Rutland Products Black, 10.3 fl oz Cartridge Furnace Cement, 10

Used this on a vent pipe from hot water heater to the chimney in the basement. Easy to use and was solid as a rock the next day. So make sure you have the position you want it in. Sealed perfectly and I'm quite happy with the out come.

worked well!

Used on pellet stove for ceramic fire insulation. Works well to adhere insulation to stove.

Be sure to squirt a good amount of product out on a paper towel or something before using. When I opened and squirted a little test amount to see the color and texture, there were pockets of black liquid that came out, probably from bieng stored upright and some separation of the product. I would have been upset had I just cut the tip and started dispensing on my situation, that black runny liquid would have dripped on my brick hearth. After dispensing a bit of the product the pockets of liquid stopped coming out.I just needed to seal a several small holes in the flue pipe where I had to modify the crimp with sheet metal snips to get it to fit in the flue collar. Somehow 8" today is bigger than 8" 30 years ago? Maybe a metric thing...probably no longer an American made new flu pipe.This full tube was less expensive than the little hand tubes, and hopefully my capping it will keep it viable for some years as I take apart this connection twice a year to cap and uncap the flu, otherwise the downdraft we have will fill the house with the smell of creosote in the off season.My stove connection is not the prettiest, but few notice it. However I think the product dries fairly black but not "black-black". Someone else reviewed that it was gray when dry. I attached a picture of a dab after being properly fired to at least 500 degrees as the instructions say. You can see the black of the flu pipe is actually less black than the stoves flu collar. So yes, if you are sealing your "black-black" stove, you are going to see a color difference. It matches this flue pipe almost exactly though. My wood stove is for heat, not show, so as long as it does its job, it's all good. Those little holes were letting out tiny sparks right in the direction of my paper and kindling!

Was good for fixing the hole in the stove pipe for our woodstove. Better wear a pair of gloves. You can’t just use a tool. You have to actually spread it around by hand.

This did a great job to adhere bricks back onto my fireplace. I would highly recommend.

I used this on a chiminea that had split. It did not hold even after the cure time recommended. I never even fired it before I realized it didn't work.

Excellent Product Thank You
