SECTION 6

SURFACE PREPARATION




6. SURFACE PREPARATION

6.1 General

The surface preparation required on all materials is as specified in

Appendix A - (schedule of treatments), and is the minimum expected

before the application of the paint system. All surface preparation shall

be carried out after complete fabrication of any item unless approved by

ADGAS.

6.2 Steel surfaces to receive paint

6.2.1 Shop Preparation

Shop preparation shall consist of one, or a combination of the

following methods in order to achieve the required surface, but the

initial method is preferred:-

(a) Blast clean to ISO-8501 (05 5900/BS7079) to one of the grades

specified. The types and grades of abrasives used for blast

cleaning shall conform strictly to the requirements of BS 7079.

The use of abrasives containing silica is not permitted. After

blast cleaning and before application of the priming coat the

surface shall be vacuum cleaned to remove dust and abrasives.

Due care shall be exercised to prevent the abrasive grit entering

inside equipment and pipework. On completion of blasting

operations the inside of equipment and piping shall be

inspected and cleaned out if the presence of abrasive grit is

detected.

Only Aluminium Oxide/ Natural Garnet/Stainless steel

abrasives shall be used on stainless steel equipment/pipe work.

(b) Pickling by either Sulphuric Acid or Phosphoric Acid strictly in

accordance with a recognized procedure such as SSPC-SP8

(Steel Structure Painting Council).

(c) Power Tool cleaning, rotary wire brushing etc.

(d) Hand cleaning by scraping or wire brushing to localized areas of

mechanical damage, can only be accepted when paint film is

not damage fully back to bare steel.




6.2.2 Shop Priming Coats

The use of temporary or holding shop primers shall not be

employed, all coatings applications applied at shop shall be in

strict accordance with the requirements of the painting Schedules

A, B, C.

Should vendor’s items be required to employ a temporary/holding

shop primer for transit requirements, all works shall involve the

complete removal of the shop primer and coated to the required

ADGAS Painting Specification prior to installation at site.

N.B: It should be noted that the responsibility of quality assurance

and control rests first and for most with the vendor.

The absence of an ADGAS approved inspector does not in

any way relieve the vendor of any QA/QC obligation.

6.2.3 Site Preparation

Site preparation shall consist of one or a combination of the

following:-

(a) Surface cleaning shall remove all surface contamination

including dirt or grease in accordance with SSPC-SP1

(solvent cleaning and high pressure sweet water washing

with emulsified cleaning agents).

Potable water used for cleaning shall have a chloride

content of less than 30ppm.

Prior to blast cleaning, steelwork shall be dressed, so all

weld splatter and laminations etc. should be removed by

grinding.




(b-1) Blast cleaning to ISO 8501-1-1988 (05 5900/BS 7079). Due

care shall be exercised to prevent other areas and wet

painted surfaces from contamination. Contractors shall

erect necessary screens around the work area to prevent

contamination. Abrasive shall not be allowed to enter the

inside of equipment and piping.

Natural Garnet is the only acceptable substance to be used

with a particle size of between 0.85 and 0.5mm. This can be

used for both carbon and stainless steel equipment and pipe

work.

Before any blasting occurs in a site location the enclosed

form Appendix D must be filled in and signed by the

appropriate personnel responsible. This is in line with

ADGAS Standing Instruction No. H-10-1.

(b-2) Where blast cleaning to Sa 2,5 (near white metal cleaning) is

not advisable due to substrate excessive corrosion, portable

spot blast cleaning equipment with straight bore nozzle

operating at lower pressure (less than 50 psi) can be used.

Spot blast equipment with straight bore nozzle to be kept

far away from the substrate (more than two foot distance.)

while Carrying out SWEEP blast cleaning.

(c) Power tool cleaning using impact tools, rotary wire brushes

and flap discs.

(d) Hand cleaning by scraping or wire brushing.

(e) It should be noted, that mechanical or hand cleaning must

be considered marginal as this method of surface

preparation will not remove mill scale, rust or provide a

surface profile/anchor pattern.

(f) Ultra High Pressure Water Jetting (with or without

abrasive) - at pressure up to 25,000 to 30,000 psi shall only

be considered for use on site pending full ADGAS approval.

6.2.4 Nuts and Bolts

Surface preparation shall be directed to achieve the same standard

as the adjacent surfaces.

6.2.5 Aluminium Surfaces

No preparation or painting is required.




6.2.6 Galvanized Surfaces to receive paint

Surface preparation shall consist of thoroughly degreasing and

treating with a mordant solution (comprising of a phosphoric acid

solution incorporating copper salts in a solvent/water solution-‚T‛

wash or similar).

After the reaction period the surfaces shall be cleaned with potable

water.

Note: Weathered galvanized surfaces should be wire brushed or

blast cleaned if required, first to remove all corrosion

products.

6.2.7 Weld areas and difficult corners

All weld seams, sharp edges and surface irregularities shall be

contoured and surface irregularities ground smooth as required.

