Another exterior sandstone cleaning and treatment, carried out by our team this week, on about 200 m2 in south London area.
🚫NO PRESSURE WASHING & NO DOFF SYSTEM🚫
This system can damage the stone by opening the stone porous, in this way the stone will get dirty very quickly.
For this reason, we use only machine diamonds and water, so the whole process is natural!
🚫NO CHEMICALS ARE INVOLVED🚫
In the intermediary phase, we’re using diamond cleaning for the sandstone. The Chemspec Company has one of the best diamonds in the market nowadays, especially the metal bond diamonds.[envira-gallery id=”945″]
In the small video footage below, we can see how we’re performing the sandstone cleaning with these metal bond diamonds.
