be shown. Materials older than their stated shelf life shall not be used. Coating material

which has gelled or otherwise deteriorated during storage shall not be used.

4.3 All ingredients in any container shall be thoroughly mixed before use to a smooth and

uniform consistency. Mechanical agitation during application shall be sufficient to keep

pigment in solution as per manufacturer’s recommendations.

4.4 Coating material mixed in the original container shall not be transferred until all settled,

pigment is incorporated in the vehicle. This does not imply that part of the vehicle may not

be poured off temporarily to simplify the mixing.

4.5 Coating material shall not be mixed or kept in suspension by using a bubbling air stream.

4.6 Where a skin has formed in the container, the skin shall be cut loose and discarded. If such

skins are sufficiently thick to have a practical effect on the composition and quality, the

paint shall not be used.

4.7 All pigmented material shall be strained after mixing except where application equipment is

provided with adequate strainers. Strainers shall be capable of passing the pigment and

removing any skin.

4.8 Material which does not have a limited pot life, or does not deteriorate on standing may be

mixed any time before using, but if settling has occurred, it must be re-mixed immediately

before using. Coating material shall not remain in spray pots or buckets overnight but shall

be gathered into a closed container and re-mixed before use.

4.9 No thinner shall be added unless necessary for proper application. Thinning shall not

exceed limitation established by manufacturer and only thinners specified by the

manufacturer shall be used.

4.10 Type of thinner shall comply with manufacturer’s instruction.

5.0 COATING PROCEDURE

5.1 Paint Material (Coating Systems)

5.1.1 The Type, Brand, Number of coats, Colour, and Dry film thickness shall be per 9.0, 10.0 and

11.0 herein

.

5.1.2 Manufacturer’s instructions, including safety precautions, are a part of this specification. In

case of conflict, the manufacturer’s mandatory instructions shall govern.

5.1.3 The compatibility of finishing coat with the primer/tie coat shall be confirmed from the

manufacturer. In no case shall the coatings of different manufacturer be mixed in any one

system.

5.2 Application

Paint application is normally by airless spray. Use of Air spray/brush application can be

followed only after getting written approval by Engineer-in-charge only for limited areas.

5.2.1 Surface shall not be coated in rain, wind, snow, fog, mist, or in areas where injurious

airborne elements exist, when the steel surface temperature is less than 3ºC above dew point

or when the relative humidity is greater than 85%, or when the temperature is below 5ºC. In

case the fabrication yard is selected at such a place where normal temperature is below 5ºC,

the contractor shall propose alternate coating procedure for Company’s approval at the

bidding stage itself. The company(owner) has the right to suspend the application of coating

when the damage to the coating may result from actual or impending weather conditions.

5.2.2 Blast cleaned surfaces shall be coated with one complete application of primer as soon as

practicable but in no case later than 4 hours on the same day as blast cleaned. Coating shall

not be applied within 75mm of an un-blasted surface.

5.2.3 To the maximum extent practicable, each coat of material shall be applied as a continuous

film of uniform thickness free of pores. Any thin spots or areas missed in the application

shall be re-coated and permitted to dry before the next coat is applied.

5.2.4 To reduce the possibility of inter-coat contamination and assure proper adhesion between

successive coats, all coats shall be applied as soon as possible after the minimum specified

drying time of the preceding coat. Material shall be considered dry for recoating when an

additional coat can be applied without the development of any detrimental film

irregularities, such as lifting or loss of adhesion of the undercoat.

5.2.5 When successive coats of the same color have been specified, alternate coats shall be tinted,

when practical, sufficiently to produce enough contrast to indicate complete coverage of the

surface. When the material is the color of the steel, or when the tinting of the final coat is

objectionable, the first coat to be applied shall be tinted. The tinting material shall be

compatible with the coating material and not detrimental to its service life.

5.2.6 Brush application of paint shall be in accordance with the following:

a. Brushes shall be of a style and quality that will enable proper application of paint.

Round or oval brushes are most suitable for rivets, bolts, irregular surfaces, and

rough or pitted steel. Wide, flat brushes are suitable for large flat areas, but they

shall not have a width over five inches.

b. The brushing shall be done so that a smooth coat as nearly uniform in thickness as

possible is obtained.

condensed water or oil.

