HC-10 Surface retarder



Product to make the setting of the concrete surface slower and thus obtain decorative finishes such as exposed aggregate concrete. The finish will result in a rough surface in which the aggregates are visible. Therefore, depending on the waiting time and the amount of retarder used, the layer of retarded set concrete will be more or less thick.


Spray the HC-10 on the still fresh concrete. Leave to work for 6 to 10 hours, depending on the room temperature, then apply pressure water (100-20 Kg / cm2) to remove the surface part of the concrete
