Frequently asked questions

View all FAQs
  • What is ACTFLEX Leak Tape used for?
    Compatibility

    Leak Tape is an aluminium-foil-faced butyl rubber tape for emergency and permanent sealing of leaks, cracks, and gaps in roofing systems, sheet joins, flashings, windows, and around penetrations. Adheres directly to metal, concrete, PVC, and masonry.

  • Where is it commonly used?
    Performance

    Roof repair (metal, sheet, tile transitions), gutter seam sealing, around skylights and roof penetrations, window flashing, and emergency leak repair on most building surfaces. Indoor and outdoor use.

  • How is it applied?
    Installation

    Peel and stick - no priming or adhesive activation required. Press firmly into place with a silicon pressure roller. The aluminium face provides heat reflection and puncture resistance; the butyl back provides permanent adhesion.

  • What length and size?
    Compatibility

    5m roll length. UV-stable, puncture-resistant, heat-reflective. Standalone repair tape - not embedded into the Forspec liquid membrane system like Meshtape or Flextape.

  • Service environment?
    Performance

    UV-stable and weather-resistant for permanent outdoor use. Butyl adhesive maintains bond strength across normal temperature cycling. Effective for both above-ground and around-penetration sealing.
