Powerlon UV Facade Sealant 290ml

Powerlon UV Façade Sealant (290 ml Cartridge)

Powerlon UV Façade Sealant is a high‑performance, UV‑resistant elastic sealant designed for sealing joints, penetrations and detailing points in open‑joint and ventilated façade systems. It provides a durable, weather‑tight bond that maintains flexibility and adhesion even under long‑term UV exposure, making it ideal for external cladding assemblies.

Powerlon UV Façade Sealant is a single‑component, moisture‑curing elastic sealant formulated specifically for façade applications where joints are partially exposed to sunlight. Its enhanced UV stability prevents cracking, chalking or premature degradation, ensuring long‑lasting performance behind open‑joint cladding systems such as fibre‑cement, HPL, aluminium and composite panels.

The sealant adheres strongly to common façade substrates including membranes, metals, timber, fibre‑cement, concrete and plastics, forming a flexible, airtight and watertight seal. Supplied in a 290ml cartridge, it is easy to apply with a standard caulking gun and cures to a tough, elastic finish suitable for both movement joints and static seals.
