ProWood 3-1/8 in. x 50 ft. Butyl Joist Tape (6-Pack)

Protect your substructure and extend the life of your deck with protective joist tape. When applied to deck joists, protective joist tape creates a waterproof membrane that prevents wood rot and decay caused by the accumulation of moisture under the deck boards. Joist tape self-seals around screws and nails, blocking water's primary pathway into the wood. When placed between treated lumber and metal, joist tape eliminates the potential for corrosion. May be used with treated, untreated, and composite wood joists. Enjoy the convenience of the 6-roll contractor pack to cover multiple projects.
