Get Your Opti-Mix Plasticiser From Greengates Builders Merchants Accrington, Lancashire

OPTI-MIX forms extremely stable air bubbles in mortar mixes. This improves the workability of mortar, giving it a “buttery” consistency and helps prevent shrinkage, cracking, crazing and mild frost damage during the curing process, as well as providing long term resistance to freeze/thaw cycles. OPTI-MIX 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.

OPTI-MIX MORTAR PLASTICISER is a highly concentrated air entraining liquid plasticising admixture which is 25 times the strength of conventional products.


Add Optimix to a bucket of water and stir/mix well (use up to a maximum 10ltrs of water). Dry mix all other ingredients and add sufficient quantities of water/Optimix solution until the desired consistency is achieved. Never add Optimix directly to the dry mix, always let down into a portion of gauging water. Replace cap after use.
