Ronafix SBR is a single part modified styrene butadiene liquid additive for cement mortars used to bond copings, paviours, linear drainage channels, brick slips, and other components to concrete surfaces. The cured mortar has high physical strength, is waterproof and frost proof.
Mortars containing Ronafix SBR are used for a wide range of applications where thin high strength high performance mortars are required. Typical minimum application depth is 10mm.. Water permeability of Ronafix Mix C is extremely low, providing excellent resistance to frost and preventing passage of water through the mortar. Typical compressive strength of Ronafix Mix C is ≥ 50N/mm2, flexural and tensile strengths are considerably better than unmodified mortar. The compressive modulus is similar to that of lower strength concrete, reducing stress on the parent concrete.
