Rutland High Heat Latex Sealant 800F, Seal It Right High Temp RTV Sealant and Fire Caulk for Chimney, Fireplace, and Wood Stove Pipe Repair - Flexible Heat Resistant Substitute for RTV Silicone

Perfect size to adhere the rope on my outside stove. Would buy again from the seller.

We used this stuff to seal our wood stove pipe and it definitely holds up to high temps. We only had a slight smell during the first burn or so, and a month later it seems to still be intact. Previously we had used stove cement, but that dried, cracked and fell off over time because it wasn't flexible enough for repeated expansion/contraction heat cycles.

It is better than silicone because it can withstand a higher temperature - 800 F. I used it on my wood stove pipes, just above the stove. It has a nice black color and overruns clean up nicely with water immediately after you put it on. I used some when I put the pipes together, but I still had some leaks so I put a thick coating around the pipe seam areas. When my stove gets real hot I can smell the compound as it gives off a bit of an odor. As the pipe expands and contracts I have noticed that the seam of caulk cracks(even though there is some pliability to it) and I have to re-apply to spots. Not completely satisfied, but it is better than the less expensive silicone. On the other hand this stuff is not cheap either.

I would recommend vinyl gloves rather than nitrile, the material seems to stick to nitrile better. If you wet what you are using to apply with a little water, it spreads a lot more smoothly. I haven't used it in a heated application yet, but I like the flexibility, and assuming it withstands the temperature it claims to, it will be ideal for my application.

Was very easy to apply and use! I had some areas that I applied a little to much product so it squeezed out when I screwed the stove pipe together. But still not a problem. Easy clean up with a damp paper towel. My pipes are sealed with no smoke escaping at the sealed joints. Was no curing smell either after I built a fire in the wood stove. Excellent product!

Good

Worked great to seal chimney

Why did you pick this product vs others?: The description indicated it was what I wanted. Used it to adhere the seals on my Kamado Joe smoker. I’ve use the smoker a few times since then and the seals are just fine. It does want to come out of the tube by itself, though.
