The more porous the surface is, the more difficult the graffiti removal.

Porous and unprotected surfaces, such as many kinds of natural stones as well as sandstone, travertine or limestone, but also concrete.

The graffiti paint penetrates through the many and usually deep pores and sinks deep into the substrate.

Color shadows in the substrate after graffiti removal. Removal of color shadows usually requires considerable effort.


The more closed (smooth/polished) a surface is, the easier the graffiti removal.

Substrates that are neither porous nor unprotected. E.g. tiles or glass, but also metal.

The graffiti paint doesn't penetrate deep into the surface. It can easily be removed. There are usually no color shadows left on the surface.

Helpful Hints and Tips

Graffiti should always be removed immediately! Graffiti on a house wall tend to invite further defacements. Once illegal graffiti is immediately erased, the appeal to sprayers is lost and they quickly lose interest in the graffiti-free surface. Copycats will no longer be encouraged because the inhibition to deface a clean wall is greater than with an already vandalized one.

For the following three reasons vandalized areas should not be painted over without first removing the graffiti: lack of breathabilty of the facade, „bleed-through“ of the painted-over graffiti and poor carrying capacity (spray paint) due to the existing graffiti. „Negative shadows“ of the smearings might still be visible after cleaning. However 98% of the color shadows can usually be eliminated.

Once the graffiti has been removed, the cleaned surfaces will appear brighter than the uncleaned ones since cleaning products and the pressure washing, where required, also remove older environmental pollution.

Graffiti Removal Procedure

The removal of graffiti from unprotected surfaces is achieved through the use of a special graffiti remover selected for the specific surface. The graffiti is then rinsed off the cleaned surface, usually with high pressure hot water.

Any remaining color shadows are then treated with a special shadow remover or a bleaching agent.

All types of spray paints and varnishes, feltpens, asphalt, tar and oil can be removed this way from natural stone, brick, marble, concrete, metal, fired clay, glass, plastic, PVC, sandstone, slate, terrazzo, wood, tiles, plaster as well as from all kinds of smooth, raw and porous surfaces.
