Gary,
i am a very srong proponent of using lime and other sensitive material in painting. I specially love lime. A limewashed room is for some reason more comfortable than a room painted with acrylic.
Not only for esthetic reasons.
I would love to have as much recepies as I can gather so feel free to send me yours
I attended a workshop in France last summer. The teacher is a traditional mason and artist. He indeed has his own recepies.
Very interesting.
Myriam
