GENERAL REQUIREMENTS

This specification defines the technical requirements for painting, surface preparation, as well as the application of protective coatings for structural steel, equipment, piping, tanks, etc. for the entire plant.
After the Contract has been awarded, the contractor shall submit immediately the name of the proposed coating supplier and applicator together with a painting and coating schedule and with a quality assurance program for approval.
The following standards with their last edition are guiding this specification:
-           Swedish Standard SIS 055900
-           ASTM D 2200
-           SSPC (Steel Structures' Painting Council) - Standards
-           DIN

The Company/Engineer shall, at all times, have access to the works in order to inspect surface preparation or application of work in progress in the manufacturer/contractor workshop as well as on-site.

Should any work or product be found to be defective or not in compliance with the specification, correction or replacement shall be made by the Contractor at his costs.

The Contractor shall bear the full responsibility for the application of coatings, applied by him on surfaces, primed or painted by others.

Covers should be used where required to protect building structures, equipment, insulation, and lagging. When surfaces have been stained or otherwise damaged by the painting and/or surface preparation work, the Contractor is responsible for thoroughly clean and/or repair these surfaces.

Scaffolding shall be erected, maintained, and dismantled without damage to equipment, piping, machinery, or structures.

Parts that cannot be coated and which are very sensitive to atmospheric exposure must be efficiently packed for storage. The inside of equipment and machinery shall be cleaned thoroughly at works, and before transportation, all holes and access openings shall be efficiently sealed in order to prevent infiltration of dirt and humidity.

Treated and machined parts not to be painted shall receive provisional corrosion protection.
Unless otherwise specifically indicated, surfaces, such as stainless steel, brass, copper, or any other non-ferrous items, finished hardware, aluminum windows, etc. shall not be painted.

Note:
Structural bolts shall be galvanized, raised, or cadmium-plated and painted as specified underpainting systems for carbon steel surfaces.
