ARC Frostproofer and rapid hardener is a chloride-free, concentrated liquid admixture for concrete and mortar which rapidly accelerates the setting and hardening times of cement mixes. Arc Frostproofer and Rapid Hardener produces a more dense concrete which improves the oil and water resistance of the mix. When mixed neat with Portland Cement it can be used to plug holes caused by pressure leaks. The admixture will also increase the workability of the mix so a separate plasticiser is not required.

Key features:

• 5L
• Chloride-free
• Concentrated liquid admixture for concrete and mortar 
• Produces a more dense concrete which improves oil and water resistance of the mix
• Admixture will also increase the workability of the mix so a separate plasticiser is not required
