*Aggregate size, shape and color will<br />
vary depending on specific concrete.<br />
Class A: Cream Aggregate: Polished surface resulting in little-to-no aggregate exposure. Some light<br />
sand exposure.<br />
Class B: Fine/Sand Aggregate: Removes not more than 1/16" of concrete surface by grinding and<br />
polishing resulting in majority of exposure displaying fine aggregate with little-to-no medium<br />
aggregate at random locations. Light exposure with some cream.<br />
Class C: Medium Aggregate: Removes not more than 1/8" of concrete surface by grinding and<br />
polishing resulting in the majority of exposure displaying medium aggregate with little-to-no large<br />
aggregate at random locations. Light sand exposure with some heavy aggregate.<br />
Class D: Large Aggregate: Removes not more than 1/4" of concrete surface by grinding and polishing<br />
resulting in the majority of exposure displaying large aggregate with little-to-no small amounts of fine<br />
aggregate at random locations. Heavy aggregate exposure with some light sand.
