RUTLAND PRODUCTSBlack, 10.3 fl oz Cartridge Furnace Cement, 10

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

I recently cleaned out my gas fireplace and discovered that one of the logs was cracked in several places and just about to break apart. After trying to research repair or replacement online I read that this stove caulk could be used to repair bricks and ceramic fireplace logs. The logs in my fireplace are not connected to the gas line but are for decoration only, so repairing them seemed like a safe option. After I got my caulk I took the log outside and placed in on newspaper anchored with stones, then squeezed out a few inches of caulk and rubbed it into the cracks on the log with gloved hands. The caulk didn't stick well to the porous ceramic of the log, so I rubbed it on generously, trying to force it into the cracks. Then I placed the log on a foil-lined baking sheet and put it in my oven and turned the temperature up to 500°. I let it bake at 500° for about 45 minutes and then turned off the oven and let it cool down naturally. A couple of hours later I took it out and it was nice and secure and no longer in danger of splitting apart. I suppose if I wanted to be really fancy I could buy some high-heat brown spray paint and paint over the black caulk, but it's not really that noticeable in the dark interior so I don't think I'll bother.

With Spring here it was time to clean out our woodstove pipes. Which mean complete disassemble of all the pipes and removal of any furnace cement. I drove down to our local HD in search of a tube of Rutland Furnace Cement only to find out that they no longer stock it on the shelves and transferred it to online only. With that being the case I did some searching on Amazon and found the tube cheaper than HD so I went ahead and bought it here.What I really like about this furnace cement is that you can use a dull chisel or screwdriver to remove it when it’s time to clean after the season is over. The tube is easy to use and has more than enough to last a couple seasons.A couple things I need to mention about this tube is that…..……you need to cut a small hole on the tip (roughly 1/8”) anything bigger you will lose a lot from pressure squeeze out unless you remove the pressure every time after you squeeze the trigger..…..also the initial first squeeze on the trigger will push out a small amount of liquid so be prepared for that..…..mask off anything you don’t want the cement to adhere to (plus makes the job a lot neater)..…..use gloves, this stuff stains your fingers black..…..having a damp paper towel or rag to clean up immediately is extremely helpful....…most importantly you MUST start a small fire to cure the cement with heat.

The ceramic log in our fireplace broke during one of little Calif. earthquakes. With two pieces I could not get the log to sit properly on the small edge that holds it. After looking around for a glue type to put the two pieces back together I found this cement that can take high heat. I tried to put the two pieces together as was shown on the tube, but this did not work. It mentioned to let it sit half an hour, which just fell apart. After looking on their website, I finally put the cement on the two pieces of ceramic log and tied together. Leaving this for 24 hrs. until it set. I then put it in my oven and set it for 500 degrees to heat set the cement. I am very happy that this worked and now the log can be used as one piece.It was not that easy to do and the directions were not very good. Also, when I went to research the product after receiving it, I saw the price had been reduced, which was annoying. Over all it worked, soI am giving 4 stars. I wish I had found a glue or epoxy to use, it would have been easier. The three stars are for it being hard to use, having poor directions, and the reduced price the day after I purchased it.

worked well!

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.

It was fairly easy to use - always messy putting stuff like this on but could be worse. I got this because it literally says the colour is black. Well, it goes on black. But you have to heat it up to cure it - after heating it up exactly the way the instructions say (slowly getting a fire going in the fireplace), the stuff turns grey, so it doesn't match the fireplace insert colour anymore. It is still in place, it seems to be heat resistant, hasn't crumbled and fallen apart. So overall it seems to work as intended and if you aren't picky about appearances it seems fine. But there should be a warning label or something about how it doesn't stay the same colour after curing, seems like misleading advertising.

Had some cracks in the firebox of my wood stove. Had been looking for a welder to fix those, until I saw this product. Applied it to the cracks and a couple of broken fire bricks. Then started a small fire and kept that going for a couple of hours to cure the cement. Now it is rock hard and no more air leaks. Saved myself a lot of $$ by not having to hire a welder.
