What are the major benefits of a release agent for concrete molding?

Obviously enabling the easy removal of cured parts from different molded materials is an important reason for using a release agent. What many do not consider is that these same materials can greatly increase mold life by maintaining a lubricious film on the mold surface that will prevent the cured concrete from deteriorating the interface. These products can also aid in the wetting out of pigments and improve color transfer from the mold substrate to the stone. This can help to minimize scrap caused by color changes. All of these benefits result in a more efficient operation.
