Paris Santa Fe-Fdsco Depot Rehabilitation © KEYSTONE ARCHITECTS <br /> July 10, 2001 <br /> <br />3.02 TESTING & ANALYSIS <br /> <br /> A. Analysis of existing plaster finishes has been conducted in order to identify the <br /> plaster type(s), primary ingredients and their proportions and method of <br /> formulation and application. The full results of this analysis are to be found in <br /> Appendix A. Contractor will allot adequate time and resources to field test <br /> proposed formula(s) and adjust formulas as necessary to achieve a good visual <br /> and functional match with historic plaster finishes.. This field testing and <br /> adjustment will require considerable trial and error and preparation of field <br /> samples and test patches. Contractor shall commit adequate time and resources <br /> to conduct this work at no additional cost to Owner. <br /> <br />3.03 SURFACE PREPARATION <br /> <br /> A. Demolition: Plaster demolition shall be limited to the removal of damaged, loose, <br /> deteriorated plaster and lath. Contractor shall make every effort to preserve <br /> existing sound areas of plaster. Identify such areas and notify Construction <br /> Manager to confirm that such areas shall be repaired through patching and <br /> matching rather than removal and replacement. <br /> <br /> B. Verify that substrate is clean and free of dirt and grit to insure maximum <br /> bonding between plaster and substrate. Areas to be patched should be cleaned of <br /> all debris with a bristle brush and all plant growth, dirt, oil or grease removed. <br /> <br />3.04 MATERIALS PREPARATION <br /> <br /> A. Field mix and prepare materials as required by custom plaster formula provided <br /> herein. <br /> <br /> B. Store materials not in actual use in tightly covered containers. Maintain <br /> containers used in storage, mixing and application of plaster in clean condition, <br /> free of foreign materials and residue. <br /> <br /> Section 09910 <br /> Page 4-7 <br /> <br /> <br />
