Product Description BPI Water-Resistant Plasticiser For Mortar & Render is a premium-grade, high-strength liquid admixture designed to improve the workability, plasticity, and durability of mortar mixes while significantly enhancing resistance to water penetration. Formulated for professional use, this air-entraining plasticiser reacts with free lime within the mortar to form hydrophobic crystals, helping to block capillaries and reduce water ingress. It provides all the benefits of a traditional mortar plasticiser while delivering improved performance in damp-prone environments. Conforming to EN 934-3:2009 A1:2012 (Type T2), it is ideal for both internal and external applications where reliable moisture resistance is essential. Special Features Improves mortar plasticity and workability for easier application Enhances resistance to water penetration Reduces suction in multi-layer renders Forms hydrophobic crystals to block pores within the mix Minimises cracking and crazing Reduces the need for lime in mortar mixes Simply added to gauging water Typical Applications Suitable for a wide range of construction and refurbishment applications, including: External and internal rendering Basement walls and below-ground structures Retaining walls Roof screeds Tanks and reservoirs Swimming pools Any application where water ingress is a concern Application & Dosage Shake well before use Add to gauging water before mixing Typical dosage: 0.25 – 0.5 litres per 25kg of cement Reduce gauging water accordingly to achieve desired consistency Ensure mortar is well compacted and avoid overmixing Specification Standard: EN 934-3:2009 A1:2012 – Type T2 Form: Liquid pH: 12–14 Chloride ion content: <0.1% Alkali content: <1.5% Density: ~1 g/cm³ Colour: Pink Health & Safety For all technical and safety data sheets please see the downloads section.
