How to Expose Aggregate in Concrete
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 ½" 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.
