Oil Based Concrete Form Release Agent G-FR Howto Videos

Oil Based Form Release for Concrete G-FR

G-FR is a professional-grade, oil-based concrete form release agent designed to prevent fresh concrete from bonding to molds or formwork surfaces. It is applied directly to wood, metal, plastic, rubber, and composite forms to allow for clean, easy separation once the concrete has cured. This ready-to-use, non-staining formula is ideal for both commercial construction and decorative concrete applications.

Whether you’re pouring slabs with standard plywood forms or casting detailed surfaces using architectural liners, G-FR helps produce smooth, bughole-free concrete finishes while significantly extending form life. It is fully VOC compliant and optimized for both indoor and outdoor use.

Coverage Rates (Approximate)

Form Surface Type	Coverage per Gallon
Steel, Plastic, Rubber, Aluminum	~ 1,600 sq. ft.
Pre-Treated Wood	~ 1,100 sq. ft.
Untreated (Raw) Wood	~ 800 sq. ft.

Actual coverage will vary depending on application method, surface porosity, and spray equipment.

Substrate Preparation

Ensure all form surfaces are clean, dry, and free of dirt, dust, rust, buildup, or previous release residue.
For architectural-grade finishes, remove even fine dust or fibers, as they may transfer to the concrete surface.
Suitable for use on:

Untreated or coated plywood
Steel or aluminum forms
ABS, PVC, fiberglass, and composite plastic forms
Elastomeric or urethane rubber liners (not for use with polystyrene or natural latex)

Application Instructions

Do not dilute. G-FR is ready to use directly from the container.
Use a solvent-resistant pump sprayer with a flat fan spray tip (e.g., 8001 or finer).
Spray a thin, even film across the form surface from a distance of 12–18 inches.
Avoid puddling or over-application. A thin coat provides the most effective release and finish.
For architectural concrete, wipe off excess from textured forms using a soft cloth dampened with product.
Apply 20 minutes to 14 days before pouring. Treated forms should be protected from dust and debris before use.

Clean-Up & Storage

Clean tools and spray equipment with mineral spirits or appropriate solvent after use.
Store in a tightly sealed original container, indoors or under cover, between -20°F and 140°F (-30°C to 60°C).
G-FR is classified as a Class 3B combustible liquid and meets OSHA storage exemptions for non-hazardous quantities under 55 gallons.

Frequently Asked Questions

Q: When should I apply form oil before pouring concrete?

A: G-FR Oil Based Form Release can be applied anywhere from 20 minutes up to 14 days before pouring concrete, as long as the treated forms are protected from dust, rain, or debris.

Q: What is form oil used for in concrete work?

A: G-FR is a form oil that creates a barrier between formwork and concrete, preventing sticking, reducing bugholes, and ensuring smooth form removal without damaging the surface.

Q: What surfaces can form release agent be used on?

A: G-FR works on a wide range of surfaces including wood (raw or treated), steel, aluminum, plastic, fiberglass, PVC, ABS, and rubber form liners. It should not be used on polystyrene or natural latex.

Q: Can I use concrete form release on decorative molds or liners?

A: Yes. G-FR is safe for use with decorative concrete form liners and rubber molds, delivering clean release without staining or detail loss, even on textured or custom surfaces.

Q: Will form oil affect paint, stain, or sealer applied after the concrete cures?

A: When applied correctly, G-FR does not interfere with adhesion of caulks, paints, sealers, or coatings on cured concrete surfaces.

Q: Is form oil VOC compliant and safe for indoor use?

A: G-FR is fully VOC compliant (240 g/L) and meets regulations including California Rule 1113. It is suitable for indoor and outdoor concrete formwork, provided there is adequate ventilation.

Q: How much coverage does concrete form release agent provide per gallon?

A: G-FR provides excellent coverage:

Up to 1,600 sq. ft. on smooth metal or plastic forms
Up to 1,100 sq. ft. on pre-oiled plywood
Up to 800 sq. ft. on raw, untreated wood forms

Q: Does form release need to be diluted before spraying?

A: No. G-FR is a ready-to-use oil-based form release — no dilution required. Simply pour it into a solvent-rated sprayer with a flat fan spray tip and apply a thin, even film.

Q: How do I clean equipment after using form oil?

A: After applying G-FR, clean all tools and sprayers with mineral spirits or a compatible solvent. Always store unused product in a tightly sealed container.

Q: Can I use used motor oil as concrete form release?

A: While some people use used motor oil as a makeshift release, it’s unsafe, environmentally harmful, and may stain the concrete. G-FR is a purpose-made, non-staining, VOC-compliant form release agent that performs consistently and meets jobsite safety standards.

Q: Can I use diesel or kerosene as a form oil substitute?

A: No. Diesel and kerosene are flammable, toxic, and often illegal to use as form oils, especially in regulated areas. G-FR offers a much safer alternative with professional results — without the health or environmental risks.

Q: Is cooking spray a good concrete form release?

A: Cooking spray might release concrete from small molds in a pinch, but it’s unreliable, inconsistent, and prone to leaving residue or stains. G-FR is designed specifically for concrete and works on everything from small molds to large structural formwork.

Q: Can I make homemade concrete form release oil?

A: DIY mixtures like diesel and oil can damage concrete finishes, violate VOC laws, and reduce form lifespan. G-FR is a professionally formulated concrete form oil that provides a clean release, preserves form integrity, and complies with environmental regulations.
