Surface Deactivator


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 with uncertain levels of retardation, Surface Deactivator selectively halts the hydration process down to a controlled depth.

Eleven predetermined depths of exposure are available, color-coded for identification, to provide consistent, repeatable cement paste removal and aggregate reveal. Because Surface Deactivator 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. Surface Deactivator is water-soluble for easy removal with high-pressure water washing and scrubbing equipment.

Surface Deactivator creates a polymeric flim that acts as a water retention barrier and temporary curing agent, protecting fresh concrete from light rain and reducing moisture loss.

Surface Deactivator can be applied to newly-placed concrete that is specified for diamond polishing. It softens surface cement paste, reducing heavy grinding stages up to 75%, dramatically decreasing polishing time as well as diamond-tooling and labor costs.
