Hammerite Direct to Rust Smooth Metal Paint is specially formulated to perform as primer, undercoat and topcoat in one. The solvent-based formula is easy to apply and gives a very durable finish once fully dry. On previously painted metal in sound condition, 1 coat should be sufficient. On bare/rusty metal 2 coats are required. Ensure that all edges and corners are adequately covered. Do not over-apply as sagging will occur. Available in a set range of colours and sprays.
