"This sealed concrete stripping brush is the most aggressive of all the floor buffer scrub brushes that we have to offer. It can be used to remove the heaviest of soils from unsealed concrete floor that can be found in automotive repair shops, gas stations, and around any commercial/industrial setting. All you'll need is the proper floor degreaser and a 1.5 horsepower floor buffer. The 20\" 175 RPM floor machine is more than powerful enough to accomplish these tasks.\r\nAnother task this 46 grit impregnated brush can be used for is the stripping of finish off of a sealed concrete floor. This can be accomplished with the same buffer linked above, but you'll need to use the proper floor stripping solution for your particular situation. We offer this same sealed concrete stripping brush with 1\u00BE inch bristles, in a 13\", 15\" &amp; 17\" size, if this brush does not fit your needs."^^<http://www.w3.org/2001/XMLSchema#string>
