chanvre chaux (lime and hemp)

Susie is in the UK for a week so the perfect opportunity to do some messy building works. I recently demolished the built in wardrobes on either side of the main window in our bedroom and upcycled them to create new ones along one side (still awaiting doors). The gable wall is half covered in chanvre chauw, but where the wardrobes used to be is the original mess of stonework and poorly done render that was there when I arrived at Quélébu 20 years ago. I hacked off everything that was loose and fixed a batten a dado height (below this will be boarded allowing for the distribution of new electrics and hiding the central heating pipes).

I decided to try a new recipe for the chanvre chaux. Up until now I have used chaux hydraulic NHL3,5 but this time I thought I'd try chaux aerienne (the more active lime used to make lime putty in the UK).

I used a mix of approx 12.5kg of chaux aerienne, 2.5kg of chaux hydraulic blanc (to speed up setting), 25ltrs (2.5kg) of hemp and about 15-17ltrs of water. The mix is super sticky and once on the wall easy to smooth - the best mix yet! Unlike the chaux hydraulic which is rather grey, the end result is a lovely straw colour.

As I had half a bag of lime open, I used it up putting some chanvre chaux in the porch, which had been waiting for finishing for a couple of years!
