SikaTard® R

Set retarding/stabilising admixture

SikaTard® R is a liquid admixture developed for the control of cement hydration. SikaTard® R retards/stabilises sand/cement masonry mortars and concrete mixes.

SikaTard® R retards/stabilises the hydration of the cement.
  • Strong retardation/stabilising to enable brick/block laying to continue over long periods of time
  • Delays the set of the mortar, however the retarding/stabilising effect declines once in place as moisture evaporates and migrates due to the suction of the brick/block enabling setting and curing to occur as normal
  • Provides higher ultimate strengths
