If needed, the turface to be primed U
shall then be cleaned of any heavy oil or grease deposits in S
accordance with SSPC-SP-1-63 " Solvent Cleaning".
Small amounts of grease or oil deposits may be removed by blast N
operations. The surface shall then be cleaned by blast, hand or power tool operations to achieve an equivalent of SSPC-SP10-63, "near white" blast cleaning. Although 1-3 mil. surface profile is preferred, a minimum of 1 mil. profile is required. After the above surface preparation, the surface to be primed shall be air blasted and/or solvent wiped to remove dust, sand or foreign contaminants from the surface. Air blasting shall not be performed where air-borne contaminants could adhere to tacky paint. Suffi-
\\f cient time shall be provided to allow suspended particles to 4

PROCEDURE FOR COATING 4.1 PREPARATION OF SUBSTRATES AND COATING MATERIALS 4.1.1 Surface Preparation for Primer - Under normal conditions, surface preparation shall got begin unless the temperature of the surface to be blasted is 5 F above the dew point.
If needed, the surface to be primed shall then be cleaned of any heavy oil or grease de-posits in accordance with SSPC-SPIO, "Near White Blast Cleaning",
hand, or power tool grinding and scaling to achieve 1-2 mil profile.
After sand blasting, hand or power tool grinding and scaling, the surface to be primed shall be air blasted and/or solvent wiped to remove all sand and foreign materials. This shall be done until the surface is clean and will not be performed where air-borne contaminants could adhere to tacky paint. Sufficient time shall
~
35-1195-CCP-30-A, October 17, 1979 REVISION O Page 7 of16 be provided to allow suspended particles to settle before beginning primer placement.
If rust forms after blast cleaning, the surface shall be " shower blast" cleaned before painting. Under no case will a blast cleaned surface be exposed for more than 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> prior to priming. When applying coatings that will be x
joined together by a 1. iter coating operation, the interface shall be constructed as follows: Overblast the steel to near white metal approximately 12" - 18" beyond the point which will receive primer.
Drop back approximately 12" - 18" on the primer when applying the seal-coat.
' 4.1. 2 Removal of Weld Spatter and Other Minor Surface Imperfections (NOT TO EXCEED.031" FOR CONTAINMENT LINERS) - If needed, weld spatter omitted by others will be removed by Painting Personnel-
. in accordance with SSPC-SP-2, and SP-3.
In areas where grinding and needle scaling is required, this will be witnessed by a
- Brown & Root QC Representative.
If it is determined that surface
' defects are severe enough to require later repair, then the area to be repaired will be blocked out and spot painted at a later date. All edges, protrusions, and peaks shall be ground smooth to a rounded contour; as a guide -1/8 inch radius of the contour "may be used.
4.2 SURFACE PREPARATION FOR FINISH COAT 4.2.1 Surface preparation for the finish coat shall consist of the removal, if needed of any oil or grease. This shall be accomplished by use of a manufacturer recommended cleanser or cleansing method on areas that have been seal-coated. On areas where the Dimetcote 6 primer is exposed, oil and grease will be removed by sand blasting, hand, or power tool grinding and needle scaling and then by solvent wiping the area prior to replacing the primer. Power tool grinding and needle scaling should be equivalent to a near white blast SP-10 specification with no size limitation as long as the millage requirements are obtained.
4.2.2 The ambient temperature and relative humidity should be measured to determine the dew point temperature. Phenoline 305 finish coat should not be applied unless the substrate temperature is more than 5a F above the dew point.

" paint distribution point" inside Reactor Uni t I.
A calibrated non-mercury filled dry bulb themometer or a calibrated tenperature recorder (Bristol 4069 TH or equivalent) shall be used for air temperature.detemination.
A calibrated non-mercury filled wet bulb themometer or a calibrated humidity recorder (Bristol 4069 TH or equivalent) shall be used to detennine relative humidity. The dew point shall be detemined by the difference in dry and wet bulb tenperature using the U.S. Department of Commerce Weather i
Bureau Psychrometric Tables, W.B. No. 235.
When dry bulb readings are greater than 100*F, the dew point and relative humidity should be detemined using the 100*F reading (note in Remarks Section).
The surface temperatu re shall be determined by placing a calibrated Range 0-250*F themometer or equivalent in contact with the surface to be coated. The thermometer probe shall remain in contact with the surface until the tenperature reading stabilizes.
Minimum and maximum values of surface and ambient temperatures shall be 50* F and 100*F respectively.
Infrequent dips in temperature to 40*F is pemissible during application and/or cure; howeve r, the elapsed time the temperature is below 50*F shall be added to the cure time.
Application of the coating shall not begin unless the surface teaperature is 5'F above the dew point.
Humidt ty may vary as high as 100%; however, free standing water shall be removed.
Coating application over a damp surface is pemissible. Under no conditions shall NUTEC 11S or Nutec 11 be applied to a surface containing free standing water. (Reference Attachment 6).
3.3.1.1 Documentation of Environmental Conditions a.
The Inspector assigned to the " paint di stribution point" in the Reactor Building shall, as a minimum, take a complete set of readings (air tenperature, relative humidity, dew point and surface temperature) on each floor elevation at least three (3) times each shift (preferably, the beginning, id point, and just prior to the end of each shift). More readings may be taken when necessary (i.e., noticeable change in air tenperature, request by field inspector to take readings in a specific area, etc.).

