A surface passivator temporarily retards the hydration process on the top surface of freshly poured concrete, allowing the top paste to be washed off easily to expose the aggregate beneath for an aesthetically pleasing, slip-resistant finish.
Selection depends on the aggregate size: use 0.5 for No. 5 fine sand (0.5mm depth), 1.0 for glass sand or 1-3 aggregate (1mm depth), 2.0 for 3-5 gravel flooring (2mm depth), and 3.0 for exposed stone walls and floors (3mm depth).
Yes, our formula is designed for wide versatility and construction can proceed safely under both high- and low-temperature weather conditions without compromising retarding efficiency.
