TIMBERTECH PRO-Tac Deck Flashing - 65' Roll - 3.25 Width

Protect your decking substructures with our heavy-duty, flexible, all-weather flashing and joist tape. This tape is designed to extend the life of your deck by forming a strong seal that prevents water penetration and protects your joist lumber from rot. To ensure proper adhesion, select a tape width that allows for overhang on each side and apply it to the top of a joist or beam with firm pressure, preferably using a hand roller. For the best results, make sure the lumber is clean and dry before applying the tape.

Our PRO-Tac tape is versatile and can be used to protect the top of joists before deck installation, as flashing for ledger board attachment to homes, or to safeguard exposed/raw end-grain. The superior sealing capability of this tape ensures that water is kept out by providing a strong seal around screws at the fastening site, without bunching, binding, or tearing during screw driving.

The tape's heavy-duty design means that its strong backing won’t easily tear, even when boards are walked on or dragged across the joist. The high-quality butyl adhesive provides an advanced, secure bond to joists that won't peel off, ensuring long-lasting protection for your deck substructures. Additionally, this tape is suitable for use in all weather conditions, rated for temperatures ranging from -70 F to 200 F degrees.

For double beams, we recommend using the 3.25” width tape to provide maximum protection. Invest in our durable and reliable flashing and joist tape to safeguard your deck substructures and prolong the life of your outdoor living space.
