1.0 INTRODUCTION

1.1 PURPOSE 1.1.1 The purpose of this procedure is to establish the methods by which the prime and finish coats are to be applied to the con-tainment liners and radiation areas in accordance with speci-fication, drawing, and manufacturer's requirements. This pro-cedure may also be used for coating any steel substrate inside the reactor buildings scheduled to receive Carbo Zinc 11 primer  ;

and Phenoline 305 finish coat.

8 1.2 SCOPE 1

1.2.1 The scope of this procedure covers the surface preparation and coating of Unit 1 and 2 steel substrates inside the reactor buildings and radiation areas scheduled to receive protective I coatings.

1.3 GENIRAL DISCUSSION 1.3.1 All coating materials covered by this procedure shall be as manu- ,

factured by Carboline _ Corporation of St. Louis, Missouri. The coating shall consist of a prime coat of Carbo Zinc 11 with a finish coat of Phenoline 305. To protect the prime ccat frem prolenged ex-posure, a " seal coat" consisting of approximately one mil. of Pheno-line 305, thinned in accordance with Section 4.4.2.4, may be applied over the prime coat. Prior to finish coating, the seal coat shall be solvent wiped with Phenoline thinner or Xylol. Finish coating snall be applied when convenient prior to completion of the building or prior to placement of concrete, equipment, or obstructions which would make finish coating impossible.

In order to maintain traceability on protective coatings applied to shop coated steel cited for installation in the Reactor Building, these items shall be steel stamped with a unique coating

- code number. The code numbers shall be assigned by QC Paint and applied by craft personnel. Upon division of materials, this unique number will be transferred along with all other unique identifying numbers.

If results are acceptable, Work may proceed in accordance with sections 4.4.2.2 through 4.4.2.9.

3.7.2 The QC Inspector or his representative shall notify the res-pensible area eqineer and/or the Paint Superintendent as soon as possible after ra tipt of a nonconforming item in need of paint repair to allow time for Attachment 2 preparation and a planned schedule for repair.

4.0 PROCEDURE FOR COATING 4.1 PREPARATION OF SUBSTRATES AND C0ATING MATERIALS 4.1.1 Surface Preparation for Primer - Final surface preparation shall not begin unless ghe temperature of the surface to be blasted and/or power tooled is 5 F above the dew point. If needed, the surface to be primed shall then be cleaned of any heavy oil or grease deposits in accordance with SSPC-SP-1-63 " Solvent Cleaning".

Small amounts of grease or oil deposits may be removed by blast 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 J:acky paint. Suffi-cient time shall be provided to allow suspended particles to

. settle before beginning primer application. If rust forms after l surface preparation, the rusted area shall be re-cleaned before primer application. Under no case shall a blast, hand, or power.

tool 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

b. Blast, hand or power tool cleaning using border tape - Clean the steel to near white metal approximately 3" - 6" beyond the point which will receive primer. Place border tape approximately 1" in from edge of cleaned area and prime.

When applying seal or finish coat on either of above methods hold back approximately 12" - 18" from edge of primer.

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 SSPC-SP-3. If it is determined that surface defects are severe enough to require later repair, the area to be repaired will be blocked out and spot painted at a later date. All protrusions and peaks shall be ground to a rounded contour.

4.1.3 If coating removal is required from an area or item which has pre-viously been coated in accordance with this procedure, stad0ws or tight residue of primer which may remain in tne profile of tne pre-viously prepared substrate is acceptable.

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 the use of a manufacturer recommended cleanser or cleansing method on areas that have been seal-coated. On areas where the Carbo Zinc 11 primer is exoosed, 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 require-ments are obtained.

4.2.2 The ambient temoerature and relative humidity shall be measured to

  • determine the dew point temperature. Phenoline 305 finisn0 coat snall be applied unless the substrate temperature is more than 5 F above the dew point.

4.3 PREPARATION OF C0ATING MATERIALS 4.3.1 Primer - The primer, Carbo Zinc 11, is packaged in a two component kit consisting of a base and zinc fil'.ar. First the base shall be thoroughly mixed. Zinc filler shall then be added under constant agitation and mixed until free of lumps. Partial mixes shall be mixed by weight in a proportion of 10 parts base to 22 parts zinc filler using a suitable scale to achieve a plus or minus 2 percent ac:uracy.

The mixture shall then be strained through a 30-mesh screen. Viscosity shall be controlled b'y adding thinner, as recuired, but shall not excee:

two quarts of thinner par gallon of Carbo Zinc 11. Fot life of CZ 11 shall be as shown in Attachment 4.

