Rust Converter FAQ

Rust Converter FAQ


  1. How do I apply One Step Rust Converter? You may brush, roll, sponge, or use an airless sprayer to apply One Step on The rusted area.
  2. Can I use a sprayer? Yes, an airless sprayer is preferred for best results if you want to use a sprayer. Otherwise you can brush, sponge, or roll on.
  3. Can I put One-Step on hot engine parts or inside a tank? No. Do not apply One-Step Rust Converter to hot engine parts or any moving parts like an adjustable wrench. Also, never put One-Step inside of a tank with liquid without contacting our office first to go over your application.
  4. Can One-Step freeze? If one-step freezes and it is not a deep freeze then it can be thawed out.
  5. Do I need to use a top coat? No you do not. One Step Rust Converter is a one-step rust neutralizing primer. A user does not need to use a top coat after applying One-Step the Rust Killer for most applications. One-Step Rust Converter provides rust protection by itself without a top coat. You may choose to topcoat or not depending on the environment. One Step can also be sanded and/or puttied if desired. If considering a top coat for added rust protection, please view our top coat recommendation sheet.
  6. Do I need to sandblast or wire brush? You should remove what is loose and flaking and then you can leave the tightly adhered rust where it is. Then apply the One-Step the Rust Killer over the rust for long lasting results.
  7. Is One-Step safe to use? One-Step is water based and safer to use than most latex paints. For further information, please view the SDS sheet.
  8. How does it work? When One-step makes contact with rust it causes a chemical reaction that converts the rust into an inert polymer coating. In laymen terms it is a primer.
  9. How long will it last? It should not rust again at all. When used properly, any rust that may form would be new rust. One-step neutralizes and kills existing rust completely.
  10. What happens if I put it on non-rusted areas? It dries clear and has no negative effect.
  11. What color will it dry to? The final color depends on what stage of rust it is and the environment it is in. Generally it dries to a shade of black, but there are times where it just dries clear and is still killing the rust. When rust is very light, it may dry to a more brownish color because One-step turns black when neutralizing rust. This also applies for when you apply the product to a galvanized area.
  12. What is the surface preparation? Remove any loose flaking rust and leave the tightly adhered rust where it is. Clean with a suitable degreaser and then let it dry. You may then apply the One-Step Rust Converter and paint over the rust to kill, neutralize, and convert it.
