Ian Posted July 26, 2017 Share Posted July 26, 2017 Now that I have the replacement baffles for my WBS, I have to re-assemble it.Some parts were joined/sealed by a cement-like substance (very hard). Obviously fireproof...I seem to remember fire cement, in the UK, available in ready mixed tubs, but the only similar thing I can find here in France is "ciment refractaire", in powder form.Is that suitable? If not, what should I use?Thanks Link to comment Share on other sites More sharing options...
cajal Posted July 26, 2017 Share Posted July 26, 2017 Several years ago I bought a tube of mastic réfactaire from Bricomarche, 'Pyro Feu'.Resistant a la Flame et jusqu'a 1500 °CMontage entretienFoyersInsertsPoêlesCheminéesIt's applied using a standard mastic gun and it does what it is supposed to do. I would recommend it. Link to comment Share on other sites More sharing options...

earlesssensible Posted April 7, 2023 Share Posted April 7, 2023 In the United Kingdom, fire cement came in pre-mixed tubs, but in France, the closest thing I've seen is powdered "ciment refractaire." phrazle Link to comment Share on other sites More sharing options...
ssomon Posted June 25, 2023 Share Posted June 25, 2023 (edited) I don't know the temperature where you have to seal, but I successfully sealed the flue connection on the back of our pellet stove to the flue using high temperature (black) silicone sealant. It is still OK and flexible after 12 years. The mean flue gas temperature is quoted in the manual as 218C, but I've never measured it.
