Water-Based Acrylic Rust-Preventing Primer

The Flash Harry Rust Stop Black 5L is a water-based acrylic primer formulated to provide long-term corrosion protection on properly prepared iron and steel surfaces.

Unlike rust converters, Rust Stop is designed to prevent rust rather than chemically convert existing corrosion. This makes thorough surface preparation essential before applying the product.

Its water-based formulation allows for convenient application and easy cleaning of tools while the coating is still wet.

Ideal Applications

Flash Harry Rust Stop Black is suitable for various metal protection and maintenance projects, including:

• Steel gates and fencing

• Metal handrails and balustrades

• Steel window and door frames

• Iron and steel roofing

• Structural steelwork

• Metal framework and supports

• Residential metal maintenance

• Industrial metal refurbishment

• General building and renovation projects

The surface must be compatible with the primer, and any additional finishing coats should be selected according to the manufacturer’s recommendations.

Rust Protection for Steel Gates and Fencing

Steel gates and fencing are regularly exposed to moisture, sunlight and changing weather conditions.

The Flash Harry Black Rust Stop Primer helps create a protective barrier over properly prepared metal surfaces, reducing the risk of corrosion developing beneath a suitable coating system.

Its black colour makes it particularly useful where a dark primer is preferred for metalwork.

For outdoor applications, applying a compatible finishing coat can provide additional protection and help achieve the desired decorative appearance.

Suitable for Metal Roofing and Steel Structures

Metal roofing and structural steel components can become vulnerable to rust when protective coatings deteriorate.

Flash Harry Rust Stop is designed to help protect compatible steel surfaces against corrosion.

It can be used as part of a suitable maintenance system for metal roofing, structural supports and other steel components.

For new untreated galvanised iron, the surface requires appropriate preparation with an acid-degreasing primer or compatible treatment before Rust Stop is applied.

Surface Preparation and Application

Correct surface preparation is essential for effective rust prevention.

Before applying Flash Harry Rust Stop Black 5L, ensure that the metal surface is clean, dry and free from grease, dirt, loose paint and rust.

For best results:

• Remove loose rust using a wire brush or suitable preparation equipment.

• Prepare rusted steel to a clean, bright metal finish.

• Remove dust, grease and surface contaminants.

• Stir the primer thoroughly before application.

• Apply using a suitable brush, roller or spray equipment.

• Apply two coats for the recommended protective system.

• Allow approximately 2–3 hours between coats under suitable conditions.

• Avoid application when rain is imminent.

The manufacturer recommends avoiding application at temperatures below 10°C or above 40°C.

Coverage and Quantity Planning

The Flash Harry Rust Stop Black 5L offers an approximate coverage rate of 7–8m² per litre per coat, depending on the surface condition and application method.

For a 5-litre container, estimated coverage is:

• One coat: Approximately 35–40m²

• Two coats: Approximately 17.5–20m²

Actual coverage may vary depending on surface texture, preparation, application thickness and wastage.

Drying and Overcoating

Flash Harry Rust Stop is designed for convenient application with suitable drying intervals.

At approximately 25°C, the manufacturer’s guidance indicates a minimum overcoating time of four hours for compatible water-based coatings and 48 hours for compatible solvent-based coatings.

Drying times can vary according to temperature, humidity and film thickness.

Always ensure the primer has dried sufficiently before applying additional coatings.

• Building contractors

Cleaning and Maintenance

Proper maintenance helps preserve the performance of a protective metal coating system.

Inspect treated surfaces periodically for scratches, peeling or exposed metal.

Repair damaged areas promptly to prevent moisture from reaching the underlying steel.

Clean brushes, rollers and application equipment with water while the primer is still wet.

Store unused product in a securely closed container according to the manufacturer’s recommendations.
