Surface Retarder Material:R20 5 Gallon • Approved for use overR20 HORIZONTAL SURFACE RETARDER is a water Based liquid that when sprayed on fresh soft concrete will retard the cement and expose the aggregate to produce a three dimensional surface and will retard the set of the surface cement between 12 to 24 hours after application when applied as directed. The amount of retardation will be influenced by the concrete setting time which, in turn, is influenced by air temperature, mix design, slump, wind, concrete
