MasterFinish 380 is a water based chemical retarder used to expose the aggregate in horizontal concrete surfaces. MasterFinish 380 delays the set of the mortar paste on the surface to a controlled depth. MasterFinish 380 does not kill the set of the main concrete. The retarded mortar paste may be removed by washing and brushing after the set of the concrete to expose the aggregate.
