At Power Pro, we’re always looking for ways to raise the bar for durability, reliability, and performance, and we’re thrilled to introduce a game-changing addition to the Power Pro® lineup: the Power Pro® Joist Tape.

Whether you're a professional contractor or a weekend DIYer, protecting your deck from the elements is essential. That’s where joist tape steps in. Power Pro Joist Tape is engineered to stop rot before it starts, delivering waterproof protection that extends the lifespan of your deck, roof beams, and other outdoor wood connections.

Joist tape is a self-adhesive, waterproof flashing tape that creates a barrier between your deck’s joists and the decking boards above. Over time, moisture can seep into the joist structure, especially around screw holes and fasteners, leading to rot, mold, and premature deterioration. Power Pro Joist Tape seals those vulnerable areas, protecting your investment and extending your deck’s life by years.

The Power Pro® Joist Tape takes that concept and elevates it with pro-grade innovation, unmatched versatility, and ultra-durable materials. It’s designed for real-world conditions and delivers real results.

Power Pro Joist Tape is made for the outdoors. Its all-weather protection means it performs in rain, heat, and cold, resisting wear from even the toughest environments. Thanks to its wet adhesion, this tape will even bond to damp surfaces, so you don’t have to stop working when the weather shifts.

Even better, this multi-material tape adheres to wood, concrete, OSB (oriented strand board), and more. It’s ideal for decking, but also versatile enough for use on other surfaces as well. Just clean and dry the surface before application (unless it’s already wet, you’re still good to go), and you’re ready to roll.

Installing Power Pro Joist Tape is a breeze. Each roll measures either 2 inches wide or 4 inches wide and 50 feet long, perfectly sized for standard 2-inch or 4-inch lumber and ledger flashing applications.

Application is simple: Cut. Peel. Stick. That’s it. No messy liners to deal with. No complicated tools required. The tape is flexible and repositionable, you have up to 15 minutes to adjust placement if needed. And its pliable nature allows it to conform to tight corners, uneven surfaces, and hard-to-reach areas with ease.

Whether you’re laying tape across dozens of joists or sealing up one repair, this tape makes the job fast, efficient, and clean.

What sets Power Pro Joist Tape apart from the rest? It’s packed with advanced features that make a real difference in both performance and durability:

• Waterproof Protection: Keeps moisture out, extending the life of your deck.

• Self-Healing: Seals around fasteners and screws to block water from seeping in.
  

• Mess-Free Application: No liner means less cleanup and more efficiency.
