Overview:

SikaMix Plus Mortar Admix Plasticiser 5 Litre is a high-performance, liquid admixture for cement mortars used in bricklaying, pointing, rendering and plastering. Designed to replace lime, it improves workability and cohesion for easier trowelling and more consistent mixes, while helping reduce bleeding and segregation.

SikaMix Plus also helps (minimise the risk of efflorescence) associated with lime use and significantly improves frost resistance, providing resistance to freeze-thaw cycling down to -2°C in both wet and dry mortar (as stated in the Technical Data Sheet). Supplied in a 5L tub for regular trade use and larger jobs.
