Inquiry (采购产品): mechanics pit I have a mechanics pit in my automotive garage. It is saturated with grease. What kind of prep can you do to remove the grease and chemicals from the concrete floor and walls of the pit. I saw that shotblasting can be used, but what about the vertical walls of the pit. I want to coat the concrete with an epoxy or urethane product for easy cleanup. **** Hidden Message ***** Ryan Bowman ON K0E 1T0 CAN Company: Bowman Auto Repairs E-mail: bowmanator@hotmail.com **** Hidden Message ***** bowmanator@hotmail.com
