Whether it has been spray painted onto coated or uncoated metal surfaces, graffiti vandalism is an eye sore and needs to be cleaned quickly.

Where do you find graffiti on metal surfaces?

Metal surfaces may not be as commonly vandalised as stonework, brick work and masonry surfaces but there are still plenty or locations where you will have no doubt seen graffiti vandalism strike in Glasgow including:

  • Garage Doors
  • Metal Shutters
  • Trains
  • Railway Bridges
  • Tunnel Walls
  • Metal Fencing
  • Gates
  • Commercial Vehicles
  • Industrial Units
  • Portacabins

Because metal is non-porous, it is easier to clean than brickwork or wood. The first thing you need to find out is whether the metal is coated , uncoated or galvanised.

Coated Metals

Powder coated metals and factory painted metals have to be cleaned carefully to ensure that you do not damage the protective layer. Metal coatings are applied to protect the metal from weathering corrosion and rust. If you try to use a pressure washer or scrub clean the graffiti paint from a coated metal surface, you run the risk of scratching and revealing the base metal to the elements – this will result in far worse problems in the future.

Uncoated Metals

Chrome and anodized metal surfaces can be sensitive to pH changes and graffiti paint can cause the surface to change colour. Cleaning agents that have a high alkaline or acid base level can further damage and discolour the surface.

Galvanised Metals

Galvanised metals use a coating of an additional layer to protect the primary metal from rusting. The outer layer is usually quite thin and most galvanising layers are made from zinc. Galvanised metals are cheaper than stainless steel so are actually quite common. If you use a pressure washer to try and remove the graffiti paint, you run the risk of stripping away the galvanised zinc layer and cause the metal to rust over time.

How to remove graffiti from painted metal safely

At Balmore, we have always invested heavily in the latest in cleaning technologies. And for cleaning graffiti from metal, we have two completely different solutions for graffiti removal that can be called upon based on your unique situation.

Dry Ice Graffiti Removal

This non-waste cleaning method can be used in many different industries across the UK and uses 3mm carbon dioxide dry ice pellets to clean graffiti paint. The dry ice pellets return to a gas state upon impact with the cleaning surface, and leave no residue. This offers an invaluable benefit for cleaning services that need to contain any pollutant excess that is removed from the source material and also in the environments that the system can be used in.

How does Dry Ice Cleaning work?

Dry Ice Cleaning can remove contaminants in three ways:

1 – Speed
2 – Thermal Effect
3 – Expansion

The dry ice pellets are propelled at incredibly high speed by compressed air through a controlled nossle. Upon impact with the cleaning surface, the thermal effect of the dry ice hitting the contaminate loosens any adhesion that the staining may have. The expansion of the dry ice as it turns into a gas allows it to expand 800 TIMES its original size which helps to lift the stained contaminate from the surface that is being cleaned for a powerful yet residue free cleaning result.

DOFF Steam Cleaning Graffiti Removal

Doff Steam Cleaning is a stone cleaning system that uses super heated steam with temperatures reaching up to 150ºC. Controlled with a variable nozzle pressure, it can remove carbon staining, paint and biological matter from metalwork without damaging the substrate.

Doff Steam Cleaning is a modern marvel in cleaning technology. It is safer to us on delicate sandstone unlike pressure washing as it does not use brute force to clean surfaces. It achieves far better results without damaging the material beneath.

Balmore Contracting have been operating since 1989 and in that time, we have constantly reinvested in our team and our equipment to ensure that we really can provide you with a full cleaning service. We are one of only a few companies fully equipped to use DOFF Steam Cleaning for stonework whilst our difficult access specialists truly leave no corner uncleaned.

Through all of our cleaning services, we are dedicated to offering the very best in cleaning service and that means that we use the right chemicals on the right materials and do not finish a job until it is cleaned top to bottom.
