3 PAINTING PROCEDURE 3.1 General

The scope of these prescriptions is to establish materials and workmanship such as to ensure a first quality and homogeneous work. Such prescriptions are summarized on a general painting schedule. The Contractor shall forward to EMPLOYER its own painting schedule, made on the basis of the prescription of the present chapter. The Contractor schedule shall include description of each part with relevant shop and site painting treatments and an affidavit of compliance, stating that all materials and work will comply, or have complied, with the applicable requirements of these Specifications. Parts to be painted, with relevant painting prescriptions, are indicated in the painting schedule. The prescriptions shall be applied to all minor parts which are included in the Supply even if not mentioned in the schedule. Surface of stainless steel, copper and copper alloys, rubber, glass and surfaces to be embedded in concrete need not be painted, unless otherwise specified. Any part of the Supply that shall have to undergo a special painting, will be specifically mentioned in the various Sections of the Technical Specifications. Painting will be carried out in accordance with the instructions and recommendations of the paint manufacturers, as approved by EMPLOYER. Any equipment that is not likely to be damaged during erection shall be finish painted at the shop, while it shall be primed and top coated only, whenever the erection shall be deemed to damage the paint. Such equipment shall be finish-painted (or intermediate and finish-painted) at site by the Contractor, after erection has been completed. Shop painting shall be protected against damages during transport by wooden pads or other suitable means. Nevertheless, the Contractor shall furnish the paint for any touch up that will be required after the erection has been completed. The paints to be supplied for the site painting shall not be less than one hundred and twenty percent (120%) of the estimated required quantity.

3.1.1 Surface to be painted Steel structure & supports

3.2 Surface Preparation All surfaces required to be painted, either at the shop or at site, shall be thoroughly cleaned so as to remove, even where access is difficult, any dirt and foreign matter and to obtain a smooth and dry surface. In the preparation of metal surfaces, all welds, beads, blisters and any defect shall be smooth ground and pits and dents compound filled to obtain a clean and smooth surface. Ferrous metals shall have all rust, dust and scale removed by sand-blasting. Oily and greasy surfaces shall be cleaned using suitable solvents and dried with compressed air blows. In any case the state of surfaces shall be in accordance with the SSPC Standards requirements. Non ferrous metals and galvanized steel shall be thoroughly cleaned by solvent, by washing and/or brushing. All metallic machined surfaces and surfaces not required to be painted shall be covered with a protective coating of wax or oil. Unassembled pins and bolts shall be oiled and wrapped with moisture resistant paper or protected by other suitable means. The interior surfaces of piping, valves and other parts that have to undergo hydraulic tests shall be painted before such test, unless otherwise specified. All the protective coatings shall be effective against salt air in the case of transport by sea and shall be easily removable, if required.

3.3 Paints and Painting Equipments The paints and the paint products shall be a standard type of well-known manufacturer, and a reference list of past performances in similar power plants shall be submitted to EMPLOYER by the Contractor. All paints used shall be produced by the same manufacturer where possible and the Contractor shall however be responsible for the choice of compatible coatings. Painting equipment shall conform to paint manufacturers recommendations. Materials shall be delivered to the site in the manufacturer sealed container, bearing the manufacturer labels indicating type and grade of content.

3.4 Application of Paint General Standards The prime coat shall be applied immediately following blasting and cleaning, before any condensation might occur on the prepared surface. No paints shall be applied over dust, grease, oil or other incompatible matter. No paints shall be applied during rainy or foggy weather, when the air



temperature is below 10C or above 40C or when the surface temperature is below 5C or above 50C, and when air relative humidity is over 80% or air temperature is less than 2.5C above the dew-point. Paints shall not be applied even if the above conditions are forecast to prevail within one day from scheduled paint application. Enclosures and heating shall be provided as necessary to prevent dust circulation, to achieve required temperature and to protect the finished surfaces. The time schedule for successive coats of paint shall be such as to allow the first coat to dry hard and to be in required state to receive the second coat. The color of successive coats of paint must be different to allow easy identification of the sequence of painting, for control purposes. The paint film must adhere perfectly to the painted surface. The Contractor shall pay particular care in applying the prescribed paint thickness even where access is difficult or over corners and edges. To comply with the prescriptions, additional coats shall be applied by brush or by spray until a satisfactory result is achieved. Coating shall be applied in a workmanlike manner, so that the finished surfaces shall appear free from drops, waves, laps, bubbles, brush marks or other defects.

3.5 Zinc Plating

The zinc protective coat shall be applied by bath of electrolytic process. It shall be adherent, smooth and free from discontinuity and imperfections, such as bubbles, porosity, cracks or other irregularities that may affect the soundness of the protective layer. The plating thickness shall correspond to a minimum rate of 600 g/m. The adhesiveness of the protective layer shall be such as no to be removable during normal handling, transport and assembly operations. After immersion in the molten zinc bath the protected surfaces shall not be submitted to any process of scraping or wiping that may reduce the uniformity of the thickness of the protective coat. Items plated by electrolytic process shall be dehydrogenated after plating.

3.5.1 Repair of galvanized surfaces Zinc based solder repair of galvanizing is the preferred method for field repair and shall be used wherever possible. However, inorganic zinc, 3 mils dry film



thickness compound may be in the field as a substitute.

3.6 Colors The Contractor shall comply with the requirements of the EMPLOYER as far as identification colors are concerned. EMPLOYER shall entrust, after the award of the Contract, a complete list of colors for the equipment not covered by the EMPLOYERs requirements. The Contractor shall submit for approval to EMPLOYER painted samples, 150 x 300 mm.

3.7 Shop Painting All parts shall be provided with a priming coat in the shop subsequent coats may only be applied on to carefully cleaned basic coats. All parts like openings & hollow parts have to be closed or the parts have to be packed with suitable protection prior to transport.

3.8 Site Painting After the erection or assembly of structures & equipment at site damaged & defective shop coats shall be touched up with new same type of paint as used for the shop coats. The work shall include removal of the damaged paint work, surface preparation of all exposed area & application of paint. Site welds must be treated as soon as possible after welding. During application of paint at site care must be taken to protect building, floors, structures, electrical, equipment including motors, valve stems, glass, moving parts, bearing, couplings, shafts, lubrication points & other sensitive parts.

3.9 Touch-Up Painting The Contractor shall touch up all destroyed or damaged surfaces before painting. Touch-up painting shall be with brush or airless spray after SSPC-SP3 cleaning. If the touch up area is wide and blasting operation is possible, spray coating method shall be applied after re-blasting. The Contractor shall provide sufficient quantity of touch-up paint of the same types and colors as applied for shop painting. The Supplier shall provide not less than 5% of total paint quantity, unless otherwise specified. 1) Bare steel surface where the surface rusts
