A sealant is a substance used to block the passage of fluids through the surface or joints or openings in materials. Used on porous models
Release Agents are a topic unto themselves. Applying no release agent or the wrong release agent can result in your mold rubber bonding or mechanically locking on to your original model.
The type of release agent you choose to release mold rubber from a surface depends on the type of rubber you are using to make your mold and the surface you are releasing it from.

A release agent (also mold release agent, release coating, or mold release coating) is a chemical used to prevent other materials from bonding to surfaces. It can provide a solution in processes involving mold release.
Release agents provide the critical barrier between a molding surface and the substrate, facilitating separation of the cured part from the mold. Without such a barrier in place, the substrate would become fused to the mold surface, resulting in difficult clean-up and dramatic loss in production efficiency. Even when a release agent is used, factors such as irregular applications or improper release agent choice may have a dramatic effect on the quality and consistency of the finished product
