How Do You Use Joist Tape

At the edges of the joist, cut slits at the corners, and wrap the flashing tape downward over the board. Securely fold the tape over the sides and end of the joist. Continue this process and apply tape to any surface that can hold water: all joists, rim joists, beams, and ledger boards.

Is Joist Tape Needed?

Joist Tape: Why It’s Essential & When to Use It In order to protect your deck’s substructure from weathering and moisture, protective tape for your joists is a must.

Can I overlap joist tape?

JoistTape™ must overlap any previous tape on adjoining joist runs and/or any ledger board side edges must have an overlap. Slightly stretch the JoistTape™ to avoid wrinkles and press the self- adhesive side down as you move along the length.
