Concrete forms, even if they are ground, smoothed and polished, require a release agent to prevent sticking and enable easy stripping. Light colored petroleum oils or oil emulsions or various types have been used successfully.

Form release agents ease formwork removal, extending the useful life of a form and improving the smoothness and texture of concrete surfaces. Two main types are available: barrier and chemically active.
