Concrete Surface Retarder
Select-Etch by Brickform is a concrete surface retarder that makes exposed aggregate finishes easier and more consistent. It is topically applied to freshly-placed concrete to prevent cement paste hardening and achieve more controlled exposed aggregate finishes. Unlike sugar-based retarders with uncertain levels of retardation, Select-Etch selectively slows the hydration process down to a controlled depth. Twelve predetermined depths of exposure are available, color-coded for identification, to provide consistent, repeatable cement paste removal and aggregate reveal. Because Select-Etch provides a longer window before the surface paste must be removed, it allows underlying concrete to harden properly, locking in aggregate and reducing pop-outs. Select-Etch is water-soluble for easy removal with high-pressure water washing and scrubbing equipment. Select-Etch creates a polymeric film that acts as a water retention barrier and temporary curing agent, protecting fresh concrete from light rain and reducing moisture loss.
