1. Prepare the Rust Metal for Paint

How to paint over a rust metal

Now follow these steps as stated below.

  • Start your work in a well-ventilated area with a protective mask.
  • Lay a plastic below to collect the rust and dirt for recycling.
  • Cover nearby items with a cloth to protect them from over spray. 
  • Now scrub rusted places with a wire brush.
  • Use sandpaper to clean it again.
  • Clean all surfaces thoroughly with lint-free rags (it is a microfiber cloth that picks up lint like a magnet). 
  • Then use detergent with water and let dry. 
  • Cover any other hardware or areas you do not want to paint.

Now the next step. That metal is ready to eat the primer and then the color.

2. Use the Primer First

Use the metal paint Primer First

A primer is designed to seal a surface and provide a smooth paint experience without eating a log of original paint. Always use a primer before using the original paint. That primer must be an anti-rust primer.

You can choose any primer color your want, but the white primer works the best and gives the original paint more visibility. And also, dry the primer paint for a few hours before putting in the original paint.

3. Choose an Anti Rust Paint

Choose paint that stated like anti-rust, rust inhibitor, and rust-resistant paint. The name can be anything, but the purpose must be the same. And choose an oil-based paint for your metal as oil paint provides a good finish, bond tightly to metal, and are less likely to fade away anytime soon. 

3. Start Painting The Metal

Putting the primer is easy. Just use a paintbrush and put it there. But painting takes more effort and carefulness. Shake your paint can and then spray in a steady back-and-forth motion, slightly overlapping each stroke. Apply two light coats after a few minutes difference.

And remember, your primer must be in dry condition, or else the paint will not work as expected.

4. Start the Re-coating

Now let the paint dry according to the manufacturer’s guide, and start the re-coating. As a thumb rule, you should leave it for 24 hours. If you re-coat too early, it may cause the metal surface wrinkles, dimples, or bubbles. That will reduce its life span. 

5. Protect the New Paint

After it, you are done. Now it’s your duty to protect the paint. To extend the life of your metallic thing, cover it up to keep the moisture away and re-paint after some time (maybe a few years). That is all.
