Sika MaxMix® Concentrated Mortar Plasticiser

No. Sika® MaxMix® Concentrated Mortar Plasticiser is not suitable for structural concrete, lime-based mortars, or mixes containing other additives in the same gauging water. It’s specifically formulated for sand/cement mortars.

One 1 L dosing bottle replaces 25 L of standard plasticiser, saving space, weight, and transport costs.

Recommended dosage is 5–10 mL per 50 kg of cement. Always dilute into gauging water before adding to the mix. Never add directly to the dry materials.

Sika® MaxMix® Concentrated Mortar Plasticiser introduces
stable microscopic air bubbles and reduces the water demand, giving mortar a creamy, smooth “buttery” consistency that trowels easily and holds well on the brick or block.

When used correctly, it improves handling and reduces water content without compromising the integrity of the mortar. It also helps reduce shrinkage and improves overall durability.

It’s an air-entraining plasticising admixture designed to improve the workability of sand/cement mixes such as bricklaying mortars, renders, pointing and screeds.

Yes, provided the dosage and usage instructions are followed. It contains less than 0.1 % chloride and is supported with a full Safety Data Sheet (SDS) for best practice handling.

Unlike household detergents, Sika® MaxMix® Concentrated Mortar Plasticiser is formulated and tested to BS EN 934-3, giving consistent, safe results without the risk of over-foaming or long-term durability issues.

Shake the bottle, measure the correct dose, dilute in part of the gauging water, and then add to the dry mix. Never add directly to dry cement or aggregates.
