly less water penetration after being soaked for 24 hours. Joist tape helps keep the joists dry, extending their lifespan and preventing rot caused by moisture seeping through fastener holes.

Goal: Protect deck joists from moisture and rot.

Tools and materials

  • Bucket — Pouring water for demonstration
  • Fastener — Demonstrating water seepage through a fastener hole
  • Joist Tape — Protecting joists from water penetration
  • Wood Pieces — Demonstrating water penetration with and without tape
  • Water — Demonstrating water penetration

edge, it has bearing. This board doesn't sit on a joist. When you step on these boards, they'll flex, fall through. Install your joist tape. Joist tape keeps your joist dry. Here's a fastener with joist tape. Here's a fastener without. After a 24-hour soak, neither fastener leaked through. If we dumped this, water soaked through the screw and penetrated about a quarter inch down. The side with the tape still that water through the screw, but got a lot less penetration. Install deck boards, account for fascia. Make two marks and chalk a line. Set your
