Graffiti Control
No chance for graffiti vandals
Whether pictures, writing or symbols, graffiti vandalism ruins the appearance of buildings and facades. Protectosil® ANTIGRAFFITI protects surfaces against such graffiti vandalism: With Evonik’s graffiti control solution, pictures and tags start to run as soon as they are sprayed on, which quickly deters vandals. Moreover, as the paints do not penetrate the fabric of the building and are therefore easier to remove.
Long-lasting graffiti control
Because Protectosil® ANTIGRAFFITI is UV and weather-resistant, the facade is protected against graffiti for many years, despite the sun and the rain – the ready-to-use product can withstand up to ten cleaning cycles until it has to be applied again.
It is not an anti-graffiti coating in the conventional sense – the silanes in the product form a chemical bond with the building’s mineral substrate, allowing them to offer long-lasting protection. This is especially sustainable and cost-efficient, particularly in areas often plagued by graffiti vandals.
Ideal building climate
This is the difference between the long-lasting graffiti protection of Protectosil® ANTIGRAFFITI and what are known as sacrificial layer systems, in which a layer made up of wax, polyurethane or silicones is applied to the mineral substance and needs to be replaced each time the graffiti is cleaned off.
These traditional coatings also seal the surface of the building material, meaning that water vapor cannot pass through from the inside. In contrast, substrates treated with the Protectosil graffiti control product range remain breathable. This ensures that the building substance is not damaged by residual moisture on the inside, while also retaining the natural surface structure and ensuring an ideal climate in the building. Because the product does not contain any solvents, it is not harmful to health and is gentle on the environment.
Protectosil® ANTIGRAFFITI is almost invisible
There is also a visual benefit: Protectosil® ANTIGRAFFITI repels water, oil and dirt, thereby preventing paints, varnishes or marker ink containing water or oil from entering the pores of the building fabric. But that’s not all – because its mechanism of action is barely visible, it has no impact on the desired outer appearance of the building facade. Examples of buildings that have been treated using Protectosil® ANTIGRAFFITI include parts of the Louvre in Paris, the Darmstadt State Theater or Kunstmuseum Basel (Basel art museum).
Evonik offers Protectosil® ANTIGRAFFITI SP as a companion product to this system. This semipermanent graffiti control coating can withstand at least three cleaning cycles, also allows water vapor to pass through and is especially weather-resistant. One example of where Protectosil® ANTIGRAFFITI SP is used as protection is the “CHORUS” marble mosaic in the new subway station serving the World Trade Center in New York.
