The 3M Brown Stripper Pad 7100 removes old, soiled floor finishes and sealers using water-based stripping solutions. It works in wet or dry-foam stripping processes, or for deep scrubbing, and its conformable design maintains maximum pad-to-floor contact on uneven floors. The washable, reusable pad resists loading and clogging for consistent cut over its life. Sized 20 inches for use with rotary or automatic floor machines.
