Polished Concrete Professionals

Types of Polishing

The Professionals use the various polishing methods approved by the Concrete Polishing Association of America to provide the desired finished gloss. The type of polishing necessary may depend upon the current state of the concrete floor and the desired finish.

Bonded Abrasive Polished Concrete:

TTROSA_0756his method involves a multi-step operation to mechanically grind, hone and polish the concrete floor surface with bonded abrasives. The process requires bonded abrasives to cut the floor surface and refine each cut to its maximum potential until it reaches the desired gloss and aggregate exposure*.  Bonded Abrasive Polished Concrete has proven to offer the most durable finish and requires less maintenance than other methods.

Burnished Polished Concrete:

Hybrid Polished Concrete:

The hybrid approach uses a combination of the above methods employing a combination of polishing, lightweight, and high-speed burnishing equipment to achieve the desired finished gloss.

Finished Gloss – Processing a concrete floor surface to achieve a specified level of finished gloss prior to application of any protective treatment; Flat [ground], satin [honed], semi polished, and highly polished are measured in reflective clarity (DOI), and reflective sheen (specular gloss). Finished Gloss is classified as levels 1, 2, 3 and 4 with varying degrees of reflective clarity, and sheen. (see Finished Gloss Chart)

*Consistent aggregate exposure cannot be guaranteed on existing concrete floors. To achieve specific aggregate exposure, concrete must be poured to certain specifications and polished using the bonded abrasive method. See concrete recommendations for polished concrete at the CPAA website.
