Protect your deck investment from the ground up with the RW PP Deck Joist Tape, a high-performance, self-adhesive flashing tape engineered to extend the life of your deck framing. Measuring 1.89 inches wide by 50 feet long, this tape is ideal for covering the tops of joists, beams, and ledger boards—creating a durable, waterproof barrier that prevents moisture intrusion, wood rot, and corrosion.
Engineered for Long-Term Protection
Made with premium butyl adhesive, this tape forms a watertight seal around fasteners, preventing water from seeping into screw holes and wood grain.

UV-resistant top layer protects against sun damage and degradation over time.
Withstands extreme temperatures and weather conditions without cracking, peeling, or losing adhesion.
Ideal for horizontal and vertical surfaces, including joists, beams, and ledger boards.
