2.3 If conflicts occur between this specification, the Painting manufacturer’srecommendations and the referenced standards, Reliance’s Specialist shall be contactedfor clarification.
3. General
3.1 References to SSPC shall be understood to refer to Steel Structures Painting CouncilStandards.
3.2 Work described shall be performed by the Painting Contractor and all tools, equipment,Paints, solvents, etc., necessary to complete the work shall be furnished by him.
3.3 The Painting Contractor shall comply with all applicable laws, regulations, ordinances,etc., of the city, country, state, province or nation pertaining to his work and paintingmaterials. It is mandatory requirement that all operatives working to this procedure takefull cognisance and implement necessary safety precautions.
3.4 Reliance’s Inspector shall have free access at all times to the work being performed by theContractor.
3.5 Painting Manufacturer’s latest approved published instructions for application and systemcombinations of coatings shall be followed. Superimposed primers and coatings shallbe compatible. In the event of conflicts, differences shall be brought to the Contractor’spainting specialist for resolution.
3.6 For equipment that has received shop prime coat, the Field Painting Contractor shalltouch-up prime coat and apply additional coats in accordance with the Painting Schedule.It is the Contractor’s responsibility to ensure compatibility between shop and field appliedpaint systems.
3.7 Proper precautions shall be taken to protect other surfaces from abrasive blasting, coatingover spray and spatter. Damage to other surfaces or equipment shall be repaired by theField Painting Contractor at his expense (see paragraph 10.6).
3.8 The Field Painting contractor shall submit surface preparation and application proceduresfor review and acceptance by the Reliance.
3.9 Stainless steel, Aluminium and other high-alloy materials shall not be coated unlessotherwise specified.
Austenitic stainless steels operating between 50oC and 200oC are at risk under certaincommon conditions to pitting corrosion or even stress corrosion cracking. For thisreason these substrates will be protected as indicated in Appendix ‘B’.
3.10 Painting Manufacturer’s instructions shall be followed as far as practicable at all times for proper storage to avoid exposure as well as extremes of temperature.
4. Surface Preparation
4.1 Metals
Reliance Engineering Associates Private Limited
G – GS - 005 Rev 0 Page 5 of 46
4.1.1 Adhesion of the paint film to surface depends largely on the degree of cleanliness ofthe metal surface. Proper surface preparation contributes more to the success of thepaint protective system.
4.1.2 Weld spatter shall be removed and sharp or rough welds rounded and contoured.Sharp edges shall be removed, chamfered or broken.
4.1.3 Surfaces to be painted shall be free of all grease, oil, loose rust and loose mill scale.Oil and grease shall be removed by solvent cleaning method as in SSPC-SP-1.
4.1.4 Rust, mill scale, weld spatter, flux shall be removed by methods indicated in thePainting Schedule.
4.1.5 The surface profile depth indicated under Appendix ‘A’ shall be achieved by using amedium that has good angularity of form, sharp cutting edges and is substantiallyfree from “half rounds”.
4.1.6 If sand is used as the blasting medium it shall be delivered to site in trucks. Eachtruck load shall be identified with a batch number and each batch shall be tested forChloride content (maximum allowable chloride level 0.03%) and pH value (the valueshould be nearly neutral i.e., pH 6 to pH 8). The tests shall be carried by owner, orby supplier with third party test certificate. The third party shall be an approvedagent approved by owner.
4.1.7 Profile measurements of abrasive blast cleaned surface shall be made with a KeaneTator profile comparator, Clemtec anchor profile chips, Testex Press-O-Film or othercontractor accepted method suitable for the abrasive being used.
4.1.8 Prior to any coating application the substrate shall be checked for soluble saltcontamination using a suitable salt contamination meter (SCM 400). The maximumallowable level of contamination shall be 5µ gm/cm2. Surfaces that do not meet thiscriteria shall be reprocessed.
Should this problem occur on a frequent basis the abrasive medium shall be re- examined for quality and if necessary changed.
