Sika Wintermix 5L
Sika Wintermix is 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.
Usage
- As an air entraining water reducing admixture and accelerator/frostproofer for brick and block laying mortar, render (internal and external) and concrete.
- Suitable for load bearing brickwork, block laying, external and internal rendering, pointing/repointing brickwork, floor screeds
Advantages
- 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.
Typical Reduction in Setting Times 20-30% at 2.5Ltr/50Kg cement
