Help Choosing the Right Size

Turn rust on iron and steel into a stable black base for repainting. This water-based formula combines rust conversion and priming in one product.

Expect a black coating, not bare metal. If you want to remove rust and keep the original metal appearance, choose a rust-removal method suited to that goal. This coating does not fill holes or restore lost metal strength.

Start with sound iron or steel that has surface rust. Typical projects include fences, gates, railings, tools and machinery. The metal underneath must still be firm and intact.

Remove loose, flaking rust and old paint first so the treatment can reach the rusted surface. Rust-through, weakened joints or badly deteriorated parts need assessment and repair or replacement before coating.

For aluminum, galvanized metal, rust-free surfaces or a specialist application, check suitability with our team before buying.

Prepare: Use sandpaper to remove loose rust and old paint. Clean away oil, dirt and dust, then let the surface dry completely.

Stir & apply: Stir thoroughly. Brush or roll a thin, even coat over the prepared rusted area. The application guide recommends a second coat after about 1 hour; follow the instructions on your pack and allow for your project conditions.

Clean up: Clean tools with water immediately after use. Keep the container sealed in a cool, dry place.

Curing: The application guide gives 24–48 hours for full cure. Coat thickness, temperature, humidity and surface condition can change the time needed.

Planning a topcoat? This product forms a black priming layer. The cure time above is not a universal topcoat waiting time. Confirm that your chosen paint is compatible and follow the preparation and recoating directions for both products.

Send us your topcoat brand and product name, along with a photo of the project, to check the coating system and whether a topcoat is needed for the intended exposure.

Choose 16 oz or 32 oz for the area you need to treat. Account for every side of rails or frames, surface texture, rust condition and the number of coats; the size of an object alone does not tell you how much product it needs.
