Form Oil

Definition

Form oil is oil applied to the interior surface of formwork to promote easy release from the concrete when forms are removed.

Purpose

The purpose of form oil is to prevent concrete from sticking to the formwork, ensuring a smooth finish and facilitating the removal of forms without damaging the concrete surface.

Examples of Use

• In concrete casting, form oil is applied to wooden or metal forms before pouring the concrete to ensure clean and easy removal once the concrete has set.
• Precast concrete manufacturing often uses form oil to maintain the integrity of molds and ensure high-quality surface finishes on concrete products.

Related Terms

• Form Release Agent: A substance applied to formwork to prevent concrete from adhering, similar to form oil.
• Concrete Mold: A form or mold used to shape concrete while it sets and hardens.
• Curing Compound: A substance applied to concrete to retain moisture during the curing process, distinct from form oil but often used in conjunction.

Notes

Using the right type and amount of form oil is crucial to achieving the desired results. Overuse or improper application can affect the concrete surface and adhesion of subsequent finishes.
