Weatherproofing clay?

I stand corrected, I had assumed that if there was sufficient coating of concrete it would be water tight however sodden the outer layer gets, perhaps its not as fine granuled as i suspected

Right-o
What if I rendered it after a season of use and kept dry (this is Perth Western Australia - it won't see much rain in summer!) so there is no moisture to get trapped?
Maybe a little tin roof is the easiest option - make it look like a dunny, eh?

Aussies definitely understand him to mean the top one

But yes, a small roof over it (which the flue has to pass up through) would be fine. Your climate in Perth is much more suited to that than ours is. Just render with a standard lime render - lots of recipes available on the web.

Cheers,
