Wrapping tape over seams??

[Jotulf3cb]

The issue I am having is that the stove cement around my interior single wall pipe cracks and I can feel cool air when putting my fingers close to the seams in the pipe. I have re-sealed and have the same result. I was looking at the product listed below and was wondering what your thoughts are regarding simply wrapping it only around the seams.

I had air getting in where the stove pipe attaches to the flue collar on the F3. Stove cement always broke too, so I took some old door gasket and shoved it in with a screwdriver. No more air.

Looks like it should work. BTW, I like the fact that you looked into it's temp ratings - lots of folks use various items around liners etc without asking if the manufacturer intended it for the use in question.

That said, you may get a better seal on double wall pipe, which may be cheaper, and will last longer than the single wall.
