· If the relative humidity is in excess of 85%, except for Zinc Silicate up to 90%.
In case the form of a rain or relative humidity is above 90%, all painting workshop’s
doors and windows shall be shut off to prevent the entrance of outdoor moisture.
Blower fans, ventilation system shall be worked at maximum capacity to ensure the
proper work conditions. When the surface to be painted is wet or damp, but

12. Surface Preparation
Surface preparation shall be carried out in accordance with specification TF1-2R07000009.
All pipe works shall be inspected to identify any defect that may be detrimental to
provide good performance coating system.

All sharp edges shall be ground to produce a radius and all imperfections such as skip
welds, weld spatters, rough welds and delamination shall be corrected by grinding or
sanding prior to surface preparation.
Thoroughly degrease the surfaces by organic solvent wiping or other appropriate
methods to remove all trace of oil or grease in accordance with SSPC-SP1.
Surface preparation and painting shall not, unless otherwise approved by LSP and
PPC, be carried out until the applicable NDE has been carried out and verified
acceptable. FIN shall be noticed to LSP and PPC 24 hours before or 48 hours for
weekends.
The tag name shall be masked-off before surface preparation to ensure that the proper
identification is not misplaced. Proper covering for the flange serration surfaces and all
surface which don’t require painting shall be provided to protect from handling
damages and blasting.
Blast cleaning to standard SSPC-SP 10 (Near blast white cleaning) or the equivalent
standard ISO 8501-1 Sa 2.5, using only clean and dry abrasive to achieve a 30-80
microns surface profile. ISO 8501-1 pictorial standard shall be used as reference
standard in any case of dispute on surface cleanliness.
The roughness of the blasting surface is reproduced using a Replica Tape i.e.
Elcometer Press-O-Film and measured with a calibrated Thickness Gauge i.e.
Elcometer 124 in accordance with ASTM D4417. Such replica shall be retained and
attached to the daily blasting and painting report.
All blast cleaned surfaces shall be primed before visible rusting occurs or within 5
hours of the commencement of blasting. If visible re-rusting occurs then the metal
surfaces shall be slightly blasted.
All equipment and materials to be fabricated by non-ferrous materials, example:
stainless steel, galvanized, aluminum, brass, copper, plastic, protected metal (such as
rubber lining surfaces) generally shall not be painted.

In case stainless steel, galvanized surface to be coated, it shall be prepared by sweep
blasting by proper non-metallic abrasives to provide better adhesion.
Spool components, blasted and primed at painting workshop shall be fabricated and
spot repaired for field welds at temporary workshop or at shop.
Field welds repair shall be power tool cleaning to ISO 8501-1 St3 or SSPC-SP 3 or
manual spot blast cleaning to standard SSPC-SP 6 or the equivalent standard ISO
8501-1 Sa 2.

The use of grinding disc may be included to achieve the removal of tightly adhering
weld splatter, but great care shall be taken to ensure that surfaces shall not be
polished or left with a detrimental roughness.
The cleaning method undertaken shall remove all weld flux slag, fume, loose mill scale
or loose paint if present after welding and testing has been completed.
13. Paint Application
Paint application shall be in accordance with project specification TF1-2R07-000009
requirements and coating systems.
Paint material shall be thoroughly mixed immediately prior to application. Mixing shall
always be carried out using mechanical means i.e. paddle mixer. Inorganic zinc
silicate shall be continuously stirred during the application to prevent the settling of
zinc dust to bottom of container.
Paint component shall be mixed in proper ratio as supplied by the paint manufacturer
in proportional container.
Thinners shall only be added strictly in accordance with the paint manufacturer’s
instructions. The type of thinner shall comply with the paint manufacturer’s instructions.
The manufacturer’s recommended pot life shall not be exceeded. When the limit is
reached, the spray pot shall be emptied and cleaned and new material shall be mixed.
All areas, that cannot properly spray- coated such as corners, edges, welding seam,
etc.
Will be stripe-coated prior to application of specified coat.
The spray pattern shall be adjusted so that paint is deposited in uniform layers with the
correct wet film thickness.
Spray gun shall be kept perpendicular to the surface being coated at a maximum
distance of 300 mm from the surface and no closer than 200 mm to the surface.
