1.0 INTRODUCTION

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 surfaces in accordance with specification, draw-ing, and manufacturer's requirements. .

1.2 SCOPE 1.2.1 The scope of this procedure covers the surface preparation and coating of cementitous surfaces inside the reactor build-ing and radiation area as delineated by Reference 1.

1.3 GENERAL DISCUSSION 1.3.1 All coating materials addressed by this procedure shall be as manufactured by Imperial Professional Coating of New Orleans, Louisiana. The coating system will consist of a surfacer coat of NUTEC #115, touch-up with NUTEC #115 or NUTEC #11,

, and a finish coat of Reactic #1201. In order to prevent finish i

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 items which would make an area inaccessible. Any permanent equipment located in the area to be coated will be adequately protected from contamination caused by surface preparation or coating application.

PROCEDURE EFFECTIVE BROWN & ROOT, INC. NUMBER REVISION DATE PAGE CPSES JOB 35-1195 CCP a0 4 5/11/82 5 of 13 Following surface preparation, the surface shall be free of 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. Holes or voids in the concrete surface that exceed 1/2" in depth shall be repaired with dry-pack or epoxy '

grout. Detrimental surface irregularities such as projections, fins, or ridges shall be reduced by bush-hamering, power grind-ing, or stoning. Wood particles of " fuzz" remaining after water blasting is acceptable. Recommended surface preparation shall include power tools which are capable of removing laitance and curing membranes from concrete surfaces.

4.1.1.2 Markings on concrete - Before application of 115,11 or 1201, all markings (ink, pencil, chalk, or felt tip markers) on wall and floors shall be solvent wiped in accordance with SSPC-SP-1 using-DL-6A or comercially available MEK or Xylol. Marking paint (surveyor marks) shall be completly removed by solvent wiping, water blasting, sandblasting, or power tool cleaning.

(

4.1.1.3 Repair of embedded foreign objects - Embedded foreign objects such as nails, rebar chairs, bolts, wood, or plastic shall be repaired per the following guidelines before application of NUTEC 115 sur-facer.

1. Objects protruding from the surface shall be ground or cut smooth until the object is flush with the concrete surface prior to application of 11S.
2. If the object is loosely adherad in the concrete, it shall be removed (in case of wood spiinters or wood " fuzz" an '

attempt shall be made to remove by high pressure water blast-ing). Refer to section 4.1.1.1.

3. . Smooth objects such as steel or plastic shall be roughened to provide adequate anchor pattern for the 115 surfacer. ' Metal objects shall be power tool cleaned to remove dust and mil scale and solvent wiped to remove any grease or oil.

1.2 SCOPE 1.2.1 The scope of this procedure covers the surface preparation and coating of cementitous surfaces inside the reactor build- l ing and radiation area as delineated by Reference 1.

1.3 GENERAL DISCUSSION 1.3.1 All coating materials addressed by this procedure shall be as manufactured by Imperial Professional Coating of New Orleans, Louisiana. The coating system will consist of a surfacer

  • coat of NUTEC #115, touch-up with NUTEC #115 or NUTEC #11.

and a finish coat of Reactic #1201. In order to orevent finish

. coat damage, the finis.h 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 items which would make an area inaccessible. Any permanent ecuipment locat'ed in the area to be coated will be adequately protected from contamination caused by surface preparation or coating application.

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

2.1.2 Pinhole - A minor discontinuity in the coating film which exposes l the primer or substrate.

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. Holes or voids in the concrete surface that exceed 1/2" in depth shall be repaired with dry-pack or epoxy grout. Detrimental surface irregularities such as projections, fins, or ridges shall be reduced by bush-hammering, power grind-ing, or stoning. Wood particles of "fucc" remaining af ter water blasting is acceptable. Recommended surface preparation shall include power tools which are capable of removing laitance and curing membranes from concrete surfaces.

4.1.1.2 Parkings on concrete - Before application of 115,11 or 1201, all markings (ink, pencil, chalk, or felt tip trarters) on wall and floors shall be solvent wiped in accordance with SSPC-SP-1 using DL-6A or commercially available MEK or Xylol. Marking paint (surveyor marks) shall be completly removed by solvent wiping, water blasting, sandblasting, or power tool cleaning.

