3M's most aggressive floor stripping pad, the 3M™ High Productivity Pad 7300, is the best choice for removing four or more coats of finish buildup from hard floors. The stripping pad's open construction allows stripping solution to circulate through the pad, reducing loading. Continuous nylon filaments, uniformly coated with resin and abrasive particles, provide consistently high performance throughout the life of the pad. For rotary and automatic floor machines. For optimum conformability and pad-to-floor contact, the pad can be backed with a red buffing pad. Floor Pads Application: Stripping; Diameter: 21"; Color(s): Black; Color Family: Black.
