Joist Barrier--After cutting your tape to the proper length for your joist, apply tape centered over the joist and wrap around the edges. Press firmly and for additional adhesion roll with a hand roller.

Protecting your posts for your new deck--DeckWise Joist Tape should be applied at the ground level with 2-3 inches extending above the ground. Place your post in the hole and make a mark at ground level. To determine the lengths of tape you will need, without removing the white backing, wrap the tape around your post making sure to leave a 1" overlap. Cut your tape to the correct length. Remove the backing as your wrapping it around your post, press firmly in place as your go. Once done, go over the tape with a small hand roller. For additional added protection, you can caulk the top edge of the joist barrier tape.

Corrosion Blocker--if you apply DeckWise® Joist Tape™ between ACQ, CA-B or ACZA treated lumber and metal surfaces (such as aluminum or galvanized metal), it creates a barrier that will prevent corrosion of the metal surface by preventing contact with the chemicals in the treated lumber.
