I put armorpoxy on my floors first right after shop was built, put lift in, cabinets, racks, lathe, drill press, welders, etc all after floor was done and didnt scratch or mess up the floor any. For the lift I just cut some of the cardboard box (really thick) that some of it was covered in and put on the floor when I stood up the columns and walked them in place on the cardboard, then just slid it out. I dont intently drag metal or sharp heavy items across the floor but I dont baby it either. Next week the floor coating will be one year old, and I will put the same stuff on my new add on as soon as I can.
