Which of the following is NOT a method of applying form release?

Heating is not a method typically used for applying form release agents. Form release agents are substances applied to molds or forms to prevent concrete from sticking to them, thereby allowing for an easy demolding process.

Spraying, whipping, and dipping are all common techniques employed to apply these agents effectively. Spraying involves using a spray nozzle to coat the mold surface evenly with the release agent. Whipping often utilizes a cloth or brush technique to distribute the agent, ensuring coverage of the mold. Dipping entails immersing the mold into a container of the release agent, allowing for complete coverage in a quick and efficient manner.

Conversely, heating does not serve as a means for this application. While heat can influence certain chemical properties of materials, in the context of form release agents, heating does not provide an effective method for application. Thus, it is clear that heating is not a recognized method for applying form release.
