We were the main specialist exterior cleaning contractor used for cleaning of St Marys, Tramadog Gwynedd a Coade stone lynch gate.
For this project we used Stonehealths TORC system.
We are now using Restorative techniques “Vortech” which we find a massive improvment on the Stonehealth system
The TORC/Vortech system creates a gentle swirling vortex using a mixture of low air pressure, little water and a safe inert fine granulate.
There are variations in the type of abrasives used depending on the type of substrate being cleaned.
The key characteristics include: Particle size (maximum size and size distribution) Shape (rounded, angular etc.) Density Hardness (value expressed in Mohs)