4.1.9 Surfaces prepared for coating shall be coated the same day and before any visiblerusting occurs. (The time elapsed between blast cleaning and commencement ofpainting shall under no circumstances exceed 4 hours, but in any case mustcommence before signs of degradation occur).
4.2.0 The coating usually has a specific adhesion requirement and proper selection ofabrasive is most important. Generally, an abrasive is classified according to thefollowing characteristics:
a) Size - Usually by US sieve sizes (i.e., 16x40 mesh or 1.19 mm x 0.42 mm)
b) Shape - Irregular, round. Sharp
c) Hardness - Usually by Mohr’s Hardness scale of the present element
d) Colour - Light or dark
e) Chemical components - Abrasives shouldn’t contain undesirable components that

G – GS - 005 Rev 0 Page 6 of 46
would remain on surface being cleaned.f) Specific Gravity or Weight - Heavy abrasives clean faster and impact much better
while light weight abrasives are primarily used for polishing.g) pH of Abrasive - A neutral pH within the range of 7.0 ± 1 is desirable. Salt water
washed abrasives are not recommended.h) Availability and Cost
4.2.1 Metal etching will remove mill scale, rust and other containment from metal toproduce a white metal surface condition with an etch (anchor pattern) on thesurface. Light cleaning removes only old paint and loose rust.
4.2.2 Criteria for selection of abrasives are certain key physical and chemicalproperties of the abrasives. Not all abrasives provide the same surfacecleanliness. An abrasive effective for a commercial blast may not provide a nearwhite or white – metal blast cleaned surface. The coating system will thereforealso influence the choice of abrasive for surface preparation.
4.2.3 A consistent range of abrasive particle sizes must be maintained to produce aconsistent surface and cleaning rate.
4.2.4 The cleaning rate is affected with abrasive breakdown value. The greater theparticle breakdown the poorer the cleaning rate. Manufacturer’s certificateshould contain the breakdown value.
4.2.5 If the abrasive source is near seawater, routine checking for soluble chlorides is amust.
4.2.6 Visual inspection shall be carried-out to detect any sharp edges, weld spatter orvisible laminations. Where these are discovered they shall be ground smoothprior to coating.

5 Coating Preparation and Application
5.1 Coatings and primers shall be delivered to the job site in the original containers bearing the manufacturer’s name , product designation, batch number, shelf life and date of manufacture. Before application, they shall be stirred or agitated until the ingredients are completely mixed. Material which have exceeded the manufacturer’s recommended shelf life shall not be used. Materials shall not be used or mixed into a new batch after its recommended pot life has been exceeded. Material shall be used on a first-in, first-out basis.
5.2 To facilitate proper stirring, the paint containers shall have mouth at the top centre.
5.3 Field application shall be by brush, roller or spray gun. Local regulations regardingspray and roller coating shall be observed. A smooth uniform film shall be applied to thesurfaces to be coated.
5.4 The temperature of the substrate must be a minimum of 3oC above the dew point duringabrasive blast cleaning and coating. The substrate temperature shall be a minimum of5oC and a maximum of 60oC during coating application.
5.5 Painting shall be applied in strict accordance with the painting manufacturer’s latestpublished instructions. In particular, the manufacturer’s recommended curing or dryingtime shall be allowed between coats of primer and finish. Thickness of the paintingshall be in accordance with the Painting schedule or the manufacturer’s latest publishedinstructions. In the event of conflict, differences shall be brought to the attention of theReliance’s painting specialist for resolution.
5.6 Paints, catalysts and thinners shall be stored in well ventilated buildings free fromexcessive heat, sparks, flames and direct sunlight. Paints stored for short times on thejob site shall be protected from direct sunlight during the summer months.
5.7 For Field joint coating where blast cleaning is not possible, minimum ST2 surfacepreparation to be achieved. The field paint shall be compatible to ST2 surface finish aswell as to existing paint at the adjoining area.
5.8 The life time of any protective system is determined by the dry film thickness of the paintsystem present on weld seams and sharp edges. Special attention should be given tosharp edges to ensure that they are covered with an adequate coating thickness.
