How do I make aluminium roof sheets look old and rusty?

by Michele
I would like to give my new roof sheets - an old rusty look. What quick way is there of doing this.
I'm sure on Hometalk, I saw that I could use Hydrogen Peroxide ...

      Pour vinegar over it, Do it a few days in a row. It will start rusting out.

      Know Because I had a tenant put vinegar on the top of the disposal ( he wanted a new one) in a few weeks she burned a hole in it

    I'd try bleach. Unfinished metal will rust when exposed to bleach. Maybe a spray bottle?

    if they are aluminum you can't get them to rust. They will oxidize, but not rust. The best thing I have found to age aluminum, is bleach, which has already been suggested. If you want them to look rusty you will need to experiment with light sprays of brown, red primer, and yellow paint and dry brush to blend. If they are galvanized then lightly spraying them with muriatic acid or toilet bowl cleaner) will give them a patina. Make sure to do this outside, stay upwind, and wear goggles and gloves. Rinse well with water. After they are dry the patina can be enhanced (darkened) by wiping with gun blueing.

    oven cleaner always changes the finish. the longer it is on the more it oxidizes. dow oven cleaner

    You could have just bought old second hand ones!!!

    If you can get clear enamel paint and crumble rusty metal in it (or something resembling rust/oxidation)

    Then paint patches of this on the sheets

    Soak them in salt water

      I've seen on here how to oxidize/rust other types of metal like copper. Perhaps it will work for this application. It's simply table salt & vinegar. Rinse well after leaving it on overnight. Seal if you don't want the process to continue rusting.

    Aluminum sheets do not rust. Your pictures show corrugated sheet metal. If you're using it on a roof, you may get in trouble with leaking if you try to rust it prematurely. That said, a friend of mine used the corrugated metal as wainscoting in her country kitchen. She used muriatic acid to rust the areas she wanted.

    Sand the area that you want rusted and wipe clean with a damp cloth.Then cover the galvanized metal with Lysol Toilet Bowl Cleaner that contains bleach. when you have the areas covered place in a safe place outside (out of the reach of children & pets) and leave it exposed to the elements for at least 4 hrs or overnight. When times up, rinse the solution off with water and allow to dry. Hopefully, your metal will be rusted and have an aged appearance! I got these directions from a post done by The Graphic Fairy. I hope it works!

    Try vinegar, it removes galvanized coating, and it's a lot safer than oven cleaner and better for the environment than a number of the suggestions. If you try using Muriatic acid, it might work but DO NOT breathe those fumes, they are very caustic to lungs!

    If they are really aluminum they won't rust

    Are your panels actually tin, rather than aluminum? If so, there are many methods to create rust, some quicker than others! :-)

    Hi Michelle! I previously suggested the process used by The Graphic Fairy but I have since found the one that I couldn't find until now and I much prefer!

    Mix together in a spray bottle 1 cup Hydrogen Peroxide, 1 cup white or cider vinegar and 2 Tbsp.salt.This mixture can be used on any metal for an aged patina, like Brass, Copper, Galvanized Aluminium or Steel.If you're aging small items like keys or hardware, you can put the mixture in a bucket and let the items soak overnight. Also, I keep the leftover mixture and just add more salt to it before reusing! It works like a charm!

      Hi Michele! I've only tried it on small items but I usually see a difference overnight. If I'm not happy with the results then I add more salt! If I was doing panels for a roof,I would experiment with a small sample piece first that way you will know what it's going to look like before you do a large area! Because you're removing the protective coating with the peroxide/salt mixture, if it's not rusted to your liking,I'm thinking it shouldn't take long after being out in the elements for you to notice a difference! I can't say for sure because I live in a totally different climate than you but I think it's worth a try!

    I have used Hydrogen peroxide, vinegar and salt mixture to rust a number of things successfully and also recommend it.
