I've been doing alot of basement concrete floors latley with my 12" redline spinner and charging 100.00 per hour which seem right to me. Was wondering what is fair pricing for spraying microban after?

Hey Captin, .10 for microban thats just what I was thinking and 3mbrandscotchgard at .15. Had a basement the other day, they had kept there animals down there all day every day, what a mess. Treated the spots  with urine treatment then pressure washed it with hwe and liquid 90, then sprayed it all down with 2 gallons of microban. I think I got most of the smell out.
