Bitumen Aluminium Tape Terracotta 50 mm – permanent waterproof sealing & repair
With the terracotta bitumen aluminium tape, 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

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.
