How it works

Not a paint. Not just waterproofing.

A multi-layer engineered membrane that protects the roof structure — not just its surface — restoring waterproofing and corrosion protection in a single system.

Each layer does a specific job — from the anti-corrosion coating that shrugs off rain and salt air, to the high-adhesive butyl that bonds into a continuous, watertight seal.

Waterproof, leak-stopping seal across the whole roof
Protects against corrosion and UV deterioration
Reflective foil layer that also helps with heat in summer
Extends the service life of the existing roof
