The grey twin to the clear version, for repairs where blending with a Colorbond roof matters more than an invisible patch. Sprays on, seals the crack and stays flexible where a tube sealant would sit stiff.
It reaches into laps and corners a caulking gun can't nozzle into, dries to a firm but flexible waterproof finish, and takes paint once cured if you want to match it closer to the roof colour. Good on gutters, roofs, flashings and ductwork.
For small holes and hairline cracks this is a fast fix. Bigger damage still needs a proper repair.
Full specs are in the tabs below.
