Graffiti protection is the term used to describe preventive measures with the aim of enabling the complete removal of disfiguring paints and varnishes from component surfaces without damaging the component surface. In particular, graffiti protection systems help to prevent the entry of paint into component pores. A distinction is made between
- separating layer formers (coatings): The graffiti protection system completely covers the component surface, creating a separating layer between the surface and the colorant. Graffiti is removed using chemical agents that are tailored to the respective system. Interface formers are particularly suitable for touch-ups and the targeted visual enhancement of the surface.
- Impregnating systems: Due to its oleophobic properties, the protective system prevents the penetration of dyes, especially into the pore area. The component surface develops a dye-repellent effect. They are particularly suitable for smooth, poorly structured surfaces and are usually permeable to water vapour.
In addition, a distinction is made between both systems and
- sacrificial systems: systems that have to be partially or completely replaced after graffiti has been removed.
- Non-victim systems: Systems that maintain their effectiveness after graffiti removal.
As a coating, they are applied in several layers and are comparatively resistant to weather influences. With the addition of pigments, they can also be used for façade design.
