Levels of Polished Concrete

Spacious modern entryway with polished concrete floors and high ceilings. A rustic wooden table with a white orchid centerpiece sits on a textured beige rug in front of large windows with black trim, offering a view of greenery outside. On the left, a large framed botanical artwork hangs on white shiplap walls. On the right, a wooden console table with black metal legs holds a potted fern and decorative items, with a large wooden panel mounted above it. A glass chandelier hangs from the ceiling.

In a previous article, we discussed the importance of aggregate choice when deciding to create a polished concrete surface. At the lightest level of concrete grinding, a cream surface or finish, the only question might be the type of sand you decide to use within the concrete. With a light grind, the larger aggregates remain below the surface. With the medium and deeper concrete grinds, however, that’s when the aggregates literally start to shine.

Medium Grind Polished Concrete

With a medium grind we get down to the level of the smaller stones and pebbles in the concrete. Some contractors and installers call this the “salt and pepper” finish. If a proper mix of aggregates was planned for the concrete, that name can even be literal, with the stones shifting from dark to light hues for a distinctive patterned effect. This type of concrete grind looks good when combined with a high-gloss finish coat.

Deep Grind Terrazzo Finish

Going deep beyond the surface of the finished concrete reveals the largest aggregates. If properly planned, this type of polished concrete looks much like the ancient terrazzo floors and mosaic surfaces of the Mediterranean world. While this technique obviously takes the most time and therefore has the highest cost, it also has the biggest payback in boldness and design impact. Designers and installers also call this rock-cut polished concrete.
