Customer Reviews for Mapei Mapeflex Firestop 1200°C High Temperature Sealant Grey 300ml
Review 1 for Mapei Mapeflex Firestop 1200°C High Temperature Sealant Grey 300ml
"I was under the impression that this was quite flexible but less than 1 week after sealing the flue to the wood burner it cracked, I shouldn't be surprised as it is fast drying and water soluble, it seems to me that it is exhaust paste in a mastic tube, how long it will stay in place is uncertain, but the previous exhaust sealer lasted 2 years, let's see!, it does make it easy to squeeze into small gaps and at 1200c it is the highest I have found as I don't know what temperature the wood burner burns at."
