Like any other adhesives, ensuring proper installation is highly essential.  Here are some tips to help you with the installation process:

  • Make sure that the surface is clean, dry, and dust-free. Thoroughly dust the area, clean it with an alcohol solution (if applicable) and let it completely dry before applying the tape.
  • Peel the tape from the roll. The tape itself is easy to tear so you shouldn’t have any problem. An important note to make, though: make sure to not touch the adhesive side too much as oils from your hands or any other foreign materials can contaminate the adhesive and lessen its bonding strength.
  • Conform the tape to the surface you are applying it to.  This eliminates any gaps that may exist between the tape and the surface. The tape is conformable so make sure that you mold and press it against the surface’s bumps, curves, and empty areas, covering every possible area.
  • Apply multiple layers of the tape to make the the patch thicker. This set-up would significantly increase the strength, stability, and air and watertight properties of the application. Eliminate any air bubbles which may exist by applying pressure on the area of application.
  • You can trim any adhesive that oozes out using a plastic knife or any plastic card.
  • Wet your fingers with soapy water (just normal 50-50 mix of water and soap), and rub it on the tape’s surface. This will smoothen the butyl rubber, reduce any bumps or lumps, and give your installation a smooth and professional look!
  • Allow the tape to cure, dry, and acclimatize overnight before exposing the surface to any harsh conditions. If this isn’t possible, then letting the tape set for at least 3-4 hours would be sufficient.
