Ecological graffiti removal

Graffiti removal with high pressure, chemicals and water are not ecological. These methods consume too many resources, pollute the environment with toxins and additional water consumption.   

We have found a simple and ecological solution for exactly this, which we and our customers are completely enthusiastic about. We have turned pressure blasting on its head and developed vacuum blasting. It works without high pressure, without water and without chemicals. Almost all surfaces and substrates indoors and outdoors can be cleaned without leaving any residues and in an environmentally friendly way. Clean surfaces and radiant facades are left behind.

Cleaning with chemicals is a common variant of graffiti removal. Special graffiti removers are available in specialised shops. You can use them yourself. The graffiti remover is applied to the graffiti. The whole process is usually only suitable for very small graffiti. In a final step, the surface has to be re-washed and this is problematic. Since the solutions are usually quite aggressive, the process can quickly cause damage to the surface if handled incorrectly.

But there is another way. With vacuum blasting from systeco, graffiti removal is done completely without chemicals. The surfaces are cleaned without leaving any residue and are simply clean afterwards. 

Yes, this is possible. The high-pressure hot water variant works in the same way as the manual method with a chemical agent for graffiti removal. The solution or paste is first applied to the unwanted artwork and then removed with a high-pressure jet. The process can by no means be described as gentle or ecological. On the one hand, the substrate can be damaged, on the other hand, the environment is considerably polluted by this technique. Therefore, according to current legislation, a costly collection of the contaminated water is always necessary, which makes the procedure considerably more expensive. With the low-pressure wet blasting method, a mixture of air and water and possibly a blasting agent is blasted onto the graffiti. Depending on the surface and type of graffiti, the pressure is adjusted. The disadvantage of the method is that components of the plaster are exposed. Often, distinct shadows are created on the walls and facades.

With the vacuum blasting method, only negative pressure is used. However, this method differs considerably from the aforementioned methods. The vacuum sucks the abrasive out of the storage container. In the blasting lance, the granulate is accelerated to approx. 400 km/h and hits the graffiti to be removed. The paint is loosened by the impact of the granulate. The advantage of the method is that it is a closed circuit, as the blasting material is automatically sucked back into the container through a hose by means of negative pressure. The dirt and paint particles are filtered out in a cyclone. The granulate goes back into the circuit. The cleaning system is easy to operate so that it can also be used by non-professionals. Vacuum blasting is also called a minimally abrasive process. This makes it ideal for very sensitive surfaces.

We all want to live in a beautiful environment without smog and pollutants. For this to work, we have to rethink many aspects of our lives. We have to think and act ecologically. The cleaning of facades and the removal of graffiti are a small building block in our ecological system. But every building block is important so that in the end we have a solid house. That is why ecological graffiti removal is so important, so that we waste as few resources as possible and do not introduce new chemicals and toxins into the environment. Vacuum blasting is the only ecological way to remove graffiti in the future.
