Ronafix SBR is a single part modified styrene butadiene liquid additive for cement mortars which enhances physical and chemical properties, allows mortars to be placed in thin section, provides waterproofing and resistance to frost and promotes adhesion to building surfaces.
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.
There are 2 mix designs when using Ronafix SBR as a waterproof render. Ronafix Mix Design A is used for weatherproofing and Ronafix Mix Design E is used for tanking.
Typical substrates for Ronafix SBR renders are brickwork, blockwork and concrete, following appropriate preparation.
