Deck Joist Tape Description:

Deck joist tape, also known as joist barrier tape or deck flashing tape, is a specialized self-adhesive tape used in the construction of decks and outdoor structures. Its primary purpose is to protect the wooden joists from moisture, water intrusion, and other potential damages caused by the elements. The tape is typically made from a durable, weather-resistant material such as polyethylene or a rubberized asphalt compound. We are professional popular adhesive tape manufacturer, who can offer the OEM & ODM service to each customer.

The deck joist tape is applied to the top surface of the wooden joists before installing the deck boards. It acts as a moisture barrier, preventing water from seeping into the joists through the gaps between the decking boards. Moisture protection is crucial because prolonged exposure to water can lead to wood rot, decay, and structural weaknesses in the deck over time.

The tape is designed to adhere firmly to the surface of the wood, creating a tight seal that keeps moisture out. It also helps to reduce the potential for squeaky or creaky noises that may occur when the wood expands and contracts due to changes in temperature and humidity.

Using deck joist tape is especially important in areas with high humidity, frequent rainfall, or other environmental conditions that can contribute to moisture-related issues. By adding this protective layer, homeowners can prolong the life of their deck, increase its structural integrity, and reduce the need for costly repairs and maintenance in the future.

Overall, deck joist tape is a practical and effective solution to ensure the longevity and performance of outdoor decks by providing an extra layer of protection against moisture and potential damage.

Deck Joist Tape Application:

Applying deck joist tape is a relatively straightforward process, but it requires proper preparation and attention to detail to ensure its effectiveness. Here’s a step-by-step guide on how to apply deck joist tape:

Materials Needed:

  • Deck joist tape
  • Clean cloth or rag
  • Utility knife or scissors (if the tape needs to be cut to fit)


  1. Prepare the Surface:
    • Start by preparing the surface of the wooden joists. Make sure they are clean, dry, and free from any dirt, dust, or debris. Cleaning the joists thoroughly will ensure good adhesion of the tape.
  2. Inspect the Tape:
    • Before application, inspect the deck joist tape to check for any defects or damage. Ensure that the roll is not wrinkled or creased, as this could affect the seal and performance.
  3. Unroll the Tape:
    • Unroll the deck joist tape along the length of the joists, covering the areas where the decking boards will be installed. The tape should be applied to the top surface of the joists, where the deck boards will make direct contact.
  4. Cut to Size (if necessary):
    • If the tape is wider than the joists or if there are any obstructions, use a utility knife or scissors to cut the tape to the appropriate size, ensuring it covers the entire surface of each joist.
  5. Apply the Tape:
    • Carefully peel off the backing of the deck joist tape, exposing the adhesive side. Begin applying the tape at one end of the joist and firmly press it down onto the wood as you move along the length of the joist. Make sure there are no air bubbles or gaps between the tape and the wood surface.
  6. Smooth out the Tape:
    • Use a clean cloth or rag to smooth out the tape and ensure it adheres properly to the wood. This step helps to improve the tape’s bond and seal.
  7. Overlap the Tape (Optional):
    • If the rolls of tape are not wide enough to cover the entire width of the joist, you can apply additional strips of tape to overlap the edges slightly. This overlapping technique helps to create a continuous barrier against moisture.
  8. Repeat for Other Joists:
    • Continue the process of applying the deck joist tape to all the joists that will support the deck boards.
  9. Install Decking Boards:
    • Once the tape is applied to all the joists, proceed with installing the decking boards as per your standard deck construction method.

By following these steps and properly applying deck joist tape, you can ensure better protection for your deck, preventing moisture-related issues and potentially extending the life of the structure.
