Both aggressive and very conformable, 3M™ Brown Stripper Pad 7100 can be used in wet stripping, dry-foam stripping and deep scrubbing processes, performing well even on bumpy, irregular or worn floors. When used in a heavy-duty scrubbing process, the 3M™ Brown Stripping Pad 7100 will remove up to 2 to 4 coats of finish in preparation for refinishing. With appropriate cleaning chemicals, it can be used to clean heavily soiled hard-surface floors such as concrete. The pad is uniformly permeated throughout its open construction with resin and mineral abrasives, providing impressive performance and a long, useful life.
