The document provides instructions for a 4-step process to polish concrete floors using common cleaning equipment and inexpensive materials. The process involves cutting the concrete with a 200-grit diamond ring, densifying it, polishing it with a 400-grit resin pad, and applying a stain protector. Additional options like staining and exposing aggregate are also described. The standard charge is $2-2.50 per square foot. The materials kit costs $325 through a PCN special offer and allows polishing of approximately 1,000 square feet, yielding $2,000-3,500 in profits.
