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, D-Activator selectively halts the hydration process down to a controlled depth
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
Water-soluble for easy removal with high pressure water washing scrubbing equipment
Coverage: 150 square feet per gallon
Size: 5 Gallon Pail
5 pre-determined depths of exposure are available, color-coded for identification to provide consistent, repeatable cement paste removal and aggregate reveal
