3.01 ERECTION, INSTALLATION, APPLICATION
A. Make repairs to wood as required. See 06400-16-R, 06440-
01-R and 06440-04-R for guidance in repairing small
holes, dents and minor imperfections.
B. Resecure and repair any loose or damaged wood pieces.
See 06400-04-R, 06440-02-R and 06440-03-R for guidance.
C. Replace any missing or deteriorated wood features. See
06400-15-R for guidance.
D. Thoroughly clean the surface to be gilded. For guidance
on general dusting and maintenance, see 06400-01-P,
06200-01-P and 06400-01-R. For guidance on stripping
paint, see 06400-07-R and 06400-09-R. See also 06400-10-
R for additional wood refinishing guidance.
E. Apply gesso mixture over wood surface to be gilded to
smooth out the wood and fill small holes. Apply in many
thin layers. Several coats may be necessary in order to
sufficiently smooth the surface.
F. Apply mixture of gelatin and gilder's clay or "bole" over
gesso, or apply japan paint over the gesso.
G. Make stencils from cardboard to match original lettering
as closely as possible.
H. Lift gold leaf sheet from booklet using a gilder's tip.
I. Use the stencils as a guide and cut gold leaf to match
size, type and style of original lettering using a
gilder's cushion and gilder's knife.
J. Apply size to area to be gilded.
1. For matte finish: Cover the paint or "bole" with
shellac; apply a coat of varnish called "gold size"
to the wood surface. (This is a slow-drying size)
3. For burnished finish: Wet "bole" with a solution of
1 part alcohol to 4 parts water. (This is a quick-
K. Allow the surface to become tacky.
1. For matte finish: Approximately 10-12 hours.
2. For burnished finish: Approximately 1-3 hours.
L. When the surface has become tacky, position the gold leaf
and quickly place it over the surface using a gilder's
CAUTION: If leaf is applied while size is too wet, gold
will be 'drowned' and burnish will be killed. If size is
too dry, leaf will not adhere.
M. Smooth out sheets using a soft brush or clean cotton wad;
save any excess for patching later if necessary.
N. Before burnishing (if burnishing), wait 1-3 hours after
placing the gold leaf. The gesso and "bole" coating
needs to reach sufficient hardness before burnishing.
1. Burnish carefully using an agate burnisher. Using
gentle circular motions, rub the gold leaf using
slight pressure, gradually increasing pressure to
make firm strokes in one direction. Rub
sufficiently to achieve a dark mirror finish.
NOTE: TIMING IS CRITICAL TO SUCCESSFUL BURNISHING.
THEREFORE, THIS WORK SHOULD BE DONE BY A
PROFESSIONAL. If burnishing is performed too soon,
the gold leaf may mush; if burnishing is performed
too late, the gold leaf may chip.
O. If patching is required, cover surface with diluted
sizing and add a new leaf as above or use excess leaf
from previous applications.
