This SikaMix Frostproofer & Plasticiser is an air-entraining and chloride-free liquid admixture for mortar and concrete. It is especially designed to act as an accelerator for work in sub-zero temperatures. This product eliminates the need for a separate frostproofer and greatly improves the workability and thaw resistance in brick laying mortars.

Key Features

• Suitable for use during rendering, load-bearing brickwork, pointing and repointing brickwork, block laying and for laying floor screeds
• Replaces lime in mixtures, which reduces the risk of lime bloom and efflorescence
• Improves workability and accelerates setting times, even in cold weather
• Provides freeze resistance down to -8°C in both wet and dry mortar
• Reduces bleeding and segregation in your mixes
• Makes tamping down and alignment easy
• Reduces shrinkage, cracking and crazing
• Increased frost resistance during setting
• Non-corrosive to embedded metal
