Brush application ("stripe coating") shall be used to ensure adequate film
thickness at corners, edges, bolts, nuts and welds.
Roller application shall only be allowed on steel floors and panels inside climate
controlled areas. Rollers shall be of good quality to ensure uniformity of the
applied coating.
8.5 Overcoating Method
Coatings shall be dried and cured in accordance with the Manufacturer’s
recommendations prior to over-coating. Over-runs, drips and smears shall be
removed and any coating damage or imperfection shall be repaired before over-
coating. If the DFT does not meet the requirements of this specification,
corrective action shall be taken.
Where zinc rich primers are applied they shall be over-coated as soon as
possible but only after sufficient cure if the primer is an inorganic zinc primer.
The Manufacturer’s maximum over-coating times shall not be exceeded.
Zinc salts (white rust) that have formed during the intervening period shall be
removed in accordance with the Manufacturer's instructions prior to over-
coating.
8.6 Environmental Conditions
Coating work shall not take place during the following conditions:
Under adverse weather conditions, e.g. rain, fog, snow or when such
conditions are likely before the coating has become dry;
When the ambient temperature is below 10 °C, unless approved by
COMPANY;
When the ambient temperature is above 40 °C;
When the relative humidity is > 85 %;
When metal surface temperature is < 3 °C above the ambient dew point
(< 5 °C for sprayed aluminium);
Outside daylight hours on exterior locations.
Unless otherwise agreed, the CONTRACTOR shall supply all the weather
protection, scaffolding and any other equipment necessary to ensure that the
work is carried out in accordance with this specification and the agreed
programme. This includes, for example, heating and air-drying equipment.

(Ref. 32). Higher substrate temperatures shall only be accepted if the
Manufacturer has confirmed in writing that this application will not affect the
performance of the coating work.
8.7 Holding Primers
A holding or temporary protective primer may be applied to prepared metal
surfaces to facilitate shop or site handling procedures. Such primers shall in no
way replace the function or film thickness of any part of the specified coating
system. Overcoating of zinc epoxy or acrylic based holding primers will not be
permitted by the COMPANY. These primers shall be completely removed by blast
cleaning prior to application of specified primer / first coat. Sweep blasting of
inorganic zinc shop primers may be allowed where CONTRACTOR can
demonstrate to COMPANY'S satisfaction, by submission of supporting test data
based on long term cyclic testing, that there is no reduction in system adhesion
or performance. CONTRACTOR shall also demonstrate that sufficient controls
are in place to ensure adequate cleanliness and condition of the aged primer
before overcoating.
Alternative surface cleaning is only acceptable after written approval of the
COMPANY.
In all cases, areas of localised breakdown, and weld areas or damaged areas
shall be cleaned to the full specified standard.
In areas where cathodic protection will be applied, the full coating system
including the holding primer shall be tested for cathodic disbondment in
accordance with ASTM G8 (Ref. 8) or ASTM G42 (Ref. 9).
8.8 Coating thickness
The coating systems are detailed in Annex A "Coating Systems Summary Sheets"
and the nominal dry film thickness (DFT) is given for each coat. The DFT of any
coat shall not be greater than 40 % above nor 10 % below the nominal value
specified. The exception to this is for Thermally Sprayed Aluminium (TSA) where
the minimum overall thickness shall be 200 μm. The DFT shall be measured in
accordance with SSPC-PA 2 (Ref. 33).
The minimum dry film thickness (MDFT) is the acceptance thickness for the total
applied coating system, based on a 95 % probability of this value being exceeded
by any individual measurement. In practice, this requires statistical records to
be maintained of thickness measurements.
Spot checks shall be carried out during the course of the painting operation to
ensure that film wet film thickness (WFT) is being maintained. These shall be

performed according to the procedure described in ISO 2808, Method No. 1A -
comb gauge (Ref. 34).
8.9 Multi coat systems
Sequential coats shall be contrasting colours so that each stage of the work can
be readily identified and their film thickness determined.
Intervals between coats shall be kept to the minimum complying with the
coating SUPPLIER’s recommendations at the prevailing temperature in order to
avoid contamination between coats. Any contamination between coats shall be
removed.
Zinc silicate and zinc rich epoxy primers shall be tie-coated or over-coated
within a maximum of seven (7) days unless specific approval has been given by
the COMPANY to extend this period.
In the event of specified maximum recoating intervals being exceeded, or for
the application of additional coats to existing weathered coatings, the COMPANY
shall be informed and the Manufacturer’s recommendations for surface
preparation shall be fully described. This may involve sweep blasting, or water
or solvent washing before top coating or such other measure as approved by the
COMPANY.
8.10 Weld areas
No coating, except "weldable" grades of zinc based holding primers, shall be
applied within a minimum of 50 mm or edges / areas prepared for welding. The
zinc based holding primer shall be a grade which is approved by a certifying
authority such as Lloyds Register or equivalent as not being detrimental to the
resultant weld.
The following procedure shall be followed with regard to welding, where zinc
silicate or zinc rich epoxy and tie coat are used:
Intended weld area shall be masked after blast cleaning and before priming,
as stated in Section 6.6;
After the application and curing of the primer, an additional 50 mm on each
side of the primed surface, immediately adjoining the weld area, shall be
masked. The tie coat shall be applied within the stipulated 7 days;
When ready to weld, the first tape shall be removed from the base steel
exposing the weld area;
On completion of welding, the area shall be mechanically cleaned to
remove weld contamination and debris; thereafter the remaining masking