1. INTRODUCTION 1.1 PURPOSE 1.1.1 The purpose of this procedure is to establish the methods e by which .the surfacer and finish coats are to be applied to concrete sufaces in accordance with specification, draw-ing, and manufacturer's requirenents.

1.2 SCOPE 1.2.1 The scope of this procedure covers the surface preparation and coating of concrete surfaces inside the reactor build-ings and radiation areas as delineated by Reference 1.

1.3 GENERAL DISCUSSION 1.3.1 All coating materials addressed by this procedure shall be as manufactured by Imperial Professional Coating of New Orleans, Louisiana. The coating system will consist of a surfacer coat of NUTEC # 115, touch-up with NUTEC # 115 or NUTEC # 11, and a finish coat of Reactic #1201. In order to prevent 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 items which would make an area inaccesible. Any permanent equipment located in the area to be coated will be adequately protected from contamination caused by surface preparation or coating application.

e

2. DEFINITION OF TERMS, ABBREVIATIONS AND SYMBOLS 2.1 TERMS 2.1.1 Substrate - The encoated surface to which a coating is applied.

2.1.2 Pinhole - A minor discontinuity in the coating film which ex- .

poses the primer or substrate.

1. INTRODUCTION 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 sufaces in accordance with specification, draw-ing, and manufacturer's requirements.

1.2 SCOPE 1.2.1 The scope of this procedure covers the surface preparation and coating of concrete surfaces inside the reactor build-ings and radiation areas as delineated by Reference 1.

1.3 GENERAL DISCUSSION 1.3.1 All coating materials addressed by this procedure shall be as manufactured by Southern Imperial Coatings of New Orleans, Louisiana. The coating system will consist of a surfacer coat of NUTEC # 115, touch-up with NUTEC # 115 or NUTEC # ll, and a finish coat of Reactic #1201. In order to prevent finish coat damage, the finish coat will normally be aoplied as close as possible to turn-over of the area to the owner or'as required due to the setting of equipment or other ita9s which would make an area inaccesible. Any permanent equipment located in the area to be coated will be adequately protected from contamination caused by surface preparation or coating application.

2. DEFINITION OF TERMS, ABBREVIATIONS AND SYMBOLS 2.1 TERMS 2.1.1 Substrate - The uncoated surface to which a coating is applied.

2.1.2 Pinhole - A minor discontinuity in the coating film which ex-pose the primer or substrate.

General receiving procedures shall be in accord-ance with Brown & Root Construction Procedure ACP-3. It shall then be segregated from "Non-Q" materials and stored in the Paint Storage Building where temperatures will be maintained between 400 F and 1000 F. Infrequent dips (up to 24 hrs.) in air temperature in storage areas as low as 330 F is acceptable; however, prior to application the coat-ings shall be brought back into the 500 - 900 F range. Tem-porary storage may be reouired at the Receiving Warehouse due to receiving or other problems.

3.5.2 Dispensing 3.5.2.1 When coating materials are needed in the field, they shall be transferred from the controlled storage area to tempor-ary storage in the field; due to limited shelf life, this shall be done on a "first-in", "first-out" basis. If dam-age occurs in transit from storage area, material will be consigned to "Non-Q" storage; damage shall mean a broken seal.

4. PROCEDURE FOR COATING 4.1 PREPARATION OF SUBSTRATES AND C0ATING MATERIALS 4.1.1 Preparation for Surfacer 4.1.1.1 Under normal conditions, surface preparation shall not be-gin unless the temperature of the surface to be prepared is SFO above the dew point. Normal surface preparation shall consist of water blasting with approximately 4000 P.S.I.

water held at 2-3 feet from the surface. Additionally, sur-face preparation may be accomplished by use of approximately 2500 P.S.I. water blasting with sand injection (held 2-3 feet), 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

35-1195-CCP-40, November 29, 1977 REVISION 1, January 25, 1978 PAGE 7 of 15 washing with a mixture of 3-6 pounds T.S.P. per gallon of water, or use of an Imperial recommended detergent.

