Reverse graffitis refers to images and messages when they are applied on polluted surfaces with cleaning methods. Therby an image develops through the removal of pollution or paint.
This method can be used to beautify unsightly facades or floors. But you can also apply targeted advertisement messages with it.
With a template and the special vacuum blasting machine of systeco, these "negative images" can be applied fast and eco-friendly to each surface.
Only small reverse graffiti can be created with the template. However, you can also create very large reverse graffiti, such as on this dam. The artwork "Fisch-Reich" is by Klaus Dauven and was created in 2012. Only part of the surface is cleaned. Of course, this requires a lot of skill and good spatial awareness.
The use of vacuum blasting technology would not make sense here. The area is simply too large and access is very difficult.
