6.1.2 Surfaces shall be primed after cleaning before any rusting occurs. If rust forms after cleaning, the surface shall be re-cleaned before painting to the originally specified condition.

6.2 Solvent Cleaning (SSPC-SP 1)

6.2.1 Solvent cleaning consists of the removal of oil, grease and similar contaminants by cleaning with solvent, vapor, alkaline, emulsion, steam or detergent.

6.2.2 Prior to solvent cleaning, soil, cement spatter, salts or any other foreign matter other than oil or grease shall be removed by a seal fiber brush, wire brush of by scraping.

6.3 Pickling (SSPC-SP 8)

6.3.1 Pickling consists of completely removing all mill scale, rust and rust scale by chemical reaction, electrolysis or by both.

6.3.2 Prior to pickling, all heavy deposits of oil, grease, soil or other similar substance, except rust, mill scale or oxides, shall be removed by solvent cleaning, scraping or brushing.

6.4 Hand Tool Cleaning (SSPC-SP 2), Power Tool Cleaning (SSPC-SP 3) and Power Tool Cleaning to Bare Metal (SSPC-SP 11)

6.4.1 Hand tool cleaning consists of the removal of loose rust, mill scale and paint by hand chipping, scraping, sanding or wire brushing.


6.4.2 Power tool cleaning consists of the removal of loose rust, mill scale and paint by power tool chipping, sanding, wire brushing or grinding.

6.4.3 Power tool cleaning to bare metal consists of the removal of loose rust, mill scale and paint to produce a bare metal surface and to retain or produce a surface profile.

6.4.4 Prior to hand or power tool cleaning, oil grease and salts shall be removed by solvent cleaning. Exercise care in the use of tools to prevent excessive roughening of the surface and the formation of ridges and burrs. Excessive power wire brushing produces a burnished slick surface not suitable for coating.

6.4.5 Only power sanding shall be used when cleaning of zinc-rich primed surface is required prior to application of build coat and finish coat.

6.5 Blast Cleaning

6.5.1 Brush-Off Blast Cleaning (SSPC-SP 7) is a surface preparation where all oil, grease, dirt, rust scale, loose mill scale, loose rust and loose paint or coatings are removed completely. Tight mill scale and tightly-adhered rust, paint and coatings are permitted to remain if all mill scale and rust have been exposed to the abrasive blast pattern sufficiently to expose numerous flecks of the underlying metal uniformly distributed over the entire surface.

6.5.2 Commercial Blast Cleaning (SSPC-SP 6) is a surface preparation where at least 2/3 of each element of area is in the white metal condition. All oil, grease, dirt, rust scale and foreign matter shall be completely removed from the surface. All rust, mill scale and old paint shall be completely removed except for slight shadows, streaks or discolorations caused by rust stain, mill scale oxides or slight, tight residues of paint or coating that may remain. If the surface is pitted, slight residues of rust or paint may be found in the bottom of pits.

6.5.3 Near-White Blast Cleaning (SSPC-SP 10) is a surface preparation where at least 95 percent of each element of area is in the white metal condition. All oil, grease, dirt, mill scale, rust, corrosion products, oxides, paint or other foreign matter shall be completely removed from the surface except for very light shadows, very slight streaks or slight discolorations caused by rust stain, or mill scale oxides that may remain.

6.5.4 White Metal Blast Cleaning (SSPC-SP 5) is a surface preparation with a gray- white, uniform metallic color, slightly roughened to form a suitable anchor pattern for coatings. The surface, when viewed without magnification, shall be free of all oil, grease, dirt, visible mill scale, rust, corrosion products, oxides, paint or any other foreign matter.

6.5.5 Prior to blast cleaning, oil and similar matter shall be removed with a solvent wash (SSPC-SP 1). Mill varnish shall be completely removed with a solvent wash if white or near white abrasive blasting is not specified. Any chemical contamination shall be neutralized and/or flushed off prior to further surface


preparation.

6.5.6 Abrasives shall be composed of clean, dry, hard particles free of foreign substances such as dirt, oil, grease, toxic substances organic matter, mill scale and water soluble salts. The pH of the abrasive materials shall be 6.0 to 8.5. Prior to use, abrasives shall be tested for chloride content using the Bresle Method or other approved procedures. Maximum acceptable conductivity of the abrasives shall be 300 s/cm. Abrasives shall be sharp garnet or grit of Rockwell hardness 40 to 50 and properly graded. Abrasive particle size shall be suitable for producing an angular, sharp anchor profile. Shot is not acceptable. Silica or other abrasives containing more that 1% crystalline silica shall not be used. Refer to NIOSH Publication No. 92-102.

