How to Paint The Inside of a Fireplace

Comin’ atcha on a Wednesday again and it feels good to be back to my old posting schedule! If read my last post, you might have seen my little note at the end about going back to MWF. I don’t really have a big reason other than I just miss the old schedule. I hope that’s ok with you guys! Anyway, today I wanted to share how to paint the inside of a fireplace. I actually did this a few weeks ago as part of our little fireplace makeover and I seriously LOVE how it turned out. It was super duper easy and fast, which makes me wish I had done this years ago. But like I always say, better late than never, right? Right. Ok, let me show you how it looked before the paint.

Super dingy, right? It certainly wasn’t the prettiest thing, so I actually made a little DIY curtain to cover it a few years ago. (I shared how I did that in this post if you’re interested.) That was great for a while, but I was getting tired of the curtain and wanted a cleaner look. So I grabbed my paint and got to work.

I did some research before I started this project and I found that you need a high heat paint to do a fireplace box. We actually don’t even use our fireplace in the front room, but I still wanted to go that route in case we ever do. Anyway, I bought Rust-Oleum High Heat paint in black and got to work.

To start I vacuumed out all the dust, cobwebs, dirt, etc. That sucker was actually pretty dirty, so I also used a hot soapy rag to wipe everything down really well. I wanted the brick to be as clean as possible before I started painted.

Once I had everything clean and tidy I got to painting. I used a roller to apply the paint to the brick and that made the job super fast. I simply rolled it on and used a small brush for the tight areas. I only needed one coat of paint to get great coverage. Although I will say that this stuff STINKS. It has a very strong odor, similar to a stain, so I definitely recommend using a mask and opening the windows. Ok, here’s how it looks now!

So much better now, huh? I was actually surprised at how easy the whole process was and I wish I had done this sooner. I think the finished look is so clean and classic. It’s makes the whole fireplace look better!

This is the kind of project I love doing–fast, easy, and instant results. The whole thing took maybe 45 minutes and I just can’t get over the difference. Even my husband mentioned how much better it looks now. And who knew painting the inside of a fireplace would be so darn easy?! I should have done this a long time ago, but at least it’s done now. Also–can we just talk about those cute benches? I picked them up from Hobby Lobby yesterday and they were on clearance. Cue the happy dance!!

Well I hope this helped if you’ve been wanting to paint the inside of your fireplace too! Also be sure to check out this post if you want to see how I painted the fireplace brick white. And let me know if you have any questions! xo

      How do you keep it clean once you start a fire in it or is yours just for looks?

    Love the way this turned out Sarah! I painted the outside brick on our fireplace but I think I’m gonna have to try this on the inside!! I love your new little benches too!! I laughed when I saw your stories because I had just told my husband that I hadn’t been to Hobby Lobby in a long time so I’m stopping in after my hair appointment today! My mom will have the kiddos so I even get to go by myself!!! Happy dancing here! 🙌🙌

    Wow, what a difference! A stack of birch logs or an iron candleholder with flameless battery candles (they even have some with remote controls!) would be really pretty if you wanted to add something to the space😊or even a basket of greenery.

    Hi. Just wanted to make you aware that your post inspired me to use this paint to pretty up my fireplace before listing my home on the market. The fireplace did not pass inspection because although this product is rated for high heat, it is not rated for exposure to direct flames and it is not recommended for the insides of fireplaces. Its also not easy to remove so I will likely have to replace the entire firebox before I can sell my home or use the fireplace.

      I was wondering it’s safe to use inside a fireplace, where the paint is exposed to direct flames. High-heat paint isn’t the same is direct flames. Bummer.

      Thanks for this comment. Sorry about your experience but this is really helpful to me. Did you find a solution? Is there a paint we can safely use for this purpose?

      Instead of painting the inside of a firebox, especially with a toxic material that is horrible for humans and the Earth, consider natural alternatives such as a layer of beach pebbles or other decorative rocks. Just make sure they weren’t coated in a flammable substance first!

    I love it! Have done a search on this before but could never find anything! I only use my fireplace 2 or 3 times a year and wasn’t sure what was safe to paint the inside with. Thank you! Can’t wait to do it!

    Hi! Paint rep here, first off it looks super good. Not trying to be negative, but the specs on that paint specifically say not for use on inside of fireplace. If it’s purely decorative that’s fine, but the paint could fail if you light a fire in there. If it doesn’t, then that’s great, but just wanted to give a heads up!

      I just did this yesterday using the spray paint. Let me tell you, the odor is STRONG!!!! Stronger than I was expecting. I’m guesstimating I had windows open for 2 hours and bowls of vinegar and baking soda all over to help absorb the smell. Sad part is, one can of spray paint wasn’t enough so I now I have to do it again. Ugh!!!

    Hi, the painted look always looks better than the dingy look a fireplace usually carries, but you should really consider removing or updating this blog post because this paint is HIGHLY TOXIC should someone decide to use their fireplace again or sell their home to someone uninformed. Significant toxicity from this type of paint inside a firebox, direct to fire vs. high-heat grills, etc.

    Hi, just wanted to say I am doing the same thing and I bought Rustoleum High Heat Paint. But I found in reading the directions it specifically states not for use around open flames. You can paint around the fireplace or grill or grate but not inside. I had to go to a specialty paint store to get paint for the interior of my fireplace. Just thought I would let you know. Otherwise,great info.

      Hi Myrna
      I would really appreciate you letting me know what you bought for the inside of your fireplace. I have spent hours researching what paint to use for this purpose. Two fireplace stores said they use the Rustoleum high heat barbecue paint but Rustoleum tells you not to use it near open flames. I’m considering Rutland high temperature paint but was just told by a customer representative basically the same story about not using it near open flames. I’m so confused. Do you have any other suggestions please? Thank you, Janis Segal

  • Thomas

    I just called rust-oleum about their high heat paint and the rep said that no of their products are recommended for inside fire places. They are heat resistance but not flame resistance. I needed to paint inside one so i called them to make sure.

    I am redoing a fireplace. I will use the fireplace. Does that paint work on brick/concrete interior fireplace wall? What type of paint was it that you used?
