Protect welds and bare steel the same way hot-dip galvanising does with Chemtools GalMax 90 Cold Galvanising Paint (400g aerosol). This zinc-rich, weld-through primer contains 90% zinc in the dry film at a guaranteed 99% zinc purity, shielding clean steel by cathodic (sacrificial) reaction to deliver exceptional, long-term protection against rust and corrosion. Its zinc-loaded matt finish is ideally suited to touch-up welds, damaged structures and components, and hot-dip gal repairs. When top-coated with GalMax SG Silver, the finish becomes virtually indistinguishable from normal weathered galvanising. Trusted across marine, construction and fabrication for rust-proofing welds, bridges, cooling towers, fencing, piping, metal roofing and offshore structures.