6.5.7 Abrasive blasted surfaces shall be tested for soluble salt contamination using the Bresle Method, KTA Scat Kit, Chlor*Test Kit or other approved method prior to application of the coating system primer. Maximum acceptable chloride levels shall be 30 m/cm2.

6.5.8 Steel surfaces shall not be blasted when surface temperature is less than 5F above the dew point, relative humidity is greater than 90 percent or there is a possibility that the blasted surface will be subject to wetting before the first coat of primer can be applied. Surfaces shall be blown, wiped or vacuumed free of blasting abrasive and dust before they are primed.

6.5.9 All structures and equipment shall be designed and manufactured respecting the specifications as defined in EN ISO 12944 Part 3 to obtain high performance painting systems, in particular:

All corners of steel structures shall be rounded-off with a radius of 1/8 or greater There shall be no interstices and no inaccessible areas There shall be no rainwater retention areas Weld spatter and remains of temporary welds, deposits, weld flux, slag or other

surface defects shall be removed by appropriate means; removal by deep grinding is subject to the approval of the Owner Representative.

For new construction, the surface preparation shall be carried out before assembling bolted assemblies; for maintenance work, bolted assemblies shall always be dismantled

All oil or grease shall be removed by washing with solvents or any other suitable means before the start of surface treatment operations.

The Contractor shall protect all equipment that is not to be painted or liable to be affected by the presence of abrasives or paint. Special attention shall be given to avoid overspray of zinc coatings on surfaces made of austenitic stainless steels to prevent high temperature cracking corrosion.

6.5.10 Welded areas shall be given special attention for removal of rough or sharp edges, weld flux, slag, weld metal spatter, weld heat oxides, laminations, slivers and other foreign objects before blasting.


6.5.11 Since freshly blasted surfaces are subject to immediate corrosion, particularly in areas of high humidity or salt atmosphere, no more surface shall be blast cleaned than can be primed before visible or detrimental re-rusting occurs. A prime coat shall be applied within 4 hours of the start of blast cleaning. Blasted surfaces shall be primed no later than the end of the same work day.

6.5.12 All cleaned surfaces must be approved by ICA FLUOR's Representative before the application of any paint.

6.5.13 A 12 inch wide strip of uncoated, blasted surface shall be left between primed and unblasted surfaces to prevent damage to the newly dried coating when additional blasting is done. When blast cleaning is resumed, the 12 inch strip of previously blasted surface shall require only a light brush blast to remove any rust that may be present. Cleaning shall be accomplished by holding the cleaning nozzle in a direction way from the coated surface.

6.5.14 All air compressors shall be of a sufficient size to deliver 100 psi at the nozzle. Each compressor shall have 2 oil/moisture filters, one located at the compressor air discharge and one located just before the after cooler. Compressed air used for blasting and coating must be clean, oil and water free and dry. Testing for evidence of oil or water shall be done daily and shall be in accordance with ASTM D4285.

6.5.15 Wet abrasive (slurry) blasting is an acceptable alternative to dry abrasive blasting but requires Owner approval.

7.0 PAINT SYSTEM APPLICATION NEW CONSTRUCTION

Except for field touch-up of coating damage, coating of field welds and painting of field fabricated tanks, all coating systems shall be shop applied (offsite) for fabricated assemblies if possible.

Paint shall be applied by one, or a combination, of the following methods:

Brushing Roller coating Air spraying Airless spraying Paint mitt (for items such as small diameter piping). The method of application shall be governed by the Paint Manufacturer's recommendation for the particular paint being applied. For application techniques, requirements and precautions, SSPC-PA 1 shall be used as a general reference.

No painting shall take place when the atmospheric temperature is below 50F, except when the surface temperature is below the dew point plus 5F, or when relative humidity is above 90% unless approved by the Paint Manufacturer and ICA FLUOR's Representative. Paint Manufacturer's recommendations shall be consulted in each case for possible special temperature requirements. No paints shall be applied to a surface at a temperature that will


cause blistering, porosity or otherwise be detrimental to the life of the paint.

