Everbuild 201 Mortar Admix Plasticiser 25L

Everbuild® 201 Mortar Admix – 25 L

Air-entraining, liquid-plasticising admixture in a 25 L jerry can. Designed to create extremely stable air bubbles in mortar mixes, it improves workability, trowelability, and freeze/thaw resistance while reducing the need for lime and smoothing variation between batches.

Key benefits

• Creates uniform air bubbles that maintain volume after 1 hour and with extra mixing—loss under 3 %, change within 5 %.
• Enhances trowelability, alignment, and consistency across mortar mixes.
• Improves freeze/thaw durability of both wet and dry mortar down to –2 °C.
• Chloride-free (<0.1 %), reduces bleeding and eliminates lime bloom and efflorescence risk.
• Outperforms traditional Vinsol resin-based plasticisers.

Typical applications

• Bricklaying and load-bearing brick/block work.
• External and internal rendering.
• Pointing and repointing of brickwork.

Usage guidance

• Dosage: 150–250 ml per 50 kg cement, depending on the degree of plasticising or air-entrainment required.
• Example: 1 L added to 200 L of gauging water will cover approximately four 50 kg bags of cement mix.
• Reduce water accordingly when using this admixture.
• Avoid overdosing, though the formula tolerates up to double the maximum dosage.
