Product Information
Full details
The Hammerite No.1 Rust Beater in Dark Brown is designed for metal surfaces heavily affected by rust. Its primary benefit is its ability to kill existing rust and prevent new rust from forming, acting as a primer and undercoat in one. A potential caveat is its solvent-based composition, requiring good ventilation and careful handling. This product offers a high-build finish, is corrosion-resistant, compatible with most topcoats, and suitable for both interior and exterior applications on various metal items.

FAQs
Can I apply Hammerite No.1 Rust Beater over existing paint?
This product is designed for direct application to rust or sound, prepared metal. It is not intended as a renovation coat over existing, intact paintwork. Always prepare the surface by removing loose rust and paint.
How many coats of Hammerite No.1 Rust Beater should I apply?
It is recommended to apply two coats for optimal protection and finish, allowing 6 hours between coats.
What is the drying time for Hammerite No.1 Rust Beater?
The drying time is approximately 2 hours. However, it is recoatable after 6 hours, and a topcoat can be applied after a minimum of 6 hours (24 hours recommended for best results).
Is this product suitable for very rusty surfaces?
Yes, its high-build formulation is specifically designed for heavily pitted areas of rust, providing a protective finish.
Can I use this product on galvanized metal or aluminum?
This product is primarily for ferrous metals (iron and steel). For non-ferrous metals like galvanized steel or aluminum, a specific primer designed for those surfaces would be more appropriate.
What HSE (Health and Safety Executive) precautions should I take?
Ensure good ventilation, keep away from heat and ignition sources, avoid contact with skin and eyes, and do not breathe vapours. Wear appropriate protective gloves and eye protection. Keep out of reach of children. Refer to the HSE note in the product specifications for full details.
How do I clean my brushes after use?
After use, remove as much paint as possible from brushes before cleaning them with Hammerite Brush Cleaner & Thinners or white spirit.
Troubleshooting
Product won't stir or apply smoothly
Ensure the product has been stored correctly and is within its shelf life. Stir thoroughly for several minutes, ensuring any settled pigment at the bottom of the can is fully incorporated. If too thick for application, thin slightly with Hammerite Brush Cleaner & Thinners as per instructions.
Poor adhesion or flaking after drying
The surface may not have been prepared adequately. Ensure all loose rust, grease, and contaminants were removed before application. Surface humidity could also be a factor; ensure the surface was completely dry. Ensure a compatible topcoat was used and applied after the recommended recoat time.
Bubbling or blistering during application
This can be caused by applying the product too thickly, especially in humid conditions or at low temperatures. Apply thinner, more even coats and ensure adequate drying time between coats. Avoid application in direct hot sunlight or when rain is imminent.
Uneven color or finish
Ensure the product was stirred thoroughly before and during application. Apply even coats, avoiding over-brushing or excessive thinning. Ensure all areas received the recommended number of coats.

Setup, Compatibility & Care Instructions
Surface Preparation: Before application, ensure the metal surface is free from loose rust, scale, and old paint. Wire brushing or using coarse abrasive paper is recommended. For bare steel, abrade with emery paper to create a key. If the surface is greasy, clean it with white spirit and rinse with clean water, allowing it to dry completely.
Application: The ideal application temperature is between 8°C and 25°C. Stir the paint thoroughly before use. For brush application, apply two coats, allowing at least 6 hours between coats. For roller application, apply two thick coats, thinning with Hammerite Brush Cleaner & Thinners (9 parts paint to 1 part thinner) if necessary, and apply edges first before using the roller. A compatible Hammerite topcoat or paint system should be applied after a minimum of 6 hours, with 24 hours recommended for optimal results.
Compatibility: This product is compatible with most topcoats, but it is always advisable to test compatibility on a small, inconspicuous area first.
Tool Cleaning: After use, remove excess paint from brushes and tools before cleaning them with Hammerite Brush Cleaner & Thinners or white spirit.
