The 3M Niagara 7200N-19 Black Stripping Floor Pad is the industry standard for aggressive wet stripping of old, soiled floor finishes and sealers. It is specifically engineered to maintain consistent high performance throughout its entire life by distributing abrasive minerals evenly throughout the non-woven fiber web. Key Performance Features - Heavy-Duty Stripping: Quickly removes two to three layers of old finish, sealers, and stubborn contaminants to prepare the floor for refinishing. - Uniform Mineral Coating: Abrasive particles are bonded throughout the pad—not just on the surface—ensuring the same level of aggressiveness as the pad wears down. - Anti-Clogging Design: Features an open-textured, non-woven construction that allows stripping solutions to flow through, reducing "loading" and ensuring constant floor contact. - Eco-Friendly Certification: Green Seal Certified for reduced environmental impact; the Niagara line often uses recycled PET plastic from water bottles in its construction. Specifications & Machine Compatibility - Diameter: 19 inches (483 mm). - Thickness: 0.75 inches nominal. - Machine Types: Compatible with most low-speed automatic scrubbers and rotary floor machines. - Operating Speed: Designed for conventional speeds between 175 and 600 RPM. - Surface Compatibility: Ideal for most hard floors, including vinyl tile (VCT), concrete, marble, and terrazzo. Usage & Maintenance - Application: Use exclusively with water-based stripping solutions for finishing removal; it can also be used with heavy-duty cleaners to scrub bare concrete. - Maintenance: To maximize lifespan, pads are washable and reusable. Rinse with a pressure spray nozzle or soak in detergent to dissolve caked finish before drying. - Double-Sided: Designed for use on both sides to maximize the utility of each pad.
