Linerless Acrylic Joist Flashing Tape for Fast Application

Streamline your deck building process with GTape® Flashing Tape with No Liner (G3035BK), built on patented Nichigo G-Tape™ 3030BK technology. This innovative, heavy-duty joist and beam tape delivers the same elite waterproof protection and permanent adhesion as standard GTape, but completely eliminates the protective paper liner. By avoiding the hassle of peeling and disposing of trash, contractors save significant time and dramatically reduce jobsite waste.

Why GTape® Linerless Flashing Tape?

• Zero Jobsite Waste & Faster Install
  No paper backing means you just unroll, stick, and tear. It cuts installation time down significantly and leaves behind a clean workspace with no trash to clean up.
• Advanced Acrylic Adhesive
  Formulated with an innovative acrylic adhesive that is chemically stable and completely free of asphalt, bitumen, and butyl.
• 100% Decking Compatibility
  Due to its advanced acrylic composition, GTape is fully compatible with all PVC, composite, and pressure-treated wood decking materials, unlike traditional bitumen-based tapes that can degrade or leach over time.
• Tear-by-Hand Convenience
  Despite its industrial strength, the tape can be easily torn straight and clean by hand, eliminating the need for knives or cutting tools on the joists.
• All-Weather Performance & Flexibility
  Applies flawlessly across extreme temperatures, offering exceptional UV resistance and flexibility. It maintains a tight, permanent seal without melting or cracking.

Professional Installation Workflow

1. Preparation: Ensure the top surface of the wooden joists or framing is clean, dry, and free of heavy debris.
2. Application: Center the tape over the joist. Unroll the tape and press it firmly directly onto the flat surface. Since there is no liner, you can apply and secure it in one continuous motion.
3. Tear and Seal: Tear the tape by hand at the end of the run. Use a hand roller or firm hand pressure to eliminate air pockets and guarantee a permanent watertight bond.
4. Fastening: Drive your deck screws directly through the tape. The specialized acrylic adhesive self-seals around fasteners, keeping moisture completely out of screw holes.
