Anti Rust Paint
(9 Products)When it comes to prolonging the life of metal surfaces, anti-rust paint is an essential line of defence. Whether you're treating gates, railings, structural steel, or machinery, applying a quality anti-rust coating helps prevent corrosion, reduces maintenance, and extends the service life of exposed metal.
At Materials Market, we stock a range of specialist anti-rust paints formulated for demanding conditions. From quick-drying topcoats to all-in-one primer and rust-inhibitor systems, our paints offer robust, long-lasting protection against oxidation - ideal for both domestic and industrial use.
What Is Anti-Rust Paint?
Anti-rust paint (also referred to as rust-inhibitive or rust-resistant paint) is a specially formulated coating designed to prevent or slow down the process of oxidation on ferrous metals, such as iron and steel.
Rust forms when metal reacts with oxygen and moisture, causing surface degradation that can compromise both the appearance and structural integrity of the material. Anti-rust paints work by forming a durable, moisture-resistant barrier that isolates the metal from environmental elements — stopping rust at the source.
Many formulations also contain active rust-inhibiting pigments such as zinc phosphate, which chemically interfere with corrosion processes. Some products can even be applied directly over lightly rusted surfaces, converting rust into a stable layer ready for finishing.
Benefits
- Corrosion Resistance: Prevents moisture, salts, and air from reaching bare metal surfaces.
- Extended Lifespan: Helps preserve the structural and aesthetic integrity of metal components.
- Cost-Efficiency: Reduces the need for frequent repainting or expensive repairs caused by rust damage.
- Versatility: Suitable for a wide range of substrates and applications, from fences to plant equipment.
- Improved Adhesion: Acts as an effective base for further topcoats, where required.
Applications
Anti-rust paint is used wherever exposed or untreated metal is vulnerable to the elements - from commercial construction to garden renovations. Common uses include:
- Steel fencing and gates
- Outdoor handrails and balustrades
- Garage doors and frames
- Farm equipment and machinery
- Marine and coastal metalwork
- Structural steel beams
- Metal guttering, downpipes and brackets
- Cast iron fixtures and fixings
Whether you're protecting new metalwork or restoring an existing structure, the right anti-rust treatment helps maintain both form and function in harsh environments.
Application Tips
To get the best out of your anti-rust paint, surface preparation and correct application are key:
- Remove loose rust, scale, and paint using a wire brush or abrasive pad.
- Degrease surfaces with an appropriate solvent if oil or contaminants are present.
- Stir paint thoroughly to ensure even distribution of rust-inhibiting agents.
- Apply in dry conditions with good ventilation. Avoid painting in damp or freezing weather.
- Use a brush, roller, or sprayer depending on the size and complexity of the surface.
Always check manufacturer guidance for surface compatibility and drying times.
Types of Anti-Rust Paint
Different projects require different types of protection. We offer a selection of anti-rust products to suit a range of needs:
Primer-Based Systems
For projects requiring maximum adhesion and a long-lasting finish, anti-rust primers are an essential first step. Our RX-90 Red Oxide Anti-Rust Primer is a fast-drying, alkyd resin-based coating designed for ferrous metals. It delivers excellent surface bonding and provides a durable base for subsequent coats.
Ideal for structural steelwork, gates, railings, and general steel fabrications exposed to the elements, this primer promotes better topcoat adhesion and helps slow down corrosion from the outset.
Multi-Purpose Coatings
When efficiency matters, a combined system offers a smart solution. ZG-90 Anti-Rust Paint acts as a primer, rust inhibitor and topcoat in one. Formulated with zinc phosphate, it can be applied directly to clean or pre-painted metal - including galvanised steel - without the need for a separate primer.
Available in a variety of colours including black, green, red, blue, white and yellow, ZG-90 is ideal for maintenance teams, quick refurbishments and touch-ups where downtime must be kept to a minimum. It offers high coverage, fast drying times, and dependable corrosion protection in a single coat.
Direct-To-Metal Corrosion Protection
For bare or damaged galvanised metal, our Zinc Rich Paints (available in silver and black) provide industrial-grade protection with minimal preparation. Made with high-purity zinc dust and epoxy ester resin, these coatings deliver excellent corrosion resistance and can be applied directly to clean steel or as a touch-up on galvanised surfaces.
They’re particularly well-suited to steel fabrications, fences, plant equipment, or any application where the goal is long-term protection in a single-stage system.
Frequently Asked Anti Rust Paint Questions
Do I Need To Use A Primer Before Applying Anti-Rust Paint?
It depends on the type of product you're using. If you're using a single-purpose topcoat, a primer like RX-90 Red Oxide is recommended to improve adhesion and long-term durability. However, all-in-one rust paints like ZG-90 include primer and inhibitor properties, allowing for direct application to prepped metal.
Is Anti-Rust Paint Suitable For Outdoor Metal?
Yes, most anti-rust paints are formulated specifically for external metalwork. They offer excellent weather resistance, UV stability, and long-lasting protection against rain, frost and airborne pollutants. They're ideal for gates, railings, outdoor furniture, steelwork, and agricultural machinery.
How Long Does Anti-Rust Paint Last?
When applied correctly, high-quality anti-rust paints can last up to 5-10 years, depending on environmental exposure and surface preparation. Regular maintenance, such as touch-ups and surface cleaning, can further extend the protective lifespan.
Can Anti-Rust Paint Be Used On Galvanised Steel?
Yes but surface preparation is key. Galvanised metal often has an oily residue or passivation layer that can prevent paint from bonding. Use a degreaser or etch primer before applying products like ZG-90, which is specially designed for direct application to galvanised and ferrous metals. It’s always good practice to follow the manufacturer's guidelines.