Contact surfaces shall be painted as follows:

Contact surfaces of steel members to be joined by high-tensile bolting in friction- type joints shall be left unpainted, except for inorganic zinc primers as approved by AISC.

Steel coated in the shop or in the field before erection shall not be coated within two inches of the edges to be welded.

Steel surfaces in direct bonded contact with concrete, embedded in concrete or coated with concrete normally shall only be painted in specific cases where corrosion of the steel is expected to be a problem.

Steel to be embedded in brick or other masonry shall be given at least one prime coat. Steel surfaces in contact with aluminum surfaces shall be given at least one prime coat

of epoxy mastic. Surfaces not in direct bonded contact, but inaccessible after assembly, shall receive the

full specified paint system before assembly.

Surfaces shall not be recoated until the preceding coat has properly dried or cured.

Coatings shall be clean and dust free before applying the next coat. Loose zinc particles associated with overspray of inorganic zinc primers should be brushed or screened from the surface before applying topcoats. The surface may be considered ready for recoating when the next coat can be applied without the development of paint film irregularities, such as lifting or loss of adhesion of the undercoat. However, the minimum and maximum drying or curing times specified by the Paint Manufacturer shall be the acceptable recoat period. Paint shall not be force-dried under conditions which will cause cracking, wrinkling, blistering, formation of pores or which will be detrimental to its condition or appearance. Newly painted surfaces shall be protected to the fullest extent practicable from rain, condensation contamination, snow and freezing until the coating has dried.

All bolt heads, nuts, edges, corners, and crevices shall be stripe coated with primer by brushing or a single pass (if spraying) before the steel receives its first full prime coat. Striping shall extend 25 millimeters from all edges.

Successive coats of paint shall be of different colors. However, if this is not possible, then alternate coats shall be tinted to produce sufficient contrast to ensure complete coverage and specified film thickness of each coat. The final finish coat shall not be tinted. Tinting material shall be compatible with the paint and shall not be detrimental to its service life. Tinting in lieu of different colored intermediate coats shall require Owners approval.

Sprayed coatings shall be cross-spray-applied to insure uniform coverage, free of runs and sags.

When the Manufacturer's specified pot life limitation is reached, the material must be discarded and new material mixed. During hot weather pot life is significantly reduced. If there are indications, such as thickening or film build problems, that a material has reached the end of its pot life, the material must be discarded and new material mixed.


The generic type of paint to be used shall be in accordance with paragraph 4 and the attached systems given in Table 2. A listing of primers, intermediate and finish coating materials as well as approved manufacturers is given in Table 2.

Equivalent coatings of other manufacturers are acceptable, subject to prior approval of the ICA FLUORs representative.

When zinc rich primers are used, care shall be taken to avoid any possibility of over spraying or dripping onto austenitic stainless steel, duplex stainless steel, nickel alloy or 9% nickel steel components.

8.0 PAINTING OF PREVIOUSLY PAINTED SURFACES (MAINTENANCE PAINTING)

The surfaces to be painted shall be cleaned by blasting, power tools, hand tools or solvents, or by a combination of these methods. All grease, oil, dirt, foreign material, rust and loose, cracked, brittle or non-adhering paint shall be removed.

The remaining sound paint on the surface shall have the edges feathered by sanding prior to painting. Any paint that curls or lifts after the application of the spot or priming paint shall be removed and the area repainted.

Glossy surfaces shall be roughened by light sanding or a trisodium phosphate wash to provide a bond for successive coats of paint.

The minimum coating requirement for spot painting shall be as follows:

No rusting, prime coat exposed - apply 1 or 2 finish coats to regain specified mil thickness.

Rusted area or prime coat damaged - clean damaged or rusted area to base material and apply primer, intermediate and finish coats to regain specified mil thickness.

Existing paint coatings shall be checked or tested for compatibility with the paints with which they are to be over coated to ensure that lifting or wrinkling of the existing coating will not take place.

9.0 FIELD PROTECTION, CLEANUP AND SAFETY

The Contractor shall fully protect all equipment, walls, floors, ceilings and other surfaces from damage and shall provide the necessary drop cloths or other protection required to fully protect all surfaces from dust, paint droppings, paint mist, and other contaminants during the execution of his work.

While painting around switches and controls, painters shall be careful to avoid tripping of switches. It is imperative that all switches remain unmoved and undisturbed by painters.

