Never even seen a diamond brush system for a 17'' rotary machine so I wondered what they are capable of? With say 42kg of weight spinning at around 150rpm to 200rpm how aggressive are they for removing paint/bitumen off a very rough and riven York sandstone. I get a few enquiries for York stone that has been found under carpet and concrete and really need a lot of cleaning - I am reasonably familiar with the cleaning by chemical route but wondered how far a brush system would go for restorative cleaning via water and just an alkaline or acid wash for cement residue as opposed to a planned maintenance clean in a commercial setting.

Diamond Brushes are fantastic! I have done extensive testing on them over the last couple of years! The problem is we cannot get them to work on all stone! They work well on most stone but this is not their most important application they have more important uses.
So you may ask why haven't we started selling them? The reason is simple! They are in their current form too expensive to stock and retail and that is what we are currently trying to solve! Too many people see something and just jump in and then realise the problems and pitfalls. Tiling Logistics Ltd do the R&D first and try to solve problems before bringing items to market. I do have enough stock to supply you with some though if your desperate. Give me a ring later today and let me know which grits you want to try from 30, 60, 120, 225, 400, 800, 1500, 3000, 5000, 10000 or 15000.

Which Stone do you have problems with the Brush working on Kevin?
I am sat on the fence a little with your comment..."they work well on most stone, but this isn't their most important application".
I am not too sure that this is what you mean.
Their intended use is brush finishing to Marble & Limestone and final stages of Bush Hammering...but as this is a cleaning Forum, I would argue that the IMPORTANT use here is cleaning...and I think they are the best thing since sliced bread for cleaning stone. (Meanwhile, over on the Bush Hammering forum, things are very different!!)
What problems have you come up against?
Obviously, stone finish would be taken into consideration. You wouldnt want to use an abrasive brush on a polished floor, however, on slate and sandstone, you would struggle to find anything better.
On the cost side of your post, my brushes start at £20 for silicone carbide and £40 for the diamond brushes. Thats not too bad....oh and we also do the R&D on our own floors before putting on the market. Very important!
