Key benefits Protects wooden decks from water and corrosion and helps extend lifespan by providing a durable moisture barrier on deck components such as rim joists and related structures. Strong and flexible butyl adhesive ensures a secure, long lasting bond to wood and other surfaces, reducing the risk of edge lifting and gaps. Weather resistant and suitable for a wide temperature range (20F to 176F), performing in most weather conditions and maintaining adhesion through freezing and heat. Easy to install with minimal steps: clean and dry the surface, cut the tape to the needed length, then apply to the wood deck. Compatible for wood decks and other structures. Can be cut to fit rim joists and related flashing areas. Material and performance Butyl tape with waterproof and corrosion resistant properties designed to form a reliable flashing layer on deck components. Delivers consistent performance across seasons and weather patterns, helping reduce moisture intrusion around deck rims and joists. How to use Prepare the surface by cleaning and drying the area to be treated. Cut the rim joist tape to the required length for your project. Apply the tape to the wood deck, pressing firmly to ensure a strong seal. Use scenarios deck installation: Apply to the rim joist area during construction to create a durable moisture seal before decking is laid. Retrofit on existing decks: Seal exposed rim joists and gaps to prevent water intrusion and prolong deck life. Outdoor structures: Use on stairs, porches, or related flashing applications where moisture protection and long term adhesion are needed.