Following surface preparation, the surface shall be free of construction dust, laitenance, 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. Detrimental surface irregularities such as projections, fins, or ridges shall be removed by bush-hammering, power grinding, or stoning. All tie holes and other holes greater than 2 inches in diameter will be filled with a sand cement " Dry-Pack". Holes 2 inches or less in diameter may be filled with #115 surfacer.

4.1.2 PREPARATION FOR FINISH COAT 4.1.2.1 Prior to beginning surface preparation for the finish coat.

- the surface temperature shall be at leastt 50 F above the dew point. It shall then consist of the removal of any .

oil or grease by use of trisodium phosphate washing, 3-6 pounds T.S.P. per gallon, or any other manufacturer rec-ommended cleanser or cleansing method. Construction dust I shall be removed by use of compressed air.

4.2 PREPARATION OF C0ATING MATERIALS 4.2.1 Surfacer Coat 4.2.1.1 The surfacer, NUTEC #115, is packaged in a three component kit consisting of a base, curing agent, and sand filler.

, The base and curing agent shall be thoroughly mixed first.

1. INTRODUCTION 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 sufaces in accordance with specification, draw-ing, and manufacturer's requirements.

1.2 SCOPE.

1.2.1 The scope of this procedare covers the surface preparation and coating of concrete surfaces inside the reactor build-ings and radiation areas as delineated by Reference l.

1.3 GENERAL DISCUSSION 1.3.1 All coating materials addressed by this procedure shall be as manufactured by Sodthern Imperial Coatings of New Orleans, Louisiana. The coating system will consist of a surfacer coat of NUTEC # 115, touch-up with NUTEC # 11S or NUTEC # 11,

, and a finish coat of Reactic #1201. In order to prevent 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 items which would make an area inaccesible. Any permanent eouipment located in the area to be coated will be adequately protected from contamination caused by surface preparation or coating application.

2. DEFINITION OF TERMS, ABBREVIATIONS AND SYMBOLS 2.1 TERMS 2.1.1 Substrate - The uncoated surface to which a coating is a pplied.

2.1.2 Pinhole - A minor discontinuity in the coating film which ex-pose the primer or substrate.

3. SPECIAL ITEMS AND OPERATIONS 3.1. QUALIFICATION OF PERSONNEL 3.1.1 Coating Application Personnel shall be cualified per pre- l vious experience and/or demonstrated ability. In addition, each applicator shall have been instructed by Southern Imoer-ial in the use of their products as consistent with Southern Imperial's Training Procedures. This shall be verified by completing a form similar to Attachment 2 which will be exe-cuted by the B&R Paint Superintendent or his representative.

. A coating manufacturer's representative will be_ available for technical supervision upon initial painting effort.

3.2 SAFETY REQUIREMENTS 3.2.1 All appropriate health, safety, and fire protection require-ments pertaining to surface preparation and coating appli-cation shall be followed. It shall be the responsibility of the Paint Superintendent to carry out actions as required by the Safety Department representative who will be present to monitor and enforce safety during coating application.

3.3 INSTRUMENTS AND THEIR USE 3.3.1 The Painting Foreman and General Foreman shall have access to and be familiar with the use of all instruments necessary '

to assure that proper application procedures are being fol-lowed. This shall include thermometers, wet film gauges, and a psychrometer for measuring relative humtdity. Viscos-ity measuring devices will not be used. Wet film gauges will be randomly used during coating application; readings will be limited to the mintmum necessary to control coating thickness.