turn all of the Environmental Log Sheets for that shift into the lead inspector (s).
c.
The lead - inspector (s) shall review the log sheets for completeness and correctness, sign and da te the "QC Review" block, obtain copies for QC reference and transmit the originals to the Paper Flow Group.
-d.
If at any time the inspector determines readings which do not comply with the paraneters set forth in this procedure, he shall proceed in the following manner:
1 1.
Immediately take an additional set of readings in the immediate area of the first set of unacceptable readings and record them on the Envirormental Log.
2.
If the additional set of readings are acceptable, take a third set of readings for referee purposes dnd record them.
If the referee set of readings are acceptable, then tne area in question is acceptable but should be closely monitored with readings as necessary.
3.
If the additional set of readings is unacceptable and/or the referee set of readings is unacceptable, the inspector is to notify the coatings inspectors i
in the areas affected so that coating work may be stopped at that time.
Coating wo rk shall not continue until the ambient conditions resume an acceptable status.

A milky haze or mist in the finish of a recently applien coating.
Contaminant: _ A foreign substance, inadvertently added to a coating or found on the substrate that adversely affects the application, adhesion, curing and/or subsequent perfonnance of the applied coating.
Dry Soray:
A dry powdery primer or finish coat readily renoved by light sanding with either sandpaper or a wire screen.
A minor amount of adherent dry spray is acceptable on the final finish coat.
Feathering:
An area that is roughened and tapered to obtain a smooth '
and continuous surface with an existing damaged coating.
Fisheyes:
Small openings
(" fish eyes") in wet film exposing old surface or previous coat.
Free Standing Water: May be identified by:
a.
Reduced viscosity of the surfacer during application, and excessive sagging from bug holes.
b.
Wet rings around bug holes, c.
Visible signs of surface water.
d.
Running hand over the surface resulting in moisture on the hand.
e.
Product instability resulting in white streaks.
f.
Failure of the surfacer to adhere to the substrate during the sqeegeeing or troweling process.
l Full Hiding:
The coating provides sufficient coverage so that the preceding coat is not readily visible with an unaided eye.
l Holiday:
A pinhole, s ki p, discontinuity or void in coating film.
Laitance: A fine, whitish accumulation on concrete surfaces.
It con-sists mainly of cement particles that were carried by water rising to the surface of freshly placed concrete. The resulting concrete surface is unsuitable for proper adhesion or bond of subsequent fillers or protective coatings.
Monitor: Confonnance verification by physically observing a task being perfonned on a periodic or random basis.

PREPARATION OF COATING MATERIALS Surfacer Coat The surfacer, NUTEC 115, is packaged in a three camponent kit consisting of a base, curing agent, and filler.
The base and curing agent shall be thoroughly mixed first.
If necessary, box the mixture to assure that all the base and l
NJ
~'
cure has been used. The filler shall then be slowly added under constant agitation and mixed until a smooth blend is achieved. The patching material, NUTEC 11, is prepared the same way. Partial mixes for NUTEC 11S shall be in accordance with Attachment 7A. No provision is given for partial mixes of NUTEC 11.
Finish Coat l
The finish coat,.NUTEC 1201, is a two caponent epoxy topcoat consisting of a base and cure.
These shall be-thoroughly mixed under constant agitation until a homogenous blend is achieved.
Partial mixes of NUTEC 1201 shall be in accordance with Attachment 78.
Minimum induction times shall be as per Attachment 2.
SEALER / CURING COMPOUND i
The sealer / curing campound, NUTEC 10, i.s nomally a two component material consisting of a base and a curing agent.
If applying to surfaces below 60*
F, a third camponent accelerator may be used.
Slowly mix by power agitation or by hand the entire volume of the cure caponent with the entire volume of the 'Jase camponent.
If an accelerator is used, add the preseasured portion to the base-cure mixture and agitate slowly.
Avoid rapid agitation which may result in air entrapment. Thinning may be perfomed by adding fram i
10-40% by volume #DL-56 solvent.
Do not vary mixing proportions.
