Hi,
I have been asked to clean a pavement in a shopping centre.
It is roughly 2000 square metres.
The paving slabs are blackened with grime build up but no chewing gum.
I was going to Jet wash with a rotary attachment.
The Manager doesnt want jet washing because the slabs are laid on sand.
Would a scrubber drier with some sort of chemical work instead?

What about a slow speed rotory fitted with a brush

I totally agree with Jim. Pre wet the stone then apply a High Alkaline Cleaner and allow to dwell. Then use a slow speed rotary machine fitted with soft to medium brush and have someone following with a decent wet vac. You will fly through 2000M2 especially if you have the manpower to put a couple of teams on it. One small word of warning! To be on the safe side I would price in 4-6 Rotary Brushes depending on the finish of the stone ;)

For myself in this situation a free demo is worth its weight in gold ...
Shows the customer you actually know what you are doing at the same time gives you an indication of timing hence price.
As for no jet washing common misconception, why not explain and supply two options? scrubber / dryer or pressure wash with vacuum.

Thanks for the advice guys! :)

I'm with Mike on this one Tim. Just about all slabs are laid on a bed of sand and though the sand between the slabs will need redoing there is no reason to think that the slabs will be dislodged in any way by pressure washing them.
The customer has a misconception about pressure washing or has had a bad experience. I have never seen slabs become problematic because of pressure washing, I have seen any problems become more obvious in the period directly after pressure washing, because the client pays more attention to them then, but he is entitled to request alternative methods.
Good luck

Pressure washing would be my prefered option - I would'nt fancy chasing the scrubber as its only got a short lead - I clean a wedding marquee carpets with a pad and every time I wish I had changed it . I have even thought about taking one of those wheeled plant pot stands for the transformer ???