Ingredients shall be kept properly mixed in the spray pots or containers during application

by continuous mechanical agitation.

The pressure on the material in the pot and of the air at the gun shall be adjusted for

optimum spraying effectiveness. The pressure on the material in the pot shall be adjusted

when necessary for changes in elevation of the gun above the pot. The atomizing air

pressure at the gun shall be high enough to properly atomize the paint but not so high as to

cause excessive fogging of paint, excessive evaporation of solvent, or loss by over spray.

Spray equipment shall be kept sufficiently clean so that dirt, dried paint, and other foreign

materials are not deposited in the paint film. Any solvent left in the equipment shall be

completely removed before applying paint to the surface being painted.

Paint shall be applied in uniform layer, with overlapping at the edge of the spray pattern.

The spray pattern shall be adjusted so that the paint is deposited uniformly. During

application, the gun shall be held perpendicular to the surface and at a distance which will

ensure that a wet layer of paint is deposited on the surface. The trigger of the gun should be

released at the end of each stroke.

All runs and sags shall be brushed out immediately or the paint shall be removed and the

surface repainted.

Areas inaccessible to the spray gun shall be painted by brush; if not accessible by brush

daubers, or sheepskins shall be used. Brushes shall be used to work paint into cracks

crevices, and blind spots which are not adequately painted by spray.

Particular precautions are necessary in spraying inorganic zinc. These are listed in the

manufacturer’s instructions.

5.2.8 Airless spray application shall be in accordance with the following procedure: as per steel

structure paint Manual Vol.1 & Vol.2 by SSPC, USA, Air less spray relies on hydraulic

pressure rather than air atomisation to produce the desired spray. An air compressor or

electric motor is used to operate a pump to produce pressures of 1,000 to 6,000 psi. Paint is

delivered to the spray gun at this pressure through a single hose within the gun, a single

paint stream is divided into separate streams, which are forced through a small orifice

resulting in atomization of paint without the use of air. This results in more rapid coverage

with less over spray. Airless spray usually is faster, cleaner, more economical and easier to

use than conventional air spray.

Airless spray equipment is mounted on wheels, and paint is aspirated in a hose that sucks

paint from any container, including drums. The unit shall have inbuilt agitator that keep the

paint uniformly mixed during the spraying. The unit shall consists of inbuilt strainer. Usually

very small quantities of thinning is required before spray. In case of High Build epoxy

coatings(two pack). 30:1 pump ratio and 0.020-0.023" tip size will provide a good spray

pattern. Ideally fluid hoses should not be less than 3/8" ID and not longer than 50ft to obtain

optimum results.

In case of gun choking, de-choking steps shall be followed immediately.

5.2.9 All nameplates, manufacturers’ identification tags, machined surfaces, instrument glass,

finished flange faces, control valve stems and similar items shall be masked to prevent

coating deposition.

5.2.10 If these surfaces are coated the component shall be cleaned and restored to its original

condition.

5.2.11 Edges of structural shapes and irregular coated surfaces shall be coated first and an extra pass

made latter.

5.2.12 Wet paint shall be protected against contamination from dust or other foreign matter.

5.3 Drying of Coated Surfaces

5.3.1 No coat shall be applied until the preceding coat has dried. The material shall be considered

dry for re-coating when another coat can be applied without the development of any film

irregularities such as lifting or loss of adhesion of undercoats, and the drying time of the

applied coat does not exceed the maximum specified for it as a first coat.

5.3.2 No paint shall be force dried under conditions which will cause checking, wrinkling,

blistering, formation of pores, or detrimentally affect the condition of the paint.

5.3.3 No drier shall be added to paint on the job unless specially called for in the manufacturer’s

specification of the paint.

5.3.4 Paint shall be protected from rain, condensation, contamination, snow and freezing until dry

to the fullest extent practicable.

5.4 Repair of Damaged Paint Surfaces.

5.4.1 Where shop paint has been damaged in handling, all damaged and loosely adhering paint

shall be removed and the surface thoroughly cleaned. Edges of the breaks shall be

feathered, and the designated number of prime and finish coats applied to the thickness

specified.

