This is a completely safe stone blasting cleaning system for a wide range of stone surfaces.
The Jos system was introduced to the UK more than 20 years ago and it can remove lime and cement based paints, paint residues, old oil based paints and limescale without eroding or cracking the structural damage of a building or object.
Jos-Torc uses a mixture of air, a fine inert powder and very little water to gently remove paints, dirt, graffiti, fungi and other materials without damaging the substrate.
This method of cleaning is suitable for cleaning oxidation from bronze, brass, copper or aluminium. This system creates a gentle swirling vortex with low air pressure, little water and a safe inert fine granulate.
