Winter working admixture and frostproofer.

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.

  • 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.
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 loadbearing brickwork, block laying, external and internal rendering, pointing/repointing brickwork, floor screeds.

Technical Information
Concrete Mix Design

The following are examples of modified mix designs.

1: 0.25 :3 cement : lime : sand. .

use 1 : 3 cement : sand : + Sika® Wintermix

1:1:6 cement : lime : sand

use 1 : 6 cement : sand + Sika® Wintermix

BRICKLAYING/POINTING: Use a mix design appropriate to brick strength (1 : 3 to 1 : 6).

INTERNAL RENDERS: 1 : 6 + Sika® Wintermix

EXTERNAL RENDERS: 1 : 3 + Sika® Wintermix
