1.1 PURPOSE 1.1.1 The purpose of this procedure is to establish the methods by which  !

the surfacer and finish coats are to be applied to concrete sur faces in accordance with specification, drawing, and manufacturer's l req uireme nt s .

1.2 SCCPE 1.2.1 The scope of this procedure covers the surface preparation and coating of concrete surfaces inside the reactor building and l radiation area as delineated by Reference 1. j 1.3 GENERAL DISCUSSION l.3.1 All coating =ateria's addressed by this procedure shall he as manufactured by Imperial Pro fessional Coating of Skw Orleans, Lo uisia na . The coating system will consist of a surfacer of Nuter 1115, touch-up with Nutec #11 surfacer as required and a , .

- finish coat of Nutec #1201. j In areas where the concrete surface to be coar'd exhibits only minor amounts o f " bug holes" and sur face imper-Jections, Nutec silS surfacer cay be omitted with the use of Nutec #11 as the primary sur facer prior to topcoating with Nutec #1201. In order to prevent I finish coat damage , the finish coat will normally be applied as close  !

as possible to turn-over of the area to the owner or as required due to the. setting of equipment or other ite=s which would nake an area inacce ssible. Any persanent equipment located in the area to be coated will be adequately protected from conta=ination caused by surface preparation or coati =g application.

Where there is a conflict between this procedure and Re ference 1 the requirements of Re ference I shall prevail.

2.0 DEFINITIONS OF TERMS, ABEREVIATIONS AND SYMBOLS 2.1 TERMS 2.1.1 Substrate - The uncoated surface to which a coating is applied.

4.1 PREPARATION OF SUBSTRATES AND COATING MATERIALS 4.1.1 Preparation of Surfacer 4.1.1.1 Normal surface preparation shall consist of water blasting with 4,000 P.S.I. to 10,000 P.S.I. Additionally, surface prepara, tion may be accomplished by the use of approximately 2,500 P.S.I.

water blasting with sand injection, acid etching with an Imperial recommended solution, or. straight sand blasting. Any heavy oil or grease deposits shall be removed by steam cleaning, trisodium phosphate washing with a mixture of 3-6 pounds T.S.P. per gallon of water, or use of an Imperial reco== ended detergent.

Following surface preparation, the surface shall be free of o construction dust, laitance, and loose deposits. If cleaning does not remove oil and grease, the contaminated concrete surface will be chipped away and patched before coating. All T.S.P. cleaned areas will be flushed with clean water. Moles or voids in the concrete surfece that exceed 1/2" in dep-h shall be repaired with drypack or epoxy grout. Detrimental surface irreg-ularities such as ptojections, fins, or ridges shall be reduced by bus.. hammering, power grinding, or stoning. Wood particles of "fazz" remai,ing after water blasting is acchptable. Recommended turface preparation shall include power tools which are capable of removing liatance and curing membranes from concrete surfaces.

4.1.1.2 Markings on concrete: Defore application of IIS, 11 or 1201, all markings (ink, pen:1.1, chalk, or felt tip markers) on wall and floors shall be solvent wiped in accordance with SSPCSP1 using DL6A or commercially available MEK or Xylol. Marking paint (surveyor marks) shall be removed by solvent wiping, water blasting, sandblasting, or. power tool. cleaning. Discolored

/ coatings due to aging or stains shall be abraded and solvent wiped to remove the discoloration. Residual marking or dis-coloration remaining in pores below the plane of the surface.

is acceptable.

4.1.1.3 Repair of embedded foreign objects: Embedded foreign objects such as nails, rebar chairs and plastic endcaps ou rebar chairs, bolts.

3.2.3 Brush 3.2.3.1 A clean, high quality brush may be used to coat s=all areas or concrete inaccessible for spraying.

3.2.4 Roller 3.2.4.1 A short to cedium knap roller shall be used.

3.3 APPLICATION 3.3.1 Flush equipment with Imperial's 4DL-6A Universal Solvent or imperials #DL-56 (Cellosolve) Solvent prior to use.

3.3.2 Mixing instructions - slowly =ix by power agitation or by hand the entire volume of the cure component with the entire volune of the base. If an accelerator . is used, add thepre=easured portion to the base-cure mix and mix slowly. Avoid rapid agitation which may result in air entrapment. Do not vary proportions.

3.3.3 Thin t.he NUTEC #10 mix with 10-40: #DL-56 solvent (Cellosolve).

Thinning minimizes air entrapment, eliminates film irreglarities, enhances penetration,-a'nd prolongs the pot life of the material.

3.3.4 As a guide, if using conventional spray, regulate the air pressure:

60-80 psi to gun; 10-20 psi to pot.

NOTE: Required pressures may vary with temperature of hose length.

3.3.6 Apply NUTEC #10 at a spreading rate of approximately 350-400 sq. ft./ gal. kreid excessive build up which will cause a

" glazing" affect after drying.

3.3.7 NUTEC #10 has a pot life of approximately 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> (at 75'F). >

No material shall be applied which has exceeded its pot life.

If this has occured, there is an increase in the viscosity of the material, a noticeable heat of exothers and applied material will " crawl" and refuse to penetrate the concrete. All =aterial thus applied shall be removed frem the concrete with solvent and a clean cloth. All equipment shall be cleaned im=ediately and any remaining NUTEC 110 (expired) shall be discarded. Caution:

Storage of NUTEC #10 containers at high temperatures or in direct sunlight will greatly reduce its pot life.

NOTE: Po t life stated above for unthinned coating is the recommended time and should be used as a guideline for coating usage time, however, actual pot life may be longer. For unthinned coating or coating thinned less than 50%, the actual pot life is deter =ined by applicability of the coating.

3.3.3 During application all areas found to contain sags, surface

. irregularities, or excessive buildup of. NUTEC #10 shall be removed with solvent and a clean c19th and fresh NUTEC #10 applied.

3.3.9 Flush Spray equipment periodically with Imperial's DL6A Solvent or DL-56 to avoid build up of material in the hoses.

3.3.10 Clean up all equipment immediately following application with Imperial's #DL-56 cellosolve solvent or Imperial's !DL-6A Universal Solvent.

NOTE:

1. Do not apply NUTEC #10 curing compound to surfaces which vi.tble surface moisture or standing water is present.
2. Refer to manufactures product data sheet for general information.
3. Material may be applied at-temperatures above 80*F. When applications are made at temperatures above 80*F c.tre must be taken to assure pot life not exceeded.
