EMERYTOP 400 is an abrasion resistant, heavy duty floor topping. This flowable, natural emery aggregate floor topping produces a longlasting and resilient floor. EMERYTOP 400 provides an economical, abrasion resistant solution to very severe and abusive concrete floor conditions where other solutions have failed. EMERYTOP 400 uses polyhederal shaped isostructures of emery as its primary aggregate base. Our natural emery aggregate contains nature's highest content of aluminum oxide and ferric oxide for unsurpassed toughness. This unique aggregate has a hardness (Mohs scale rating) approaching that of industrial diamonds. EMERYTOP 400 produces a dense, cohesive mass that is rust-free, chemically resistant, and results in a thick floor surface for maximum abrasion and impact resistance
