Painting the Inside of Your Stove: Results Are in

Traderjfp, did you use the Por15 Rust inhibitor product? That one, I believe, is not rated for 1200 degrees or above....just the Black Velvet product. Could that be the issue of peeling? Thanks

There isn't much available to consumers that will stand up to the harsh environment inside a coal stove. Ceramic coating might (I've had great results with exhaust headers), but you would have to bring your stove to the company (no fun) to have the coating applied, then baked on. If your gonna go that far, I'd do the whole stove! I'm sure this would cost some serious $$$, but you'd have the only chrome-like coal stove! & it would last forever.

The sad part is, if I could afford this luxury, I wouldn't be burning coal to begin with. It's a vicious circle....

POR-15 is for rust but not for high temp but the rep said it could handle 700 degrees. I'm not sure why it failed. Either it was the heat, corrsoions, activating the ash with water or a combination.

Lots of great ideas and info. I just got off the phone with a tech guy from Stove Bright. He said that the silver in manifold paint is good for moisture but not any more corrosion resistant then the brush on stove bright paint. I guess I'll give this one more try. They sell a high temp paint with zinc too but I already ordered the brush on.

The metal expands a lot when the appliance is operated from when it is cold, that is the main reason paints and other coatings will fail.

Mathaus has had success with manifold paint inside his stove. He said that it lasts for several season and he just gives the interior a vacuum at the end of the season so I know it's possible. Here is his post: IMO it's worth the effort, but then again unless you use proper paint you might as well not bother, the two I use are VHT 2000* silver and Duplicolor 1200* silver. The aluminium flakes in the paint seem to help keep the rust from coming back, although a re-coat after a couple of years is sometimes needed.

Pic with a year of burning on the stove, 1200* duplicolor ceramic, I sold the stove after using for three years and it was still painted silver inside. Never had to coat with anti corrosion ,only vacuumed the fly ash off the surfaces.

When I bought this stove it was new but had been sitting for 8 years in a garage with no corrosion protection, the paint was applied over rusty metal after a thorough wire brushing with the angle grinder.

In the final analysis paint or no paint you will need to spend some time each year cleaning and protecting your investment.

I used the Black Velvet rated to 1200 degrees brushed on in my koker and will provide my feedback on how well it stands up next season.

I would think that the radiant heat of the firebox would far exceed 700* with a good fire going. I'd definitely use the hi-temp VHT if your going to use anything -- that's the best you can get, consumer-wise, in a can.

I believe the black velvet is also rated at 1200 degees similar to VHT.

Any feelings on Stove Bright high temp paint?

traderjfp, I hear good things about that paint....they also have a brush on version that handles 1200 degrees alongside the spray....my thoughts, based on research is that though the coal bed may sit at 2000 degrees..just off the surface along the sides of the stove probably do not reach over 1000 degrees.

Cool. I orderd the brush on. I'll let u know how it works. The work is getting the right prep for the paint to adhere. The tech from Stove Bright suggested that I sand the rust off and then wipe everything clean with Acetone or laquer thinner. It's going to be a pain. I really should take my coil out too but I hate to mess with it. It doesn't leak and I'm afraid I might twist the pipe trying to remove the coil from the stove.

You have a channing? Awesome stove.

Sounds too much like work!Vacuumed,scraped with wire brush/scraper,put a drop light(40 watt bulb) down thru the top vent,stuffed some newspaper around the opening and hoping for the best. RichB

It is but I want my stove to last 30 years!
