Polished Concrete

The multi-step operation of mechanically grinding, honing,and polishing a concrete floor surface with bonded abrasives to cut a concrete floor surface and to refine each cut to the maximum potential to achieve a specified level of finished gloss as defined by the CPAA. This yields the most durable finish and requires the least maintenance.
Levels of Polished Concrete (Gloss):

Level 1 (flat)
A level 1 ground polish usually can be obtained by stopping below the 100-grit resin bond. When you look directly down at the floor, it will appear somewhat hazy with little if any clarity or reflection.

Level 2 (satin)
A level 2 honed polish is obtained by stopping at the 400-grit resin bond, producing a low-sheen finish. When you look directly down at the finished floor and at a distance of roughly 100 feet, you can start to see a slight overhead reflection. This grit level produces a low-luster matte finish.

Level 3 (semi-polished)
A level 3 polish is achieved by going up to an 800-grit or higher diamond abrasive. The surface will have a much higher sheen than that of level 2 finish, and you'll start to see good light reflectivity. At a distance of 30 to 50 feet, the floor will clearly reflect side and overhead lighting.

Level 4 (highly polished)
This level of polish produces a high degree of shine, so that when standing directly over the surface, you can see your reflection with total clarity. Also, the floor appears to be wet when viewed from different vantage points. A level 4 polish is obtained by going up to a 3,000-grit resin-bond diamond or by burnishing the floor with a high-speed burnisher outfitted with specialty buffing pads.

Classes of Polished Concrete (Aggregate):

Class A
Class A aggregate exposure is a cream finish with very little surface cut depth. Will have light aggregate exposure.

Class B

Class B aggregate exposure is a fine aggregate salt and pepper finish. It has an approximate surface cut depth of 1/16". Will have fine aggregate exposure with little or no medium aggregate at random locations. 

Class C

Class C aggregate exposure is a medium aggregate finish. It has an approximate surface cut depth of 1/8". Will have medium aggregate exposure with little or no large aggregate exposure at random locations. 

Class D

Class D aggregate exposure is a large aggregate finish. It has an approximate surface cut depth of 1/4". Will have large aggregate exposure with little or no fine aggregate exposure.
