attachment of cathodic protection leads to structures, where this is applicable;

At the start of each shift and after warm up of the compressor equipment, the compressed air

shall be tested in accordance with ASTM D4285 to ensure that it is free from oil and moisture

contamination.

Environmental conditions are acceptable for surface preparation and will remain so for the

expected duration of the activity. Surface preparation and coating operations shall not be

undertaken:

Appropriate measures shall be in place to protect surfaces exempt from coating or finish

coated surfaces from damage, ingress of abrasive or dust from blast cleaning.

Temporary protective coatings applied for transport and/or storage have been completely

removed.

must be reported to the Client for evaluation and sentence.

Surface defects such as cracks or laminations in the substrate must be reported to the Client

for evaluation and sentence.

Metallic surfaces shall be prepared using only dry abrasive blast cleaning techniques in

accordance with AS1627.0 and AS1627.4, for the coating to be applied and be:

application of the full coat.

Mixing of coatings shall be done in clean containers which are free from foreign matter, to the correct

ratios, and in the specified order in accordance with the coating manufacturer’s recommendations.

Thinning of coatings shall ensure that the VOC levels do not exceed those specified by the coating

manufacturer’s recommendations. All thinning operations shall be done in accordance with the

coating manufacturer’s recommendations.

Primers / 1st coat should be applied as soon as possible post preparation (maximum of 4 hours) to

prevent flash rusting or other forms of contamination of the surface.

Primer shall not be applied within 50 mm of field welds or within 100 mm of un-prepared surfaces.

Primers of inorganic zinc shall be continuously agitated during coating application.

detachable metal labels.

For permanent identification on structural steelwork only, figures shall be heavily punched or

embossed by the fabricator.

3.3 Repairs

Marking of defects for repair shall be done with a marker that is not detrimental to the particular

coating or substrate being coated.

Where the surface preparation fails to meet the specified requirements, the area shall re-prepared

since the last acceptable inspection and re-inspected in accordance with section 3.1.

5 QUALITY CONTROL

5.1 General

All works shall be performed in accordance with the approved MPS and ITP to ensure that all design,

materials procurement, surface preparation, coating application, inspection, and transport, handling

and storage are adequately controlled to ensure these do not affect the performance and quality of

the finished protective coating system.

The supplier shall provide a schedule of coating operations at least two weeks prior to the

commencement of such works, so as to allow for arrangement of witness and inspection activities.

The client shall be given at least 48 hrs. notice of any changes to this schedule.

All equipment, materials, works and associated documentation shall be available and accessible at

any time during a witness or inspection activity.

All testing equipment shall have valid certification and be regularly checked for the duration of testing

activities.

At the start of each shift and after warm up of the compressor equipment, the compressed air shall be

tested in accordance with ASTM D4285 to ensure that it is free from oil and moisture contamination.

The equipment shall not be used until tests indicate that there is no contamination. Where tests after

application indicate contamination, the affected area shall be repaired in accordance with Section 3.3

of this specification.

Surface preparation test panels shall be prepared at the start of each coating job, to verify compliance

with the blast profile / roughness and cleanliness requirements of the coating system proposed.

Where recycling of non-expendable abrasives is proposed, the abrasives shall be tested for the

presence of contamination before and after each shift. Contaminations found prior to use shall be

discarded.

Contamination found after the commencement of cleaning shall have the entire area since the last

successful test repaired in accordance with Section 3.3 of this specification.

Adhesion checks shall be performed on suspected areas in accordance with AS 3894.9.

All coating activities are to be supervised and inspected by an experienced and competent coatings

inspector, certified in accordance with an internationally recognised scheme (minimum NACE 2-3, or

FROSIO Red).

5.2 Surface Preparation Inspection

All prepared surfaces shall be inspected to verify that the specified level of cleanliness and surface

profile has been met including but not limited to:





Visual inspection for cleanliness of metallic substrates over 100% of the cleaned surface in

accordance with the pictorial standards of AS 1627 or ISO 8501-1.

Inspection of the surface profile of metallic substrates in accordance with AS 1627 or ISO

8503 after each replenishment of abrasive, based on an inspection frequency of once per

10m2 area.

5.3 Protective Coating Inspection

Each coat and the completed system shall be inspected to verify its acceptability including but not

limited to:

Visual inspection over 100% of the surface area of each coat for surface flaws that will affect

the integrity of the coating e.g. sags, over spray, mud cracks, pin holes, blistering loss of

adhesion or any other defect.

Inspection for the following, based on an inspection frequency of once per 10m2 per reference

area:

o Coating adhesion of the fully cured system in accordance with AS 3894.9 or ISO

2409 and 4624 (as appropriate to the DFT). Where lack of adhesion is suspected as

a result of the visual inspection - values less than 80% of those recorded during the

coating procedure qualification are unacceptable;

o DFT in accordance with AS 3894 or ISO 2808 or ISO 19840 using a calibrated dry

film thickness gauge - values less than 95% of the minimum DFT are not acceptable;

o Visual inspection over 100% of the surface of galvanised items. The zinc coating

shall be free of voids, blisters, flux spots, inclusions, dross, acid, or black spots. The

coating shall be adherent so it will not be removed by any reasonable process of

handling or erection;

o Lumps, globules, or heavy deposits of zinc which will interfere with the intended use

of the material / article will not be permitted;

o The mass of galvanised coating shall comply generally with the requirements in

Appendix 4 of this specification and the applicable requirements of AS 4680/ISO

1461;

o All unacceptable flaws in a coating system shall be recorded and repaired in

accordance with Section 3.3 of this specification and using zinc rich epoxy coating.
