MegaSack DRAW - This year's winner is user - rgwb
We will be in touch
As per title. I've had a good gander around the web and it seems that it's a bit of a sod to deal with. Aside from the obvious chipping and scraping options, has anyone got any bright ideas or tips for removal. It's on the collar/ceramic single wall junction and I'd rather it still looks okayish when done.
I'm replacing the cement with a different product (not putty 🙂 ) so I need a good smooth surface to apply it.
A flamethrower (or smaller) is being considered as I read somewhere that it starts to break down around 1500c mark... 😈
iron goes cherry red at 600-800deg c and actually burns at 1400. So getting the fire cement to 1500 deg C could be tricky!
I think an angle grinder might be good if you're careful.
+1 for the angle grinder. Cut a few lines in the cement the chip away the chunks, repeat till your happy.
My woodburner has this at the join between the flue and the stove, has loads of cracks and is falling off, wish I and your problem of it not going anywhere!
That's the problem - it's falling off around the gap but staying put either side of that. I'm switching to some very high temperature sealant because it's turning out nigh on impossible to stop the movement that's causing it.
Anyway - 'precision' angle grinding it is then. Thanks for the replies, guys...
