Rendering for the inside of a fireplace
 

One more (ta in advance and all that)

I have to render the inside of a fireplace, in order that a wood/coal
burning iron stove can go in later.

What would be the recommended mix for that? Something with lime maybe?

On an aside - I'd like to "paint" it white. Paint's not going to like the
heat - so I thought of whitewash/distemper - basically something white,
paintable and lime based. Is that something I could make starting with a
bag of lime? Google's not being helpful with regard to just
buying "whitewash" and "distemper" is more of a doggie disease(!)

Nearest I could find was this:

Are whitewash, limewash and distemper all the same thing?

Whitewash/limewash same thing. Distemper includes linseed oil I think.

You can make whitewash from a bag of builders lime (£5/bag and one bag
will last the rest of your life) - mix with water in a plastic dustbin
and leave as long as possible (days/months/years) - this will give you
lime putty at the bottom, with excess water on top. When needed, swirl
it up and scoop off some of the whitewash. Coats should be painted on
so thinly to be semi-transparent when wet. Build up lots of coats.

Genius - thanks for that. Better start my bin of putty soon then.

An old plasterer told once me the best way to neutralise soot, and get it to
accept plaster, is to mix cow dung with water in a bucket and paint it on.

Do a smooth render with white cement and washed playpit/silver sand.

Don't bother painting,

Fascinating! I'm almost tempted - plenty of cows round here, somewhere...

That's an original idea. Could it still be worth shoving a bit of lime in as
a plasticiser?

If you want.
Not sure if we did. However it does get dirty fast ;-)

We were advised by the wizened and experienced stove man to go for a
weak mix (5 parts sand to one cement). When this was dry, we painted
it with normal paint.

Since then, we've had the stove on quite a bit (last night...in
July...) and no problems.

I'd ask Anna Kettle about this, but I'm fairly reliably informed that
any old recipe for cow dung related plasterwork needs care if you use
modern dairy output. It's the change in diet and hyper-breeding of
cows that resemble industrial fermenters. If you're "shopping" for
cowpats, take them from the fields where the bullocks are, not the
milking parlour or the slurry lagoon. If you do use dairy output,
check that the water content is still what the recipe expected.

Errors in this area may leave you with a bathtub full of extra-runny
wattle & daub mix that refuses to stay daubed and gets stinkier by the
day...

Some timely feedback is due I think.

I followed your suggestion, using a 1:1:5 of snowcrete (white portland
cement), lime and playsand.

I wirebrushed the crap off the fireplace (wasn't too sooty save for a few
spots) and primed with a wet cement slurry.

I made the render fairy sloppy (the lime certainly helps hold it togther)
then applied.

It worked pretty well. It dried to a very light beige and looks quite
natural. Job done - thanks for the inspiration!

Cheers
