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-ponsible area engineer and/or the Paint Superintendent as soon as possible af ter receipt of a nonconforming item in need of paint repair to allow time for Attachment 2 preparation and a planned schedule for repair.

4.0 PROCE3URE FOR COATING 4.1 PREPARATION OF SUBSTRATES AND COATING 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 poner tooled is S F above the dew point. If needed, the surface to I be primed shall then be cleaned of any heavy oil or grease deposits in acccrdance 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 13 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 surf ace. Air blasting shall rot be performed wnere air-borr.e contaminants could adhere to . tacky paint. Suffi-cient time shall be provided to allow suspended particles to settle before beginning primer application. If rust forms after 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 priming without additional cleaning of the surface. When applying coatings that will be joined together by a later coating operation, the interface shall be constructed as follows:

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, shadows or tight residue of primer which may remain in the profile of the 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 renoval, if needed, of any oil or grease. This shall be accomplished by tha 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 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 require-ments are obtained.

4.2.2 The ambient temperature and relative humidity shall be neasured to determine the dew point temperature. Phenoline 305 finisho ccat shall 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 crimer, Carbo Zinc 11, is packaged in a two component kit consisting of a base and zine fille *, 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 zine filler ut,ing a suitable scale to achieve a plus or minus 2 percent accuracy.

The mixture shall then be strained through a 30-mern screen. Viscosity shall be controlled by adding thinner, as required, but shall not exceet two quarts of thinner per gallon of Carbo Zinc 11. Pot life of CZ 11 shall be as shown in Attachnent 4.

Mixes are made by combining and thoroughly mixing the base and catalyst. Partial mixes may be made by combining, in a ratio by volume, four parts base to one part catalyst. Viscosity shall be controlled by adding thinner, as required, but shall not exceed two quarts of thinner per gallon of Phenoline 305. Pot life t.f Phenoline 305 shall be shown on Attachment 4 4.4 APPLICATION OF PRIME AND FINISH C0ATING 4.4.1 Prime Coat 4.4.1.1 Coating material shall be applied using conventional spray equip-ment with agitated pressure pots having a maximum hose length of 75 feet. Care must be taken to assure that air and material pressures are adjusted to compensate the additional length of hose from 50' to 75' in length. The primer shall be allowed to become tack free before start of other construction operations which could create contamination problems. Any runs or sags having a detrimental ef fect on the coating system shall be removed and re-paired. The following application parameters shall also be followed:

1. Normaj conditions of t.mbient and surface temperature shall be 40 - 95 0F and 400 0 however, primer may be applied within an amkient range of 0 - 130 0F and a sur-

- 110 F respectively;0 face temparature range of 0" - 200"F. Carbo-Zine 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 bu ild . Above 850F it is advisable to use up to 2 quarts per gallon to minimize dry spray. In no case shall carbo-line limits be exceeded.

2. Humidity values var / from 10 to 95t however, coating shall not be applied to a wet or damp surface.
3. Thickness of prime coat shall have a minimum dry 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 respectively.

4 A double regulated pot having tn adequate air volume supply shall be used.

5. As a guide, coating material may be applied using a 50t over-lap with each pass while holding a gun 810 inches from the surface. Cross hatch application is permissible.

6. Carbo Zinc 11 is sufficiently cured for topcoat when tne coating may be burnished rather than removed when rubbed with the flat portion of a smooth edged coin such as a nickl e. (Minor amounts of zine dust may be removed during cure verification, however, a burnished surface must be achieved). Attachment 3 may be utilized as general guide-lines fcr cure to topcoat time of CZ-11 above 25% relative humidity. If required, the cure of carbo zinc !! may be accelerated by the use of water spray, however, a minimum of one hour must elapse between application of coating and water spray. Below 25% relative humidity, water cering is recomr inded to obtain the desired cure. Water utilized in conjunction with water curing sh'all 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 Reccating of Carbo Zinc 11 Priner - 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 no appreciable discoloration is noticed on the rags. Carbo Zinc 11 shall then be thinned by using two quarts Carboline NO. 33 per gallon mix. This will be applied to achieve a 2.0 - 4.5 mils total DFT. Only two recoats may be applied. Special attention should be given to spray application and dry film thickness when using a 50t 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 m*'. Al 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:

4.4.1.6 Treatment of Rust Stains - Remove residue, though not neces-sarily the stain, with bristle brush and water or Carboline Thinner #33. Allow to dry thoroughly.

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

4.4.2 Finish Coat 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 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 507, 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 " sealing" 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 contaminat ton problems by dust or other foreign matter. A continuity check shall be performed in accordance with NACE T-6F-3 Condition "C". No gross discontinuities are acceptable such as holidays, volds, skips, bubbles, and misses.

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

1. The permissible range of surface and anbient temperature for application'shall be 500 - 1200F, Temperature may rise above 1200 F af ter material has become " tack free". Phenoline 305 may be thinned up to 2 quarts of Phenoline Thinner per gallon mix. The ratio of thinner to Phenoline will be that which gives i the best workable mix, i.e., usually advantageous to use more thinner at lower tenperatures.
2. Minimum and maximum values of relative humidity shall be 07, and 85% respectively.
3. As a guide, coating material shall be applied using a 50% over-lap w'th each pass while holding the gun 810 inches from the surface.

i 4.4.2.2 Repair of Runs and Sags - Runs and sags will be abraded until the

DFT of the Phenoline 305 is within 1.9 - 4.5 mils. If cracks i are visible, then runs and sags will be removed to primer by .

power tool grinding followed by solvent wiping. If no cracking occurs, top coat will be considered acceptable. Area will be recoated as outlined in the Repair of Pinholes and Discontinuities l (Section 4.4.2.4).

4.4. 2. 3 Repair of Embedded Foreign Particles - Foreign particles shall be removed by abrading and then recoated as outlined in the repair of pinholes and discontinuities. Reccating shall not be performed until cure times stated in Section 4.4.2.1(4) have been satisfied, a

i 4.4.2.4 Repair of Pinholes and Discontinuities - Loose particles shall be removed by brushing or vacuum r compressed air. The affected area shall be solvent wiped with Phenoline 305 Thinner or xylol. ,

Pinholes and small discontinuities may be repaired at the time of '

final inspection without a later reinspection of the repair. If the repair area requires recoating, recoat the area with Phenoline 305 thinned 50%. Recoated areas require cure to final inspection time per section 4.5.1.

4.4.2.5 Repair of Scratches and Damaged Areas - Any scratches or damaged

areas will be abraded until loosely adherent particles are re-moved. The area shall then be solvent wiped (Carboline thinner
  1. 33 for primer, Carboline Phenoline thinner or xylol for topcoat) '

and repaired with appropriate coating, i.e., Phenoline 305 if i l

) damage is considered a minor defect per section 4.4.2.8 and Carbo .

l Zine 11 and Phenoline 305 if damaged area is considered a major i defect per section 4.4.2.9. All edges of existing coating around I the perimeter of the cleaned area shall be " feathered" back a sufficient distance et ensure a smooth blend with existing coating.
