Helping To Solve The Problem of Vandalism With Hydrophobic Anti Graffiti Coatings


Graffiti can be an extremely expensive problem to deal with, with the annual costs in the UK alone estimated to be over £1billion. While it is difficult to prevent graffiti from occurring, it is now possible to make sure that the clean up operation is much quicker, easier and less costly, by applying a hydrophobic anti graffiti coating to surfaces at risk of being vandalised.

What Coatings Are Available?

There are numerous types of coatings available to combat graffiti, but they all usually fall into two main types, sacrificial and permanent and while they can both provide a good level of protection, there are some key differences between the two.

Sacrificial coatings

As the name suggests, these coatings sacrifice themselves to allow graffiti to be cleaned away. The sacrificial coating creates a protective layer over the top of the surface, which means that once any graffiti has been daubed on it, the protective layer and the offending paint/ink can be removed by using a jet washer, ideally using heated water to assist the removal.

These coatings will usually be cheaper to apply than permanent varieties, but due to the fact the protective layer is removed when cleaned, the coating will need to be reapplied to the affected area. This makes these types of coating more suitable for surfaces that do not usually have a high graffiti risk.

Permanent coatings 

Again, the name is self explanatory with these coatings, as once they are applied (if done correctly), they should never need to be replaced. Whereas the sacrificial coatings take the graffiti off with them when cleaned, permanent ones create a hydrophobic protective layer that doesn’t allow the paint to form a proper bond with the surface. This means that it can then be cleaned relatively easily with the use of a cleaning agent.

This does result in them usually being a more expensive option, but if used in areas that regularly suffer problems from graffiti, could be more cost effective over a longer period of time.

Additional Properties & Benefits

While there are a number of anti graffiti coatings available, a lot of of them will have similar properties and provide additional benefits to make them a great option to protect buildings and other surfaces.

  • Colourless – in the majority of cases, there will be a need for the surface to retain its appearance and many of the coatings available enable this by leaving a clear finish after application.
  • Additional surface protection – the core aim of the coatings is to reduce the problems associated with the removal of graffiti, but the protective layers can also provide additional protection from UV damage and weathering as well as making it much easier to keep clean from general dirt.
  • Fly poster prevention – as well as protecting against graffiti, some of the available coating options can also prevent posters from sticking properly. This will mean that while someone may be able to apply adhesive to the surface to put up a poster, the poster will then fall off within a short space of time.
