It says made from dolomite limestone, is
this the limestone I need for making lime plaster and lime paint? If not, where could I find an inexpensive source of hydrated lime in central Oklahoma?I know, dust safety means a breathing mask, lime handling safety means skin fully covered with clothing and (ugh) rubber gloves. Along with
building sand.
If so, would I use one bag of limestone to one bag of sand with enough water to mold it into a ball? If not, what ratio would I need?
How thick would it need to be to waterproof a cob wall? 1/2", 3/4", 1", thicker?
How many square feet of wall would one bag worth of lime mix cover at that thickness?
I can buy small quantities of pigments
here. for lime, clay and milk paints.
