Sigrid:
 
A good general guide to basic conservation is:
 
J.M. Cronyn, _The Elemements_of Archaeological-Conservation_, Routledge,
London: 1990.  Refer to pp. 102-115 for stone.
 
You may also find this article useful:
 
Kotlik, P., P. Justa and J. Zelinger, "The application of epoxy resins for
the consolidation of porous stone." in _Studies in Conservation_, 28:75:79.
 
Hope this gets you started in the right direction. As for Limestone
treatment, etc. I suggest you contact the physical plant at Indiana
University, Bloomington (check their website for a contact point). Almost
every building on the campus is made of carved Limestone from nearby
Bedford, Indiana, the "Limestone Capital of the World." I'd bet they have
some pretty extensive experience.