6.0 INSPECTION

Procedures for testing and documentation for quality control shall be prepared prior to the

initial start up of any work covered by this specification. The procedure shall include

1.0 SCOPE

The following sections outlines the requirement of supply, application and testing of

thermally sprayed aluminum coatings (TSAC) for corrosion protection of steel structures

exposed to sea water or any immersion service, splash zone, atmospheric or salt spray

exposure, sulfurous flue gases not exceeding 500 0 C and other hostile environments.

2.0 ITEMS TO BE THERMALLY SPRAYED

Steel Structures/equipments to be protected by TSAC shall as per Section 11.0 of specification

A097- 00-06-42-SP-03, Rev.1. Structures, components thermally sprayed shall not have any

uncoated area or shall not be in mechanically connected by flanges etc to any uncoated bare

steelwork. Such adjacent areas to TSA coated areas, if not coated by TSA shall have suitable paint

coating system as per Specification A097-00-06-42-SP-03, rev.1.

3.0 TSAC REQUIREMENTS

3.1 Surface Preparation

All the parts to be sprayed shall be degreased according to SSPC-SP 1. The absence of oil and

grease after degreasing shall be tested by method given elsewhere in the specification (Refer Sec.

6.7). Thereafter the surface to be abrasive blasted to white metal finish as per NACE 1/SSPC-SP 5

for marine and immersion service. Using SSPC VIS 1, it is to be visually assesed that the blast

cleaned surface meets requirement of SSPC-SP 5. Thereafter clear cellophane tape test as per ISO

8502-3shall be used to confirm absence of dust on the blasted surface. Finally blasted surface shall

be tested for presence of soluble salts as per method ISO8502-9 . Maximum allowable salt content

shall be considered 50mg/M2. ( 5 micrograms/cm2 ) .In case salt content exceeds specified limit

The contaminated surface shall be cleaned by method as per Annex –C of IS 12944-4 ( Water

Cleaning.) After cleaning the surface shall be retested for salt content after drying.

The blasting media shall be either chilled iron or angular steel grit as per SSPC-AB-3 of mesh size

G-16 to G-40. Copper or Nickel slag or Garret as abrasive will also be suitable having mesh size in

the range of G16 to G24, conforming to SSPC-AB-1. Mesh size shall be required as appropriate to

the anchor tooth depth profile requirement and blasting equipment used. The blasted surface should

be having angular profile depth not less than 75 microns with sharp angular shape. The profile

depth shall be measured according to NACE standard RP 0287 (Replica Tape) or ASTM D 4417

method B (Profile depth gauge).

For manual blasting one profile depth measurement shall be taken every 10-20 M2

of blasted

surface.

Surface preparation shall be completed in one abrasive blast cleaning operation wherever possible.

If rust bloom(visual appearance of rust ) appears on the blast cleaned surface before thermal

spraying, the affected area shall be reblasted to achieve specified degree of cleanliness after which

only thermal spraying shall commence.

Air blasting pressure at nozzle shall be normally maintained at 100 psi. Air pressure and media size

should be reduced and adjusted to preclude damage/distortion to thin gauge materials. Blasting time

on work piece should be adjusted to only clean the surface and cut required anchor tooth with

minimum loss of metal. Blast angle should be as close to perpendicular as possible but in no case

greater than 30 0

from perpendicular to work surface. Blasting media must be free of debris,

excessive fines, contaminants such as Nacl and sulfur salts (Ref. SEC 6.0 of this Spec).

.




A097-00-06-42-TSA-SP-03 Rev. 1

Page 4 of 11


3.1.1 Blasting Equipment

The TSAC applicator shall use mechanical (centrifugal wheel) or pressure pot blast cleaning

equipment and procedures. Suction blasting equipment shall not be used. Sec 6.6.2 shall be used to

validate clean and dry air

3.1.2 Feed Stock

The feed stock shall be in the form of wire. The feed stock shall be 99.5% aluminum of

commercial purity grade, its composition shall be in accordance with requirement of BS 1475or

ASTM B833 (wrought aluminum and aluminum alloys, wire).

3.1.3 Thickness Requirement

The nominal thickness of finished TSAC shall be 225 microns having minimum value of 200

microns at low thickness areas (valleys) and not more than 250 microns at peak areas.

The finished thickness shall be measured using SSPC-PA 2 type 2 fixed probe gauge (Magnetic
