Universal All Surface Paint is a durable formula suitable for interior and exterior surfaces. It can be applied directly to many surfaces, including non-ferrous and galvanised metal. For optimal results on metal surfaces, we recommend priming first with Universal Special Metals Primer. If you're dealing with stain blocking, particularly nicotine and tannin bleed, use Universal Stain Block Primer before applying the paint. This advanced brush-applied paint and primer in one is designed for a variety of surfaces, making it a versatile choice for your painting needs. The paint comes in a 250ml size and is available in a Matt Black finish from Rust-Oleum.
