More elaborate, decorative polished concrete can range from $5 to $10 or more.
What Are The Factors Affecting the Cost of Polished Concrete?
Concrete polishing equipment comes in various sizes.
Hand Grinders – For tough to reach areas near walls and columns, hand grinding is the best option. The process starts with course pads to break through the top layer. Then numerous steps in the process are used to grind and hone the surface.
Small Upright Machines – Small is a relative term when referring to polishing equipment. A small machine can be 300 lbs. Each machine also has a high powered industrial dustless vacuum. Both the polisher and vacuum can be powered by a portable generator.
Each polisher uses different diamond grinding pads. They start with course pads ranging from 25-50 grit. Then the pads are changed to 50-100 grit, 200, 400, 800, 1500 and 3,000 grit.
Polishing concrete is a multi step process working from course pads to finer ones.
A 300 lb machine will not produce the same level of polish as a large industrial machine. The additional weight makes a significant difference in outcome.
Small areas like basements or garages can benefit from the Grind & Seal finish. Frequently what starts as a polishing requirement ends with a grind & seal finish, an overlay or epoxy.
Large Upright Machines – These can be 1,000 lbs or more. They are used primarily in commercial areas. Restaurants, Retails Stores, Offices, Showrooms and warehouses are popular uses.
