Over the last couple of decades graffiti has become a great problem particularly in the large agglomerations.
It appears almost everywhere - on the external walls of buildings, girders and piers of bridges, underground passages, facilities in parks and roads. About 80% of graffiti is written with paint and marking pens on large walls, very often on historical objects.
A considerable amount of money and time are spent annually on removing graffiti, City Councils have now begun to enforce regulations for keeping streets clean. According some of these regulations, not only the person who wrote the graffiti is responsible for damage, but also the owner of the building on which the graffiti was written and unattended for a prolonged period of time.
The traditional cleaning techniques are based on the use of a scalpel, abrasive dust, stream of fluid, or chemical agents. They may lead to the serious damage of the deeper layers of substrate.
Laser-Assisted Removal of Graffiti
Graffiti is one of the most immediate threats encountered on heritage monuments worldwide, and its cleaning is considered by the entities responsible for heritage protection as one of the most demanding conservation issues. The necessity of methods to completely extract the graffiti paints, safeguarding the original surfaces, was discussed in scientific projects focused on the optimization of cleaning methodologies, as well as on the development of protective anti-graffiti coatings.
Graffiti is, by its nature, a particular overlayer to remove because of the presence of pigments of different color and chemistry, and also because its penetration into the stone bulk is inevitable. Conventional cleaning methods, involving the use of chemical products and mechanical tools, do not completely remove the paint, and at the same time they can be rather aggressive to the stone surface. Lately, laser radiation has been evaluated as a feasible alternative tool for the elimination of graffiti due to its high precision and control during cleaning, as well as the possibility for automated cleaning processes. Recent studies have focused on the determination of optimum laser cleaning parameters and procedures for graffiti paint removal.
Graffiti Removal - Stop losing time and test out laser cleaning!
Laser cleaning is great for removing graffiti.
The laser will quickly heat up the paint layers, which then evaporate away. The substrate remains cool because of its higher ablation temperature, restoring the underlying stone, brick, steel or cement to it’s original glory. And there’s no waste to clean-up afterwards thanks to our HEPA air scrubber and HEPA vacuum system.

Graffiti cleaning by laser
Quick and efficient result without efforts
Graffiti is often removed by using steam or chemicals. The disadvantage of these techniques is the fact that they’re not always as effective as they should. With other techniques, like sandblasting, there is a risk of damaging or wearing down the underlying layer. This forms a problem with softer stone types and historical buildings.
Laser cleaning is very suitable for removing graffiti. The laser beams will quickly heat up the paint layer, which then will evaporate. The underlying stone or concrete layer remains cool because of its higher ablation temperature. So the laser beams will have no effect on the underlying stone or plaster layer. Even on wood or glass, paint can be removed!
When using sufficiently powerful laser sources, the removal of graffiti goes very fast. Depending on the age, the color and the thickness of the paint layer, we are able to clean a square meter full of paint in less than half an hour with our heavy power cleaning lasers.
Thanks to its quick cleaning, laser cleaning is comparable or even better in price to the other techniques, but it has so much better results with a very high positive ecologic impact.
Advantages of graffiti removal by laser cleaning
- Eliminates the use of solvents (climate protection)
- Reduction of grinding and chemical cleaning resources
- Reducing noise in inhabited parts of cities
- Cost reduction
- High productivity of tools
- Reduction of the masking material
- The process can be used safely outdoor (for example masts) and in the locations where it’s not possible to use conventional methods
