Data Sheets
Sika MaxMix® Concentrated Accelerator & Frostproofer is a chloride-free, air-entraining admixture designed to accelerate the setting and hardening of mortars and renders. Formulated for cold-weather construction, it provides frost protection at temperatures down to -4°C while eliminating the need for a separate frostproofing additive. The product improves workability, reduces water absorption and penetration, and is safe for use with embedded metal components such as brick ties and reinforcement. Its concentrated formula delivers economical performance, with 1 litre treating up to 100 kg of cement, and features an easy-to-use dosage system that helps minimise waste and spillages.
Key Points:
– Accelerates setting and hardening times for faster progress on site.
– Air-entraining formula improves workability and helps protect against frost in sub-zero temperatures.
– Reduces water absorption and penetration for enhanced durability.
– Chloride-free, concentrated formula with an easy-to-use dosage system; 1 litre treats up to 100 kg of cement.
Shelf Life – 12 months from date of manufacture in unopened containers
Storage Conditions – Store in original unopened containers between +5 °C and +25 °C. Do not store above +30 °C
