Polymer admixture for use with concrete repair mortars

Description

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 6mm.

There are 2 mix designs when using Ronafix SBR as a concrete repair mortar. Ronafix SBR Mix Design A is used for concrete repairs where there is no exposed steel reinforcement and Ronafix SBR Mix Design D is used where any reinforcement is exposed.
