2.3 If conflicts occur between this specification, the Painting manufacturer’s recommendations and the referenced standards, Reliance’s Specialist shall be contacted for clarification.
3. General
3.1 References to SSPC shall be understood to refer to Steel Structures Painting Council Standards.
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 painting materials. It is mandatory requirement that all operatives working to this procedure take full cognisance and implement necessary safety precautions.
3.4 Reliance’s Inspector shall have free access at all times to the work being performed by the Contractor.
3.5 Painting Manufacturer’s latest approved published instructions for application and system combinations of coatings shall be followed. Superimposed primers and coatings shall be compatible. In the event of conflicts, differences shall be brought to the Contractor’s painting specialist for resolution.
3.6 For equipment that has received shop prime coat, the Field Painting Contractor shall touch-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 applied paint systems.
3.7 Proper precautions shall be taken to protect other surfaces from abrasive blasting, coating over spray and spatter. Damage to other surfaces or equipment shall be repaired by the Field Painting Contractor at his expense (see paragraph 10.6).
3.8 The Field Painting contractor shall submit surface preparation and application procedures for review and acceptance by the Reliance.
3.9 Stainless steel, Aluminium and other high-alloy materials shall not be coated unless otherwise specified.
Austenitic stainless steels operating between 50oC and 200oC are at risk under certain common conditions to pitting corrosion or even stress corrosion cracking. For this reason 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
4.1.1 Adhesion of the paint film to surface depends largely on the degree of cleanliness of the metal surface. Proper surface preparation contributes more to the success of the paint 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 the Painting Schedule.
4.1.5 The surface profile depth indicated under Appendix ‘A’ shall be achieved by using a medium that has good angularity of form, sharp cutting edges and is substantially free from “half rounds”.
4.1.6 If sand is used as the blasting medium it shall be delivered to site in trucks. Each truck load shall be identified with a batch number and each batch shall be tested for Chloride content (maximum allowable chloride level 0.03%) and pH value (the value should be nearly neutral i.e., pH 6 to pH 8). The tests shall be carried by owner, or by supplier with third party test certificate. The third party shall be an approved agent approved by owner.
4.1.7 Profile measurements of abrasive blast cleaned surface shall be made with a Keane Tator profile comparator, Clemtec anchor profile chips, Testex Press-O-Film or other contractor accepted method suitable for the abrasive being used.
4.1.8 Prior to any coating application the substrate shall be checked for soluble salt contamination using a suitable salt contamination meter (SCM 400). The maximum allowable level of contamination shall be 5µ gm/cm2. Surfaces that do not meet this criteria shall be reprocessed.
Should this problem occur on a frequent basis the abrasive medium shall be examined for quality and if necessary changed.
4.1.9 Surfaces prepared for coating shall be coated the same day and before any visible rusting occurs. (The time elapsed between blast cleaning and commencement of painting shall under no circumstances exceed 4 hours, but in any case must commence before signs of degradation occur).
4.2.0 The coating usually has a specific adhesion requirement and proper selection of abrasive is most important. Generally, an abrasive is classified according to the following 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
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 to produce a white metal surface condition with an etch (anchor pattern) on the surface. Light cleaning removes only old paint and loose rust.
4.2.2 Criteria for selection of abrasives are certain key physical and chemical properties of the abrasives. Not all abrasives provide the same surface cleanliness. An abrasive effective for a commercial blast may not provide a near white or white – metal blast cleaned surface. The coating system will therefore also influence the choice of abrasive for surface preparation.
4.2.3 A consistent range of abrasive particle sizes must be maintained to produce a consistent surface and cleaning rate.
4.2.4 The cleaning rate is affected with abrasive breakdown value. The greater the particle breakdown the poorer the cleaning rate. Manufacturer’s certificate should contain the breakdown value.
4.2.5 If the abrasive source is near seawater, routine checking for soluble chlorides is a must.
4.2.6 Visual inspection shall be carried-out to detect any sharp edges, weld spatter or visible laminations. Where these are discovered they shall be ground smooth prior 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 regarding spray and roller coating shall be observed. A smooth uniform film shall be applied to the surfaces to be coated.
5.4 The temperature of the substrate must be a minimum of 3oC above the dew point during abrasive blast cleaning and coating. The substrate temperature shall be a minimum of 5oC and a maximum of 60oC during coating application.
5.5 Painting shall be applied in strict accordance with the painting manufacturer’s latest published instructions. In particular, the manufacturer’s recommended curing or drying time shall be allowed between coats of primer and finish. Thickness of the painting shall be in accordance with the Painting schedule or the manufacturer’s latest published instructions. In the event of conflict, differences shall be brought to the attention of the Reliance’s painting specialist for resolution.
5.6 Paints, catalysts and thinners shall be stored in well ventilated buildings free from excessive heat, sparks, flames and direct sunlight. Paints stored for short times on the job 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 surface preparation to be achieved. The field paint shall be compatible to ST2 surface finish as well 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 paint system present on weld seams and sharp edges. Special attention should be given to sharp edges to ensure that they are covered with an adequate coating thickness.
5.9 Two component (base and hardener) coatings like Air drying epoxy, Polyurethane coatings etc shall be mixed in the ratio recommended by manufacturer to ensure proper and 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 mixed first 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 preferred over 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, before applying finish coats.
6.3 Dry film thickness shall be measured after each coat by Reliance’s Inspector using a Mikrotest, Elcometer, or Reliance accepted equal.
6.4 The Painting Contarctor’s supervisor shall have in his possession at all times a wet film thickness 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 the first 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 area should be equal or exceed the nominal thickness specified and in no case should any reading be less than 75% of the nominal thickness.
6.8 Areas where coating thickness either thin or too thick are to be marked and Paint contractor to 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. Runs and sags will be brushed out.
6.9 Determination of the thickness of each coat in a multi-coat system should be an inspection hold-point. When using magnetic gages to measure multi-coat systems, the average of the first coat must be determined prior to application of second coat. Readings taken after the second coat is applied will obviously be the total thickness of the two coats combined, and the specific thickness of the second coat can only be determined by subtracting the average thickness obtained from the first coat reading.
6.10 Holiday or spark testing shall be done for immersion service to find the nicks, scrapes, and pin holes in the coating film. Holiday testing shall be done after application of either the next to last, or last coat of paint.
6.11 After all the coats of paint have been applied, the inspector should verify that the appropriate clean-up is done, and that any abrasions, nicks, or scrapes are repaired as required. If the coating is within the specification the item will be offered to the client or representative 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 for adhesion test.
6.13 Surface preparation and coating shall be documented using the Format No. 1 (Surface preparation and Coatings Inspection Form).
