Need High-Temp Paint for metal fireplace Q&A
Q. I have a gas fireplace with brass doors. The brass doors discolor terribly.
Does this mean I need a clear coat?
What should I use?
I'd appreciate any help.
Thanks.

A. Hi, Peggy. Bright brass is always lacquered or clear coated. It turns brownish if it isn't. Some people prefer the brown look, but if you want it shiny you must lacquer or clear coat it. Brass lacquer is designed for use on brass and is easily removable so you can re-do it or change your mind. Lacquer is flammable, so don't do it near an operating fireplace, and let it dry.
You can buy single rattle cans of brass lacquer [on
eBay or
Amazon]
, but if your needs are special or for larger volumes, please contact

It may be that black paint is more appropriate though :-)

Q. I would like to faux finish (marbleize) my metal fireplace. Is there a heat resistant paint that I could use?

Q. We have recently had a gas fireplace installed and they vented it with a fan that goes onto our patio. It is currently shiny aluminum in color, and I would like to know if there is a light beige or tan color in a heat resistant paint available.

A. Hi, folks.
Marcia, I'm not aware of "fancy" finishes like marble being available in high temperature paint. But whether you need high temperature paint may depend on exactly what you mean by metal fireplace. If it's a wood stove, you'd definitely need high temperature paint; but if it's a metal surround around a fireplace, fancy paints like "American Accents" might survive it fine.
Jim, I think you'll find high temperature engine paints come in a color that you find satisfactory.
Barbara, paint doesn't stick well to aluminum, so before your high temperature paint you probably need a self-etching primer. Good luck!

Q. I operate a gas fireplace service company and have a need for a high-temperature, black paint that will stay black.
Water vapor is a by-product of the gas combustion process within direct vent gas fireplaces and these units are, in turn, beginning to rust after 3-4 years of use. The run-of-the-mill, high-heat, black Rustoleum paint oxidizes within the firebox when the unit is used and turns white. So, the recommended method of fighting the rust in direct vent gas fireplaces by sanding and repainting is resulting in unhappy homeowners when the new black paint on the black metal firebox turns white. Any ideas?

A. Sounds like an application for a black oxided stainless steel.

A. There are many types of high temp paints on the market. Unfortunately, they all have one common problem. The corrosion resistant part of the paints are affected by heat and they lose their ability to resist corrosion after heating. What's the answer? A barrier type high heat coating. Use a coating with a high Mica content as a primer and topcoat with a good high heat enamel. An aluminized high temp primer will serve the same purpose.

A. Maybe high temperature paint [affil links]. Good to 1200 °F
