PART 1 GENERAL

1.1 SECTION INCLUDES

A. Work included under this Section shall consist of furnishing all materials and equipment and performance of all labor necessary to paint exterior and interior steel tank surfaces as outlined in this Section.

B. Paint Manufacturer shall certify that their product is appropriate for the intended use.

C. Paint manufacturer shall certify that the painting contractor is qualified in the application of their paint products for the intended use.

1.2 PAINTING INCLUDED

A. The work includes painting and finishing of interior and exterior exposed items and surfaces throughout the project, except as otherwise specified. Surface preparation, priming and coats of paint specified under this Section are in addition to shop-prim-ing and surface treatment specified under other Sections, except as otherwise specified.

B. The work includes field painting of all bare and covered pipes and ducts (including color coding), and of hangers, exposed steel and iron work, and primed metal surfaces of equipment installed under the mechanical and electrical work, except as otherwise specified.

C. "Paint", as used herein, means all coating systems materials, including primers, emulsions, enamels, sealers and fillers, and other applied materials whether used as prime, intermediate or finish coats.

Paint all exposed surfaces whether or not colors are designated in "schedules", except where the natural finish of the material is obviously intended or specifically noted as a surface not to be painted. Where items or surfaces are not specifically mentioned, paint these the same as adjacent similar materials or areas. If color or finish is not designated, the Engineer will select these from standard colors available for the materials systems as specified.

1.3 PAINTING NOT INCLUDED

A. The following categories of work are not included as part of the painter-applied finish work, or are included in other Sections of these Specifications, unless other-wise shown or specified.

1. Shop Priming: Unless otherwise specified, shop priming of ferrous and other metal items is included under the various Sections for structural steel, miscellaneous metal, hollow metal work, and similar items. Also, for fabricated components such as wood casework, and shop-fabricated or factory-built mechanical and electrical equipment or accessories.

2. Pre-Finished Items: Unless otherwise indicated, do not include painting when factory-finishing or installer-finishing is specified for such items as (but not limited to) metal toilet enclosures, acoustic materials, pre-finished woodwork and casework, finished mechanical and electrical equipment including light fixtures, switchgear and distribution cabinets, doors and equipment.

3. Concealed Surfaces: Unless otherwise indicated, painting is not required on surfaces such as walls or ceilings in concealed areas and inaccessible areas, foundation spaces, furred areas, utility tunnels, pipe spaces, and duct shafts.

Paint all piping, equipment, and other such items in concealed spaces, unless otherwise indicated.

4. Finished Metal Surfaces: Metal surfaces of aluminum, stainless steel, chromium plate, copper, bronze and similar finished materials will not require finish painting, except as otherwise indicated.

5. Operating Parts and Labels: Do not paint any moving parts of operating units, mechanical and electrical parts, such as valve and damper operators, linkages, sensing devices, motor and fan shafts, unless otherwise indicated. Do not paint over any code-required labels, such as Underwriters' Laboratories and Factory

Mutual, or any equipment identification, performance rating, name, or nomenclature plates.

PART 3 EXECUTION

3.1 PAINTING

A. The Contractor shall comply with all health and safety regulations and requirements of OSHA (or State Health and Safety Regulatory Agency), SSPC-PA

Guide 3, and the paint and abrasive manufacturers.

B. The roof vent, safety climbing devices, and any other non-painted items shall be removed prior to cleaning and painting.

C. Paint shall not be applied on damp or frosty surfaces, nor during wet, foggy, or weather below 50º F, or above 85% relative humidity. Comply with manufacturer’s product data as to environmental conditions. Surfaces to be painted shall be made free of dust and other foreign matter before paint is applied; surfaces shall be completely dry before paint is applied. Iron and steel which have been shop primed, shall have all abrasions in the priming coat cleaned to bright metal to remove all scale, ridges, rust, and faults in the prime coat. Weld splatter shall be removed and that area re-primed. Voids and open and hollow places, shall be repaired with a material compatible with the surface to be repaired.

D. Paint shall be spread and brushed out so that there shall be no drops, runs, or sags in the coating. Where runs, sags, and drops do occur, they shall be removed and the surface shall be re-coated. Paint shall be dry before additional coats are applied.

Drop cloths shall be used to protect surfaces of the structure and equipment in place, and upon completion of work, paint spots shall be removed from surfaces and defaced surfaces shall be re-finished. Painting found to be defective, and that applied under adverse conditions, shall be removed and new paint shall be applied.

Where more than one coat is required, undercoats shall be job-tinted.

3.2 ENVIRONMENTAL PROTECTION

A. Provide environmental protections to prevent damage to persons or properties exterior to the work site during all cleaning operations that create dust or mists.
