Everbuild SikaBond SBR+ is a one-component, water-based, general-purpose styrene butadiene rubber emulsion bonding agent and mortar admixture. It is designed for improving adhesion, workability, and waterproofing of mortars. This versatile product has numerous uses, including as an admixture for mortar, screeds, and renders, as a primer/sealer for tiling applications, and as a bonding agent for screeds and renders. SikaBond SBR+ can also be used to flexibilise cementitious-based tile adhesives when tiling on wooden or asphalt floors. Unlike PVA bonding aids, SikaBond SBR+ is not adversely affected by moisture.
