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.
