1. Polish GRADE – the aggregate (rock) exposure level: Depending on how heavily the surface is ground varying degrees of aggregate can be exposed, each level having it’s own design characteristics.
GRADE 1 (CREAM) – The most polular grade for commercial & industrial, requires the least amount of grinding & results in a creamy look by only exposing fine sand particles at the surface.
GRADE 2 (FINE/SALT & PEPPER) – concrete is ground 1/16″ exposing sand & fine rock particles resulting in a salt & pepper look.
GRADE 3 (MEDIUM) – concrete is ground 1/8″ exposing small to mid size aggregate.
GRADE 4 (LARGE) – concrete is ground 1/4″ exposing large aggregate, comparable to the look of terrazo.
