"repel water rather than absorb it"
"He also wrote about the procedure of cementing windows in situ and, through capillary action, the cement is able to regenerate itself when new oil or a thin mix of cement is introduced."

Aren't these contritictory statements? How can the plaster repel water and absorb oil? How does the plaster know what liquid is trying to get absorbed?
Geoff's concept on insitu rejuvenation of putty is predicted on adding the putty/slurry mix when the old putty starts to dry out before absorbed moisture can cause damage. And this is based on routine inspection and maintenance. In my experience, there is very little if any routine inspection and maintenance in this country. Maybe OZ is different.
