Bitumen Aluminium Tape 50 mm – permanent waterproof sealing & repair
With the bitumen aluminium tape in aluminium colour, you can quickly and reliably seal joints, transitions and damaged areas outdoors. Whether for roofs, gutters, sheet metal, steel structures or glass roofs/greenhouses: the tape is self-adhesive, offers strong adhesion and is ideal as a sealing and repair tape.
Why choose this aluminium tape?
- Waterproof sealing – perfect for joints, cracks and connections
- Self-adhesive – quick application without special tools
- Strong adhesion thanks to elastomer bitumen coating on an aluminium/PE composite
- UV and weather resistant thanks to the aluminium surface
- Tested for water impermeability according to DIN EN 1928
Typical applications
- Sealing joints and cracks in gutters, sheet metal and roof coverings
- Permanently waterproof sealing of glass roofs & greenhouses
- Eaves and valley flashing, sheet metal overlaps & steel structures
- Sealing corrugated fibre cement roof panels
- Timber frame construction: transitions between wall and floor slab in the plinth area, sill/basement or floor slab
- Waterproof sealing under window sills
- Sealing wood fibre under-roof boards and wall boards in house construction
- Sealing precast concrete retaining walls in landscaping
- Waterproof bonding and sealing of roof windows, chimneys & pipe penetrations
- Roof and wall connections
Application – how to achieve a proper seal
- Prepare the substrate: dry, clean, free from dust and grease, abrasion-resistant and load-bearing.
- Porous/monolithic substrates such as stone, rough concrete or plaster: use Universal Primer.
- On old timber boarding, roof tiles and old bitumen waterproofing, use our Bitumen Primer V.
- Ensure a minimum temperature of 10 °C for the tape and substrate.
- To improve adhesive strength, warm the substrate and tape to 20 °C.
- Positioning: align the tape and remove the release film.
- Apply & press down: press firmly, avoid cavities and air bubbles, ideally using a pressure roller.
- Note: Each roll of tape includes application instructions.
Important: The product is not compatible with silicone and must not come into contact with silicone-containing substrates.
