With the Rust-oleum Hard Hat 2182 anti-rust primer, you reliably protect new, bare, or slightly rusted steel and iron against corrosion. Active rust-inhibiting pigments penetrate deep into the surface, stopping rust formation beneath your topcoat. Thanks to its fast-drying formula, the coat is touch-dry in just 15 minutes and ready to handle after 30 minutes. You can recoat within 1 hour or after 48 hours. The smooth, matt grey finish provides optimal adhesion and creates the ideal base coat under light-coloured topcoats for maintenance work on railings, steel structures, or machinery. This convenient 500ML spray can easily covers a surface area of up to 2.5 m².
