The Mercury 2104 is a stiff poly scrub brush with a 19-inch block that spreads its bristles to cover roughly 21 inches, fitting most 21-inch rotary floor machines. The gray .028-inch polypropylene bristles are aggressive enough to scrub ground-in soil and strip finish from hard floors, yet gentle enough to avoid damaging the substrate, making this a go-to brush for custodial teams maintaining large tile, concrete, and terrazzo areas.
