Sika® Wintermix

Winter working admixture and frostproofer

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.
  • 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
