Products listed in succeeding Part 2 articles have been researched and evaluated and are believed to be comparable to products of other manufacturers listed. However, due to differences among manufacturers' individual product formulas, some products may have advantages or disadvantages when compared to similar products of other manufacturers. Base selection of product on coating-performance characteristics required.

PART 3 - EXECUTION

3.1 EXAMINATION

A. Examine substrates, areas, and conditions under which the painting will be performed, with Applicator present, for compliance with requirements for paint application. Comply with procedures specified in PDCA P4-94.

1. Do not proceed with paint application until unsatisfactory conditions have been corrected and surfaces receiving paint are thoroughly dry.

2. Start of painting will be construed as Applicator's acceptance of surfaces and conditions within a particular area.

Coordinate primers specified in other Sections with undercoats and finish materials specified in this Section to ensure compatibility of materials. Some finish-coat materials, such as lacquers and epoxies, lift oil and oleoresinous air-dry primers. A long-oil finish coat may crawl and have poor adhesion when used over zinc-dust phenolic or baked primers.

B. Coordination of Work: Review other Sections in which primers are provided to ensure compatibility of the total system for various substrates. On request, furnish information on characteristics of finish materials to ensure use of compatible primers.

1. Notify Contracting Officer about anticipated problems when using the materials specified over substrates primed by others.

3.2 PREPARATION

Revise first paragraph and subparagraph below if additional requirements are necessary to suit Project.

A. General: Remove hardware and hardware accessories, plates, machined surfaces, lighting fixtures, and similar items already installed that are not to be painted. If removal is impractical or impossible because of size or weight of the item, provide surface-applied protection before surface preparation and painting.

1. After completing painting operations in each space or area, reinstall items removed using workers skilled in the trades involved.

B. Cleaning: Before applying paint or other surface treatments, clean substrates of substances that could impair bond of the various coatings. Remove oil and grease before cleaning.

1. Schedule cleaning and painting so dust and other contaminants from the cleaning process will not fall on wet, newly painted surfaces.

Always retain first paragraph and subparagraphs below for surface preparation. Proper surface preparation is essential for satisfactory coating performance. If necessary, revise requirements to include special procedures requested by manufacturers or to suit Project.

C. Surface Preparation: Clean and prepare surfaces to be painted according to manufacturer's written instructions for each particular substrate condition and as specified.

Coordination of shop-applied primers with finish coats is critical. See "Coordination of Work" Paragraph in "Examination" Article. If compatibility problems develop, it may be necessary to provide barrier coats over shop-applied primers or to remove the primer and reprime the substrate.

1. Provide barrier coats over incompatible primers.

Delete subparagraph and associated subparagraphs below if cementitious surfaces are not to be painted, or revise to suit Project.

2. Cementitious Materials: Prepare concrete unit masonry surfaces to be painted. Remove efflorescence, loose mortar, chalk, dust, dirt, grease, oils, mold and mildew.

a. Concrete block and mortar must be cured at least 30 days at 75° F before applying primer.

b. All bug holes, air pockets, chips and other voids are to be filled with patching compound.

c. For new surfaces, use abrasive blast-cleaning methods if recommended by paint manufacturer.

d. Determine alkalinity and moisture content of surfaces by performing appropriate tests. If surfaces are sufficiently alkaline to cause the finish paint to blister and burn, correct this condition before application. Do not paint surfaces if moisture content exceeds that permitted in manufacturer's written instructions.

Delete subparagraph below if not required.

Delete subparagraph and associated subparagraphs below if wood surfaces are not to be painted, or revise to suit Project.

3. Wood: Clean surfaces of dirt, oil, and other foreign substances with scrapers, mineral spirits, and sandpaper, as required. Sand surfaces exposed to view smooth and dust off.

a. Scrape and clean small, dry, seasoned knots, and apply a thin coat of white shellac or other recommended knot sealer before applying primer. After priming, fill holes and imperfections in finish surfaces with putty or plastic wood filler. Sand smooth when dried.

Delete four subparagraphs below if specified in other Sections.

Revise first subparagraph and associated subparagraphs below to suit Project.

4. Ferrous Metals: Clean ungalvanized ferrous-metal surfaces that have not been shop coated; remove oil, grease, dirt, loose mill scale, and other foreign substances. Use solvent or mechanical cleaning methods that comply with SSPC's (Steel Structures Painting Council’s) recommendations.

Delete subparagraph below if blast cleaning is not required. SSPC-SP 10/NACE No. 2 requires a higher level of preparation than is often justified. Reduce preparation level to SSPC-SP 6/NACE No. 3 if warranted.

a. Structural Steel and Miscellaneous Steel

1) Blast steel surfaces clean as recommended by paint system manufacturer and according to SSPC-SP 6/NACE No. 3 1994.

2) Treat bare and sandblasted or pickled clean metal with a metal treatment wash coat before priming.

3) Touch up bare areas and shop-applied prime coats that have been damaged. Wire brush, clean with solvents recommended by paint manufacturer, and touch up with same primer as the shop coat.

Delete first subparagraph below if touchup painting of shop-applied primers will be done by material erector or Installer.

5. Galvanized Surfaces: Clean galvanized surfaces with nonpetroleum-based solvents so surface is free of oil and surface contaminants. Remove pretreatment from galvanized sheet metal fabricated from coil stock by mechanical methods.

D. Material Preparation: Mix and prepare paint materials according to manufacturer's written instructions.

1. Maintain containers used in mixing and applying paint in a clean condition, free of foreign materials and residue.

2. Stir material before application to produce a mixture of uniform density. Stir as required during application. Do not stir surface film into material. If necessary, remove surface film and strain material before using.

3. Use only thinners approved by paint manufacturer and only within recommended limits.

If tinting is not required, delete below. Different tints will show through as topcoat erodes.

3.3 APPLICATION

H. Cut‑in edges of paint adjoining other materials or colors, clean and sharp with no overlapping.

I. Backprime interior woodwork, which is to receive paint or enamel finish, with enamel undercoater paint.

J. Before painting, remove switch, and coverplates, accessories, and minor hardware, lighting fixtures, and similar minor items or provide ample protection of such items. Upon completion of such space, reinstall removed items.

K. Remove covers and access panels for electrical systems from location and paint separately.

L. Finish prime painted equipment to color selected.

M. All nameplates and data plates that indicate manufacturer, model, size, capacity, codes, or identifying data printed on equipment, shall not be painted; carefully cut‑in.
