Description

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.

Uses

• 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

Benefits

• 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.
