The orbital floor sander recommended by Verathane works very well for the homeowner. WE recently put in a hardwood floor in for the first time and used one. WE did great. So you Just Do It. Start out with a fine grade of sand paper, and after a minute or two when you get the feel of it, go to a larger number for a faster job, then finish with a fine grade. WE used real wood not engineered wood. Ask for the direction sheet. or call verathane. Donna You cant screw up if you keep it moving.
