Prime Exposure is a water based chemical retarder used to expose the aggregate in horizontal/vertical concrete surfaces. It delays the set of the mortar paste on the surface to a controlled depth. It does not kill the set of the main concrete. The paste may be removed by washing and brushing, after the set of the concrete, to expose the aggregate. After retardation has finished, the concrete cures to its full strength.
