or 4 interest-free payments with
Aluminium-faced butyl tape for metal roofs, gutters and flashings. Sticks straight away, sits in full sun, seals from minus 25°C to plus 121°C.
ACTFLEX FLASH FOIL is a self-adhesive butyl tape with a reinforced aluminium face for sealing exposed joints and leaks. The butyl grabs metal, concrete, fibre cement, plasterboard and plastics on contact. The foil face is puncture proof and stays put under UV, dust and heat.
What it's for
- Metal roof joints, overlaps and ridge caps
- Leaks in corrugated and sheet metal roofs, gutter repairs
- Roof penetrations: vents, skylights, chimneys and ducts
Why waterproofers buy it
- Sticks on pressure rolling, no cure period. Rain on it straight away
- UV resistant, suits permanently exposed work
- Conforms to corrugated and curved profiles
- 10 year Forspec product warranty
Specs
Reinforced aluminium foil face, self-adhesive butyl. Lap 50 mm minimum.
Not for
Damp, dusty or oily surfaces, bridging unsupported gaps, movement joints, or use as an area waterproofing membrane.
Reinforced aluminium foil facing, puncture-proof and weather resistant
UV resistant, so it suits permanently exposed applications
Immediate permanent tack to metal, concrete, fibre cement board, plasterboard and plastics

Technical overview
Key applications
- Roofing and flashing - sealing metal roof joints, overlaps and ridge caps
- Waterproofing around roof penetrations - vents, skylights, chimneys and HVAC ducts
- Temporary and permanent repair of leaks in corrugated and sheet metal roofs
- Gutter repairs and joint sealing
- Cladding and wall systems - joint sealing between fibre cement board, plasterboard and concrete walls
- Sealing facade panels and junctions in exposed conditions
- Windows, doors and facade detailing - air and water sealing around frames and door gaps
- Transition sealing between dissimilar materials - metal to concrete, metal to glass, cement to steel
- Vehicle and portable structures - RV roofs, caravans, trailers and mobile structures
- Patching cracks in cementitious boards and waterproofing concrete expansion joints
Surface suitability
- Metal (clean, dry, with loose fasteners, swarf and debris removed)
- Concrete (clean, dry, sound and smooth across the full bearing width; primed where porous, dusty or friable)
- Fibre cement board (fixed per the manufacturer instructions and the applicable Australian Standard; primed where porous, dusty or friable)
- Plasterboard (fixed per the manufacturer instructions and the applicable Australian Standard; primed where porous, dusty or friable)
- Glass (clean, dry and free of all bond-inhibiting contaminants)
- Plastics (clean, dry and free of all bond-inhibiting contaminants)
Not a waterproofing membrane. ACTFLEX FLASH FOIL is a flashing and sealing tape, not an area waterproofing system, and it is not a substitute for correctly designed flashing, capping and drainage detailing. Do not install over damp, frosted, dusty, oily or contaminated substrates - the butyl will not develop permanent tack. Do not stretch the tape during installation, as an installed tape under tension will pull back off the junction. Do not install below 5C without pre-warming the tape and substrate and confirming adhesion on a trial area. Porous, dusty and friable substrates must be primed before the tape is applied. Do not bridge a gap with unsupported tape - the tape must bear on sound substrate on both sides of the joint. Not a movement joint product: designed movement joints require the specified joint sealant or joint tape. Roller pressure is mandatory, as an unrolled tape is not a sealed tape. Confirm compatibility with a FORSPEC technical representative before use over bituminous products or unverified coatings.

Frequently asked questions
-
What is ACTFLEX Leak Tape used for?
CompatibilityLeak 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?
PerformanceRoof 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?
InstallationPeel 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?
Compatibility5m 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?
PerformanceUV-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.
