The Perfect Touch-Up Solution for Galvanized Steel.
Traditionally, there were two types of paint for galvanizing, i.e. paints used on galvanized steel – these were wet paint and powder coating. While each of them had their undoubted strengths, they also had their weaknesses.
In the case of wet painting, for example, wet paint will eventually fall off with the passing of time. To touch it up involves taking all of the old paint off, cleaning it down and repainting from scratch. This is a hugely time-consuming and onerous job, with a financial cost to match.
With powder coating, on the other hand, there are no solvents involved so it was widely regarded as being the best way to go. The problem, of course, is that powder was never designed for galvanized steel. This means that if it gets damaged, trying to touch it up looks dreadful from an aesthetic point of view.
And similar to wet paint, you need to take it all off and start again – not to mention the fact that it requires a machine to touch up all the damaged areas.
So is there a better alternative when it comes to touching up?
Thankfully, there is. Galvacoat® is a tough, single application polyurethane topcoat that’s specifically formulated to adhere to non-ferrous metals such as zinc. It is a highly cost-effective and efficient paint system that delivers perfect adhesion to hot dip galvanized steel.
The big benefit of Galvacoat® is that it can be touched up on site without having to take the old material off, making it quicker, cheaper and much more efficient.
Achieving great adhesion to hot dip galvanized steel
It can be very hard to get paint to stick to galvanized metal – and with good reason. When zinc comes out of the ground, it reacts to the atmosphere by trying to cover itself in salt for protection. If you paint the top of zinc, the same thing happens and salt forms under the paint.
The flexibility to cope with any environment
A major benefit of Galvacoat® is that it can be altered to suit the specific needs on site. For example, in a coastal environment, high acidity environment powder coating mightn’t be able to meet the requirements of the location – but Galvacoat® can be chemically altered to meet the demands of any physical environment.
Another strength of Galvacoat®, in terms of flexibility, is that you can paint it on site – unlike powdered systems. This is particularly important when you are looking to deliver a great aesthetic result, e.g. in a company’s public headquarters or a public-facing building.
Cleaner application every time
Galvacoat® application is tightly controlled, so it goes where you want it to go. This really comes into its own in situations where there may be mechanical damage to painted steel. As Galvacoat® is a wet paint system, it can be applied by roller or brush, giving greater accuracy and less mess than a spray system.
The bottom line is that when it comes to touching up galvanized steelwork, there’s only one answer – Galvacoat®.
