Cracked porcelain/ceramic

[JohnBarleycorn]

Can anyone recommend a good product for repairing a cracked cistern? I assume you wouldn't use normal bathroom sealant on such a thing.

Thanks,
JB

Araldite the best fix for porcelain/ceramics. chrisey

Or a new cistern might be a better idea!

I have never heard of anyone successfully repairing one on a long term basis.

As a temporary repair pending replacement, I have used standard bath silicone sealant on the inside but it has to be completely dry and warmed up with a hair dryer to get embedded water out.

You'd be crazy to repair a ceramic cistern and leave the house unattended.

If the crack is below (or near) the waterline don't repair - take heed of Softus's dire warning. If it's the lid then Araldite is the boy - if done properly it'll last for years.

Thanks for all the advice. It appears to be just a minor crack (very slow drip round the back, which doesn't seem to come from any of the inlet/outlet seals). I'm hoping a bit of Araldite followed by some sealant should see it through to the next bathroom refit.

At least you can't ever say that you weren't warned.

If you must repair it, than use a two part putty resin like Milliput. It works in wet conditions and as it is a putty rather than a gloopy resin like Araldite, you can mould and press it into postion until it dries - usually 1 hour.
