Diamabrush by Malish is an excellent tool for a home-owner or contractor to properly prepare concrete for epoxy coatings or sealers. This product accompanied by a common (call for compatibility) floor buffing machine becomes a diamond concrete grinder.
Before Diamabrush your choices were an expensive and cumbersome grinding machine or acid etch. Both have Pros and Cons, both are not easy to use.
Diamabrush will soon be carried by Legacy Industrial, please contact Legacy Industrial at 908-269-8300 for more information and pricing.
