] 7.2.2 Application Sequence
; 7.2.2.1 Sealing - For the best result s , a "Se aler" coat of No. 4129 is recounsended prior to l
application of Nos. 4000 or 6548-S. 7.2.2.2 Patching = Ilotes larger than 1/4 inch in diameter will probably require a separate patching i procedure, using ei6her a cement grout or an epony sur f acer approved for use in canjunction 3 with the specified coating system. l 7.2.2.3 Airless spray, brush or roller, using the equipment specified herein, is recomended to 1 initially apply Nos. 4000 and 654&-5. A squeegee, or other suitable tool, is used immsediately to smooth out the initial application. l 7.2.2.3.1 Apply the ministas amount of surf acer that is required to fill the holes and t
' voids and produce a 90% (appros.) pinhole free surface. It is not practical to spend an excessive amount of time to attain a 100% pinhole f ree surf ace during the first appl ic at ion . -
7.2.2.4 A second application of surf acer, at least TE WurTTater , as nor nab y required to produce a 1002 pinnole free surface. An average dry film thickness of 25 mits over the flat surface is recoaguended for the two combined applications. 7.2.2.5 It la necessary to produce a pinhule f ree surf ace prior to any applica: ton of finish coat. since the finish coat does not have the ability to fill pinholes. O 7.2.3 7.2.2.6 A enree man crew is recoersended for this application procedure; one to anly the material and tuo squeegee men. Other Application Metnods 7.2.3.1 Stoad Knife - A broad knife may be practical to use to patch or spot-fill holes to produce a pinnole free surf ace or to use instead nf a squeegee.

ATTACHMENT 2E M-7 Rev. 1 Sheet 8 o'f 9 I Coating Service Level One pertains to those coating systems, applied to structures, systems and components wnien are essential to the prevention of, or the mitigation of the consequences of postulated accidents that could cause undue risk to the health and safety of the public. Coating Service Level One areas include the primary containment and other safety related areas where failure of the paint or coating system could adversely affect the orderly shutdown of the reactor in response to DBA conditions. l STEEL SURFACES SURFACE PREPARATION - Carbon steel surfaces should be prepared in accordance with Steel Structures Painting Council specifications, using silica sand, gnt or steel shot and a profile of 1.5-3.0 mils, as follows:
