Clay plaster ingredients

[Workerbee]

Hello! Does anyone know how I could make up some clay plaster to experiment with? I'm interested in trying it, but nowhere near me sells it, and the idea of paying delivery for one bag - and then having 20kg left over when I realise it's not right for me - doesn't feel right.

I'm thinking I could get a small bag of clay powder, and add marble powder, but would it need anything else? And would it matter what type of clay? I'd prefer white that I can pigment, but there are different types of clays available online for different purposes.

 

Also, has anyone here used clay plaster before? Does a skim of it help with moisture buffering, condensation, better indoor environment etc or is all of that overplayed?

 

Thank you!

I’ve a pallet full of Clay works in various colours left of from a job that had to go in a skip 

At £80 a bag Our supplier won’t sell us part pallets It’s a pain

That must have been annoying! With it being based on natural products, I feel there must be a way of making some. 

What was it like to work with, and what was the end result like?

Not really The client stands the cost 

We can order 150 bags of stone Clay works and only need a dozen burgundy colour But still have to buy 26 A half pallet 

If it’s a common colour I can store it 

But some colours are hardly ever used  by us

Has anyone else used clay plaster, and were the advertised benefits over gypsum worth it?
