What are barrier release agents designed to do?

Barrier release agents play a crucial role in the concrete setting process by creating a separation between the formwork and the concrete. This is essential because it allows for the easy removal of the form after the concrete has cured. If the form and the concrete stick together, it can damage both the form and the finished surface of the concrete. The release agents are typically applied to the inside of the forms to ensure that when the concrete is poured and subsequently hardens, it does not adhere to the mold. This ensures a smooth finish on the concrete while protecting the integrity of the form for future use.

While other options may deal with concrete in different ways—like decorative patterns, preventing corrosion, or altering weight—the primary function of barrier release agents is specifically centered around facilitating the release of concrete from its mold.
