Kraken Bond Fireplace Sealant, High Temperature Black Fire Caulk up to 2732°F - Flame Resistant Stove, Chimney & Oven Sealant - 10.1 fl oz Cartridge, 1 Pack

This stuff really works! I needed a sealant to fill the firebox door of my gas furnace, it cracked from top to bottom. This stuff (Kraken Bond) is good to over 3,000 degrees F and sets / cures when exposed to heat so it's a no-brainer to seal a gas furnace burner access door.

Worked well with sealant tool/gun, purchased separately. Couldn't find black at Lowes so bought this here at Walmart, it was a good color to seal around our gas fireplace thats black with black marble around it, we used it for inner part where gas insert met the wall and marble slabs. Was easy cleanup for smudges with damp towel. Would buy again, definitely recommend.

I have an older wood burning stove and every year I do a seal to prevent smoke drifting through the seams and this does the trick. Definitely recommend!

worked good for what I wanted on my woodstove

easy to use container. simple straightforward. great product

Exactly what I needed to seal the joints on the stove pipes for my wood stove. The only reason for 4 stars was it was difficult to get out of the tube, and the product dried rapidly. Maybe the tube was old, I don't know. I had to work fast. Otherwise, the product is excellent. It sealed and resists the high temperatures of the stove.

Product arrived as promised and as described, we just installed used it on our wood stove pipe a few days ago so far so good no smoke leaks going to attempt to use it when we change the fire brick and the door seals also, however we've not had a real cold not yet so Fingers crossed cause nothing else is held up yet. Will buy again if it does well . Will update this when I know.

dried and sealed as i expected it to. good product. minimal shrinkage. but very sticky. i recomend wearing latex gloves.

Did not like that there were no use directions listed on the product. I had to do an extensive online search for assistance

The caulk has a shelf life. It expires in 5 weeks. Lotus is selling old inventory.
