Does anyone know if Great Stuff Fireblock in the orange can can be used directly touching a wood stove pipe? I build an outdoor sauna and i need to seal the hole around where the pipe emerges as it is getting my stove wet everytime it rains/snows. If not great stuff, what else is out there that i could use? Any help is appreciated, especially since they are calling for rain tomorrow and continuing for several days! Thanks _ nick

I don't think you want to use the Fireblock, because if memory serves me, Fireblock expands on high heat to totally block off air exchange. But in that sense it is a "one-time" use only. It just wouldn't last. You could try Rutland Stove Cement. It can take the heat, but can it take the water? I'm not sure. I'll have to check my references and get back to you.
Well i am not worried about blocking air exchange, i want to seal the opening completely. Are you saying that on continued use it would continue expanding and break apart? The sauna is a DIY canvas structure out of an old army tent, so the great stuff seemed perfect as it would be easy to apply to a non rigid surface, assuming the stove cement will withstand the water, would it be possible to apply in this situation? It seems like i would need some sort of caulk-like substance.
Put a storm collar on the pipe. That should divert the flow of water along the pipe. I'm not sure what sealant will stand up. Is this single wall or double wall pipe? Got a picture or two of the pipe exit from the inside and from the outside of the building?
