Graffiti is a growing issue for a lot of businesses and community.
We specialised in providing graffiti management solutions to assist property professionals control, prevent and protect against graffiti vandalism.

Cleaning graffiti off buildings costs billions of dollars annually. Many cities have started antigraffiti programs but vandalism is still a problem. Companies across the globe are attempting to develop coatings to prevent vandals from defacing public and private property.

The coatings being developed can be the paint itself, or a clear coat added on top of existing paint or building facades. Depending on the substrate and the severity of graffiti, different coatings give different benefits and disadvantages.

Types of coatings

Anti-graffiti coatings can be invisible to the naked eye. There are two different categories of anti-graffiti coatings. The first, sacrificial coatings, are applied to a surface and then removed when graffiti is applied. The surface underneath will be left clean and a new sacrificial coating can be applied. The other type of coating are permanent coatings that prevent graffiti from adhering to a surface in the first place.
Newer coatings are made of charged polymeric materials that form a gel on the surface of the building or substrate.

Our Premium Anti-graffiti Coatings

  • Sufficient adherence without damage to substrates
  • Hydrophobicity (water-repellance)
  • Environmentally friendly composition and processing
  • Resistance to UV aging and weathering
  • Good. Low coast cleaning efficiency

Sacrificial coatings

A sacrificial coating forms a clear coat barrier over the wall or surface being protected. If the surface is vandalized the coating can be removed (sacrificed) using a highpressure washer taking the graffiti with it. The coating then must be reapplied.

The materials used to make a sacrificial coating are usually inexpensive optically clear polymers such as acrylates, biopolymers, and waxes. These polymers form weak bonds with the substrate to allow for easy removal.

Semi sacrificial coatings

A semi sacrificial coating known as a safety shield acts as a penetrating sealer on the wall or surface protecting the surface pores. If the surface is vandalized the coating can be particularly removed using a combination of graffiti removal solvent and highpressure washer.

The anti graffiti safety shield is generally reapplied every second attack. While it is possible to use only pressure to remove coating, this will cause additional surface erosion.

Superhydrophobic surface

Permanent coatings are often more expensive than sacrificial coatings, but if used appropriately only have to be applied once. These work by creating a protective surface that spray paint cannot bond to. After the surface has been vandalized, often all that is needed to remove the paint is a simple solvent (toluene) and some manual labor. The underlying surface and the protective coating will remain undamaged.

Some of the types of permanent coatings include those based on polyurethanes, nanoparticles, fluorinated hydrocarbons, or siloxanes. Polyurethane coatings are useful because of their barrier properties. High chain stiffness and high crosslinking density reduces the ability of the polymer to swell and absorb graffiti paint.

Fluorinated coatings are some of the most effective in the field of graffiti prevention. Fluorine is the most electronegative element, meaning that it shows very little affinity for the electrons of other elements. When fluorine is attached to a surface it will decrease surface energy at the interface, minimizing the contact with the graffiti paint.

For the same reason that a Teflon-coated pan repels both water and oil, a fluorinated coating will repel water and oil-based paints. These coatings also have the added benefit of being chemically inert as well as very durable.
