Transform Rust into a Paintable Surface with Professional Rust Converters
Rust converters chemically transform iron oxide into a stable compound, helping halt corrosion while preparing metal for painting. This makes them ideal for refurbishing weathered ferrous metals in industrial, commercial, or domestic settings, especially where sanding or blasting is impractical. Once the converter has cured, the surface can be finished with high-performance metal primers or a compatible topcoat. Several products also combine conversion and priming into a single step, helping reduce labour and recoat time.
These solutions are widely used on agricultural equipment, fencing, frameworks, and vehicle chassis, offering fast-drying options with solvent-free or water-based formulations. They are especially effective on irregular profiles or hard-to-reach areas where traditional preparation methods fall short. After treatment, rusted steel can be coated with various topcoats, including aluminium paint for heat resistance or additional corrosion protection in marine and industrial environments.
Rust Converter FAQs
Can rust converters be used on clean or non-ferrous metal?
No, these products require active rust (iron oxide) to work effectively. They won’t react on clean, bare steel or metals like aluminium, stainless steel, or zinc.
How should I prepare a rusted surface before applying a converter?
Remove loose rust, dirt, and debris using a wire brush or scraper. Ensure the surface is dry and free from oil or grease for proper bonding.
Do I always need to prime after using a rust converter?
Not always, some rust converters act as a primer, while others require a separate primer before painting. Check the specific product guidance before recoating.
