Ecological facade cleaning

Yes, it works very well if you use the right method. The high-pressure hot water variant works in the same way as the manual method with a chemical agent for graffiti removal. The chemical solution is applied to the surface to be cleaned and then removed with a high-pressure jet. The method 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 façade. Depending on the surface and type of soiling, the pressure is adjusted. The disadvantage of this method is that components of the plaster can be exposed. Often, distinct shadows appear 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.

Facade cleaning with high pressure and chemicals are not ecological. These two methods consume too many resources and pollute the environment with toxins and additional water consumption. There is a simple and ecological solution to this problem, 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, both indoors and outdoors, can be cleaned in a residue-free and environmentally friendly way. Everything remains in a closed cycle. What remains are clean surfaces and gleaming facades.

The use of chemicals is a common variant of façade cleaning. With such chemical agents, you can certainly lend a hand yourself. But be careful! The manufacturers usually promise that the cleaning agents are harmless and biodegradable. Unfortunately, this is not always true. As a rule, the use of chemical agents is only suitable for small areas. In a final step, the surface has to be re-washed and that is where the next problem arises. The chemical solutions are usually quite aggressive, and if handled incorrectly, these methods can quickly cause damage to the substrate.

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

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.
