Sika Wintermix

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. Conforms to EN934-3 (2009).

Benefits

• Increased frost resistance during setting.
• Non - corrosive to imbedded metal (chloride ion free)
• 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.
• Chloride free (chloride ion content < 0.1%).
• 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.

Areas For Use

• As an air entraining water reducing admixture and accelerator/frostproofer for brick and block laying mortar, render (internal and external) and concrete. Accelerates setting time during cold periods. Suitable for:
• Load bearing brickwork
• Block laying
• External/Internal rendering
• Pointing/repointing brickwork.
• Floor screeds

Limitations

• Concrete must be covered after placing until the minimum strength is obtained or until the temperature rises above freezing.
• Do not use weak mixes during cold weather.
• Do not overdose.
