ZINCFIX®
Original
ZINCFIX® Original is a two-component, solvent-free, zinc-rich amine-cured epoxy developed for the repair and protection of damaged galvanized and mild steel. Containing 82% zinc in the dry film, it forms a strongly adherent anti-corrosive coating that helps restore protection where galvanizing has been cut, welded, mechanically damaged or affected by corrosion.
Supplied in a convenient 100 g squish repair pack, ZINCFIX® Original combines accurate small-quantity mixing with modern solvent-free epoxy technology, helping minimise waste while providing a practical solution for localized galvanizing repairs.
Hot Dip Galvanized Steel Repairs
When suitably cleaned steel is dipped in molten zinc at 450°C, a coating comprising of a series of iron/zinc alloy layers, overcoated with relatively pure zinc is formed.
The hot dip galvanizing coating provides a barrier against corrosion but additionally, provides sacrificial protection when the coating is site cut, welded or mechanically damaged.
In order to prevent this sacrificial protection property prematurely consuming the surrounding coating, repair of the damaged area using ZINCFIX® Original is recommended.
Although the medium grey metallic colour of ZINCFIX® Original will stand out on the bright shiny surface of newly exposed zinc, it will blend into a very similar finish once the stable matt grey zinc carbonate film has formed.

Intended Uses
ZINCFIX® Original is specifically designed for the repair of damaged hot-dip galvanized coatings and the corrosion protection of properly prepared steel.
Hot-dip galvanizing provides both barrier and sacrificial corrosion protection. When galvanized steel is site-cut, welded or mechanically damaged, the protective zinc layer can be removed locally, exposing the underlying steel. Leaving these areas untreated can cause the surrounding zinc coating to provide sacrificial protection to the exposed steel, progressively consuming the adjacent galvanizing.
ZINCFIX® Original provides a practical means of restoring protection to these localized areas by applying a zinc-rich epoxy coating directly to the prepared repair.
It is suitable for:
- Repairing damaged hot-dip galvanizing
- Repairing galvanized steel after welding
- Treating site-cut galvanized components
- Repairing mechanically damaged galvanizing
- Corrosion repair on mild steel
- Anti-corrosive priming of steel
- Localized maintenance and repair
- Workshop and site repairs
The product can also be used as an anti-corrosive primer for steel and subsequently overcoated with conventional coating systems.
Typical Applications:
- Hot-dip galvanized structural steel
- Welded galvanized components
- Site-cut galvanized steel
- Galvanized steel repair
- Damaged galvanizing
- Mild steel corrosion repairs
- Structural steel connections
- Galvanized brackets and supports
- Handrails and balustrades
- Galvanized fencing
- Gates
- Steel frames
- Transmission and utility structures
- Galvanized pipes and fittings
- Steel fabrication
- Industrial equipment
- Machinery
- Infrastructure steelwork
- Construction steelwork
- Maintenance repairs
- Workshop fabrication
- Field repairs
- Localized corrosion repair
The compact 100 g pack makes ZINCFIX® Original particularly practical for small repair areas where preparing a conventional multi-component coating in larger quantities would create unnecessary waste.
