What You'll Learn
Corroseal's unique chemical conversion process
Corroseal is a water-based rust converter that works by chemically converting rust into an inert substance, magnetite. This stabilizes the surface, creating a protective barrier that prevents further rust formation. The process involves the following steps:
Firstly, it is important to prepare the surface by removing any dirt, grease, oil, and loose rust particles. This can be done using sandpaper, steel wool, or abrasive blasting. The surface should be clean and free of any residue before applying Corroseal.
Once the surface is prepared, Corroseal can be applied liberally with a brush, roller, or sprayer. It is important to work the product into the rust and pores, ensuring full coverage. Corroseal should be applied in a well-ventilated outdoor area, and it is recommended to wear protective gear as the product contains mild acids that can irritate the skin and eyes.
After application, allow Corroseal to dry for at least 24 hours. The surface will turn from yellow to black as it cures, providing a clear indication of the treated areas. This black finish also serves as a sound foundation for topcoat painting if desired.
The unique chemical conversion process of Corroseal transforms the iron oxide into a stable, inert substance. This prevents the spread of corrosion and preserves the integrity of the metal. The converted rust finish provides good protection on its own, but Corroseal can also be painted over for enhanced weather resistance and aesthetics.
Corroseal's innovative formula not only converts rust but also primes the surface, providing a high-quality latex metal primer that improves paint adhesion. This two-in-one product reduces labour costs and time by eliminating the need for separate rust removal and surface preparation steps.

How to prepare surfaces for Corroseal
Corroseal is a water-based rust converter that transforms existing rust into an inert protective layer, preventing the spread of corrosion and preserving the integrity of the metal. It is non-flammable, non-corrosive, and easy to apply. It can be applied to most iron and steel surfaces, but it is not recommended for galvanized steel or other zinc surfaces.
To prepare surfaces for Corroseal, it is important to ensure that the surface is clean and free of any contaminants that may interfere with the product's effectiveness. Here are the steps to prepare a surface for Corroseal:
Clean the surface — Remove any loose rust, flaking paint, oil, grease, dirt, and other deposits. Use a wire brush, abrasive pad, scraper, or solvent to clean the surface thoroughly. For glossy paint, use 40-60 grit sandpaper to roughen the surface, which will help the Corroseal penetrate and adhere better.
Degrease oily surfaces — If the surface is oily, use a degreaser such as acetone to ensure that the area is free of any grease or oil that may interfere with the Corroseal's adhesion.
Mask off nearby surfaces — Use painter's tape and plastic sheeting to protect any nearby surfaces that should not come into contact with the Corroseal. This will help ensure that the Corroseal is applied only to the intended areas.
Apply a test patch — Before proceeding with a full application, it is recommended to test Corroseal on a small, inconspicuous area to ensure compatibility with the surface and to gauge the reaction time needed.
Shake the bottle — Corroseal separates during storage, so it is important to shake the bottle thoroughly before use to ensure that the product is mixed properly.
Apply Corroseal — Apply a uniform coat of Corroseal using a brush, roller, or sprayer. Work it into the rusted areas and pores of the surface. One coat is typically sufficient, but be sure to apply enough to effectively convert all the rust. Allow at least 24 hours of drying time before applying a finish coat.
By following these steps, you can effectively prepare surfaces for Corroseal, ensuring maximum product performance and protection against rust and corrosion.

Applying Corroseal to painter surfaces
Corroseal is a water-based rust converter that combines with an unpigmented high-quality copolymer latex metal primer. It is ideal for treating rusted metal surfaces, as it chemically converts rust (iron oxide) into a stable substance called magnetite, which is black and inert. This process not only stops the spread of corrosion but also primes the surface for painting.
Before applying Corroseal to painted surfaces, it is important to note that it is specifically designed for treating rusted metal surfaces. If the painted surface is not rusted, Corroseal will still adhere to it, but it will not provide any additional rust prevention. However, if the painted surface has rust spots, Corroseal can be applied effectively to treat the rust and prepare the surface for painting.
To apply Corroseal to a painted surface with rust, follow these steps:
- Prepare the surface: Use 40-60 grit sandpaper to roughen up smooth, glossy regions. This helps the Corroseal penetrate better. Remove any loose rust, flaking paint, oil, and grease from the surface using sandpaper, steel wool, or abrasive blasting. Ensure that the surface is clean and dry before proceeding.
- Protect nearby surfaces: Use masking tape and plastic sheeting to mask off nearby surfaces that you do not want to be treated with Corroseal.
- Mix and apply Corroseal: Shake the bottle thoroughly to mix the contents, as Corroseal separates during storage. Apply a uniform coat of Corroseal using a brush, roller, or sprayer. Work it into the rusted areas and pores of the painted surface. One coat is typically sufficient, but ensure you apply enough to effectively convert all the rust. Allow at least 24 hours of drying time before proceeding to the next step.
- Topcoat application (optional): For enhanced weather resistance and aesthetics, you can apply a finish coat or topcoat over the Corroseal. Ensure the Corroseal is completely dry before applying the topcoat. Remove any excess dust or dirt from the surface before painting for the best results. Scuff sanding can also be done for added adhesion.
By following these steps, you can effectively apply Corroseal to painted surfaces with rust, treating the rust and preparing the surface for further painting if desired.