3.4 DOCUMENTATION 3.4.1 Records shall be maintained on all attachments listed in Sectior 5.1 The. Superintendent in charge of painting, or his' representative, shall assure that all necessary forms are completed by the aporopriate personnel. After comple-tion, distribution copies shall be made and distributed to the parties as shown on the distribution section. The original will be forwarded to the Brown & Root Quality Control Department

35-1195-CCP-40, November 29, 1977 REVISION O PAGE 6 of 17 3.5 REC IVING, STORING AND DISPENSING OF COATING MATERIALS 3.5.1 Receiving and Storage 3.5.1 Upon receipt of a shipment of coating materials, the B&R QC Representative accepting shipment shall be responsible for completing all necessary receiving inspection documen-tation. General receiving procedures shall be in accord-ance with Brown & Poot Construction Procedure ACP-3. It shall then be segregated from "Non-Q" materials and stored in the Paint Storage guilding where temperatures will be maintained between 40 F and 1000 F. Infrequent dips (up to 24 hrs.) in air temperature in storage areas as low as 330 F is acceptable; however, prior to application the cnat-ings shall be brought back into the 500- 900 F range. Tem-porary storage may be required at the Receiving Warehouse due to receiving or other problems.

3.5.2 Dispensing 3.5.2.1 When coating materials are needed in the field, they shall be transferred from the controlled storage area to temoor-ary storage in the field; due to limited shelf life, this.

shall be done on a "first-in", "first-out" basis. If dam-age occurs in transit from storage area, material will be consigned to "Non-Q" storage; damage shall mean a broken seal. At the time of issuance, Attachnent I shall be used to verify the issuance of coating from an individual batch.

4. PROCEDURE FOR CO.A TING 4.1 PREPARATION OF Sl'BSTRATES AND C0ATING MATERIALS 4.1.1 Preparation for Surfacer

, 4.1.1.1 Under normal conditions, surface preparation shall not be-gin unless the temperature of the surface to be prepared is 5FO above the dew point. Normal surface preparation shall consist of water blasting with approximately 4000 P.S.I.

water held at 2-3 feet from the surface. Additionally, sur-face preparation may be accomplished by use of approximately 2500 P.S.I. water blasting with sand injection (held 2-3 feet), 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 i

35-1195-CCP-40, November 29, 1977 REVISION O PAGE 7 of 17 washing with a mixture of 3-6 pe;nds T.S.P. per gallon of water, or use of an Imperial recommended detergent.

Following surface preparation, the surface shall be free of construction dust, laitenance, 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. Detrimental surface irregularities such as projections, fins, or ridges shall be removed by bush-hammering, power grincing, or stoning. All tie holes and other holes greater than 2 inches in diameter will be filled with a sand cement " Dry-Pack". Holes 2 inches or less in diameter may be filled with #115 surfacer.

4.1.2 PREPARATION FOR FINISH C0AT 4.1.2.1 Prior to beginning surface preparation for the finish coat, the surface temperature shall be at least 50.F above the dew point. It shall then consist of the removal of any oil or grease by use of trisodium phosphate washing, 3-6 pounds T.S.P. per gallon, or any other manufacturer rec-ommended cleanser or cleansing method. Con
truction dust shall be removed' by use of compressed air.

4.2 PREPARATION OF COATING MATERIALS 4.2.1 Surfacer Coat 4.2.1.1 The surfacer, NUTEC #11S, is packaged in a three component kit consisting of a base, curing agent, and sand filler.

The base and curing agent shall be thoroughly mixed first.

If necessary, box the mixture to assure that all the base and cure has been used. The sand 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, i

4.1 PREPARATION OF SUBSTRATES AND COATING MATERIALS ,

I 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 preparation ,

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 recommended detergent.

Following surface preparation, the surface shall be free of 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. Holes or _:

voids in the concrete surface that exceed 1/2" in depth shall be repaired with drypack or epoxy grout. Detrimental surface irreg- _-

ularities such as projections, fins, or ridges shall be reduced . .

by bushhammering, power grinding, or stoning. Wood particles of

" fuzz" remaining after water blasting is acceptable. Recommended surf ace preparation shall include power tools which are capable of removing 11atance and curing membranes from concrete surfaces.

4.1.1.2 Markings on concrete Before application of 115, 11 or 1201, all markings (ink, pencil, 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 selvent wiped to remove the discoloration. Residual marking or dis-coloration remaining in pores below the plane of the surface is acceptable.
