Faux Cast Iron Finish

I developed this paint technique to create a cast iron finish on a HID-E-OUS brass lamp we had in our living room.  My husband and I have a lovely cast iron legged side table and a shared like of Restoration Hardware.  Also a shared like of not spending that type of money.  I tried to find a good tutorial to fake a cast iron finish but gave up and started playing with paint.  After multiple attempts, hauling the side table around to compare, and scraping off bad finishes I found a way to paint a faux cast iron finish.

Faux Cast Iron Tutorial

 

It looks great on furniture but also works to make an ‘urn’ like finish for Halloween.

Supplies

Supplies to create a faux cast iron finish.

 

For the basic finish you need:

Rustoleum American Accents Stone Finish in Mineral Brown* (long enough title?)

Bronze Spray Paint*

Matte Clear Finishing Spray*

Sand Paper (higher grit is better for smoother finish)

If you want to paint glass:

Add a glass primer or frosting spray*

Step 1 We All Hate It: Priming

Depending on the piece you are covering you’ll need to prime it.  Glass required a coat of frosting spray.  My horrible brass lamp needed a clear coat sanded off.  Google directions for the piece you want to cover.

Step 2 Using the Rustoleum American… Ah to hell with it: The Stone Paint

Faux Cast Iron: Spraying Stone

I’m just going to call it stone spray paint from here on out.  The title in supplies should let you know what I mean.  By the way, I am only suggesting that particular brand for the stone paint because it is the only one I have used.  I tried a variety of bronze paints and they worked fine, but I haven’t had a chance to try a different texture brand.  If you do please leave a note in the comments.

Lightly cover the whole piece with a splattering of the texture.  I moved waaaay back than my usual spray painting technique.  You can see if just splattered a coating.

Step 3: Bronzer instead of Blush

Cast Iron Paint Finish: Adding bronze

You can go ahead and spray a covering coat of bronze spray paint before the stone paint is dry.  Save some time and it doesn’t hurt anything.  However, let the bronze mostly dry.  I say mostly because I am impatient and if it is a bit tacky and peels up you’ll be fine. If you are doing it right it will look shiny and warty and you’ll be thinking “what the hell is this?”

Step 4: More OMG This Looks Awful

After the bronze ‘mostly’ dries take the sand paper and give it a buff.  It will knock off a lot of the texture leaving pits, holes, and scuffs.  Then cover in bronze paint again.  Repeat step 3 & 4 if you don’t feel like it had a lot of varied texture, or you were impatient (like me) and gummed up the paint into a wad.

Step 5: Now It Will Come Together

Finishing the faux cast iron finish
From What? to Wow! all in one coat of paint.

Let everything dry and then cover the whole item with a thick coat of matte spray.  By thick, I mean disregard the manufacturers guidelines and get that puppy about 3-6 inches from the surface.  You want the matte paint to pool in the pits and any decorative carvings.

That is pretty much that!  There aren’t really notes with this process other than more layers of paint give a richer finish.  You can see how I styled these cast iron ‘urn’ vases for a Halloween Vignette.

The final finish has a lot of texture and is matte in nature like real cast iron.

  1. In the last photo you say put a heavy coat of matte paint on and ignore manufacturers instructions, OK, what matte paint? Did I miss something? Another color coat? Matte Clear?
    Help!

  2. I have a cast aluminum patio set which I have just spray-painted Matte Black. I was trying for the cast iron finish, but obviously missed it. Would I have to re-prime this furniture before applying your process?

  3. I have a 3D printer and I am going to print a plaque for my friend and want it to have an iron effect. I will print it with a magnetic material to add to the effect and then do this process and hope it looks as awesome as yours!

    • Well mine turned out to look exactly like cast iron. It is easier to achieve if you have a small piece to compare too. I’d love to see the finished project!

  4. This looks fantastic! I’m just flirting with the idea of building some super simple French industrial-style furniture. You make it look easy, but do you have any advice for a rank novice?

    Also, it would be great to see the finished product next to some real cast iron, and better yet in a video.

    • My best advice is to have some cast iron or google some photos of it while you are working on it. Also do not panic if one of your steps goes awry, you can always paint or sand it and start over. SOme of the best finishes come from ‘Mistakes’. I will definitely look into making a video of the finish at some point when it is warmer and I can spray paint outside.

  5. Brianna, So happy to have found your cast iron tutorial! I too have a thing for cast iron. I’m in the middle of redecorating my living room and rescued a long wooden console table that I’d like to give cast iron legs. Would your technique work on wood as long as it too is primed?

  6. What a fantastic tutorial! I am making a fireback out of epoxy and wanted to make it look cast iron, not wanting to master the lost wax technique. This is super helpful, thanks!

  7. Brianna thank you SO much for sharing this last week last week on the Making Monday link party. I wanted to let you know that I was going to feature this for this weeks link party and would really love it if you would come grab a button and link any other projects you have! Hope to see you soon :) and thanks again http://gracelangdon.blogspot.com/

    • Thanks! It took quite a bit of trial and error. Any time I work on a faux finish recipe it helps to have a real example to mimic.

  8. Love this idea-just hope no one thinks the glass vases ARE bronze,
    and breaks them. I need to re-do some brass knobs and love this color-will
    let you know how this works-will need to ..ugh…prime first.
