Gateway Park Center PERKINS+WILL <br /> 810495.000 <br /> 12/06/18 <br /> <br /> <br />HIGH-PERFORMANCE COATINGS <br /> 09 96 00 - 5 <br /> <br /> <br />E. Shop-Primed Steel Substrates: Clean field welds, bolted connections, and areas <br />where shop paint is abraded. Paint exposed areas with the same material as used <br />for shop priming to comply with SSPC-PA 1 for touching up shop-primed surfaces. <br />F. Galvanized-Metal Substrates: Remove grease and oil residue from galvanized sheet <br />metal by mechanical methods to produce clean, lightly etched surfaces that <br />promote adhesion of subsequently applied coatings. <br />3.3 APPLICATION <br />A. Apply high-performance coatings according to manufacturer's written instructions <br />and recommendations in "MPI Architectural Painting Specification Manual." <br />1. Use applicators and techniques suited for coating and substrate indicated. <br />2. Coat surfaces behind movable equipment and furniture same as similar <br />exposed surfaces. Before final installation, coat surfaces behind permanently <br />fixed equipment or furniture with prime coat only. <br />3. Coat backsides of access panels, removable or hinged covers, and similar <br />hinged items to match exposed surfaces. <br />4. Do not apply coatings over labels of independent testing agencies or <br />equipment name, identification, performance rating, or nomenclature plates. <br />B. Tint each undercoat a lighter shade to facilitate identification of each coat if <br />multiple coats of the same material are to be applied. Tint undercoats to match <br />color of finish coat, but provide sufficient difference in shade of undercoats to <br />distinguish each separate coat. <br />C. If undercoats or other conditions show through final coat, apply additional coats <br />until cured film has a uniform coating finish, color, and appearance. <br />D. Apply coatings to produce surface films without cloudiness, spotting, holidays, laps, <br />brush marks, runs, sags, ropiness, or other surface imperfections. Produce sharp <br />glass lines and color breaks. <br />3.4 FIELD QUALITY CONTROL <br />A. Dry Film Thickness Testing: Owner may engage the services of a qualified testing <br />and inspecting agency to inspect and test coatings for dry film thickness. <br />1. Contractor shall touch up and restore coated surfaces damaged by testing. <br />2. If test results show that dry film thickness of applied coating does not comply <br />with coating manufacturer's written recommendations, Contractor shall pay <br />for testing and apply additional coats as needed to provide dry film thickness <br />that complies with coating manufacturer's written recommendations. <br />3.5 CLEANING AND PROTECTION <br />A. At end of each workday, remove rubbish, empty cans, rags, and other discarded <br />materials from Project site.
