About rust and corrosion:
Both iron and steel are prone to rust because they’re generally exposed to air and moisture. Rust forms when iron reacts with oxygen and water, it then creates a coating on the metal surface. When rust isn’t treated, the reaction (or oxidisation process) continues. This results in corrosion, which causes significant damage to metal (see HSE for more details).
A quality primer like Carboxide Metal Primer paint will provide longer term protection against rust and corrosion. Our customers say it works even when a surface has already begun to ‘ginger’ with rust.
Preparation
Surface Condition: Ensure all surfaces are free from contamination. They must be clean, dry, and free from grease.
Rust Removal: Surfaces should be free from loose rust. While this primer is effective even on metal that has begun to “ginger” with light rust, removing as much oxidation as possible before application will ensure the best long-term protection.
Substrates: Suitable for use on mild steel, carbon steel, stainless steel, cast iron, and wrought iron.
Application
Initial Mixing: Shake the can well for approximately 2–3 minutes before use. Ensure the internal agitator ball is rattling and moving freely.
Technique: Spray lightly from a distance of approximately 6–8 inches (15–20cm) from the surface.
Coating: Apply light, even coats. For heavy-duty protection or harsher environments, apply several thin coats rather than one thick layer.
Agitation: Shake the container occasionally throughout the application process to keep the pigments and zinc phosphate well-mixed.
Coating System: This primer is compatible with a wide variety of industrial and decorative topcoats, making it ideal for gates, doors, and architectural ironwork.
