b. Contractor's equipment is constantly monitored to determine <br />operation will not contribute to any degradation of application (oil, <br />moisture, etc.) <br />C. Coating materials are inspected for compliance to specification and <br />all mixing/thinning operations are monitored.. <br />d. Surfaces are reinspected to verify no dust or other contaminants are <br />on surface and remedial cleaning performed as required. <br />e. After approval of surface, application is carefully monitored to verify <br />coatings are evenly applied at proper thickness and with no overspray <br />to interfere with adhesion'. <br />4. FINISH COAT(S) INSPECTION (INTERIOR) - After approval of prime <br />coat application, ongoing inspection monitors weather condition, Contractor's <br />application equipment and its operation, mixing of primer and physical <br />inspection of prime coat application, including spray techniques, cleanliness <br />of surface thickness, etc. <br />a. Procedures outlined in 3. above are repeated during application of <br />additional coatings, including careful examination of areas where <br />cleaning penetrated coating film to verify edges of film have not <br />lifted, curled, etc. Where defects exists, additional cleaning will be <br />performed to bring area into compliance with specification and area <br />will be recoated as required. <br />5. FINAL INSPECTION (INTERIOR) - Requires input at conclusion of finish <br />coatings to insure application, film continuity (holiday detection) and dry <br />film thickness are in complete conformance to specification. <br />a. DRY FILM THICKNESS TESTING: <br />(1) Prior to testing dry film thickness on any given day, Inspector <br />will calibrate his instrument against N.B.S. metal plate <br />standard. No plastic shims will be used. Instrument will be <br />re -calibrated at the beginning of the afternoon session or at <br />any time the instrument may have been subjected to impact <br />against scaffold, structure, etc. <br />(2) The coating is tested to determine it has sufficiently dried to <br />eliminate indentation of the probe into the coating, which <br />subtracts mils from the correct reading. If the coating does <br />3 <br />
