Carnegie Observatories - Hunt Building
Pasadena, L.A., California
Preservation of the Cast Stone Decorative Trim on this Myron Hunt Structure
The exterior cast stone trim on the historic headquarters of the Carnegie Observatories in Pasadena had been poorly treated during a previous rehabilitation. High-pressure water cleaning had scoured the original cement surface and left the cast stone more absorbent and prone to deterioration when exposed to moisture. Application of special rendering compounds stabilized these surfaces and made them much more resistant to weathering.
