Scope of use

Avista Surface Retarder is used to reveal aggregate in freshly placed horizontal concrete by delaying the surface set so that the mortar paste may be washed from between the aggregate particles, after the mass of the concrete has set. This produces an attractive exposed aggregate finish, or a key for subsequent pours or renders eg. floors, driveways and paving.
