3M Tan Burnish Pad 3400 produces a good gloss while removing black marks and scuffs, and is ideal for harder finishes. The pad is made of polyester fibers in an open-textured non-woven construction which resists loading and clogging. The washable, reusable pad is conformable, offering high pad-to-floor contact. Fine polishing particles are distributed throughout the pad to deliver high-quality performance over the life of the pad. For use with cord-electric, battery-electric, or propane-powered ultra-high speed floor machines operating at 1500 rpm or greater. The pad is reversible.
