My single wall got some rust this off season. It was fairly humid this summer in CT and I made sure to put a can of Damp-Rid in the box. However, the pipe from the Jotul to the ceiling developed a nice surface coat of rust for about 3 feet from the firebox up. I'm about to remove the rust with some mineral spirits and a scrubbie and then repaint with some high heat spray. My question is twofold. Am I removing the rust correctly and am I fixing the problem correctly? Any expreience? Cheers, Goose
I don't think I have ever heard of using mineral spirits for that. I usually will scrub the rust off with a drill and wire brush attachment then clean the surface with denatured alcohol. After which I paint then cure when the stove is fired up. I have never had rust return doing it that way.
How much rust? Surface rust? Depending on how much rust and how deep, it is the anything from the above suggested down to steel wool. I used a palm sander with 60grit and Rutland high temp spray with great success.
Make sure to use a quality High temp paint. Rutland (mentioned above), Stove Bright, or Meeco's Red Devil. There are several types of Black (Satin, Metallic, Etc). So making sure you find a good match, will dictate how much you have to paint. (Good match = painting the effected area // Poor match = painting the entire pipe inside). As for prep, what was mentioned above should be more than sufficient. Just remember that good cleaning and prep, is just as important as using a good paint and applying it properly (more light coats, rather than heavy coating once or twice).