All shipping tags, wires, strings and other means of temporary or shipping identification of surfaces to be painted shall be removed, but only after checking with and receiving authorization from ICA FLUOR's Representative.


The Contractor shall clean all surfaces, which have been spotted with paint such as window glass, floors, walls, equipment, etc., leaving the premises clean to the satisfaction of the Purchaser.

The Contractor shall provide a temporary shelter for storage and mixing of paint materials. Contractor shall provide adequate firefighting equipment, satisfactory to ICA FLUOR, for the temporary shelter and at all locations where painting work is in progress.

A protective hood with a positive fresh-air supply shall be used during blast cleaning operations.

A filter-type dust mask shall be used during hand tool or power tool cleaning operations in enclosed areas or in other situations where excessive concentrations of dust result.

Protective clothing, such as gloves, goggles and aprons shall be worn during pickling or solvent cleaning operations. Hands should be cleaned with a waterless hand cleaner after exposure to solvents. Clothing or protective equipment wet with solvent or paint should be promptly removed and laundered before reuse.

Prior to the start of daily work, the Contractor shall ascertain that all necessary tests have been made for toxic gases, chemicals or explosive mixtures (see API Standard 2015). The safety conditions covered by OSHA, as well as those deemed necessary by the Contractor shall be met.

Particular care must be exercised when working in close or confined spaces, especially when spraying. The Contractor shall ascertain that all necessary tests have been made for oxygen sufficiency and hydrogen sulfide. The threshold limit valve (TLV) prescribed by OSHA for the particular solvent vapor in the air shall not be exceeded unless fresh-air masks, as approved by the National Institute of Occupational Safety and Health (NIOSH), are supplied to workmen. When volatile solvents are flammable, the concentration in the air shall be kept to one-quarter or less of the lower explosive limit (LEL) by adequate exhaust or ventilation facilities.

10.0 INSPECTION

All phases of cleaning and painting operations of all shop and field painting shall be subject to spot check inspection by the ICA FLUOR's Representative. This periodic inspection will be made to ensure that the Contractor is accurately following the recommendations of this specification and the Paint Manufacturer's instruction. Spot check inspection does not relieve Paint Manufacturer and Contractor of their QA/QC responsibilities.

Surfaces prepared for painting are to be inspected and approved as satisfactory by the ICA FLUOR's Field Representative or Paint Inspector before any paint is applied by the Contractor. The Contractor shall also inspect all surfaces after cleaning and shall notify the ICA FLUOR's Field Representative of any defects, improper material or workmanship, or other conditions which in his opinion will affect the satisfactory performance and permanency of his work. Where such defects have been located, no painting shall be started until all such faulty conditions have been corrected or until a written agreement has been made with the ICA FLUOR's Field Representative regarding any subsequent defects


which may develop because of the conditions noted.

The ICA FLUOR's Inspector shall monitor wet and dry film thickness of the paint and shall compare his findings with those recommended. In cases of inadequate film build, the Contractor shall be required to recoat the surface at his own expense.

The Inspector shall determine the adequacy of:

Surface preparation using blast cleaning by comparison with NACE TM-01 prior to application of the first coat of paint.

Dry film thickness by measurement of each coat and of the total system by procedures specified in SSPC PA2.

The Contractor is required to keep an accurate daily record of air temperature, dew point and humidity conditions and the times of commencement and cessation of all phases of the cleaning and painting operations. These records shall be certified accurate by the Contractor painting supervisor and shall be available for inspection by the ICA FLUOR at all times. (Use Contractor Daily Paint Record.)

Holiday testing is not usually required for painted external coatings but may be required where the coating system will be exposed to excessive splash, spillage or water spray. Holiday testing is required for coatings under insulation.

The responsibility for the total cleaning and painting operations remain entirely with the Contractor who shall fully guarantee material and workmanship for the entire protective system. Inspection, approval or comments by the Purchaser, designated agents or by independent inspectors shall not relieve the Contractor of this responsibility.

The Contractor shall strictly adhere to the specifications and paint system proposals as submitted and approved by ICA FLUOR. Variations are not permitted without written approval of ICA FLUOR's Representative. Contractor will repair or replace any variations from accepted paint system proposal and these specifications at no cost to ICA FLUOR.

11.0 DISPOSAL OF PAINTING WASTE MATERIALS

All painting waste material disposal (liquid and/or solid) is the responsibility of the Contractor at his expense.
