5. PROCEDURE
5.1 General
The procedures, conditions and precautions to be followed in preparing the surface painting,
in handling paints, and in applying paint to the prepared surface shall be in accordance with
this procedure.
Only thinners of the type recommended by the paint VENDOR shall be used.
Precautions shall be taken to prevent paint from being applied to name plates, couplings,
shafts, other finishaed surfaces such as valve stems, adjustment painted surfaces of the
interior of equipment. Any paint spots or streaks which may have formed shall be removed
immediately.
Paint surfaces shall not be handled until the paint has dried throughy expect when the coating
is to be heat-cured. Paint film damaged by handling or by other means shall be scraped off
and touched up with the same numbers of coates and same types of paint as previously
applied. For steel or iron surfaces, if the prime coat has been damaged, the paint films shall be
removed entirely from the effected area, the surface cleaned and be repainted.
On completion of the work, all paints cans, cloths, blasting abrasives, equipment, etc. shall be
removed from the work site and disposed as directed by CONTRACTOR.
The color specimen shall be made by the same method as the actual paint work, except
painting interval.
Zinc painted or galvanized components shall not be painted to stainless steel surfaces. Zink
overspray shall not be permitted to settle on stainless steel surfaces.
Painting shall preferably be carried out inside workshops with proper facilities. When this is
not possible and field painting is necessary, then proper sheltering must be provided against
sand and dust. The work to be painted shall be kept 1 meter above ground on stands.

5.2 Surface Preparation
All steel surfaces shall be thoroughly cleaned prior to painting of any material to avoid
premature failure of the painting coating. The method of surface cleaning or preparation shall
be one of , or a combination of the following:
a) Blast Cleaning
b) Power Tool Cleaning
c) Hand Tool Cleaning
d) Solvent Cleaning
e) Pickling
All crevices, corners and edges of shape steel, joint of steel plates, especially around bolt
heads, weld beads, etc. shall be cleaned with special care.
Sharp edges shall be rounded.
All cleaned surfaces shall be primed in the same day when cleaning is performed. Cleaned
surfaces left unpainted for one night or on which rain fall or dust has settled shall be recleaned before priming.
Compressed air supply used for blasting shall be free from water and oil. Suitable air filters,
separators and traps shall be provided and installed in the coolest part of the system.
Cleaning of contaminated surfaces shall be done immediately before application of paint in
such manner that adjacent wet paint surfaces are not marred by the cleaning operation.
Power tool cleaning, may be used on areas where it is difficult to blast clean as follows:
a) Welding areas of pipe in field
b) Narrow areas where the blast nozzle cannot be inserted.
c) Surface preparation for repair painting
The abrasive must be dry, clean and free from contaminant.
Purity and acceptability of abrasive blast cleaning quality shall be judged on the basis of
visual examination using pictorial standard in accordance with BS 7079 Pt:A1/ISO 8501-1.
At the commencement of the work, sample metal panels shall be prepared to demonstrate the
ability to comply with the specified level of cleanliness and, after approval, shall be.
5.3 Preparation for Paint
Paints which are supplied as two or more components in separate containers shall be mixed
together immediately before use in the proper ratio and applied within the specified time in
accordance with VENDOR’s recommendations.
Paint shall be thoroughly mixed immediately before application. Mixing of quantities of 5
gallons or more shall be done by power stirrers, paddle mixers, can vibrators, or can shakers.
If the quantities are less than 5 gallons, mixing by hand is acceptable.
Thinner shall be added strictly in accordance with paints VENDOR’s standards.

5.4 Application
Paint materials shall be applied by the VENDOR’s recommended method. Care shall be taken
to select paint materials to suit the intended application method. The VENDOR’s instructions
shall be strictly observed regarding the followings:
a) Type and maximum quantities of thinner, if any, that can be used.
b) The correct method of application.
c) The required blast profile on the prepared surfaces.
d) The required ambient condition.
e) The mixing proportions of two-pack materials.
f) The pot life of two-pack materials.
g) The minimum time before over coating
h) The minimum time, if any, to over coating for proper adhesion between coats
i) The compatibility of different coats.
j) The storage conditions for the paint.
The paint shall be applied evenly to produce a smooth coating of the required uniform
thickness without sags, runs, spots, damage or contamination.
After surface preparation the bare metal surface should be primed as soon as possible. When
the prepared surfaces unavoidably need to be left for a longer time, e.g., overnight, they shall
be inspected before applying primer and, if necessary prepared again.
Unless special protection is provided, paint shall not be applied in rainy, damp, windy, or
dusty weather, or when such unfavorable weather is predicted.
Finished painted surfaces shall be uniform and smooth.
Dry film thickness (DFT) shall be measured by oleometer or micro tester dry film gauges.
DFT measurement shall be made of each coat and of the total system. If the minimum dry
film thickness has not been met, additional coat or coats shall be applied until the minimum
dry film thickness is attained.
Paint shall be applied by one, or a combination of the following method:
a) Brushing
b) Roller Coating
c) Air-spraying

Paint shall not be applied on surfaces when:
a) The surrounding atmospheric temperature is below 5 oC or above 40oC.
September 2012- Painting HSE Procedure
Page 6

b) The relative humidity is above 85%
c) The wind velocity is in excess of 7m/s (Dust and dirt may be deposited in the wet paint
film, or it will interfere with spray painting)
d) The surface temperature is less than 3 oC above the dew point or in excess of 38 oC.
Equipment and/or piping shall not be painted until approved heat treatment, non-destructive
testing, and pressure testing has been completed unless otherwise approved by POGC.
5.5 Repairs
During painting, adjacent surfaces shall be protected from paint splashes and other blemishes.
If blemishes of damaged should be occur, they should be cleaned or repaired in agreement
with POGC.
Regardless of the surface preparation , hand tool cleaning and/or power tool cleaning method
may be used for the surface preparation followed by repair (touch-up) paint, provided that the
surfaces are limited to small and minor areas. The paint system for repair (touch-up) paint
shall be used same as original paint system as per the specification.
5.6 Precaution
“Wet Paint” signs shall be posted around the area where readily visible, until the paint has

“No Smoking” and other warning signs, such as “Caution”, “No Open Flame”, etc. shall be
posted all areas where and while painting is being performed. The signs shall be remain
posted for a sufficient time after painting has been completed.
When painting work is performed in a small area, adequate ventilation shall be provided to
reduce the concentration of harmful vapors in the atmosphere. Workmen shall be required to
wear vapor proof masks, etc. for protection when working in poorly ventilated places.
Certain paint materials such as zinc chromate, hot coal tar enamel, benzene etc, are identified
as carcinogen. Proper personal protective gear such as air line hoods, respirator, chemical
cartridge, etc. shall be worn.
Sandblast nozzle shall be equipped with remote control shut off the “dead man” variety to
reduce the hazard of injury to nearly workmen if the hose dropped. The blast nozzle shall be

oldest paint of each kind shall be used first. Not be used if it has gelled, or if it has thickened
to such extent that more than 5% by volume (10% by volume for priming paints) of the
correct thinners is required to bring it to brushing consistency.
All containers of paint shall be clearly marked or labeled to show paint identification, date of
manufacturer, batch number order number, and special instructions, all legible at the time of
