Description
Sika® Wintermix is an air entraining chloride free liquid admixture for mortar and concrete which also acts as an accelerator for work in sub - zero temperatures. Improves workability and freeze/thaw resistance in brick laying mortars and eliminates the need for a separate frostproofer.
Key Features
- Increased frost resistance during setting
- Non - corrosive to embedded metal
- Eases tamping down and alignment
- Reduces bleeding/segregation
- Reduces shrinkage (cracking and crazing reduced)
- Faster finishing times even in cold weather
- Improves workability/trowelability even in cold weather
- Provides resistance to freeze/thaw cycling down to 8 °C in both wet and dry mortar
- Replaces lime in mix, hence reduces possibility of lime bloom and efflorescence