tape shall be removed and the weld area pencil blasted, extending this to
sweep blast the 50 mm of primed surface before proceeding with priming
and coating;
Any masking tape used shall be removed as soon as possible to avoid damage
to the surface underneath.
8.11 Carbon/stainless steel joints
Where carbon steel is welded to stainless steel, the joint shall be coated with
the coating system specified for the stainless steel with a minimum overlap of
50 mm onto the carbon steel. However, the nominal dry film thickness (NDFT)
requirements for the connected carbon steel shall be applicable.
8.12 Protection of applied coatings
Applied coatings shall be adequately protected and the temperature and
humidity controlled in accordance with Manufacturer’s recommendations to
ensure that all coatings are correctly dried and cured.
8.13 Protection of coated contact points
At contact points such as where piping rests directly on a support (e.g. a saddle
or beam), there is a potential for severe corrosion. Therefore coated surfaces
which will be in contact with other surfaces shall be protected with non-
metallic inserts or shims such as Teflon straps or preformed self-adhesive shims,
usually made from fibre reinforced plastic.
Shims should have a limited contact area and high impact strength, and retain
their properties over sustained load and offshore exposure conditions. A
corrosion resistant U-bolt coated with a protective non-metallic material should
complete the pipe clamps.
Where clamps are not used, shims made from creep resistant plastic materials
such as acrylonitrile butadiene styrene (ABS) are available. These can be
adhesive bonded to the underside of the pipe.
The selected system for protection shall be agreed with the COMPANY. Such
protection shall be applied when coatings are fully cured.
8.14 Internal Coating Of Tanks, Vessels And Equipment
Internal lining requirements are given in Specification for the Internal Lining of
Vessels and Tanks, (Ref. 52).

9 REPAIRS
9.1 General
Repair of defective areas shall be accomplished in the same manner as the
original coating in regard to surface preparation prior to recoating, unless
alternative and equivalent methods are defined within this specification, or
agreed by the COMPANY.
Epoxy coatings which have aged to the point where further application may give
rise to intercoat adhesion problems, shall be sweep blasted after cleaning prior
to further coating. Approval for this work shall be obtained from the COMPANY.
9.2 Insufficient Thickness
In the event that a completely coated surface is found to have insufficient
coating thickness, this surface may, subject to specific COMPANY approval,
receive an additional coat or coats until the specific thickness is achieved. The
COMPANY may alternatively require the surface to be blast cleaned and
recoated. Surfaces to receive additional coating shall be properly cleaned of all
foreign matter or contaminants and prepared as recommended by the
Manufacturer.
9.3 Excess Thickness
In the event that a coated surface is found to have excessive thickness, it shall
be brought to COMPANY's attention who will decide on the appropriate action to
be taken. Acceptance by COMPANY of excessive thickness will be considered
only if the measured thickness is confirmed by the Manufacturer in writing as
not being detrimental to the satisfactory service life and performance of the
coating system and if testing demonstrates that there is no loss in system or
intercoat adhesion.
9.4 Film Defects
Defects such as misses, incorrect colour, gloss level and poor hiding power shall
be repaired by applying additional coating as required.
Defects such as poor finish, texture, sagging, runs, dry spray and over-spray
shall be removed by abrading the film to remove the defect and then applying
additional coating as required.
Defects such as poor adhesion, pinholes, holidays and cracking shall be
completely removed by blast cleaning to substrate and reapplying the complete
system.

Damaged areas, defects in the coating system such as over-runs, drips and
smears that have to be removed or areas with inadequate DFT shall be re-
cleaned. The re-cleaning shall carry over on to the secure surrounding coating
for not less than 250 mm all round and the edges shall be feathered (over a
width of at least 70 mm). After surface cleaning the specified coating system or
the required layers of the specified coating shall be re-applied. Any additional
coats shall blend in with the final coating on adjoining areas. Manufacturers
shall be consulted if the existing coating requires abrading before over-coating
to obtain good bonding.
9.5 Repairs To Zinc Coated Surfaces
Where repairs are required to zinc rich epoxy primer or galvanized surfaces,
either with or without topcoats, the following procedure shall be followed:
Blast clean surface using grit to preparation grade Sa 2½ in accordance with
ISO 8504-2 (Ref. 11);
Apply 70 µm DFT zinc-rich two-pack epoxy primer in two coats;
Apply topcoats as required to achieve original system thickness.
Overcoating may be permitted before complete curing of the zinc rich epoxy
provided that all volatile material has evaporated.
It shall be noted that the above procedure is for repairs only. Under no
circumstances shall this procedure be used in place of original priming to
specification or galvanized surfaces.
Surface preparation by any other method than blast cleaning shall only be
permitted with the written approval of the COMPANY.
COMPANY may require that CONTRACTOR completely removes and re-apply the
full coating system where the extent of repairs is considered to be excessive.
Inorganic zinc silicate shall not be overcoated by itself. Insufficient coating
thickness shall be reblasted and recoated.
Repair to damaged galvanizing when the extent of damage exceeds 40 mm2,
shall be subject to COMPANY approval.
