Hammerite \"Direct to Rust\" Metal Paint can be painted directly onto rusty surfaces and, thanks to its special 3-in-1 formula, there is no need to use a primer or undercoat...saving you precious time! It forms a superior barrier that not only seals out moisture, but also gives long-lasting protection, both inside and outside. Touch dry in an hour, Hammerite is corrosion-resistant and is suitable for use on a wide range of exterior metal including gates, railings, drainpipes, guttering and garden furniture. The paint has a subtle hammered effect with a metallic sheen, and protects up to 8 years. Two coats are required. Specification: Colour : Black Finish : Hammered Size : 250ml Coverage : 5m²/L