5.9 Two component (base and hardener) coatings like Air drying epoxy, Polyurethanecoatings etc shall be mixed in the ratio recommended by manufacturer to ensure properand complete curing of the coatings. Improper ratio leads to problems like soft / non-dried film, poor performance, etc. The base and hardener are to be separately mixedfirst to obtain a homogenous mixture. The hardener is to be added to the base slowly,with continuous mixing / agitation and not the reverse. Power agitation is preferredover hand mixing.
5.10 Any addition of thinner to achieve the application viscosity should be made only after the components are thoroughly mixed. Avoid using excess thinner than the recommended volumes, since this will lead to lower DFT build up, sagging, longer curing time, etc.

5.11 Painting should not be undertaken during fog or mist conditions or when rain or snow is imminent, when the surface to be painted is wet with condensation or when condensation can occur during the initial drying period of the paint.
5.12 The volume solids figure given in the product data sheets of paints is the percentage of the film obtained from a given wet film thickness under specified application and conditions. The theoretical coverage can be determined from the formula below:
Theoretical coverage (m2 / Litr) = Volume solids (%) x 10
Measured dft (in microns)5.13 Pump pressure and correct tip sizes will be used to produce the most desirable spray size pattern and thickness on airless spray equipment.
5.14 When using conventional spray equipment, the operator will ensure that the gun parts and outlets are maintained in a clean and working order to ensure the best of cosmetic appearance upon application.
5.15 Coating containing heavy or metallic pigments that have a tendency to settle shall be kept in suspension by continuous use of a mechanical agitator whilst being applied, to ensure uniformity over the surface area (e.g., zinc MIO’s pigmented materials).
5.16 All edges, corners, webs and inaccessible areas, shall be strip coated prior to full application. To ensure integrity of WFT/DFT over surface areas.
6 Inspection
6.1 Inspection will be performed by an inspector authorised by Reliance.
6.2 Prime coats shall be inspected and cleaned when required by Reliance’s Inspector, beforeapplying finish coats.
6.3 Dry film thickness shall be measured after each coat by Reliance’s Inspector using aMikrotest, Elcometer, or Reliance accepted equal.
6.4 The Painting Contarctor’s supervisor shall have in his possession at all times a wet filmthickness gauge for continuous check of the wet film as applied.
6.5 Defective work shall be corrected by the Painting Contractor at his sole expense.
6.6 When more than one prime coat or finish coat is specified, use a contrasting colour in thefirst coat to distinguish between the first and second coats.
6.7 The average value of thickness readings taken over any square meter of a scheduled areashould be equal or exceed the nominal thickness specified and in no case should anyreading be less than 75% of the nominal thickness.

G – GS - 005 Rev 0 Page 10 of 46
6.8 Areas where coating thickness either thin or too thick are to be marked and Paint contractorto carry-out repair at such areas. The surface areas shall be inspected to find holidays,runs, sags etc. Holidays, if detected shall be coated before full drying taking place. Runsand sags will be brushed out.
6.9 Determination of the thickness of each coat in a multi-coat system should be an inspectionhold-point. When using magnetic gages to measure multi-coat systems, the average of thefirst coat must be determined prior to application of second coat. Readings taken after thesecond coat is applied will obviously be the total thickness of the two coats combined, andthe specific thickness of the second coat can only be determined by subtracting the averagethickness obtained from the first coat reading.
6.10 Holiday or spark testing shall be done for immersion service to find the nicks, scrapes, andpin holes in the coating film. Holiday testing shall be done after application of either thenext to last, or last coat of paint.
6.11 After all the coats of paint have been applied, the inspector should verify that theappropriate clean-up is done, and that any abrasions, nicks, or scrapes are repaired asrequired. If the coating is within the specification the item will be offered to the client orrepresentative inspector where required.
6.12 Occasionally, there is a need to test the adhesion of the coatings after application.“ Measuring adhesion by Tape Test” as described in ASTM D – 3359 shall be used foradhesion test.
6.13 Surface preparation and coating shall be documented using the Format No. 1 (Surfacepreparation and Coatings Inspection Form).
