Protect your deck 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. Protective Joist Tape self-seals around screws and nails, blocking the primary pathway of water into lumber. When placed between treated lumber and metal, Protective Joist Tape eliminates the potential for the corrosion of the metal surface.
