Alenor Repair Patch repair patch 150x100mm
ALENOR Repair Patch is a self-adhesive patch for repairs that cannot wait: a leaking roof, a cracked gutter, a hole in sheet metal or a boat hull. It consists of reinforced aluminium foil and a thick permanent-tack butyl compound – it bonds immediately, is fully waterproof and needs no heating or drying.
The butyl layer is flexible and self-sealing: if the patch is punctured or cut, the compound flows back and closes the damage.

Frequently asked questions
Can it be applied to a wet surface?
Better not – butyl bonds best to a dry, clean surface. If it is raining, clean and dry the damaged spot before applying.
What if the damage is long?
For longer cracks and seams, use butyl tape on a roll, e.g. the BF aluminium-butyl tape.
Read more in the butyl tapes guide and see all butyl tapes.
