Unwanted graffiti and wild stickers, posters and signs cause millions in economic damage every year in Germany alone. A specially developed silicone coating from WACKER can help keep cleaning costs low.
Graffiti artists usually work at night, spraying their often enormous creations – which they refer to as pieces – and their signature emblems – known as tags – on walls, fences and rail cars. They almost always do this without the consent of the property owner, whose only recourse is buffing – the term used within the graffiti scene for removing illegal pieces.
Egg-shell stickers are especially difficult to remove. They are the stickers and posters that often advertise events, and are usually found on relatively small objects like utility boxes and traffic signs.
The Association of German Cities estimates that the damage caused by illegal graffiti and wild posters costs the Federal Republic at least €200 million annually. In the United States, data provided by the Department of Justice indicate the cost of graffiti removal to be some twelve billion dollars per year. One of the most costly practices is known as bombing – when the perpetrator tries to spray as many simple characters as possible in a short period of time, emphasizing quantity over quality.
It follows that public and private property owners are looking for ways of keeping removal costs low. One option for them is a preventive treatment with a protective anti-graffiti system. Developed by Wacker Chemie AG, SILRES® BS 710 is a concentrated active agent for long-term graffiti prevention. At the 2017 European Coatings Show, the Group will be unveiling the product to a wide audience of professionals.
Most anti-graffiti systems form an unbroken film over the substrate to be protected. This film seals all of the surface pores and acts as a barrier between the substrate and the paint sprayed onto it.
This barrier layer keeps the spray paint from entering the pores of the substrate, thus preventing the graffiti from adhering well to the surface and making it easier to remove – the graffiti can then be washed off using a suitable cleaning agent, though both the cleaning method and the cleanser need to be appropriate to the coating in question.
