Kraken Bond High Temperature Black Fireplace Sealant 2732°F - (2x10.1oz.) Fire Resistance Up to 2732°F, High Temp Fire Caulk for Ovens, Stoves, Chimneys - Fast Dry, Paintable, Non-Flammable, 2 Pack

Worked well!

Used this to seal a leak in my Quadrafire pellet stove. It works great. Very sticky. Easy cleanup. Very durable. No drips, dries quickly and seals well.

Why did you pick this product vs others?:This sealant is silicone based and should last a few years. We are using it to seal the 1/8-1/4" gap between the door unit and the marble surrounding it.

I used this to seal a charcoal grill. It works great, and is easy to use and apply. Dries quickly.

This is the second brand I have tried. This was a little messier than the first. But the color is great. It was worked well sealing my fireplace and doesn’t crack. No bad fumes. And decent price

This stuff is legit! I had some seams open up a little in my 15 year old pizza oven. This stuff was magic!Sealed up and is working great. So happy to find this product!!

What can I say, its fireplace sealant, it showed up as expected and has been in place for less than 24 hours. Amazon has to give us time before they hassle us for a review write up.

Maybe my application was wrong, in which case I’ll change my review under user error, but I used this to seal my fireplace boot to my metal roof. The caulk literally turned into dust and washed away with the first rain. The fireplace was never even turned on, so the heat resistance aspect of the product was not put to the test.
