GENERAL REQUIREMENTS
INTENT
OF SPECIFICATION
The intent of requirements of this specification for field painting is
to ensure thorough and proper surface preparation, and careful and complete
paint application to all exposed areas of surfaces specified to be field
painted in this specification, and observing strictly the following procedure :
As the works will be located in a tropical area and near the sea, the
paint shall be of a type which can best resist tropical conditions and salty
air environment.
The Contractor shall thoroughly clean, prime coat where required and/or
touch up the entire work, or a substantial portion thereof, before starting the
intermediate coat of paint. However, work shall proceed in a pattern that will
keep to a minimum the necessity for re-cleaning the touch-up work already done
or the intermediate coat already applied. Cleaning shall be done in such a
manner as not to liberate dust and shall be approved by the Owner. No
intermediate coats shall be applied until the cleaning, prime coating and/or
touch-up work has been approved by the Owner.
After intermediate coat has been applied, no finish coat shall be
applied until the intermediate coat is complete, inspected and approved by the
Owner. If any succeeding coat is applied before approval of the undercoat it
will be assumed that such undercoat has not been applied and at the option of
the Owner such undercoat shall be reapplied or the entry coating shall be
removed and this area repainted from the beginning.
DEFINITIONS
Contact Surfaces: Surfaces which are permanently in contact with other
surfaces of the same material after shop assembly or field erection. (i.e.
surfaces under column and beam cover plated, faying surfaces under connecting
angles, splice plates, bolts, nuts and washers).
Inaccessible
Surfaces: Surfaces which are made inaccessible for painting (other than Contact
Surfaces) after shop fabrication or field erection such as facing surfaces in
an assembly composed of two angles back to back with a gusset plate between
them.
DFT:
Dry film thickness expressed in microns.
Outdoor
: Areas of the power plant with or without roofs but without any wall.
Indoor
: Areas of the power plant enclosed with complete roof and walls.
SAFETY REQUIREMENTS
Ail safety measures and precautions required by the Owner and safety
recommendations of materials manufacturers, suppliers, etc. shall be carefully
complied with during the entire course of the Work.
PAINT
Paint
Manufacturers Instructions: The manufacturer of the paints for the selected

1/2 of SSPC-Vis-1.
SURFACE PREPARATION FOR CONCRETE AND PLASTER SURFACES
Concrete and plaster surfaces shall have aged at least 60 days prior to
starting preparation for painting.
Surfaces shall be completely free of oil, grease, free lime or other
contaminants.
Cracks, voids, etc shall be filled with speckling compound and sanded or
rubbed smooth,
All rough spots shall be sanded smooth.

Surfaces shall be sanded smooth
All knots and sappy streaks shall be carefully coated with shellac
before painting.
Suitable
primer shall be used.
Holes, splits, scratches etc. shall be filled with speckling compound
after primer has been applied and the affected areas again sanded smooth.
SURFACE PREPARATION FOR GALVANIZED SURFACES
Surface shall first be prepared by Solvent Cleaning.
Following the solvent cleaning, the surface shall receive one (1) wash
coat pre-treatment in accordance with the applicable requirements of SSPC
Pre-treatment Specification No. 3, "Basic Zinc Chromate-Vinyl Butyral Wash
coat", or shall receive a prime coat as specified.
METAL PATCHING
If
it is found necessary to patch or fill scratches or gouges in equipment metal
housing or motors, etc., a metal putty shall be used. Metal putty shall be

points where pipes branch or pass through walls, floors or partitions.
Colour
of the bare and jacketed pipes shall be as indicated in Table 4.4.2.22-3 as
applicable.
The final location of colour bands, arrow marks
and names shall be adjusted at site according to the direction of the Engineer,

indicated.
RESTRICTIONS DURING
PAINTING
Application of paint shall conform to the applicable requirements of
SSPC Paint Application Specification No. 1, "Shop, Field and Maintenance
Painting" and to the requirements herein specified.
Paint shall not be applied to surfaces which are at a temperature of
over 500C unless the paint is specifically formulated for
application at the proposed temperature. When a surface is painted in hot
weather, precautions shall be taken to ensure that the specified dry micron
thickness of paint is obtained.
MOISTURE AND
HUMIDITY RESTRICTIONS
Paint shall not be applied in rain, fog or mist or when the relative
humidity is such as to cause
condensation on metal surfaces due to variation in metal temperatures and
surrounding air temperatures.
All surfaces shall be
perfectly dry before and while being painted.
METHOD OF APPLICATION
Application of the paint shall primarily be made with proper size and
grade of brushes except where spray equipment or rollers can be used to
advantage.
Spray
equipment, if used, shall be accurately and fully controlled at all times so as
to prevent damage to adjacent surfaces. If, in the opinion of the Owner, the
over spray during paint spraying operations is causing damage to plant
equipment the use of spray equipment will be restricted to those areas (if any)

acetone and examining the surface with a 10 power magnifying glass to observe
the absence or presence of rust under the prime coat. The presence of rust or rust stains under
such swatches shall be sufficient cause for rejecting the Work, and The
Contractor shall prepare and recoat the work in the field at his own expense.
Dry and wet film thickness may be determined by the use of gauges. The gauges and procedure shall be in
accordance with SSPC PA-2.
To check the amount of thinner added the viscosity of paints in the cans
