A. General: Install acoustical panel ceilings to comply with manufacturer's written instructions."
B. Suspend ceiling hangers from building's structural members and as follows:
1. Install hangers plumb and free from contact with insulation or other objects within ceiling
plenum that are not part of supporting structure or of ceiling suspension system.
2. Splay hangers only where required to miss obstructions; offset resulting horizontal forces
by bracing, countersplaying, or other equally effective means.
3. Where width of ducts and other construction within ceiling plenum produces hanger
spacings that interfere with location of hangers at spacings required to support standard
suspension system members, install supplemental suspension members and hangers in
form of trapezes or equivalent devices. Size supplemental suspension members and
hangers to support ceiling loads within performance limits established by referenced
standards and publications.
^^ 4. Secure wire hangers to ceiling suspension members and to supports above with a
minimum of three tight turns. Connect hangers directly either to structures or to inserts,
eye screws, or other devices that are secure and appropriate for substrate and that will
not deteriorate or otherwise fail due to age, corrosion, or elevated temperatures.
5. Do not attach hangers to steel roof deck. Attach hangers to structural members.
6. Space hangers not more than 48 inches (1200 rnm) o.c. along each member supported
directly from hangers, unless otherwise indicated; provide hangers not more than 8
inches (2,00 Ann,,) from ends of each member.
C. Install edge moldings and trim of type indicated at perimeter of acoustical ceiling area and
where necessary to conceal edges of acoustical panels.
1. Screw attach moldings to substrate at intervals not more than 15 inches (400 mm) o.c.
and not more than 3 inches ("75 inim) from ends, leveling with ceiling suspension system
to a tolerance of 1 f8 inch in 12 fret (3,2 nnrn in 3.66 .m. ). Miter corners accurately and
connect securely.
2. Do not use exposed fasteners, including pop rivets, on moldings and trim.
D. Install suspension system runners so they are square and securely interlocked with one
another. Remove and replace dented, bent, or kinked members.
E. Install acoustical panels with undamaged edges and fit accurately into suspension system
runners and edge moldings. Scribe and cut panels at borders and penetrations to provide a
neat, precise fit.
1. Arrange directionally patterned acoustical panels as follows:
a. Install panels with pattern running in one direction parallel to long axis of space.

2. For square -edged panels, install panels with edges fully hidden from view by flanges of
suspension system runners and moldings.
3.4 CLEANING
A. Clean exposed surfaces of acoustical panel ceilings, including trim, edge moldings, and
suspension system members. Comply with manufacturer's written instructions for cleaning and
touchup of minor finish damage. Remove and replace ceiling components that cannot be
successfully cleaned and repaired to permanently eliminate evidence of damage.

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 Architect about anticipated problems when using the materials specified over

3.2 PREPARATION
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.
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.
x,
1. Schedule cleaning and painting so dust and other contaminants from the cleaning
.. process will not fall on wet, newly painted surfaces.
C. Surface Preparation: Clean and prepare surfaces to be painted according to manufacturers
written instructions for each particular substrate condition and, as specified.
1. Provide barrier coats over incompatible primers or remove and reprime.
2. 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.
D. Material Preparation: Mix and prepare paint materials according to manufacturer's written
instructions.
E. Tinting: Tint each undercoat a lighter shade to simplify identification of each coat when multiple
coats of same material are applied. Tint undercoats to match the color of the finish coat, but
provide sufficient differences in shade of undercoats to distinguish each separate coat.
3.3 APPLICATION
A. General: Apply paint according` to manufacturers written instructions. Use applicators and
�-• techniques best suited for substrate and type of material being applied.
1. Paint colors, surface treatments, and finishes are indicated in the paint schedules.
2. Do not paint over dirt, rust, scale, grease, moisture, scuffed surfaces, or conditions
" detrimental to formation of a durable paint film.
3. Provide finish coats that are ,compatible with primers used.
4. The term "exposed surfaces" includes areas visible when permanent or built-in fixtures,
grilles, convector covers, covers for finned -tube radiation, and similar components are in
place. Extend coatings in these areas, as required, to maintain system integrity and
provide desired protection.
PAINTING 09912-5
0699-3
5. Paint surfaces behind movable equipment and furniture the same as similar exposed
surfaces. Before final installation of equipment, paint surfaces behind permanently fixed
equipment or furniture with prime coat only.
6. Paint interior surfaces of ducts with a flat, nonspecular black paint where visible through
registers or grilles.
7. Paint backsides of access panels and removable or hinged covers to match exposed
surfaces.
8. Finish exterior doors on tops, bottoms, and side edges the same as exterior faces.
9. Finish interior of wall and base cabinets and similar field -finished casework to match
exterior.
10. Sand lightly between each succeeding enamel or varnish coat.
B. Scheduling Painting: Apply first coat to surfaces that have been cleaned, pretreated, or
otherwise prepared for painting as soon as practicable after preparation and before subsequent
surface deterioration.
1. The number of coats and film thickness required are the same regardless of application
method. Do not apply succeeding coats until previous coat has cured as recommended
by manufacturer. If sanding is required to produce a smooth, even surface according to
manufacturer's written instructions, sand between applications.
2. Omit primer over metal surfaces that have been shop primed and touchup painted.
3. If undercoats, stains, or other conditions show through final coat of paint, apply additional
coats until paint film is of uniform finish, color, and appearance. Give special attention to
ensure that edges, corners, crevices, welds, and exposed fasteners receive a dry film
thickness equivalent to that of flat surfaces.
4. Allow sufficient time between successive coats to permit proper drying. Do not recoat
surfaces until paint has dried to where it feels firm, and does not deform or feel sticky
under moderate thumb pressure, and until application of another coat of paint does not
cause undercoat to lift or lose adhesion.
C. Application Procedures: Apply paints and coatings by brush, roller, spray, or other applicators
