Sika WinterMix Admixture - 5L (Box of 4)

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
