Lime Render internal walls

In Italy it can be tricky finding the right mix for lime rendering which your average Italian plaster scoffs at because it is slower to work with and doesn't give razor sharp angles that the new stuff which is usually mixed with cement (and therefore doesn't breathe either).

Randomly I found this recipe on the wonderful Renovating a Gite in Brittany blog:

"The lime render is made up of just lime (Chaux blanche hydraulique naturelle), sand and water. The instructions on the bag said one sack of lime (35kg), 11 buckets of sand (10L buckets) and two buckets of water."

and judging by the results it works just fine!
