Opti-mix Mortar Plasticiser

Brand may vary. A highly concentrated air entraining liquid plasticising admixture which is 25 times the strength of conventional products. It forms extremely stable air bubbles in mortar mixes. This improves the workability of mortar which helps prevent shrinkage, cracking, crazing and mild frost damage during the curing process, as well as providing long term resistance to freeze/thaw cycles. It replaces lime in the mix and hence reduces the chance of efflorescence (salt formation) and smoothes out variations between separate batches of sand and cement.
