Waterproof Barrier Protection:
When this tape is applied to the top of decking joists, over ledger boards, and around support posts, it creates a waterproof seal that helps stop decay and wood rot. Rot is caused by moisture that stays in contact with treated and untreated lumber deck framing and the above decking material.
JoistTapeTM's "Super Grip" rubberized asphalt adhesive is a self-sealer around deck screws that blocks a primary pathway for water infiltration into deck joists. When it blocks this moisture and prevents wood rot, the barrier tape will maximize the life of your brand new deck or restoration.
When DeckWise® Joist TapeTM is placed between ACQ, CA-B, or ACZA treated lumber and metal surfaces, such as galvanized metal and aluminum, creating a physical barrier that prevents the corrosion of the metal surface caused by contact with the chemicals in treated lumber.
