Clarkt He are writing In regards to our inspection of the* * Portland City Hail. Bade with you on January 4. 1972. Our findings were that there was a notlcable aaount of Mono-Rote on the recessed areas of the East side of the building. Share were only occasional spots on the rest of the building. He also noted spots of other naterlals at various locations of the building. We suggest the use of a stiff brush to renove the Mono-Kote froa the building surface. We believe noat of this can be removed with a dry brush, but if needed it could be scrubbed with water. Zonollte Mono-Kote is coaposed primarily of Gypsun and Vemiculite, but does not contain Line.
