Everbuild 203 Accelerator & Frostproofer 5L is a chloride-free liquid admixture designed to accelerate the setting and hardening of cement-based materials—including mortar, concrete, screeds, and render—while providing frost protection during cold weather. Effective down to –8°C, it’s ideal for winter construction and emergency repairs. It can also be used neat with cement as a plugging aid. The non-corrosive formula is safe for use with embedded metal and optimises mould usage for faster turnaround.

Recommended dosage:
• 2.5L per 50kg cement for protection down to –4°C
• 5L per 50kg cement for protection down to –8°C
• Add to gauging water and reduce total water accordingly
