Concentrated Admixtures Plasticiser

Opti-Mix® Mortar Plasticiser is a highly concentrated air entraining liquid plasticising admixture which is 25 times the strength of conventional products.

Opti-Mix® Mortar Plasticiser 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® Mortar Plasticiser 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 used for the following applications:

  • Pointing Mortars
  • Renders
  • Screeds
  • Bricklaying Mortars

Opti-Mix® Mortar Plasticiser has been tested to BS EN 934-Part 3.
