Surface Deactivator 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. Surface Deactivator 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, Surface Deactivator selectively halts the hydration process down to a controlled depth, allowing a more certain level of retardation. Ten predetermined color-coded exposure depths are available to provide consistent, repeatable cement paste removal and aggregate reveal. Surface Deactivator provides a longer window before the surface paste must be removed, allowing underlying concrete to harden properly, locking in aggregate, and reducing pop-outs. Surface Deactivator is water-soluble for easy removal with high pressure water washing and scrubbing equipment.
