Introducing concrete prep Plus from Diamabrush By Malish. The ultimate concrete prep tool for hard-to-prep surfaces. The Diamabrush By Malish concrete prep system has been extended to now include concrete prep Plus. This new heavy duty prep tool is ideally suited to prep floors for an application of paints, epoxies, or stains. The concrete prep Plus will also remove a thin layer of paint or epoxy. Concrete prep Plus is specially designed to last up to 3 to 4 times longer (up to 50,000 sq.Ft.) than our standard concrete prep tool. With its more durable cutting blades, the Diamabrush By Malish concrete prep Plus allows prepping concrete floors to take place in a fraction of the time. Like all products in the Diamabrush By Malish system, the concrete prep Plus tool can be used on your existing floor maintenance equipment. This particular tool is designed to handle the pressure and weight of heavy down pressure machines like large ride-on scrubbers and heavier duty floor machines and buffers. Concrete prep Plus is the first step in a complete concrete floor preparation system. Following the use of concrete prep Plus, six (6) polishing tools may be used (from coarse to fine) to achieve the level of gloss your application requires.
