How to Do Exposed Aggregate Concrete - 3 Ways to Expose

One top-surface retarder product is Surface Deactivator by Brickform, which provides ten exposure depths, from a simulated light acid etch or sand blast finish up to full exposure of 1 ” aggregate. Surface Deactivator offers an extended window before the surface paste is removed, allowing the concrete to harden properly, which locks in the aggregate and decreases pop-outs

For more severe discoloration, try using a mild acid solution (1% to 3% muriatic acid) Start with a mild concentration, since muriatic acid will remove concrete as the concentration increases. Use just enough to remove the discoloration. To control the depth of acid penetration, flood the hardened surface with water first, and allow it to dry
