<br /> 4. Ferrous Metals: Clean ungalvanized ferrous-metal surfaces that have not been shop coated; remove oil,
<br /> grease, dirt, loose mill scale, and other foreign substances. Use solvent or mechanical cleaning methods that
<br /> comply with the Steel Structures Painting Council's(SSPC)recommendations.
<br /> a. Blast steel surfaces clean as recommended by paint system manufacturer and according to
<br /> requirements of SSPC-SP 10.
<br /> b. Treat bare and sandblasted or pickled clean metal with a metal treatment wash coat before priming.
<br /> c. Touch up bare areas and shop-applied prime coats that have been damaged. Wire-brush, clean with
<br /> solvents recommended by paint manufacturer, and touch up with the same primer as the shop coat.
<br /> 5. Galvanized Surfaces: Clean galvanized surfaces with non-petroleum-based solvents so surface is free of oil
<br /> and surface contaminants. Remove pretreatment from galvanized sheet metal fabricated from coil stock by
<br /> mechanical methods.
<br /> D. Existing Wall Preparation for Renovation Projects: In addition to all preparation items in 3.2, the Contractor shall
<br /> include in his Base Bid repair and repointing of masonry block walls to meet the requirements for new masonry
<br /> block and gypsum walls prior to applying wall finishes.
<br /> E. Materials Preparation: Mix and prepare paint materials according to manufacturer's written instructions.
<br /> 1. Maintain containers used in mixing and applying paint in a clean condition, free of foreign materials and
<br /> residue.
<br /> 2. Stir material before application to produce a mixture of uniform density. Stir as required during application.
<br /> Do not stir surface film into material. If necessary, remove surface film and strain material before using.
<br /> F. Tinting: Tint each undercoat a lighter shade to simplify identification of each coat when multiple coats of the same
<br /> material are applied. Tint undercoats to match the color of the finish coat, but provide sufficient differences in shade
<br /> of undercoats to distinguish each separate coat.

<br /> A. General: Apply paint according to manufacturer's written instructions. Use applicators and techniques best suited
<br /> for substrate and type of material being applied.
<br /> 1. Do not paint over dirt, rust, scale, grease, moisture, scuffed surfaces, or conditions detrimental to formation
<br /> of a durable paint film.
<br /> 2. Provide finish coats that are compatible with primers used.
<br /> 3. The term "exposed surfaces" includes areas visible when permanent or built-in fixtures, convector covers,
<br /> covers for finned-tube radiation, grilles, and similar components are in place. Extend coatings in these areas,
<br /> as required,to maintain the system integrity and provide desired protection.
<br /> 4. Paint surfaces behind movable equipment and furniture the same as similar exposed surfaces. Before the
<br /> final installation of equipment, paint surfaces behind permanently fixed equipment or furniture with prime coat
<br /> only.
<br /> 5. Paint interior surfaces of ducts with a flat, nonspecular black paint where visible through registers or grilles.
<br /> 6. Paint back sides of access panels and removable or hinged covers to match exposed surfaces.
<br /> 7. Finish exterior doors on tops, bottoms, and side edges the same as exterior faces.
<br /> 8. Finish interior of wall and base cabinets and similar field-finished casework to match exterior.
<br /> 9. Sand lightly between each succeeding enamel or varnish coat.
<br /> B. Scheduling Painting: Apply first coat to surfaces that have been cleaned, pretreated, or otherwise prepared for
<br /> painting as soon as practicable after preparation and before subsequent surface deterioration.
<br /> 1. The number of coats and the film thickness required are the same regardless of application method. Do not
<br /> apply succeeding coats until the previous coat has cured as recommended by the manufacturer. If sanding is
<br /> required to produce a smooth, even surface according to manufacturer's written instructions, sand between
<br /> applications.
<br /> 2. Omit primer on metal surfaces that have been shop primed and touchup painted.
<br /> 3. If undercoats, stains, or other conditions show through final coat of paint, apply additional coats until paint
<br /> film is of uniform finish, color, and appearance. Give special attention to ensure edges, corners, crevices,
<br /> welds, and exposed fasteners receive a dry film thickness equivalent to that of flat surfaces.
<br /> 4. Allow sufficient time between successive coats to permit proper drying. Do not recoat surfaces until paint has
<br /> dried to where it feels firm, does not deform or feel sticky under moderate thumb pressure, and where
<br /> application of another coat of paint does not cause the undercoat to lift or lose adhesion.
<br /> C. Application Procedures: Apply paints and coatings by brush, roller, spray, or other applicators according to
<br /> manufacturer's written instructions.
<br /> 1. Brushes: Use brushes best suited for the type of material applied. Use brush of appropriate size for the
<br /> surface or item being painted.
