Description
Surface Retarder – Plus Extra (RB7.17EX) is a concrete surface retarder recommended to be used on concrete with strengths of over 40 MPA. Ideal for use in the forming of construction joints in high strength concrete in both precast and civil construction. When applied to the surface of freshly poured concrete it delays the normal hydration of cement for a depth of 3-6mm (and occasionally deeper), whilst the underlaying concrete hardens normally.
