1 GENERAL

This specification generally covers surface protections against corrosion and defines the

minimum requirements for surface preparation/treatment, protective coatings and painting for

structural steel, iron works, metal and other non-metallic surfaces.

The following shall be applicable and shall be considered:

a) All metallic parts (except stainless steel parts) used inside closed rooms shall be painted or

galvanised.

b) All metallic parts used outdoor shall be galvanized and painted.

c) Zink and paints and related protection material shall be in accordance with the latest

international standards as a minimum requirement, and shall comply with the requirements of

proper health, safety, and environmental conditions.

d) Equipment to be used for performing the required galvanizing or painting, should be

equivalent to the equipment recommended by the paint manufacturer and should be suitable

to apply the coating as specified.

e) Painting materials shall be delivered to locations where painting is to be carried out, in

unopened original containers, which shall bear a legible product designation, batch number,

date of manufacture and expiry date. The date of manufacture must not be before the date of

paint system approval.

f) Only complete paint kits shall be mixed. No partial kits will be accepted. Surplus Paint in

Pots of expired mixed material must not be used after the expiry date of these materials.

g) The painting material shall be handled and stored in accordance with the paint

manufacturers latest published instructions and shall be protected against damage, moisture,

direct sunlight and temperatures.h) Storage temperature of paint shall range between 5oC and 35oC.

i) Compressed air used for cleaning, surface preparation (abrasive blasting) and application

shall be free of oil and moisture.

j) Blasting material shall be clean and free from oil or contaminants. The particle size shall be

capable of achieving specified surface profile.

1.1 Site Conditions

For site requirements, reference shall be made to the Standard Technical Specification, Part:
