SECTION 6

SURFACE PREPARATION






6. SURFACE PREPARATION6.1 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/pipework.

(b) Pickling by either Sulphuric Acid or Phosphoric Acid strictly inaccordance 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 vendors 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 a 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) 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

pipework.

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.

(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 millscale, 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 paintSurface 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

blastcleaned 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 fibres 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 an 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.

10.0 INSPECTION AND TESTING

All surface finishes and painting shall be inspected by an ‚COMPANY‛ approved

painting inspector for workmanship in accordance with the approved Quality

Plan and ‚COMPANY‛ Internal Paint Inspection Procedure Ref. Painting

Inspection SOP.023, Issue 1 Rev 1 as issued to all contractors in the pre-tender

documents.

Any work rejected due to poor workmanship or incorrect application of the

coating shall be corrected by remedial action as directed by ‚COMPANY‛ issuedN.C.R. (Non Conference Report).

All finished dry film thickness shall be tested by use of an Magnetic Dry Film

Thickness Gauges (Types 1 & 2) on both ferrous and non-ferrous surfaces to

determine the required total dry film thickness, and shall be in accordance with

S.S.P.C. Steel Structures Painting Council PA-No.2. "Measurement of Dry Paint

Thickness".

Calibration of the Magnetic film thickness gauge's shall be carried out, inaccordance with the above, on the job site and agreed between the inspector and

contractor. Any layer or total system which does not meet the required dry film

thickness specified shall be brought to the required thickness using the material of

the last coat applied.

All the previous clauses of the specification will be applied at all times during the

painting preparation and application.

It is the Contractors responsibility first and foremost to maintain QA/QC toADGAS requirements as mentioned in Section 4.

Contractors Responsibilities - Pages 2, 3 and 4 of 4.

Furthermore, all inspection and testing requirements to be undertaken by the

inspection authority of ADGAS in both qualitative and quantitative tests,

including Non-destructive and destructive testing, is given in the ADGAS S.O.P.-
