![]() You will also need to degrease and clean the surface with a detergent wash. Be careful not to remove all the rust as this is what needs to be converted and sealed in. You can prepare the surface with a wire brush, sandpaper, or scraper. The first step in applying a rust converter is to remove loose and flaky rust from the metal surface. Here’s how to apply rust converter on a rusted surface: Prepare the Surface of the Metal In this instance, the rust converter must not be prepared too thin as you run the risk of having it drip off the surface of your metal. ![]() Others are water-based and will require use in the form of a solution. Most rust converters come in liquid form and can be applied by either spraying or brushing. How to Apply Rust Converter to Rusted Metal If you must use it inside your tank, consider it only as a primer and paint over it with a paint that is resistant to what is stored in the tank. It is not recommended to apply rust converters inside a tank. Applying rust converter on a clean, non-rusty surface can also cause it to flash rust. This means that you can’t use it on bare metal or non-rusty surfaces. Also, rust converters are not heat resistant, so you can’t use them on your wood stove, grill, engine boiler, or other surfaces that will be heated.Īlso, for rust converters to work effectively, rust must be present on the metal surface. However, you should not use it on copper, stainless steel, aluminum, or galvanized steel because it won’t bond effectively. Typically, it works on any iron or steel surface that has rusted. Rust converter can be used on most metallic surfaces, including vehicles, tractors, machinery, tank exterior, fences and gates, tractor, lawn equipment, metal roofs, iron railings and staircases, mower decks, and metal furniture. Other additives used by rust converter manufacturers are solvents and wetting agents. An example of such acid is phosphoric acid, which converts the rust to inert, black iron phosphate. As the process develops, the rusted area turns to black as the rust converter becomes dry.Īpart from these two ingredients, manufacturers also add other acids to accelerate the chemical reaction. When the rust converter comes in contact with rust, it reacts with it and forms a blue film. When rust converter is applied to a rusted surface, the tannic acid reacts with the rust and converts it into a more stable iron tannate.Ī rust converter also contains an organic polymer that acts as a moisture barrier and provides a protective layer on the surface of the metal. Typically, rust converters contain tannic acid and an organic polymer. Surfaces coated with rust converters are also protected from elements such as rain, sun, carbon dioxide, and effects of weathering. The coating formed after the rust converter is applied to help seal out moisture and prevent rust from spreading or forming again. It is particularly relevant when used on large rust surfaces where traditional methods are time-consuming and expensive. This eliminates the need for sandblasting or scraping down rust from metal surfaces. Rust converters are chemical solutions that react with rust on metal surfaces to convert it into an inert, insoluble, black protective coating.
