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.

Available in 5ltr

How to use Sika Wintermix

Surface Preparation

• All materials used must be free from ice and the temperature of the mix prior to placing not be less than 4°C.
• 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.

Application

• Work should be carried out in accordance with the methods outlined in the Code of Practice BS5628 Part 3 for protection and use of mortars at low temperatures and DOE Advisory Leaflet No. 8.
• In all cases, add to mix at an addition rate of 2.5 to 5 litres per 50kg cement depending on the degree of plasticising/acceleration required.
• Note: remember to reduce required quantity of water accordingly. Alternatively, add to mixing drum at same time as water.
