David,

Here are a couple of references.  Whether you can actually get your hands on
them is another matter.  Let me know if you have problems.

"Durability of Building Materials and Components," proceedings of the Fifth
International Conference, Brighton, UK, 7-9 November 1990.

"Composite Stone Repairs at Drayton Hall: A Case Study of Stone Restoration
Techniques," ART XIV-3-82, pp. 37-41

"Rehabilitation Approaches to Severely Deteroirated Brown Sandstone at the
Apex Building, Washington, D.C.," ART XVII-3/4-85, p. 65-68

"Acrylic Polymers for the Conservation of Stone: Advantages and Drawbacks"
by Marisa Laurenzi Tabasso, ART XXVI-4-95, pp. 17-21

"Consolidation Treatment: Massillion (Ohio) Sandstone" (and Klaus J. H.
Zinsmeister, and Frances R. Gale), ART XX-3-88, pp. 35-39

Regards,
