Painted Finishes:

1. All exposed exterior aluminum: spray applied fiuorocarbon coating containing aminimum of 70% Kynar 500 Resin. Coating must meet the high performancerequirements of AAMA 605.2-1980. Color as selected by the Architect.

a. Coalings shall exceed performance requirements of AAMA 2605 and ASCA 96.b. The coatings application shall be done directly by an applicator. For visual

applicator shall use an Electrostatic Gun (4 head), not an Electrostatic Bell.c. The Architect and shall review visual control samples of production panels,

including clear prior to approval of final color.d. The shimmer and flop of mica flakes shall have a consistent color, appearance,

and directionality. A uniform orientation of finish shimmer shall be coordinatedwith final position of all panels on the building.

e. The Architect and Owner shall have final approval of each panel finish andinstallation orientation.

f. All finishing is to be performed after fabrication.

In the construction of visual mock-ups. finish the various components to show themaximum variation that wili exist in the actual building construction between adjacent andnon-adjacent components.

It is the intention of the specification.that the color variation between adjacent parts of thesame finish be imperceptible to the naked eye under normal daylight conditions. To thisend, the Contractor shali submit range samples defining the maximum variation of colorthat can be anticipated in the work. Samples shali be on lengths of extrusions not less than12" and on sheet I plate I panels nat less then 24" square. Pieces abutting or within 6" ofeach other in the construction shali not vary in color by more than the range so as thevariation to be Imperceptible to the naked eye under normal daylight conditions. Parts shalibe carefuliy inspected in the shop and graded for assembly compalibility and marked forinstaliation location.

Establish and submit for approval a quality control program to assure compliance with thespecified reqUirements. The program shali include documented procedures and processes.Contractor shali maintain complete certified inspection, testing and process records offinishing procedures. Said reconds shali be availabie to the Architect upon request. Nofinishing shali be performed prior to approval of this quality control program.

Each source of paint color shali be of sufficient to volume to be made in one batch for theentire project. This requirement shali apply to finished extrusions and panels as weli as toany painted glass lites.
