Why is it important to protect against rust?
Rust can be very damaging when it is allowed to form and left untreated for a significant period. Structures can be severely weakened and are at risk of falling down or breaking when the substrate is exposed.
Rust treatments, or rust converters, can be used to protect metal structures or substrates against rust attack. Promain are able to specify a paint, coating or treatment that will help you to eliminate rust or prevent it from forming in the first place.
Please get in touch if you want to learn what the best rust converter is to suit your needs.
Converting Rust
If you have a rusted surface that needs treating, Promain can help you to find the right solution. We offer a range of products for converting rust, including paints, primers, oils and aerosols, providing you with several different options to help you moving forward.
For surfaces that are infected by rust, you will need a product that will neutralise it or prevent it from happening again. Rust Converters work by neutralising the rust and preventing it from re-forming again.
Rust Protection
For new structures, furniture or surfaces that are un-treated, there are a range of rust protection and prevention products available to avoid rust and corrosion.
Rust Converter Paints and Primers
Within our range of Rust Converter products you will find FLAG Rust Converter, Coo-Var Rust Converter and a range of products from Owatrol and Rust-Oleum, suitable for application to rusted surfaces.
If you aren’t sure which is the best rust protector paint for you, the Promain technical department are here to guide you. By calling us today, we will be able to discuss your needs with you and point you in the direction of a product fit for the job at hand.

Rust Converters
Rust isn’t just unpleasant to look at—it can seriously weaken metal surfaces, vehicles, and structures. Left untreated, rust spreads fast and causes major surface damage, threatening structural integrity. Applying protective layers over rusted or treated metal surfaces is crucial for enhancing corrosion resistance and ensuring that subsequent treatments, such as paint, adhere properly to the metal while preventing further oxidation. At Promain, we supply a wide range of rust converters to help stabilise rusted metal surfaces, transform rust into a stable compound, and provide a long-term protective barrier against further corrosion.
Why Rust Protection Matters
When metal is left untreated, moisture, oxygen, and salt spray cause rust to eat into iron railings, vehicles, and other components. Treating rust early helps maintain the strength of steel, iron, and other ferrous metals by ensuring they are protected from further corrosion. Effective rust treatment prevents costly repairs and keeps metalwork looking clean and sound.
How Rust Converters Work
Rust converters react chemically with iron oxide (rust), turning it into a stable, non-reactive substance. Using compounds such as tannic acid or phosphoric acid, they form a protective coating that blocks moisture and oxygen. Once rust converts into a stable surface, it becomes suitable for painting or further treatment, saving you time and more effort compared to sanding all the rust away manually.
Types of Rust Converters Available
Promain offers a range of solutions to match every project:
-
Rust converter paints for a smooth, paintable surface
-
Spray-on products ideal for vertical surfaces or hard-to-reach areas
-
Primer-based converters that allow direct application onto rusty metal
-
Oil-based treatments for stabilising rust and offering long-term surface protection
Rust converters offer unique advantages compared to other treatments, such as ease of application and long-term protection.
Different products are suitable for ferrous metals, non-ferrous metals, and various environmental conditions.
Choosing the Best Rust Converter
When choosing a rust converter, consider:
-
Type of metal surface (iron, steel, copper)
-
How much existing rust is present
-
Environmental conditions (outdoor exposure, marine use)
-
Whether a primer or final finish is needed
Our technical team at Promain can guide you to the right choice based on your needs.
Rust Converter Paint Options
Our rust converters offer strong adhesion and form a protective layer over rusted areas. They are effective on both bare and painted surfaces, providing a strong protective layer. Whether you’re restoring iron railings, protecting other vehicles, or treating metal surfaces exposed to water vapour and oxygen, Promain has the right rust treatment for you.
Promain Rust Converter Products
FLAG Rust Converter - A reliable water-based product designed to neutralise existing rust on ferrous metals and create a stable surface ready for painting.
Owatrol Oil for Rusted Surfaces - This liquid treatment penetrates deeply into rusty metal surfaces, stabilising rust and forming a strong, long-lasting protective coating.
Owatrol Marine Oil - Specially developed for marine conditions, Owatrol Marine Oil protects metal structures from corrosion caused by salt spray and water vapour.
CIP Corrosive Inhibiting Primer - An excellent primer applied directly onto prepared surfaces to inhibit further corrosion and provide surface protection before painting.

Rust Converters for Cars
Car bodies are especially vulnerable to corrosion from road salt and environmental conditions. Promain's rust converters for cars treat existing rust, create a paintable surface, and protect the bare metal underneath for long term protection.
Rust Converters for Metal Structures
From iron railings to steel bridges, rust converters stabilise rusted metal surfaces quickly and efficiently. Treating metal early on protects against surface damage and maintains structural integrity, even in harsh conditions.
Applying Rust Converters Effectively
For the best results:
-
Use a wire brush to remove loose rust, dirt, and old paint
-
Apply the converter evenly using a brush or spray
-
Allow the product to cure properly at ambient temperature
-
Add a topcoat or primer if needed for further corrosion protection
Applying rust converters often does not require specialized tools, making it accessible for everyday use.
Surface preparation is key when stabilising rust and achieving a solid, protective barrier.
Can You Paint Over Rust Converter?
Yes, you can paint directly over a cured rust converter. Most Promain products are designed to leave a stable, paintable surface ideal for decorative or protective coatings.
Rust Converter vs Rust Remover
Rust converters turn iron oxide into an inert substance, while rust removers strip all the rust away completely. Both types of treatments vary depending on the extent of corrosion and the desired finish.
Common Mistakes When Using Rust Converters
Avoid:
-
Skipping surface cleaning
-
Applying too thick a coat
-
Painting before the surface has fully cured
Good application practices mean better, longer-lasting surface protection.
How Long Does a Rust Converter Last?
Rust converters offer protection for three to five years or more with proper maintenance. Factors such as environmental conditions and surface preparation influence longevity.
Best Practices for Rust Treatment Maintenance
Regularly check for any surface damage or worn spots. Touch up these areas with rust converters or rust inhibitors to ensure ongoing protection.
Top Tips for Rust Protection
-
Always clean and prepare the surface properly
-
Choose the right product based on metal type and exposure
-
Apply treatments at the correct ambient temperature
Taking care at the beginning saves time and avoids more effort later.
