Marvell Mould Release Oil 4 – Premium Concrete Form Release Agent (205 L)

Product Overview

Marvell Mould Release Oil 4 is a high-performance, oil-based concrete form release agent formulated for use in demanding civil and construction environments. It contains a balanced blend of refined mineral oils and specialised release additives designed to ensure clean, effortless separation between formwork and freshly cast concrete. This product is particularly effective on plywood, hardwood and steel shuttering systems, delivering a smooth, stain-free surface finish with minimal blowholes and improved concrete texture.

Unlike water-based emulsions, Marvell Mould Release Oil 4 provides a uniform, water-repellent film that resists moisture absorption and maintains its performance under a wide range of environmental conditions. It is an excellent choice for builders, contractors and precast manufacturers seeking reliable performance, clean moulds and longer service life of formwork.

Specifications & Approvals

Marvell Mould Release Oil 4 meets and exceeds the general performance requirements of concrete release fluids commonly specified by Australian and international standards for oil-based form release agents.

Specifications & Performance Features

• Suitable for use on all common formwork surfaces including steel, aluminium, plywood, timber and plastic forms

• Compatible with both reinforced and plain concrete structures

• Free from silicone and harmful reactive chemicals that may affect subsequent surface coatings or finishes

• Provides a smooth, blemish-free concrete surface with reduced surface dusting and porosity

• Complies with the requirements for form oils used in civil engineering, bridge and precast concrete works

• Exhibits strong film integrity and excellent release performance over multiple pours when properly maintained

• Offers protection against corrosion on metal formwork during storage

Key Features & Benefits

1. Superior Release Performance
Forms a consistent, durable barrier film that prevents concrete adhesion, allowing for easy demoulding without surface tearing, drag marks or sticking.

2. Excellent Surface Finish
Produces smooth, uniform concrete surfaces free of patchiness, stains or voids, improving both appearance and structural consistency.

3. Extended Formwork Life
Reduces mechanical wear and tear on steel and timber formwork by minimising concrete build-up and the need for aggressive cleaning between pours.

4. Moisture Resistance & Protection
Provides a protective, hydrophobic layer on shuttering materials, reducing moisture penetration and preventing swelling or warping of timber formwork.

5. Wide Material Compatibility
Safe for use with a broad range of materials including plywood, MDF, steel, plastic, fibreglass and aluminium moulds. Does not cause corrosion or staining.

6. Non-Staining and Clean-Release Formula
Leaves no oily residues or patches on the concrete surface, making it suitable for architectural and structural concrete elements that require aesthetic precision.

7. Ease of Application
Can be easily applied by spray, brush or roller, ensuring even coverage and minimal wastage. Its low-viscosity design supports efficient use in both field and factory conditions.

8. Enhanced Productivity
Reduces downtime between casting cycles by facilitating quick release and cleaning, supporting higher productivity in precast and formwork operations.

9. Protection for Steel and Metal Forms
Contains anti-corrosive additives that protect metal formwork during both operation and storage, extending asset life and lowering replacement costs.

Applications

Marvell Mould Release Oil 4 is ideal for use across a wide range of concrete casting environments:

• Building and civil construction projects involving poured concrete columns, slabs, walls and beams

• Precast and tilt-panel manufacturing facilities where a high-quality surface finish is required

• Formwork systems made from timber, plywood, steel, aluminium or composite materials

• Infrastructure projects such as bridges, culverts and retaining walls

• Decorative and architectural concrete moulds demanding clean and consistent release performance

The oil provides excellent release characteristics even in humid or rainy conditions, maintaining consistent results across multiple reuses of the same formwork.

Handling & Storage Advice

• Store in tightly sealed original containers in a cool, dry and well-ventilated location away from direct sunlight and ignition sources.

• Avoid contact with strong oxidising agents or reactive chemicals.

• Use clean, dedicated spray or brush equipment to prevent contamination by other lubricants or chemicals.

• Do not dilute or mix with water or other form oils.

• Ensure all form surfaces are clean, dry and free of old oil or debris prior to application.

• Apply a thin, uniform coat and allow the film to settle before pouring concrete.

• Excessive application may result in dusting or minor surface variations.

• Dispose of used oil, empty containers and oily rags in accordance with local waste management regulations.

• Consult the Safety Data Sheet (SDS) for full health, safety and environmental information.

Directions for Use

1. Preparation: Clean the formwork thoroughly to remove old concrete residues, rust or contaminants.

2. Application: Apply Marvell Mould Release Oil 4 evenly using a low-pressure spray, brush or roller. Avoid over-application.

3. Curing: Allow sufficient time for the oil film to spread and bond to the form before concrete placement.

4. Re-use: After each use, remove residual concrete dust, inspect the surface, and reapply a light coat as required.

5. Storage of Forms: Before storing steel or timber forms, apply a thin film to prevent corrosion or moisture damage.

Advantages for Builders and Contractors

• Reduces form stripping time and effort, improving jobsite efficiency

• Enhances the surface quality of finished concrete products

• Extends the usable life of formwork and reduces replacement costs

• Provides consistent release even after repeated casting cycles

• Minimises cleaning downtime between pours

• Environmentally considerate formulation free from silicone and harmful reactive additives
