concrete_polishing_oregon2Polished concrete is concrete that has been polished with a diamond grinder, then treated with a chemical densifier that makes the surface harder and more stain resistant; and finally polished with progressively finer grinding tools. The grinding tools are usually progressive grits of diamond grinding wheels and diamond polishing pads. Typically, concrete is not considered polished before 400 grit, and it is normally finished to either the 800, 1500, or 3000 grit level. Stains and dyes are often applied to enhance polished concrete as well as other options such as scoring, creating radial lines, grids, bands, borders, and other designs. The process can be used with new or existing concrete floors-including heavily used surfaces. In the process, cracks and joints can be filled depending customer needs and budget.

The Green Solution: Polished concrete is considered a good sustainable design flooring option because it makes use of the materials already present. Most modern buildings are built on a concrete slab; polishing the exposed concrete eliminates the energy and material consumed by applying a floor covering. What’s more, the reflectivity of the polished concrete can reduce lighting costs. For owners and builders it is something to consider when building or modernizing toward a more green solution.

The Benefits: Polished concrete floors are low-maintenance, more durable and easier to clean than many flooring options. Its relatively high coefficient of friction can make it non-slippery. Polished concrete reduces dust mite and allergen problems, and does not support mold growth. Polished concrete flooring is hard wearing and will not chip or dent like softer surfaces such as timber. Mopping with warm soapy water once a week is the only maintenance required.

A concrete floor that has been hardened and polished will have an extremely long life expectancy compared to other flooring. For example, tile may only last 10 to 20 years, but a polished concrete floor properly maintained may give 100+ years of service.

LEED 2009 standards contain guidelines for using polished concrete flooring to qualify for LEED credits.


American Concrete Company’s experienced crews will lead you through the process involved in polishing concrete:

  1. Diamond Grinding: The concrete floor is cut with a variety of diamond abrasive grits; usually 3-8 passes over the surface are required depending on the gloss level desired. (Many in the industry do not consider a 3 step grinding to be truly polished concrete since waxes are then used to achieve the gloss – which results in much higher maintenance).
  2. A densifier is applied once the concrete is opened up and in a condition to readily accept the chemical.
  3. Diamond Polishing: The densifier is allowed to dry and cure for the manufacturers recommended time, followed by one or more abrasive cuts, which will polish the floor to the desired gloss. American’s HTC brand polisher is remote controlled so we can get into tight spaces and outfitted with an edger tool for a more finished look
