The outer face on a triple wall chimney should not get past slightly warm t
o the touch unless the OP has a roaring fire. The sun sh8ining on it will
bring the temperature much higher. I am sure he/she wants to hide the brigh
t glare coming from a stainless chimney on a bright sunny day. Almost all
the suggestions to date don't take into account that the chimney will be ex
posed to a wide variety of temps and weather, and can't be brought into a p
aint shop and then reassembled on the roof. A spotted chimney may look eve
n worse than a consistently shiny chimney.
It happens that my triple-wall stainless steel chimney was in the category
of producing glare. I chose to build/enclose the entire chimney in a wood-
based simulated brick housing that from the ground looks like real brick, a
nd does not reflect sunshine into any of my neighbors faces. I do have to p
aint the trim every 4-5 years, not a big deal.
I had to paint the lower part of my chimney that stuck down below the
ceiling. Mine is triple wall stainless too. I simply scuffed up the
outside of the pipe and sprayed it with the black paint used for repainting
woodstoves. It's a high temperature paint designed for that purpose. I
bought mine from the same place we bought our woodstove.
After ten years there is no sign of peeling or flaking. It still looks the
same as when I first painted it. Of course, that's indoors, I don't know
how well it would hold up outdoors.
Ditto. When we installed our wood stove (ca 1985) I used Metalbestos
insulated chimney which is stainless steel inside and out. That portion
of the insulated chimney below the cathedral ceiling is painted with the
same flat black, high temp paint used on the plain metal chimney
extending up from the wood stove. It's been painted ONCE and it still
looks just as good as the day it was painted.
Above the roof we did the same thing, only with Rustoleum, high temp
(for no particular reason), flat black and we've spray painted it about
four times during that same period. It really needs a recoat now but
it's probably been at least 12 years since I climbed up there (or had
the inclination to do so) to paint it. Maybe this year<g>
In any event, the coverage is still about 85%.
I did no special prep on the SS other than to wipe it down with whatever
thinner was recommended to remove oils etc.
