Epoxy and Polished Floors of Columbus offers concrete polishing services and the simpler and more cost-effective “Grind and Seal” method. Both Polished Concrete and Grind and Seal will show at least some “salt and pepper” look from the concrete and offer a natural look that many of our customers are looking for. There is a time and a place for both methods.
There is some confusion in the marketplace on what qualifies as polished concrete. When we are speaking about Polished Concrete Flooring, we are not referring to applying a surface polish or coating.
Concrete Floor Polishing is similar to polishing granite or marble—the surface itself is finely ground down with specialized equipment (diamond tooling). The glossiness that results reflects the elements of the concrete itself.
Not only does this process give the concrete a smooth surface (which can range from a dull luster to a high shine, depending on how intensely it’s polished), but it actually compresses the molecules of the concrete together. Polished concrete is at the densest, hardest state it can be in.
Polished Concrete is common in retail and grocery stores, restaurants, office buildings, and airports.
EPFC strives to ensure each of our polished floors meet or exceed industry standards recognized by the CPAA (Concrete Polishing Association of America).
- Gloss Level, also known as Specular Reflection
- The Distinction of Image (DOI) and Haze
- Abrasion Resistance
- Slip Coefficient of Friction (SCOF)
- Roughness Average (RA)
It helps to compare Concrete polishing to television resolution levels. Standard concrete would be an old knob controlled TV, while Polished Concrete offers various levels of high-end clarity. We offer everything from a low level of gloss and clarity up to an extra high resolution with amazing clarity. Each clarity level offers excellent durability.
Our concrete polishing process is done in stages. First is the grinding process that removes the soft top layer, commonly known as the “cream layer”. This is done with a rough grit diamond disc then slowly working up to finer grit discs. With each pass the smoother the surface becomes.
Advantages of Polished Concrete
Durability: Dense Polished Concrete reaches a hardness of 7 on the Mohs scale (mineral hardness). It is hard to scratch or damage, even with heavy equipment.
Aesthetics: Polished Concrete offers a popular, simple, and clean look for any facility. Dyes and patterns can be added to fit the facility’s decor.
Cleanliness: Untreated concrete sheds dust over time as it ages. Polished Concrete does not release this dust. Polished floors are easy to clean and maintain and improve air quality.
