Stop rot before it starts. This butyl joist tape forms a waterproof barrier over deck joists, beams, and ledger boards—blocking moisture from entering screw holes or soaking into the wood. Ideal for wet, humid, or coastal environments, it helps prevent cracking, splitting, and decay, extending the life of your deck framing by years.
Super Adhesive & Easy Install
Built with heavy-duty butyl adhesive that grips tight and stays in place. Simply peel and press—no extra tools or heating needed. It bonds quickly to wood or composite joists and conforms to uneven surfaces. No slipping, no lifting, no melting mess in hot weather.
Waterproof & UV-Resistant
Made to withstand harsh outdoor conditions, the tape resists UV rays, heavy rain, and extreme temperatures. It stays flexible and sealed through every season without cracking, oozing, or peeling.
Widely Use
Whether you're building a brand-new deck, replacing a few boards, or reinforcing an aging substructure, this 2" joist tape adapts to your project. Use it on wood or composite joists, beams, and ledger boards for long-lasting moisture protection.
