Zinc-Rich and Cold Galvanising Paints for Long-Term Steel Corrosion Protection
Zinc-rich and cold galvanising paints are high-performance coatings formulated to protect steel and ferrous metals by delivering sacrificial, cathodic protection. These paints contain a high percentage of zinc in the dry film, allowing the zinc to corrode before the underlying metal. Systems like Zinga provide a cold-applied alternative to hot-dip galvanising and are ideal for use on prepared surfaces without the need for heat. They're widely used for structural steel, fencing, ships, and industrial machinery - especially in environments exposed to moisture or aggressive chemicals. For best results, these coatings are often paired with compatible metal paints to build a long-lasting, multi-coat finish.
To maximise performance, surfaces should be cleaned thoroughly before application. Once contaminants are removed, zinc-rich coatings adhere firmly and create a robust base layer suited to marine, industrial, and outdoor environments. They're also commonly used for maintaining or touching up previously galvanised surfaces, making them a vital choice for ongoing protection of assets such as bridges, railings, and storage tanks. When used on galvanised substrates, these products pair well with galvanised steel paint to ensure compatibility, uniform appearance, and extended durability in high-risk environments.
Zinc-Rich and Cold Galvanising Paints FAQs
What’s the difference between cold and hot-dip galvanising?
Cold galvanising uses a zinc-rich paint applied at room temperature, while hot-dip galvanising requires dipping metal into molten zinc. Cold methods are more versatile and easier to apply on-site.
Can I use cold galvanising paint over rust?
Light rust may be acceptable if the surface is properly cleaned, but full removal is best for long-term performance.
How long does cold galvanising protection last?
Up to 20 years or more, depending on the product, surface preparation, and exposure conditions.
Is cold galvanising suitable for marine environments?
Yes. Zinc-rich paints are widely used on ships, docks, and offshore platforms due to their resistance to saltwater corrosion.
Can I topcoat cold galvanising paint?
Yes, but only with compatible products. Check with technical support to ensure the topcoat bonds effectively to the zinc primer.
What metals can be coated?
Primarily steel and iron, but with suitable preparation, it can be applied to galvanised steel and aluminium.
Can it be applied with a spray?
Yes, both brush and spray application methods are common, depending on the project scale and complexity.
Is it environmentally safe?
Many modern products are low in VOCs and meet environmental safety standards for industrial use.
Can I use cold galvanising for repairs?
Absolutely. It is ideal for touching up or restoring damaged galvanised surfaces.
