U-Sand changes everything about floor sanding.Rip and strip finishes on existing floors with ease. Cuts through urethane efficiently and leaves the wood clean and ready for a new finish. Sands in any direction without damaging the grain pattern, and is the best machine for antique floors as it removes far less material than drums so your floors last longer. Far easier to use than traditional drum sanders: change hook and loop grit disks in seconds, vacuums dust out of the way as you go, edge and buff with the same machine, floats easily as you make your passes.
