The new BMG-780RS ULTRAPRO Remote Control Grinder is the ideal machine to prepare surfaces prior to new coatings, like removal of old coatings or adhesive residues, to smooth or flatten concrete slabs including curled expansion joints, or to just simply remove unsightly surface imperfections. For decorative concrete applications, it is an ideal system for polishing concrete to a high shine or restoring old slabs for newer architectural finishes. The floating shroud with brush skirt is an added feature for those types of processes. The unit also comes standard with a weight kit for proper weight distribution during grinding and polishing.
