Grey Primer is a fast-drying, anti-corrosive undercoat formulated to protect ferrous metalwork and provide excellent adhesion for subsequent topcoats. Its neutral grey shade offers superior opacity and coverage, helping to hide surface variations and deliver a smooth, even base for finishing systems on site or in the workshop. Key Features & Benefits Anti-Corrosive Protection: Helps inhibit rust formation on prepared steel and iron. High Adhesion: Improves key for a wide range of finishing coats. Fast Drying: Short recoat times support efficient workflows. High Opacity Grey: Levels well to create a consistent base that hides colour and patchiness. Interior & Exterior: Suitable for fabrication and maintenance work. Product & Technical Details Type: Anti-corrosive metal primer (grey) Substrates: Ferrous metals (steel/iron) correctly prepared Colour/Finish: Grey primer (matt/eggshell) Overcoat With: Compatible alkyd, acrylic or polyurethane topcoats (check compatibility) Environment: Interior & exterior Typical Uses: Gates, railings, structural steel, brackets, machinery guards, general metalwork Suitable Applications Priming new or prepared steel prior to decorative or protective coatings Maintenance of railings, gates, fences and fabricated components Touch-up of cut edges, drilled holes and repair areas Instructions for Use Prepare surface: remove rust, mill scale and loose coatings to a sound substrate; abrade, degrease and dry. Stir thoroughly. Apply thin, even coats by brush, roller or suitable spray. Allow to dry fully between coats; follow recommended recoat windows and film build. Test topcoat compatibility on a small area before full application. Limitations & Precautions Not for direct use on non-ferrous metals without suitable priming. Apply in dry, well-ventilated conditions above 5 °C; avoid high humidity. Observe product safety guidance; keep away from ignition sources where applicable. Grey Primer provides a reliable, high-coverage base that improves adhesion and extends coating life on ferrous metalwork—ideal for both fabrication and ongoing maintenance.
