How to Paint a Radiator the Easy Way!

My old house has many enormous, clunky, old, and disgusting radiators.  Slowly but surely over the past couple of years, I’ve been painting them to hide years of neglect (think chipping paint and/or rust spots), or poor paint color choices from previous owners (think mustard yellow).  I can honestly say that, until recently, radiator painting was my LEAST FAVORITE JOB IN THE HISTORY OF THE WORLD.

I’m not being dramatic.  It was tedious work that provided little visual impact, especially for the amount of time it took to complete a single radiator.  Each of the medium-sized radiators I brush painted took about a week of half-day painting sessions to complete.  A week of stinky oil-based paint smell in my house, blocked off areas so that paint would not get smudged, and the mess that accompanies any painting job.

Needless to say, I was really dreading painting the radiators in my living room, which were gigantic yellow monstrosities.  Here’s one . . . Radiator painting can be time consuming and tedious, but not with this tutorial! Lean how to paint a radiator the easy way! Save time and frustration. This is a BEFORE photo.

And here’s the other. . . Radiator painting can be time consuming and tedious, but not with this tutorial! Lean how to paint a radiator the easy way! Save time and frustration. This is a BEFORE photo.

I figured that each of these yellow beasts would take me about two weeks to refinish.  And that’s why painting these radiators kept getting pushed to the bottom of the to-do list.

But now I know the SECRET of how to paint a radiator the easy way, and I am so glad to tell you that this method is life changing.  Seriously!

Supplies Needed to Paint a Radiator the Easy Way

Thank you to HomeRight for providing product used in this post.  The project and opinions are all my own.  Also, this post contains affiliate links.  To read my full disclosure policy, please click here.
  • The KEY to painting a radiator is a spray painter.  I am telling you that it makes all the difference in the world (and is MUCH cheaper than hiring a painter to tackle your radiators).  I used the HomeRight Finish Max Fine Finish Sprayer for the first radiator I refinished in this room, and the HomeRight Finish Max Extra Fine Finish Sprayer for the second radiator I refinished in this room.  Both sprayers worked great for refinishing radiators, but you can read about why I liked the Finish Max Extra Fine Finish Sprayer more in the update portion of this post near the end!
  • 3M Advanced Masking Film
  • Scotch Blue Painter’s Tape
  • Spray Painting Mask (I wore a head sock like this; no joke.  I didn’t post a photo of myself in it because I looked a little bit like a murderer or a terrorist.)
  • Rustoleum Metal Primer
  • Rustoleum Protective Enamel (I used a Satin finish)
  • Acetone (for thinning the oil-based paint to use in the sprayer)  (NOTE: if you use the HomeRight Finish Max Extra Fine Finish Sprayer I talk about in the updated section of this post below, you will not need Acetone.)
  • Mineral spirits (for cleaning up the sprayer once you’re finished)
  • Wire brush
  • TSP
  • Vacuum with hose extension or long feather dusters

Instructions for How to Paint a Radiator the Easy Way

Begin by scraping any loose paint areas from the radiator by using the metal brush.  (VERY IMPORTANT:  YOUR RADIATOR COULD HAVE LEAD PAINT ON IT.  MAKE SURE TO USE ALL PROPER PRECAUTIONS BEFORE SCRAPING PAINT, AS INHALATION OF LEAD PAINT CAN HAVE SERIOUS HEALTH CONSEQUENCES.  TO LEARN MORE, PLEASE VISIT THIS LINK.)

(TIP 1: Make sure to do this job at a time of year you’re not using the radiators.)  Radiator painting can be time consuming and tedious, but not with this tutorial! Lean how to paint a radiator the easy way! Save time and frustration.

Next, clean the radiator like the Queen of England is coming to visit and her butler will be giving the place a white glove inspection.  Begin by vacuuming as much dust off of it as you can, and then washing it down with TSP.  Once it’s dry, dust it again.  I promise you, it will still be dirty.  Radiator painting can be time consuming and tedious, but not with this tutorial! Lean how to paint a radiator the easy way! Save time and frustration.

After you’ve cleaned the radiator, protect the entire area around the radiator with the masking film.  Tape it everywhere.  The last thing you want is oil-based paint all over your walls or floors.  The masking film is actually really easy to hang and goes up pretty quickly.  I told my kids it was our new curtains; they were not impressed.  Radiator painting can be time consuming and tedious, but not with this tutorial! Lean how to paint a radiator the easy way! Save time and frustration.

Once you have the entire area protected, set up your sprayer and thin the primer according to the manufacturer’s directions.  (NOTE: if you use the Finish Max Extra Fine Finish Sprayer I talk about in the updated section of this post below, you will not need to thin the primer.)  Then spray the entire radiator with primer.  It will already look a million times better!

(TIP 2: If you’ve never before used the sprayer you’ll be using for this job, you should test it out on a piece of cardboard first.)

(TIP 3: Oil-based paint smells REALLY really bad.  Make sure you have the windows open and a fan going when you do this.)

Let the primer dry according to the manufacturer’s directions, and then spray the protective enamel on as the topcoat.  Smile at your spouse or significant other because you’re so happy with the way this project is going!  Seriously – you will not believe how much time you’re saving because of using the paint sprayer.Radiator painting can be time consuming and tedious, but not with this tutorial! Lean how to paint a radiator the easy way! Save time and frustration.

Once the entire radiator is sufficiently covered, clean the paint sprayer like the Queen’s butler will also be giving it the white glove inspection.  Prepare yourself that it will be a pain, simply because you’ve used oil-based paint for your radiator painting project, and oil-based paint is chronically frustrating and time consuming to clean up.  Still, even though the clean up process is a bit involved, the entire project can be completed in less than a day, which is SO MUCH FASTER than hand brushing a radiator.

