One Tape for Multiple Applications
WiseWrap Ledger Tape is designed to be a barrier against moisture that prevents wood rot and fungus, however it has many other applications as well. It can be applied to decking joists, posts, ledger boards, siding and even metal. Ledger Tape can serve as a corrosion barrier wherever the chemicals in ACQ, CA-B, or ACZA treated lumber are in direct contact with metal surfaces such as galvanized metal and aluminum.
Deckwise Ledger Tape is the perfect deck flashing to protect deck ledger boards from the accumulation of water behind the vertical wall of the structure to which it is mounted.
When this ledger tape flashing is applied over ledger boards it creates a waterproof barrier that trains water to move over the board and drip down. Wood rot is caused when moisture is allowed to seep between lumber boards and whatever it is attached to.
Degradation of in-ground decking posts is caused by fungal growth when soil comes in contact with unprotected wooden posts. This can even occur when the deck post is in a concrete base. Rot typically occurs down to six inches below grade level. WiseWrap LedgerTape acts as a barrier between the damp soil and the wooden deck post preventing wood rot. It can be used to protect all in-ground posts from mailbox posts to fencing posts.
Wood decay will also occur when deck screws or nails penetrate the deck board surface, piercing the joist sub-framing below. Deck installers can use Ledger Tape over deck joists to self-seal around nails, screws, and other fasteners to prevent the intrusion of moisture and water. Simply slit the tape into 4 inch wide strips to cover the tops of multiple deck joists. It will also assist as a noise dampening membrane between deck boards and the sub-framing.
How to Apply Ledger Tape:
Printable Application Guide
All surfaces to receive Ledger Tape must be clean, dry, and free from oil, grease and debris. Apply only when temperatures are 35°F or warmer. Use construction grade spray adhesive in cold or
difficult conditions. Attach with staples if necessary.
Ledger Board Application:
WiseWrap LedgerTape should be used along the entire length of the deck’s ledger board which is attached to the building. Determine the length of tape needed then cut off any extra. Measure 7-1/2" down the face of the ledger board and use a snap line to mark the entire length of the ledger board.
Working from the bottom up, remove paper backing and align lower edge of the tape along the snap line. Adhere to the ledger board face, over the crown pressing firmly into crease, and smooth upward flat against the wall. WiseWrap LedgerTape must extend at least 3” from the top of the ledger board up the side of the wall.
Most ledger board is 1-1/2"wide however adjustments to the lower snap line measurement should be made to accommodate variations in ledger board width.
Deck Post Application:
When protecting posts, Ledger Tape should be applied at the ground level with 2 to 3” extending above the finished grade. To determine the proper location on the post for tape placement, insert the post in the hole, mark the post indicating the grade level, and then remove the post from the hole.
To determine the proper length of tape to use, without removing the white release paper, wrap the material around the post, making sure that there is enough material for a minimum 3” overlap. Then, cut to the proper length.
Remove release paper and wrap around post while firmly pressing in place. To maximize adhesion, roll with a small hand roller. To provide additional protection against deep standing water around the post, a bead of non-silicone caulk may be applied to the top edge of the Ledger Tape.
