Winter working admixture and frostproofer. 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. - Increased frost resistance during setting.
- Non - corrosive to embedded metal.
- Eases tamping down and alignment.
- Improves workability/trowelability even in cold weather.
- Provides resistance to freeze/thaw cycling down to -8 °C in both wet and dry mortar.
- Reduces bleeding/segregation.
- Replaces lime in mix, hence reduces possibility of lime bloom and efflorescence.
- Reduces shrinkage (cracking and crazing reduced).
- Faster finishing times even in cold weather.
