What's a good $/sf for a prep/grind job?
I have a customer that just had a 700-800 sf pole barn built. It has been over 30 days since the concrete was poured and he wants it to be epoxy flaked/coated, that's no problem. The catch is, there are some imperfections in the concrete from the Mason's pour and because of that, the PM running the job is going to cover the cost to grind the concrete and smooth the imperfections back out. Based on pictures I have gotten, the floor doesn't look like it will need anything special, most likley just a simple grind with 18/20 grit diamonds and a little patch here and there and it should be good to coat. Normally my prep price is combined into my overall cost of coating the floor with flakes, but with this situation, I need to provide the PM a price to grind the floor and the customer a price to coat it. I will be renting a machine to grind because I don't own my own yet so that will be a a factor of the costs, but does anyone have any recommendations as to what $/sf they would charge for the grinding. Do you have a general price for that service that you are willing to share. Trying to get an idea of what to charge/ what a typical going rate for that type of service is.
