Does anyone know of any?

Over in France, the chimney from my woodburner goes up INSIDE a flexible stainless chimney liner. It is tightened down using an endless jubilee clip and the joint was stuffed with Fire-cement before tightening.

The top of the liner is close to the top of the chimney and somehow, rain gets down it. When it rerached the bottom it soaks through the fire-cement, dribbles down the chimney and rusts the top of the log-burner.

So what I'm looking for is something I can SEAL the chimney to the liner with, preferably epxy-type stuff, waterproof and heat resisitant.

Anyone any ideas?
Failing that I'm gonna have to climb on the roof, (32 feet), remove a half hundredweight chimney capping stone and somehow mod the top of the liner, some sort of cowl, maybe?
TIA

Hard to say without seeing it, but sounds like a cowl of some sort is the only really effective cure.

I've used quik-steel/quicksteel epoxy putty to stop a couple of exhaust manifold nuts from persistently working loose on my scoob, and it's withstood months of exposure to those temps (and vibrations) without a hint of cracking. Question is though, what sort of quantities do you need for the job you're talking about? I've only ever seen this stuff in 60g tubes, so it could work out quite expensive.

Iv climbed on to my mothers roof in france ( theres a hatch onto the roof , tiles ) to adjust the cowl for the very same stainless liner , i cant remember much about it but she didnt seem to have this as a problem

Would silencer cement work?

Looks like a visit to Mr. Toiture, then Wish my kids still went, actually climbing on and off the ladder makes my kn*ckers shrivel.

Any sort of cement seems to be porous to water, and that quick steel would be lethally expensive.
I'll buy a cap for the liner, they look like a chinese cooly-hat, and fit that, see if it stops it. Might cut the liner back inside the chimney a bit further too.

I just hope no hornets have made a nest inside the chimney when I get up there

I have used a heat 'proof' sillicone sealant to put the inside glass back into our oven door after i managed to push it loose whilst cleaning it.

Bought from a local DIY store which specialised in fires of all types, it will take the max heat from out oven (275 degrees) all day long and has done so for 8 or so months.

It will not rust or let water through either.

I'd have said heat proof silicone too (usually a bright red colour) or a fire-proof silicone that is used for firestopping in buildings such as http://www.hilti.co.uk/holuk/page/mo...&nodeId=-85775, might work.

Make sure you don't get the cheaper stuff, and make sure it isn't an intumescent product that expands when heated - the last thing you want.

It never seems all that strong really. We have to keep replacing around the fireplace indoors and I don't know how well it would stand up to water.
