A Comprehensive Guide to Zinc Galvanising Spray

What is Zinc Galvanisation?

Zinc Galvanisation is a coating that provides corrosion protection; it is an effective and cost-efficient way to protect metal surfaces from rust and corrosion.

What does this mean?

Using Zinc Galvanisation Spray means that there is a protective coating on you metal and iron steel objects and structures. This is achieved by spraying atomised particles of molten zinc onto the metal surface using either a handheld applicator or a special flame. The resulting zinc coating offers remarkable resistance to corrosion and is ideal for use in challenging environments like marine, industrial, and other areas with harsh atmospheric conditions. The spray galvanising process helps to ensure the longevity and durability of steel and iron objects and structures.

Two Types of Galvanisations:

There are two main types of zinc galvanising, the Zinc Spraying Process, and the Hot-Dipped Galvanising. The Zinc Spraying Process contain a high percentage of zinc dust, while Hot-Dipped Galvanising contain a mixture of zinc and aluminium. The purpose of the Zinc Spraying Process is different to the traditional hot-dipped zinc galvanising, the former offers a thorough protective coating while the latter chemically bonds with the metal.

Zinc Galvanisation Spray

Zinc Galvanizing Sprays are special types of aerosol spray paint cans that contain the zinc-based paints which provide the corrosion protection to the metal. The sprays are commonly used for touch-up work on galvanised surfaces where welding has been performed or the base metal has been exposed.

Where Zinc Galvanising Spray Can be Used

  • Windmill Towers
  • Chemical, Fertiliser and Cement Industries
  • Oil Refineries
  • Plants with Pipelines
  • Power Plants
  • Bridges and other marine applications
  • Transformers Tanks
  • Automobile Radiators
  • Solar Structures
  • All steel infrastructure exposed to Atmosphere


Zinc Galvanising Sprays is compatible with most metal and surfaces. Generally, Zinc Galvanised Spray process protects metal for 8-10 months. However, this is dependent on the surrounding atmosphere. The protection duration will be less if the metal is exposed to salty atmospheres by coastal areas.



Zinc Galvanising Spray increases the life of the metal

Gives the exposed metal good finish

Economical compared to the Hot Dipped galvanising process

Easy to use and apply

Easily availability

No special skills required


Short term protection in comparison to the Hot Dipped galvanising process.

Surfaces must be cleaned of grease, oil and rust in order to use Zinc Galvanising Sprays as such factors could disrupt the coating.

Aerosol Spray so is harmful by inhalation and highly flammable.

Though it is corrosion resistant and has longevity it is still subject to chipping and other damages.

In conclusion, Zinc Galvanising Sprays are a useful tool for protecting metal surfaces from corrosion. They are easy to apply, provide effective protection, and are widely used for touch-up work on galvanised surfaces. By choosing Zinc Galvanising Spray individuals and businesses can ensure the longevity and durability of their metal objects and structures.