Stripe coating shall be required to all subsequent coats including the

primer, and shall be applied by brush to physically wet in the

substrate, particularly the weld seam.

6.2.8 Site Preparation of Shop Primed Surfaces

Site preparation shall first consist of thoroughly degreasing followed

by the cleaning method as described in section 6.2.2 to remove all

loose shop priming paint and to prepare the surface to the condition

specified. Temporary/holding primers shall be completely removed

and re-worked in accordance with the paint schedules prior to

installation on site.

6.2.9 Agreed Standard of Surface Preparation

For blast cleaned surfaces the contractor shall use the colour

photographic standards as ISO-8501-1, 05 5900/BS 7079 (1988).

For power tool and hand tool cleaning the contractor shall use the

colour photographic standards for hand cleaning ISO 8501-1: 1988 05

5900/BS 7079 (1988) Part-1.




6.2.10 Surface Profile

‘

The surface profile after blast cleaning shall have a min/max height of

50/75 microns for carbon steel and a min/max height of 30/50 microns

for stainless steel (as measured by surface replica technique -

TESTEX).

6.2.11 Rogue Peaks

These may be defined as peaks of exceptional height in the blast-

cleaned surface, which may not be indicated by the normal methods

of surface profile measurement.

The presence of rogue peaks may be demonstrated by:

Viewing the surface through an illuminated magnifier.

Rubbing lightly over the surface with a clean cotton glove. Care

must be taken to ensure that no cotton fibers remain on the steel.

The presence of ‘rash rusting’ on the primed surface, due to the

peaks not being coated with primer.

If rogue peaks are found, they may be removed by lightly

scuffing the surface with emery paper, a metal bar or, preferably,

by hand. It is essential to check that all dust and other

contamination is completely removed after the sanding operation,

also that the operation has been successful in the removal of the

rogue peaks.

6.2.12 Soluble Iron Corrosion Products (Soluble Salts)

When rusted steel has been blast-cleaned and is acceptable to a Sa3 or

equivalent visual standard, it is still probable that the surface is

contaminated with ‘soluble iron corrosion products’ (‚Soluble Salts‛).




Care shall be taken to determine the presence of ‚Soluble Salts‛ and

their adequate removal shall be in accordance with tests described in

BS 5493: 1977: Appendix G Test for detecting soluble rust producing

salts remaining on blast cleaned steel. Refer to Painting Inspection

Procedure, item 3.4.1 (Sheet 2 of 5).

6.2.13 Treatment of Mechanical Damage to Furnished Painted Items

Where the substrate has been exposed, by mechanical damage, the

area shall be re-prepared to the original standard and coated with the

specified system to restore the full film thickness. The surrounding

50mm (2 in) of sound paintwork shall be lightly blasted or abraded to

provide a firm key.

Where very small areas of such damage occur in otherwise sound

coatings, hand or power driven tools may be used to prepare the

exposed substrate.

Repainting shall completely cover the prepared surface and the

surrounding 50mm of intact paintwork.

Areas which have been damaged without exposing the substrate

shall be washed with proprietary detergent solution and rinsed with

fresh water. This shall be followed by abrading the area of damage

including the first 50 (2 in) mm of surrounding intact coating. The

relevant intermediate and finish coats as shown in the painting

schedules shall then be applied in accordance with this specification.




SECTION 7

APPLICATION




7.0 Application

7.1 General

All surfaces to receive paint shall be cleaned and free from grease, salt, and

surfaces deposition and shall be thoroughly dry.

Paints shall be applied strictly in accordance with the manufacturer’s

instructions as soon as the previous coating is hard enough to receive

another coat. Delay may facilitate washing down between coats.

7.2 Weather Conditions

Paints shall only be applied when suitable weather condition prevail. Paints

shall not be applied under the following conditions or when such conditions

are likely to prevail before the paint is hard:-

(a) At temperature below 5°C or when the temperature is likely to fall

below this value before the surface film is dry or on surfaces

registering low temperature.

(b) When the relative humidity of the atmosphere exceeds 85 %.

(c) The steel temperature is less than 3°C above the dew point.

(d) During foggy or misty conditions.

(e) Before dew or moisture has evaporated.

(f) When it is raining or rain is imminent.

(g) Excessive elevated steel temperature shall be governed by

Manufactures parameters, data sheets etc.

7.3 Preparation of paint

Skins shall be completely removed from the container and the paint shall be

stirred until it is of homogenous consistency.




No hand stirring of paint is allowed for quantities in excess of 5 liters.

Before use, paint shall be allowed to stand for a time long enough to remove

aeration caused by stirring.

7.4 Method of Application

The method used to apply the paint shall be compatible with the type of

paint and the surface to be covered, in order to obtain film of even

thickness, free from any sag, runs or pin holes, holidays, and any other form

of discontinuity.

