bare concrete floors and printers that need "dust free" environment DONT MIX. bare concrete from the day is totally dry........WILL MAKE DUST FOREVER!!!!!! this is why in my shop, before i moved anything to the floor, i put down a 2 part epoxy 100% solids paint. is a lot of work, but the end results are fantastic. this 5 years later.
sweep with a fine broom, damp mop with a mild detergent, and you can eat off this floor.
