Why Steel Needs Cold Galvanising
Steel is widely used in construction, manufacturing, and engineering due to its strength and versatility. However, it has one major weakness - corrosion. When bare metals are exposed to moisture, they quickly develop rust, which weakens the material and reduces its durability. Cold galvanising helps prevent this by forming a high zinc content barrier that protects new galvanised metal and galvanised metal structures from deterioration.
Why Use Cold Galvanising Aerosols?
Applying a zinc galvanising spray is essential for maintaining the integrity of galvanised metal. Unlike hot-dip zinc galvanising, which requires high temperatures, cold galvanising is a quick and easy way to protect steel surfaces without the need for specialised equipment.
At Promain, we supply high-quality cold galvanising aerosols that provide superior protection against corrosion. In addition to spray paint, we also offer ideal repair coating solutions like brush-applied galvanising paint, perfect for touch-ups on existing galvanised surfaces. Every product we stock is sourced from leading manufacturers to ensure excellent protection and durability.
The Benefits of Galvanised Paint
Galvanised paint, often referred to as zinc galvanising spray, provides long-term resistance to rust by forming a sacrificial anode barrier. Some key benefits include:
- Long-Lasting Protection – Shields galvanised metal structures from corrosion, even in harsh conditions.
- Quick and Easy Application – Available in spray paint form for touch dry coverage.
- Cost-Effective – Provides strong protection without expensive hot-dip galvanising.
- Versatile – Ideal for bare metals, new galvanised metal, industrial machinery, and decorative finishes.
Whether you're protecting steel, fences, machinery, or galvanised metal structures, our cold galvanising solutions ensure long-term durability.

Selecting the right cold galvanising aerosol depends on the application and level of protection required. At Promain, we offer a selection of premium-quality products, including:
- Zinga Zingaspray – A highly effective zinc paint for metal, offering excellent cathodic protection. Ideal for touch-ups and full metal surface applications.
- Rustoleum Hard Hat 2185 1085 Galva Zinc – A professional-grade cold galv spray providing superior adhesion and corrosion resistance.
- Rust-Oleum High-Performance Comfort Grip – Enhances galvanized spray paint application by offering better control and reducing hand fatigue.
Each product is designed for durability, ensuring that your galvanising paint continues to protect surfaces long after application.
How to Apply Cold Galvanising Aerosols
Applying a cold galvanising spray properly maximises its corrosion resistance. Follow these steps for the best results:
- Clean the Metal – Ensure the surface is free from grease, dirt, and light rust.
- Shake the Can – Mix the zinc galvanising spray thoroughly for an even protective coating.
- Apply Additional Coats – Spray from a suitable distance, applying smooth, even layers.
- Allow Drying Time – Wait for the first coat to become touch dry before adding additional coats.
- Final Check – Inspect the coverage to ensure full rust protection.
Regular reapplication keeps galvanised metal structures in the best condition, preventing long-term corrosion damage.
Where Can Cold Galvanising Sprays Be Used?
Cold galvanising aerosols are widely used across industries for excellent protection against corrosion:
- Construction – Ideal for steel beams, scaffolding, and framework.
- Automotive – Protects car chassis, exhausts, and underbody parts.
- Marine – Shields boats and ship components from saltwater exposure.
- Agriculture – Prevents rust on farming equipment, gates, and fencing.
No matter the industry, a cold galvanising spray is an ideal match for protecting galvanised surfaces from wear and tear.
FAQs About Cold Galvanising Aerosols
Is cold galvanising spray effective?
Yes! A zinc galvanising spray forms a protective coating that prevents corrosion, making it perfect for galvanised metal structures, bare metals, and decorative finishes.
Can I apply cold galv over rust?
For best results, remove light rust before applying cold galvanising. A clean, dry surface ensures maximum adhesion and long-term protection.
How long does cold galvanising spray last?
When applied correctly, a cold galvanising spray offers years of rust resistance, especially in moderate conditions. Regular maintenance enhances its effectiveness.