Standard method of application shall be airless spray unless specified,

application by rollers, brush or conventional spray shall be by ‚Company‛

approval. Due care shall be exercised to prevent overspray and

contamination of other surfaces by the use of shields, etc.

Brush application shall be limited to stripe coating and small local areas for

touch up. Under no circumstances shall zinc or aluminium in the form of

paint pigments or metal spray be allowed to come into contact with stainless

steels, nickel based alloys or copper based alloys.

7.5 Film Thickness

Due care shall be paid to the solids content of the paint when deciding upon

the wet film thickness to be used in order to arrive at the specified dry film

thickness, in general guidance from the manufacturers data sheets and SSPC

- PA2 Measurement of Dry Paint Thickness (with Magnetic Gauges). Steel

Structures Painting Council.

7.6 Priming

The priming coat shall be applied as soon as possible after the surface

specified standard has occurred. Irrespective of this, the following

maximum time limits are required.

(a) Blast cleaned surfaces, shop and site, within 4 hours.




(b) Power tool and hand tool cleaned surfaces, within 12 hours.

7.7 Over coating

Where possible the subsequent application shall be applied over the

priming paint as soon as the primer is dry and hard enough to receive the

next coating and in general guidance from Manufacturers data sheets.

Before application of the next coating the contractor shall ensure that the

previous coating is thoroughly dry and clean from all harmful matter, such

as grease, oil, dust, etc. Swab samples of the surface may be taken at the

discretion of ‚Company‛.

7.8 Contrasting Colours

Where it is necessary to apply more than one coat of a particular

paint to obtain a specified dry film thickness, then the first coat shall

be selected sufficiently different in colour, in order to distinguish

from the next and subsequent coats.

7.9 Bolted connections

Shop bolted connections shall be prime coated and brought together

whilst the paint is still wet. Bolted connections using high strength

friction grip bolts shall not be painted and the contractor shall ensure

that all surfaces for these bolts are adequately masked off before

painting. The size of masking shall be a minimum of 25mm greater

than the connected surface.

7.10 Stripe Coating

Stripe coating shall be required to all welds, bolts, nuts, angles and

sharp edges to all subsequent coats including the primer prior to

spray coat application to maintain dry film build.

7.11 Cold Applied Tape

Cold Applied tape wrappings shall be applied in full accordance with

the manufacturer’s recommendations.




Tape wrapping shall be applied over the compatible primer coat in a

continuous overlapping spiral with a minimum overlap of 50% and

with sufficient tension to provide good adhesion without wrinkling

or necking of the plastic carrier. The tape shall begin and terminate

in a square end, such that all of the substrate is covered by a double

thickness of tape. The tape shall be applied in such a manner that it

does not bridge discontinuities in the surface of the substrate. Where,

surface discontinuities cannot be accommodated by the tape without

bridging, and then the surface shall be profiled with compatible

moulding putty, before tape application. The moulding putty shall

be specifically formulated for this purpose and obtained from the

same manufacturer as the tape.

Where piping emerges from the ground the tape wrapping shall

extend 18‛ (450mm) above ground and overlap the above ground

painting system by a minimum of 4‛ (100mm). Finish shall be Off-

white or Light Grey for U.V. resistance.

7.12 Internal Lining of Tanks and Vessels

General

vessels, including heat exchanger water boxes and channels etc., shall

be in accordance with the painting schemes shown in SCHEDULE ‘C’

of this specification.

The methods of surface preparation and coating application shall be

as described in section 6 & 7 except as amended below.

All removable fittings shall be prepared and coated outside the vessel

or tank and reinstalled once the internal lining has fully cured.

Contractor’s personnel shall take care to avoid damage to the applied

coating and all wear clean overshoes when working inside the vessel

or tank.




7.13 Surface Preparation

Surface preparation shall include the removal of all rough weld

capping and surface laminations, and profiling of all sharp edges,

corners etc. followed by dry abrasive blasting to the standard in

SCHEDULE ‘C’.

7.14 Extent of Coating

The lining shall extend over the total internal surface including the

bore of nozzles and over the faces of all flanges, unless the latter are

weld overlaid with corrosion resistant alloy (CRA), in which case the

lining shall terminate on the CRA. To ensure correct sealing, glass

flake coatings on flange faces shall be press moulded or machined

that after fully curing.

Where sacrificial anodes are installed, care shall be taken to minimize

damage to the coating at the attachment points and to ensure that the

active surfaces of the anodes are not coated.

The lining shall be inspected for any irregularities such as raised

areas, pinholes, soft spots, disbandment, discontinuities and

delaminations. The final inspection shall include electrical

discontinuity testing over 100% of the coated surface in accordance

with NACE RP-0188-90. All indicated coating holidays shall be

thoroughly investigated and all defective coating removed and

replaced fully in accordance with the requirements of this

specification. The electrical discontinuity test shall be repeated over

all repaired areas.

7.15 Repairs to Glass Flake Linings
