Provide barrier coats over incompatible primers or remove and re-prime as required. Notify Architect in writing of any anticipated problems using specified coating systems with substrates primed by others MATERIAL QUALITY A. Provide best quality grade of various types of coatings as regularly manufactured HIGH PERFORMANCE COATINGS

20 PART 3 - EXECUTION by acceptable paint materials manufacturer. Materials not displaying manufacturer s identification as a standard, best grade product will not be acceptable. 1. Proprietary names used to designate colors or materials are for the intended purpose of establishing a minimum standard of quality. 2. Provide undercoat paint produced by same manufacturer as finish coats. Use only thinners approved by paint manufacturer, and use only within recommended limits. B. Acceptable Manufacturers: 1. Tnemec Company, Inc., Kansas City, MO, ( ) 2. Architect-approved equivalent INSPECTION A. Applicator must examine areas and conditions under which painting work is to be applied, and notify Contractor in writing of any conditions detrimental to proper and timely completion of work. Do not proceed with work until unsatisfactory conditions have been corrected in a manner acceptable to Applicator. B. Starting of painting work will be construed as Applicator s acceptance of surfaces and other conditions within any particular area. C. Do not paint over dirt, rust, scale, grease, moisture, scuffed surfaces or conditions otherwise detrimental to formation of a durable paint film SURFACE PREPARATION A. General 1. Perform preparation and cleaning procedures in accordance with paint manufacturer s instructions and as herein specified for each particular substrate condition. a. Remove hardware, hardware accessories, machined surfaces, plates, lighting fixtures and similar items in place and not to be finish painted, or provide surface applied protection prior to surface preparation and painting operations. Remove, if necessary, for complete painting of items and adjacent surfaces. Following completion of painting of each space or area, reinstall removed items. b. Clean surfaces to be painted before applying paint or surface treatments. Remove oil and grease prior to mechanical cleaning. Program cleaning and painting so that contaminants from cleaning process will not fall onto wet, newly painted surfaces. c. Wash all existing surfaces with solution of trisodium phosphate or equal cleaner, followed by a wash with clear water. B. Cementitious Materials 1. Prepare cementitious surfaces of concrete and concrete block to be painted by removing efflorescence, chalk, dust, dirt, grease, oils and by roughening as required to remove glaze. 2. Determine alkalinity and moisture content of surfaces to be painted by performing appropriate tests. If surfaces are found to be sufficiently alkaline to cause blistering and burning of finish paint, correct this condition before application of paint. Do not paint over surfaces where HIGH PERFORMANCE COATINGS

21 moisture content exceeds that permitted in manufacturer s printed directions. 3. Clean concrete floor surfaces scheduled to be painted with a commercial solution of muriatic acid or other etching cleaner. Flush floor with clean water to neutralize acid, and allow to dry before painting. Follow manufacturer s preparation instructions for surfaces if different from above. C. Ferrous Metals 1. Clean ferrous surfaces which are not galvanized or shop coated of oil, grease, dirt, loose mill scale and other foreign substances by solvent or mechanical clean. a. Touch-up shop applied prime coats wherever damaged or bare, where required by other sections of these specifications. Clean and touch-up with same type shop primer. D. Galvanized Surfaces 1. Clean surfaces per ASTM D (2005) as a minimum. Follow manufacturer s written recommendations. Remove all passivators MATERIAL PREPARATION A. Mix and prepare painting materials in accordance with manufacturer s directions. B. Store materials not in actual use in tightly covered containers. Maintain containers used in storage, mixing and application of paint in a clean condition, free of foreign materials and residue. Maintain limited storage quantities as acceptable to the Fire Department. C. Stir materials before application to produce a mixture of uniform density, and stir as required during application. Do not stir surface film into material. Remove film, and if necessary, strain material before using APPLICATION A. General 1. Apply paint in accordance with manufacturer s directions. Use applicators and techniques best suited for substrate and type of material being applied. a. Apply additional coats when undercoats, stains or other conditions show through final coat of paint, until paint film is of uniform finish, color and appearance. Give special attention to ensure that surfaces, including edges, corners, crevices, weld and exposed fasteners receive a dry film thickness equivalent to that of flat surfaces. b. Paint surfaces behind movable equipment and furniture same as similar exposed surfaces. Paint surfaces behind permanently fixed equipment or furniture with prime coat only before final installation of equipment. c. Finish exterior doors on tops, bottoms and side edges same as exterior faces unless otherwise indicated. d. Sand lightly between each succeeding enamel coat. e. Omit first coat (primer) on metal surfaces which have been shop primed and touch-up painted unless otherwise indicated. HIGH PERFORMANCE COATINGS

22 B. Scheduling Painting 1. Apply first coat material to surfaces that have been cleaned, pretreated or otherwise prepared for painting as soon as practicable after preparation and before subsequent surface deterioration. a. Allow sufficient time between successive coatings to permit proper drying. Do not recoat until paint has dried to where it feels firm, does not deform or feel sticky under moderate thumb pressure, and application of another coat of paint does not cause lifting or loss of adhesion of the undercoat. C. Minimum Coating Thickness 1. Apply materials at not less than manufacturer s recommended spreading rate to establish a total dry film thickness as recommended by coating manufacturer. D. Mechanical and Electrical Work 1. Painting of mechanical and electrical work is limited to those items exposed in occupied spaces. E. Prime Coats 1. Apply prime coat of material which is required to be painted or finished, and which has not been prime coated by others. a. Recoat primed and sealed surfaces where there is evidence of suction spots or unsealed areas in first coat, to assure a finish coat with no burn-through or other defects due to insufficient sealing. F. Pigmented (Opaque) Finishes 1. Completely cover to provide an opaque, smooth surface of uniform finish, color, appearance and coverage. Cloudiness, spotting, holidays, laps, brush marks, runs, sags, ropiness or other surface imperfections will not be acceptable CLEAN-UP AND PROTECTION A. Clean-Up 1. During progress of work, remove from site discarded paint materials, rubbish, cans and rags at end of each work day. a. Upon completion of painting work, clean window glass and other paint spattered surfaces. Remove spattered paint by proper methods of washing and scraping, using care not to scratch or otherwise damage finished surfaces. B. Protection 1. Protect work of other trades, whether to be painted or not, against damage by painting and finishing work. Correct any damage by cleaning, repairing or replacing, and repainting as acceptable to Architect. a. At the completion of work of other trades, touch-up and restore all damaged or defaced painted surfaces FINISH PAINTING SCHEDULE A. The following finish systems refer to products of Tnemec Company, Inc., unless indicated otherwise. HIGH PERFORMANCE COATINGS
