Description
CHRYSO® Tard CXR is a Non-Staining retarder for Exposing Aggregate from Concrete. This retards the concrete surface to a depth of approx.4 to6mm when a thin layer is applied on newly placed concrete.
Domains of application
Preferably sprayed on the newly laid concrete surface after the surface water evaporated in the big surface area like raft concrete.
The treated surface with CHRYSO® Tard CXR should be washed with jet water after the bottom concrete get set / attend initial setting to expose the aggregate for subsequent fresh concreting / other treatments for aesthetic look.

- § Will retards the concrete surface to a depth of approx. 5mm.
- § Will not affect the strength of structural concrete.
- § Will not have detrimental effect on reinforcement steel.
- § The retarded mortar is easily washed away with jet water.
- § The exposed surface is not stained.
- § It is very useful for mass concreting to avoid cold joints.
