This 14 inch tynex scrub brush is used on the IPC Eagle 28 inch ride on scrubbers, and 2 are required. These tynex scrub brushes must be used in a wet environment, and only on concrete or cement. We recommend testing these brushes in an inconspicuous area before scrubbing your entire floor. Great for stripping floor finishes, when used with our environmentally friendly green floor stripper. Each brush has a bristle length of 1-1/2", which is great for stripping uneven floors, because it will hit all the high and low points of your floor, unlike our floor stripping pads.
