How to Use XFasten Joist Tape

  1. Prepare the surface. The surface should be cleaned, dust-free, and dry to promote better adhesion of the joist tape.
  2. Cut the Joist Tape. Measure the length of the joist you need to cover and cut the joist tape to the appropriate size using a utility knife or scissors. It’s typically recommended to cut the tape slightly longer than the joist to ensure full coverage.
  3. Peel off the backing. Carefully peel off the backing from the self-adhesive side of the joist tape. Take care not to touch the adhesive surface with your fingers to maintain its effectiveness.
  4. Apply the Joist Tape. It is best to maintain a construction temperature of around 20 degrees Celsius for the best result. Align the joist tape with the top surface of the joist, starting from one end. Press down firmly to ensure good adhesion as you apply the tape along the length of the joist. Smooth out the tape as you go to minimize air bubbles or wrinkles.
  5. Secure the ends. Make sure to secure the ends of the joist tape by wrapping them around the edges of the joist or by overlapping them with adjacent strips if necessary. This helps create a complete barrier.
  6. Repeat for each joist. Repeat the process for each joist, and make sure that there is proper coverage across the entire deck or flooring structure. Pay attention to any gaps or areas that may require additional attention.
  7. Inspect and trim excess. You can use a rubber roller or similar tool to eliminate air pockets and ensure strong adhesion. Inspect the installation to make sure of complete coverage and trim any excess tape using a utility knife if needed.
