The new Diamatic 735 Propane Grinder (LP) is an ideal machine for heavy commercial applications of grinding, concrete floor polishing and preparing surfaces. Offered in the standard 28″ working width or the XL version with its large 34″ working width. These workhorses prepare surfaces for new coverings, eliminate old coatings or adhesive residues, grind and polish or flatten concrete slabs, including curled expansion joints. If you want to just simply get rid of unsightly surface flaws, this is the machine for you. For ornamental concrete applications, it is an excellent system for polishing concrete to a high luster or restoring old pieces to newer architectural finishes.
