The new Blastrac BMG 435 grinder and polisher is a three-headed planetary machine designed for multi-purpose use on concrete, terrazzo, natural stone and wood surfaces. On concrete, the BMG 435 cleans and prepares the surface, levels uneven areas, removes coatings, cleans glues and mastics, and polishes. On terrazzo and natural stone, the grinder cleans dirt, grease and scuff marks, and grinds and polishes. On wood, it cleans paint and coatings, and sands the surface for refinishing. The machine’s planetary system results in easier handling and smoother grinding with fewer swirl marks. www.blastrac.com (800) 256-3440
