The Hammerite Metal Paint Hammered Black is specially formulated to perform as primer, undercoat and topcoat in one. A durable, corrosion resistant decorative coating for ferrous and non-ferrous metals, certain plastics and wood. It can be applied directly onto rusty metal thanks to a formula that has been developed to be a primer, undercoat and topcoat in one. It gives a hammered effect finish which is smooth to touch and sheds water well whilst forming a barrier that not only seals out moisture but gives long lasting protection, both inside and out. Easy to use, apply it on ferrous and non-ferrous metals. Comes in hammered black in a 250 ml and 2.5 L tins. This range is designed to protect metalwork from humidity, rain and rust.
