1. temporary (sacrificial) coating is applied on the surface.
Once a surface treated with a temporary coating has been vandalized, the graffiti and the underlying sacrificial layer can simply be removed with a hot water high pressure washer.
This method is very environmentally friendly. The graffiti paint breaks into flakes that get trapped in the cooled down wax and turn into a special plastic membrane that can easily be removed with plain water. The dirty cleaning water can without any concern be allowed in the sewer system or into the soil.
A new coat is applied on the affected areas to achieve again full protection.
The choice of the appropriate surface protection depends on the physical properties of the construction, the risk situation (e.g. busy street, bus stop in front of the door) and your individual requirements.
