Installation instructions

  • Clean the repair surface from dirt, oil etc. before the application.
  • Attach the beginning of tape close to damage area and start wrapping around (with tension).
  • Keep stretching the tape, and continue installation with 50% overlap. It will fuse to itself after overlapping.
  • Finish the wrapping over the problem area and once finished press the end firmly into place.
  • For high pressure leaks, additional wrapping may be required. Most hose repairs can be repaired with 3-5 layers in thickness, and wrapping 3 to 5 inches in each direction away from the leak point; however, additional strength can be added simply by wrapping more layers of the MF50 tape.
  • For electrical wiring, it is not necessary to stretch tightly. In fact, it will be more resilient to abrasion when it is not stretched as tightly.

Cut the tape using scissors or knife.

Maintenance and storing

It is suggested to store the MF50 tapes in dry area at room temperature away from direct exposure to light. However there is no defined storage period of MF50 tapes. According to the experience of the customers the silicone tapes would work very well even after many years of storage.
