Harmony Accelerator Recommended
Harmony Accelerator

The Accelerator for Concrete is a chlorine-free additive specifically designed to speed up the setting time of concrete mixtures. It enables high mechanical strength in the short term through faster hardening. This additive reduces application time, making it ideal for projects requiring rapid drying, especially in cold weather conditions. In low temperatures, it also helps freshly poured concrete resist freezing.