4.4 APPL.ICATION OF PRIME AND FINISH C0ATING 4.4.1 Prime Coat 4.4.1.1 Coating material shall be applied using conventional s:: ray ecuip-ment with agitated pressure pots having a maximum hose lengtn of l 75 feet. Care must be taken to assure that air and material pressures are adjusted to compensate the additional lengtn of hose from 50' to 75' in length. The primer shall be allowed to become tack free before start of other construction ocerations wnicn could create contamination problems. Any runs or sags having a detrimental effect on the coating system shall be removed and re-paired. The following application parameters shall also be followed:

1. Normaj conditions of 0ambient and surface temperature shall 0

be 40 - g5 F and 40 - 1100F_ respectively;0however, primer may be applied within an ambient rJnge of 0 - 130 0F and a sur- '

face temparature range of G - 200"F. Carbo-Zinc 11 may be thinned up to 2 quarts per gallon for application; however, when using higher thinning levels at or below normal tem-perature-range, care must be taken to obtain proper film build. Above 850F it is advisable to use up to 2 cuarts per gallon to minimize dry spray. In ro case _shall carbo-line limits be exceeded.

'2. Humidity values vary from 10 to g5: however, coating shall not be applied to a wet or damp surface.

3. Thickness of prime coat shall have a minimuc, d y film thickness of 2 mils and a maximum-of 4.5 mils. Minimum and maximum spot test values shall be 1.5 and 5.5 mils respective's.
4. A double regulated pot having an adequate air volume supply i shall be used.

_l S. As a guide, coating material may be applied using a 50% over-lap with each pass while holding a gun 8-10 inches from the surface. Cross hatch application is permissible. '

6. Carbo Zinc 11 is sufficiently curec for topcca; wnen cne coating may be burnished rather than removed when rubbed with the flat portion of a smooth edged coin such as a nickle. (Minor amounts of zinc dust may be removed during cure verification, however, a burnished surface must be achieved). Attachment 3 may be utilized as general guide-lines for cure to topcoat time of CZ-11 above 25% relative humidity. If required, the cure of carbo zinc II may be accelerated by the use of water spray, however, a minimum of one hour must elapse between application of coating and water spray. Selow 25% relative humidity, water curing is recommended to obtain the desired cure. Water utilized in conjunction with water curing shall have a PH factor from 5 to 9. Application of water spray for curing purposes may-be as often as necessary to obtain the proper cure.

4.4.1.2 Recoating of Carbo Zinc 11 Primer - Prior to recoating, if no major defects per section 4.4.2.9 are present, the entire primed surface to be recoated shall be wiped with clean rags moistened with Carboline Thinner #33. Wiping shall continue until em appreciable discoloration is noticed on the rags. Carbo Zinc 11 shall then be tainned by using two quarts Carboline NO. 33 per -

gallon mix. This will be applied to achieve a 2.0 - 4c5 mils total DFT. Only two recoats may be applied. Special attention should be given to spray application and dry. film thickness when using a 50% mix. The primed surface shall not be recoated until cured per section 4.4.1.1.6.

4.4.1.3 Repair of Sags and Runs - Sags or runs in excess of 5.5 mils will be adraded with an aluminum screen or sandpaper to 2.0 to 5.5 mils. Sags or runs 5.5 mils or less which show no evidence of mud-cracking will not be repaired. If coating surface is satis-factory after abrading, then finish coat may be applied; however, if coating surface is unsatisfactory, blast, hand abrade or power tool grind to near white metal is required and primer coat re-applied.

A satisfactory coating is considered one having no mud-cracking to the metal surface as visible to the unaided eye.

4.4.1.4 Brush touch-up painting shall be done on the prime coat in accor-dance with the following:

Prime Coat:

1. Carboline Application Instruction (Carbo Zinc 11) ,

Bulletin - October 76-N.

2. Carboline Product Data Sheet (Carbo Zinc 11)

4.4.1.7 Coating Interface - Refer to Section 4.4.3.0 for coating interfacing.

4.4.2 Finish Coat l

4.4.2.1 Finish coating shall be applied using conventional, airless,

  • brush or roller. Weld seams, edges and other sharp geometrical discontinuities may receive an initial coat of 1-2 mils finish I coating thinned by using two quarts Phenoline Thinner per each gallon kit of Phenoline 305. To aid in continuity at edges, edges may be

" striped" with Phenoline unthinned instead of the 50% mixture as stated above. In either " striping" or initial coating of edges, welds, etc., time should be allotted for the coating to harden sufficiently to maintain a "sealir.g" effect prior to continuing coating operations. The initial coating of edges, striping, etc., as stated above, shall be considered part of the total initial finish coating operation. The material shall be allowed  !'

to become tack free before any other construction operations proceed which could create contamination problems by dust .or other foreign matter. A continuity check shall be performed in i accordance with NACE T-6F-3 Condition "C". No gross discontinuities are acceptable such as holidays, voids, skips, bubbles, and misses.