The finish is SO smooth (unlike the finish on the radiators that I hand brushed), and I am thrilled with the result!  I vow to NEVER paint a radiator by hand again.  Never.Radiator painting can be time consuming and tedious, but not with this tutorial!

Thank goodness the mustard yellow radiator paint is gone!  Radiator painting can be time consuming and tedious, but not with this tutorial! Lean how to paint a radiator the easy way! Save time and frustration.

I still have one of the radiators in my living room left to paint, but I’ll get that done in the next month or so.  I wanted to make sure this method actually worked before I tackled both of the yellow beasts at once!

UPDATE: AUGUST 2017

Although I planned to spray paint that second radiator last fall, I didn’t get around to it before we turned the heat back on.  It all worked out in the end, however, because HomeRight came out with a brand new version of the Finish Max Sprayer, the HomeRight Finish Max Extra Fine Finish Sprayer, which has a few more features that made radiator painting even easier!

The feature I liked best about this new version of the sprayer is that I didn’t have to thin the primer, and I only thinned the radiator paint a tiny bit (and just as a precaution).  I don’t even think thinning the paint was necessary; I only thinned it a little because I still had acetone left from the radiator I spray painted last year.  Not having to thin the paint and do straining tests to see if it will work in the sprayer was a huge timesaver!

I also really liked that this new version of the sprayer has a flow control dial built right in, so I could easily adjust the amount of paint coming out of the sprayer depending on which part of the radiator I was working on.  The Finish Max Extra Fine Finish Sprayer also comes with different nozzles and air caps so it can be used on a wide array of projects like cabinets, furniture, fences, decks, and more.  It is definitely versatile!

I took my yellow radiator from this . . .

even faster than I did the first time around.

I cannot emphasize how much easier the the HomeRight Finish Max Fine Finish Sprayer and the HomeRight Finish Max Extra Fine Finish Sprayer made this job.  Anyone who knows me heard me complain about hand painting my radiators in the past.  I promise that all anyone’s heard about this project is how wonderfully easy it was!  If you have any radiators to paint in your home, I would absolutely recommend that you use this approach to paint them – do not hand paint them.  You will want to pull your hair out!  Radiator painting can be time consuming and tedious, but not with this tutorial!

Have you ever painted a radiator?  Did you think it was a terrible job, too?

    Wow! It looks really good. That is one job I’m glad I don’t need to do. Had those in my old house and what a pain. This sounds MUCH easier, even with all the prep and cleaning the sprayer. It really looks beautiful now:)

      Katie it has made SUCH a difference in the living room! I still have to paint the other one in the front of the room, but that is happening so soon. I am not exaggerating – it was life changing using the sprayer vs. brushing the paint on. I am so grateful for my sprayer!

    Very silly question – how did you get to the back of the radiator or by spraying, did it simply cover up anywhere where there was visible yellow?

    Also, how did you clean the sprayer? Soapy water?

    We will be embarking on this project this week and I am curious and needing all the help I can get.

    Thank you!

      Hi, Tanya! OK, so I did not paint the back of the radiator because you can’t see it at all. I don’t think there is a way to brush paint the back either . . . unless yours is somehow not up against a wall! I just covered everything that was visible.

      As for cleaning the sprayer, since this required oil based paint, I used mineral spirits to clean it all up. The cleaning part was the worst of the entire job. Latex paint is super easy to clean in the sprayer, but the oil based paint is trickier for sure.

      That being said, it was still SO MUCH EASIER and faster than hand-painting those radiator beasts! If you have ever hand-painted one then you know what I’m talking about! Good luck with your project and let me know how it goes!!

    Hi! Which enamel did you use-gloss, satin or flat? And for that size radiator, how much primer/paint? I have several to do, so want to plan accordingly. Thanks for the post!

      Hi, Ceili! I just double checked and I used the satin enamel. I really like the finish it gives! I used about half a can for the large radiator. Good luck with your project; I hope it goes well!!

    Just wanted to see if you are still liking the radiators? I noticed that you didn’t use a high-heat paint or special radiator paint. Have you had any chipping or bubbling?

      April 10, 2018 at 12:12 pm

      Hi, Emma – they are still GREAT!! I used the same type of paint on every radiator in my house throughout the years, and they’re all working wonderfully and I’ve had zero problems with bubbling. One of them has a small chip where the cleaning lady bashed the vacuum into it, but that isn’t the paint’s fault. I think the thorough cleaning and priming before paint makes a difference. Also, I did research before painting them and found that high-heat paint is not necessary for radiators. High-heat paint is for devices/items that get much hotter than radiators do, so it’s unnecessary for this job. Good luck if you tackle this job!

    What did you put on top of the radiator? Is that wood?

      Yes! We have wood toppers over the radiators so that you can sit on them (like benches) or set stuff on them.

    Thanks for this post. Really appreciate the information you have here. I know it’s an older post but I hope you don’t mind if I ask a question. Why did you use oil-based paint? I’d much prefer to use water-based if possible. I live in an apartment with four of these beasts and cleaning up an oil-based project will be really difficult. Thanks again.

      Hi, Jennifer! I used oil-based paint because typically it is better for metal applications. You definitely can use latex paint on radiators, but they’re more prone to chipping and the finish probably won’t last as long. That’s what I read when doing my research at least! I hate painting radiators so much that I wanted to have the paint last as long as possible, so I took the annoying and stinky way of doing things! Thank you!

      Hi, Jimmy – no they did not. There was a significant amount of time between drying and when I turned them on, so there was no odor.
