I. All painting specifications for General Services Administration historic properties shall include the following clause in the Special Conditions Section:
��������� All paint will be custom tinted by computer matching. Color selection must follow the codes indicated on the finish schedule. Accurate color reproduction is accomplished by matching modern paints to the sample color chips corresponding to each code. There are two coding systems for describing color. They are the Munsell and Plochere color systems.
The contractor must obtain the coded color chips for each color indicated in the finish schedule. Chips are to be purchased directly from the following firm(s):
Munsell Color System www.munsell.com
Plochere Color System www.plochere.com
1. Chips each range around $10. Coded color chips must be computer matched. Major paint manufacturers known to be capable of computer color matching include Sherwin Williams, Benjamin Moore, and Duron. Visual matching is not acceptable.
2. Written verification of having had coded color chips computer matched to paints will be submitted to the Contracting Officer 48 hours prior to painting. These verifications must be written on paint manufacturer's stationery and hand signed by the individual conducting the computer color matching. No substitution for coded colors will be accepted."

Do not stir surface film into material. Remove film and,
if necessary, strain material before using.
A. Verification of Conditions:
1. Inspect the work for any serious defects or
conditions which would interfere or prevent a
satisfactory application of materials under this
2. Do not proceed with the work until corrections have
been made. Application shall be deemed acceptance
of the related surfaces.
3. No painting shall be performed until surfaces have
been properly prepared. Beginning work shall
constitute acceptance of base surfaces as found and
any subsequent failure or development of defects in
the painting work shall be corrected at no
additional expense to the Government.

any bright or plated work adjacent to painted areas
and not to spatter marble or other finished work.
3. Protect work of other trades, whether to be painted
or not, against damage by painting and finishing
work. Correct any damage by cleaning, repainting,
repairing or replacing, as acceptable to the
4. Provide "Wet Paint" signs as required to protect

restore all damaged or defaced painting work
B. Surface Preparation:
1. Perform preparation and cleaning procedures in accordance with paint manufacturer's instructions and as herein specified, for each particular substrate condition.
CAUTION: PAINT MAY CONTAIN LEAD, AND SURFACES SHOULD BE TESTED FOR LEAD CONTENT IN ADVANCE OF WORK. IF THE TEST IS POSITIVE AND YOU ARE NOT CERTIFIED TO HANDLE LEAD-ABATEMENT TASKS IT IS ILLEGAL FOR YOU TO PERFORM FURTHER WORK.

primed by others.
3. Remove hardware, hardware accessories, machined
surfaces, plates, lighting fixtures, and similar
items in place and not to be finish-painted, or
provide surface-applied protection prior to surface
preparation and painting operations. Remove, if
necessary, for complete painting of items and

4. Clean surfaces to be painted before applying paint
or surface treatments. Remove oil and grease prior
to mechanical cleaning. Prior to painting,
surfaces shall be clean, dry and free of foreign
materials which will adversely affect adhesion of
appearance of the applied coating.
5. Program cleaning and painting so that contaminants
from cleaning process will not fall onto wet,
3.03 ERECTION, INSTALLATION, APPLICATION
A. Stripping Scratched Painted Metal Interior Doors:
1. Apply stripping materials to entire surface in
accordance with manufacturer's recommendations and
to match the results obtained in the approved test
applications. Provide neutralizers, cleaning
agents and other related materials recommended by
the stripper manufacturer.
2. Perform stripping in a manner which results in
uniform stripping of all surfaces without streaking
or damage to substrate. Use tools that will not
gouge or disfigure the substrate.
3. On completion of stripping, clean all residue from
treated surfaces with damp sponge and neutralize
area as required. Surface shall be free of oil and
containments that may affect the adhesion of filler
4. If substrate exhibits superficial scratches, polish
out in an even plane with successively finer grades
of wet and dry sandpaper (#180-#400). Fill gouges
and deep scratches with epoxy filler prior to
sanding in accordance with manufacturer's
5. Upon completion of filling and sanding, wipe
surfaces with a tack cloth.
B. Repainting Metal Doors:
1. General: Apply paint in accordance with
manufacturer's directions. Use applicators and
techniques best suited for substrate and type of
material being applied.
a. Paint colors, surface treatments, and
finishes, to be approved by RHPO.
b. Provide finish coats which are compatible with
prime paints used.
c. Apply additional coats when undercoats, stains
or other conditions show through final coat of
paint, until paint film is of uniform finish,
color and appearance. Give special attention
to ensure that surfaces, including edges,
corners, crevices, welds, and exposed
fasteners receive a dry film thickness
equivalent to that of flat surfaces.
2. Scheduling Painting: Apply first-coat material to
surfaces that have been cleaned, pretreated or
otherwise prepared for painting as soon as
practicable after preparation and before subsequent
a. Allow sufficient time between successive
coatings to permit proper drying.
b. Do not recoat until paint has dried to a firm,
undeformed, unsticky surface under moderate
thumb pressure, and application of another
coat of paint does not cause lifting or loss
of adhesion of the undercoat.
3. Minimum Coating Thickness: Apply materials at not
less than manufacturer's recommended spreading
rate, to establish a total dry film thickness as
indicated or, if not indicated, as recommended by
4. Prime Coats:
a. Apply prime coat on material which is required
to be painted or finished, and which has not
already been prime coated.
b. Recoat primed and sealed surfaces where there
is evidence of suction spots or unsealed areas
in first coat, to assure a finish coat with no
burn-through or other defects due to
5. Pigmented (Opaque) Finishes: Completely cover to
provide an opaque, smooth surface of uniform
finish, color, appearance and coverage.
Cloudiness, spotting, holidays, laps, brush marks,
runs, sags, ropiness or other surface imperfections
will not be acceptable.
6. Completed Work: Match approved samples for color,
texture and coverage. Remove, refinish or repaint
work not in compliance with specified requirements.
1. During progress of work, remove from site discarded
paint materials, rubbish, cans and rags at end of
each work day.
2. Upon completion of painting work, clean window
glass and other paint-spattered surfaces. Remove
spattered paint by proper methods of washing and
scraping, using care not to scratch or otherwise
damage finished surfaces.
