At Epoxy Floors North we feel that prep is the single most important part of the whole process. We have state of the art diamond grinding equipment to handle any size project. We diamond grind every floor new or old. We would never use a power washer in your garage that could damage garage cabinets, base boards and walls. The diamond grinding machine is attached to a vacuum that collects 99% of the dust. The floor is now ready to be caulked and divots repaired.
