Overview

Coo-Var Red Oxide Metal Primer is a versatile, general-purpose primer specifically formulated for use on ferrous metal surfaces such as iron and steel. With its strong anti-corrosive properties, this primer provides an effective barrier against rust, making it an ideal base coat for long-lasting protection and adhesion.

The matt finish ensures a smooth surface for overcoating, while its easy application by brush, roller, or airless spray makes it suitable for both professional and DIY projects. Perfect for workshops, structural steel, gates, and more Coo-Var Red Oxide Metal Primer is your go-to solution for preparing ferrous metals with confidence.

• Provides excellent corrosion resistance
• Ideal for iron and steel surfaces
• Easy application by brush, roller, or airless spray

Preparation

Proper preparation is essential to ensure maximum adhesion, durability, and corrosion resistance when using Coo-Var Red Oxide Metal Primer. Follow these steps for optimal results:

• All surfaces must be clean, dry, and free from grease, oil, dirt, and other contaminants before application.
• Use a suitable cleaner such as Coo-Var Degreaser to remove any oil or grease prior to surface treatment.
• Dust, rust, and mill scale must be removed completely from bare steel surfaces.
• Blast cleaning to SA 2½ standard is highly recommended for optimal surface preparation and adhesion.
• If blast cleaning is impractical, use mechanical cleaning (e.g., wire brushing, grinding, or power tools).
• Hand cleaning is not sufficient, as it cannot achieve the necessary level of surface cleanliness for long-term performance.
• If blast cleaning is done after assembly, pay special attention to: edges and corners, nuts and bolts, weld seams and joints.
• Welds should be ground smooth if required, and all slag, weld spatter, and sharp edges must be removed to ensure proper coating adhesion.

By following these preparation steps, you create the ideal foundation for Coo-Var Red Oxide Metal Primer, ensuring strong protection and long-lasting performance on ferrous metal surfaces.

Application

To ensure a smooth, effective, and long-lasting finish, follow these application guidelines carefully:

• Mix thoroughly before use to ensure even pigment and consistency.
• Ensure all surfaces have been properly prepared (see preparation guide).
• Apply only in conditions where the surface temperature is above the dew point to prevent condensation and contamination.
• In confined or enclosed spaces, ensure there is adequate ventilation throughout application and drying.
• Apply using brush, roller, or airless spray, following standard good painting practices.
• Aim for even, full coverage across the surface.
• Avoid over-application or excessive film build-up, especially in corners and weld seams.
• Once the primer is fully dry (typically touch dry in 2 hours, hard dry in 12 hours), overcoat with a suitable finishing coat for added protection and durability.

Tip: Always consult your chosen topcoat’s instructions for compatibility to ensure optimal results.
