Designed to recondition the surface of a wood floor (gymnasiums, parquet areas, etc.). With its fine abrasive action, it will smooth the surface of raised wood fibers that are created when using waterbased sealers and finishes. It will deburr, smooth and clean wood floor surfaces between coats to give you adhesion and the resulting level surface needed for that next coat. Redwood[TM] is a 3/8" pad and should be used with a 1" ETC Red pad to drive it.
