Facades made of natural stone, clinker or concrete not only protect our buildings from the weather, but also shape their appearance. Therefore, when it comes to protecting, repairing or restoring the facades of buildings, high demands are placed on both the technical and the visual appearance. When cleaning stone and brick facades, the top layer of the material must not be removed or damaged, which can cause the material to become impervious to moisture, damaging it irreparably over time. JOS technology is particularly suitable for cleaning such surfaces, as air, water and abrasive are mixed in a nozzle, which blows the mixture at low pressure (0,5 to 4 bar) against the surface to be cleaned. A rotating vortex is formed in the conical jet which gently cleans the surface to be treated without damaging its underlying structure.
