I have some hold cast iron radiators, some with nice design, that have been tested and work well, but they need some TLC. I like to keep them the way they look now, rustic, and I don’t particularly like the Silver paint that I see on other radiators. There is any clear/transparent paint or something that I can apply to protect it and that can stand the heat? I don’t know if regular polyurethane would be a good idea…
Thanks

  1. I painted mine through out my house whatever color trim I was using in the room. All Benjamin Moore latex and it’s held up fine. Been doing this since I moved in 20 yrs ago.

  2. You can get Stove Bright aerosol paints in just about any color. Thermalux makes a high temperature clearcoat, which sounds like what you want.

  3. High heat spray paint comes in white, beige, silver and black. Hardware stores tend to just carry silver or white, paint stores have all four. You can spray it on pretty thin so you won’t lose any detail in the metalwork.

  4. I have found that the best way to finish a radiator is a dull clear powder coat. The powder-coating process uses no solvents, therefore when the heat comes on there is no smell. Also powder coating is a very tough finish.

    I have had several radiators and a couple of fireplace inserts sand-blasted and powder coated by Ever-nu (my neighbor) here on 20th street. The finished product was flawless, yet retained it’s patina. Highly recommend.
