About The Product

Teamac Rust Converter is a water-based chemical rust stabiliser designed to stabilise and stop the rusting process on hard-to-remove rust on metal prior to painting. Unlike mechanical rust removal that requires grinding and wire brushing, this chemical formulation converts rust into a stable black surface ready for painting, saving time and labour whilst protecting metal from further corrosion.

Developed by Teamac with over 115 years of British coating expertise, Rust Converter is the professional solution for rusted gates, railings, wrought iron, agricultural equipment, and industrial machinery where complete rust removal is impractical. The water-based formulation chemically halts the rusting process, converting iron oxide into a stable surface that primers and paints can adhere to.

When metal surfaces develop hard-to-remove rust, complete mechanical removal is time-consuming, labour-intensive, and often impractical. Teamac Rust Converter's chemical rust stabilisation eliminates grinding and wire brushing, converting rust into a stable black surface whilst stopping further corrosion. This saves time, reduces labour costs, and protects metal from ongoing deterioration.

The water-based formulation applies milky white and dries to a black stable surface, providing visual confirmation of rust conversion. The low VOC content (24 g/L) and water cleanup make it safe for occupied spaces and easy to use. Coverage of 10 m² per litre makes it cost-effective for large rusted areas.

Suitable for rusted iron, steel, wrought iron, and metal surfaces in residential, commercial, and industrial environments. Remove loose rust and flaking material with wire brush, apply Rust Converter, allow to dry, then prime with metal primers (SPO All Metals Primer, Teamac Zinc Phosphate Primer) and topcoat with metal paints (Teamac Metalcote, Teamac Industrial Coatings).

FAQ's

What is Teamac Rust Converter and when should I use it?

Teamac Rust Converter is a water-based chemical rust stabiliser that converts hard-to-remove rust into a stable black surface ready for painting. Use it when you need to stabilise rust on metal prior to painting without complete mechanical removal, saving time and labour.

How does Rust Converter work?

Rust Converter chemically converts iron oxide (rust) into a stable black surface that stops the rusting process. It penetrates rust, chemically halts corrosion, and creates a surface that primers and paints can adhere to. The visual colour change from milky white to black confirms rust conversion.

Do I need to remove all rust before applying Rust Converter?

No, you only need to remove loose rust and flaking material with a wire brush. Hard-to-remove rust can remain - Rust Converter will chemically stabilise it. This eliminates the need for complete mechanical rust removal and saves time.

Can I paint directly over Rust Converter?

No, Rust Converter is a rust stabiliser, not a primer. After rust conversion (8-24 hours depending on topcoat type), prime with metal primers (SPO All Metals Primer, Teamac Zinc Phosphate Primer) then topcoat with metal paints (Teamac Metalcote, Teamac Industrial Coatings).

How long do I need to wait before priming?

Wait minimum 8 hours before applying water-based primers or paints. Wait minimum 24 hours before applying solvent-based primers or paints. This ensures complete rust conversion and proper adhesion.

What surfaces can I use Rust Converter on?

Rust Converter is suitable for rusted iron and steel surfaces including gates, railings, wrought iron, agricultural equipment, industrial machinery, and metal structures. It is for ferrous metals only - not suitable for non-ferrous metals like aluminium, copper, or galvanised steel.

Can I use Rust Converter indoors?

Yes, Rust Converter is water-based with low VOC content (24 g/L) and safe for indoor use with good ventilation. Water cleanup eliminates solvent handling. Suitable for occupied spaces.

How much coverage can I expect from Rust Converter?

Rust Converter provides approximately 10 m² per litre at 25–30 µm DFT. A250ml tin coversnull2.5 m², and a 2.5L tin covers 25 m². Coverage may vary depending on rust severity. We recommend ordering 10–15% extra for heavy rust.

Why does Rust Converter apply milky white and dry black?

The milky white application colour provides visual confirmation of coverage. As the chemical conversion occurs, the product dries to a black stable surface. This colour change confirms rust stabilisation and makes it easy to see complete treatment.

Can I use Rust Converter on galvanised steel?

No, Rust Converter is for ferrous metals (iron and steel) only. It is not suitable for non-ferrous metals like galvanised steel, aluminium, or copper. Use appropriate primers for non-ferrous metals.

Is Rust Converter suitable for outdoor use?

Yes, Rust Converter is suitable for interior and exterior metal surfaces. After rust conversion, prime and paint to protect metal from weather. The rust stabilisation prevents further corrosion whilst primers and paints provide weather protection.

What products do I need to complete my metal protection system?

We recommend using Coo-Var Universal Degreaser for cleaning metal, Teamac Rust Converter for rust stabilisation, metal primers (SPO All Metals Primer, Teamac Zinc Phosphate Primer) for priming, metal paints (Teamac Metalcote, Teamac Industrial Coatings) for topcoating, and Application Tools. This complete system ensures maximum rust protection.
