Black, 10.3 fl oz Cartridge Furnace Cement, 10

This is the product one needs to re-attach wood stove door gaskets and similar items. It works.

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.

Good high temp cement, NOT adhesive, but fills in cracks on pipes and adapters

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.

Repair my wood stove furnace. Had a crack in the back. Sealed up the crack and got my wood furnace back going.

Yikes. Ceramicists: Do not use on your kiln ! I thought I would reinforce my cracking top to my Paragon kiln... so I spread a layer on top. The product warped upwards and pulled large chunks of the kiln brick with it. :(

It works, and easy to be used.

Stuff works very well.
