This Metal Oxide Primer is a professional-grade, long-oil polyurethane coating enriched with anti-corrosive metal oxide pigments. Designed to penetrate and seal bare steel, aluminium, cast iron, and hardwood timber, it forms a durable barrier against rust, corrosion, and surface degradation.
Its semi-shine finish maximises adhesion for subsequent solvent-based enamels, machinery paints, and polyurethane topcoats, making it ideal for industrial fabricators, skip builders, maintenance workshops, and DIY restoration projects.
The primer’s high-solids formulation delivers excellent flow, self-leveling properties, and a slightly flexible finish to accommodate metal expansion, reducing the risk of cracking or flaking. It can be applied by brush, roller, or spray (HVLP or airless), and may be thinned up to 15% with white spirit for spray applications only. Once cured, it sands easily to produce a super-smooth base for topcoats.
Manufactured under ISO 9001 quality standards in the UK, Metal Oxide Primer is available in Grey and Red oxide primer colours, supplied in 5 L, 10 L, and 20 L tins to suit small repairs or large-scale industrial projects. This versatile primer provides long-lasting corrosion resistance while preparing substrates for a flawless finish with a wide range of compatible coatings.
