This link has some useful info;

There is a page on the French Entree site which has some useful info

We have found the French plaster to be a complete nightmare to work with and nothing like the nice brown and pink plaster that you get in the UK. French plaster seems to 'go off' at the drop of a hat, but we have found that mixing it 50/50 with some 'Colle pour plaque de platre' delays the hardening effect somewhat. But unfortunately, no matter what we do, it still seems impossible to get a nice smooth finish on things like plasterboard, so we have had to settle for the 'rustic look instead!

thanks dinks

 

fortunately we are after the rustic look .....but i want to be sure i get the right plaster to allow the walls to breathe

just as an afterthought ...presumably the paint needs to let the wall breathe too....any recommendations??

I believe you should use "chaux" (lime plaster) plus local sand (as said above) to achieve the correct colour - then paint should be unnecessary.  However, "Fired Earth" make traditional breathable paints although they are mega -pricey.  You can get small test pots to try out the colours and they do have French distributors.

does anyone know in what proportions the above should be mixed??

In my 'half-bag' mixer I used half a bag to 13 full (heaped) shovel fulls of sand.

This was after measuring the sand with a bucket, as per the instructions on the bag..
