Provides the premium performance you've come to depend on from 3M™ surface preparation pads, plus it's even easier to use. It doesn't need a backer pad and it quickly removes the top layers of finish with less clogging during use. With its extra long-lasting scrubbing performance, you'll replace the pad less often, so you'll spend even less time getting your floors ready to shine. Requires only neutral cleaner or water to effectively remove floor finish, preparing the floor for finish application. Lasts longer and performs better throughout the life of the pad. Clogs less and helps reduce labor hours and material costs. Use with auto scrubber, swing machine or rectangular floor machine. Use on coated vinyl tile, marble, terrazzo, concrete and other floor surfaces. Green Seal® Certified.
