Bostik Cementone SBR Admixture White 5ltr

Bostik SBR is a modified styrene-butadiene copolymer latex designed to improve the performance of cement-based mixes. It functions as a bonding agent, primer, and waterproofing additive, significantly enhancing adhesion, flexibility, and resistance to water ingress. The formulation toughens and densifies mortars, screeds, and renders, improving their durability and resistance to abrasion and chemical attack. When incorporated correctly, it produces stronger, more water-resistant surfaces ideal for both internal and external applications. Widely used in waterproof rendering, flooring, tanking, bedding, and concrete repair, Bostik SBR provides a reliable method of upgrading the performance of traditional cementitious materials in demanding site conditions.
