Arc Frostproofer & Rapid Hardener 25L

The Arc Frostproofer & Rapid Hardener 25L is a high-performance, chloride-free liquid admixture designed to accelerate the setting and hardening of cement-based mixes while providing protection in cold weather conditions. Suitable for use in concrete, mortar, screeds, and renders, it improves early strength development and helps maintain workability in low temperatures. By increasing the rate of hydration, it reduces curing times and enhances frost resistance during the critical setting phase, making it ideal for year-round construction work. It can also improve density and water resistance of the finished mix, delivering a more durable result for demanding applications.
