EnvirografSilicone Sealant Heat Proof Only Stove High Temperature 1250c Black

Sealed perfectly. steel stove pipe exiting through concrete roof tile. Easy to use and does the job. Used umpteen other products without success. A month gone now with deplorable weather but dry as a bone still. Yipee

Worked as per the instructions

Used this to seal a flue collar on a solid fuel stove. No discolouration , pealing, going hard and crusty so far. Stove runs 24hrs a day and flue pipe regularly reaches temp of 500 to 600 deg cCant fault it !

Only installed my wood burner about 6 weeks ago and only used it twice still warm weather so really just testing flu reached about 425c the sealant held firm and performed well will know better come next spring so far so good.

Just the job, sealed my log burner fire top and chimney,takes a bit of time to cure and needed to open a few windows for the first half a dozen fires,a lot better that fire cement

I bought this to seal the joint between the flue and the collar at the back of my wood-burning stove as the product information said it could be used on heating stoves. I allowed it to cure for three days then, when I lit the stove and it heated up, the silicone gave off clouds of foul black smoke and disintegrated to a greyish powder. The temperature at the back of the stove was nowhere near 1250 degrees and the silicone had not been exposed to hot gases or naked flames. As far as I am concerned, this product did not do what it was supposed to and was a total waste of time and money.

Sealed the join between the stove adapter and the starter pipe. Just like using normal silicone - very easy to apply and manage. Does not shift when cured, whereas the previous fire cement just crumbled away.

Easy sealant to use