Any runs or sags having a detrimental effect on the coating system shall be removed and repaired. The following application parameters shall govern:

1. The permissible range of surface and ambient temperature for application shall be 500 - 120 F. Temperature may rise above 1200 F after material has become " tack free". Phenoline 305 may be thinned up to 2 quarts of Phenoline Thinner per gallon mix.

Coatings shall be applied to the contair. ment liners and radiation areas in accordance with specification, drawing, and manufacturer's requirements. This procedure may also be used for coating any steel substrate inside the reactor buildings scheduled to receive primer or Dimetcote 6 and Phenoline 305 finish coat manufactured by Ameron and Cartoline respectively.

1.2 SCOPE 1.2.1 The scoce of this procedure covers the surface preparation and coating of Uni I and 2 steel suostrates inside the reactor buildings and radiation areas scheduled to receive protective coatings. ,

1.3 GENERAL DISCUSSION .

1.3.1 All coating materials covered by this procedure sFall be as manufactured by Carboline Corporation of St. Louir. Missourt or Amer 0n Protective Coatings Division, Brea, California. T.S e coating system will consist of a prime coat of Dimetcote 6 by Ameron with a finish coat of Phenoline 305 by Carboline. In order to protect the prime coat from prolonged exposure, a seal coat consisting of approximately one mil of Phenoline 305, thinned in accordance with Section 4.4.2.4, may be applied over the prime coat. Surface preparation of the seal coat prior to finish coating, shall consist of solvent wiping if exposed longer than 30 days.

Finish coating shall be applied when convenient prior to completion of the building --- or, prior to placement of concrete, equipment, or obstructions which would make finish coating impossible.

In order to maintain traceability on protective coatings appif ed to shop coated steel cited for installation in the Reactor Building, these items shall be steel stamped with a unique coating code number. The codt number shall be assigned by QC Paint and applied by craf t ' personne' . Upon division of materials, this unique number will be transferred along with all other unique identifying numbers.

4.0 PROCEDURE FOR COATING 4.1 PREPARATION OF SUBSTRATES AND COATING MATERIALS Surface Precarativr, f:r Prisuer - Final surface preparation shall not begin unless the temperature of the surface to be blasted and/or power tooled is 5"F above the dew point. If needed, the surface to be primed shall then be cleaned of any heavy oil or grease deposits in accordance with SSPC-SP-1-63 " Solvent Cleaning".

Small amounts of grease or oil deposits may be removed by blast operations. The surface shall .then be cleaned by blast, hand or power tool operations to ach,ieve an equivalent of SSPC-SP10-63,

, "near white" blast cleaning. Although 1-3 mil sur# ace 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 co'ntaminants from the surface. Air blasting shall not be performed where air-borne contaminants could adhere to tacky paint. Suffi-cient time shall be provided to allow suspended particles to .

settle befcre beginning primer application.' If rust forms af ter surface preparation, the rusted area sha11 be re-cleaneo before primer application. Under no case shall a blast, hand, or power tool 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 without additional cleaning of the surface.

b. Blast, hand or power tool cleaning using border tape - Clean the steel to near white metal-approximately 3" - 6" beyond the point which will receive primer. Place border tape approximately 1" in .

from edge of cleaned area and prime. When applying seal or finish coat on either of above methods hold back approximately 12" - 18" from edge of primer. '

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 i and SSPC-SP-3. If it is determined that surf ace defects are severe enough i to require later repair, the area to be repaired will be blocked out and (

spot painted at a later date. All protrusions and peaks shall be ground to a rounded contour.

4.1.3 If coating removal is required from an area or ite: which has previously been coated in accordance with this procedure, shadows or tight residue of primer which may remain in the profile of the previously prepared sub-strate is acceptable. However, areas with residues of Carboline 191 Primer shall be recoated with Carboline 191 Primer. Areas with residues of inorganic zine may be coated with either inorganic zine or Carboline .

191 Primer. It is not required that such areas meet the criteria of I SSPC-SP10 or SSPC-SP6.

4.2 SURFACE PREPARATION FOR FINISH COAT i

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 the use of a '

manufacturer recommended cleanser or cleansing method on areas that have i been seal-coated. On areas where the Carbo Zine 11 primer is exposed, oil and grease will be removed by sand blasting, hand, or power tool grinding, i and needle scaling and then by solvent wiping the area prier to replaceing !

the primer. Power tool grinding and needle scaling should yield surface -

cleanliness equal to that of SSPC-SP-10 "near white" blast cleaning. Power I tooled areas should be kept to a minimum however no size limitation is imposed providing acceptable surface cleanliness is achieved.

4.2.2 The ambient temperature and relative humidity shall be measured to determin the dew point temperature. Phenoline 305 finish shall not be applied  !

unless the substrate temperature is 5'F or more abovT*the dew point.
