This is a demo we did today for a limestone building in Washington DC

It turned out great! I was asking because I walked away from bidding several large buildings because of requirements. If a pressure washer was used maximum pressure can not exceed 250psi. Hose must be rated no higher than 600psi. No acidic chemical can be used. It blows my mind but I can't compete.

Nice demo Mike. Is that the one you sent me a text about? I'm assuming it is. They should be more than happy with those results. I hope you get the bid.

 WOW!!! We came in way under that!

I have no problems working with others to knock out some big jobs and these were huge. They involved concrete. brick with black crustation, limestone and mud-stains on foundations.

I can clean these substrates with a minimum of 1200psi and acidic chemicals. But not without. I did not bid and I am searching for a way to compete on the next bid 

I opened it and checked my computer with Norton, all is good so far. My computer just frozed when I opened it.
