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.

PROTECTIVE COATINGS SPECIFICATION
FOR EQUIPMENTS, PIPING & STRUCTURES
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.

PROTECTIVE COATINGS SPECIFICATION
FOR EQUIPMENTS, PIPING & STRUCTURES
(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‛).
