Acetone and repair adhesives are
flammable and toxic. Keep away
from heat, sparks and open flame.
Wear safety glasses, gloves and
protective clothing to prevent
contact. Wear a NIOSH approved
air-purifying respirator for organic
ventilated area. If contact occurs,
flush areas with water and get
medical attention. If ingestion
occurs get medical attention at
The adhesive should be used
sparingly. Two (2) thin, even
coats will provide better adhesion
than two thick, puddled coats.
Acetone is used as a solvent for

surrounding area on the damaged surface of the cell
with a piece of dean cheesecloth (item 16, table 2-11)
dampened with acetone (item 3, table 2-11) to remove
any foreign material. The surface must be absolutely
dean and dry in order to apply the patch.
(b) Cut a patch from the fabric (item 19,
table 2-11 for interior repair, item 25, table 2-11 for
exterior repair) for the repair area The patch should be 3
inches larger in all directions than the damaged area.
Hand buff this material lightly and thoroughly on the
gum side with emery cloth (120 grit) (item 17, table 2-
11). Remove buffing dust by wiping patch with
cheesecloth (item 16, table 2-11 ) dampened with
acetone (item 3, table 2-11).
(c) Hand buff damaged area of cell
lightly and thoroughly with emery cloth (120 grit) (item
17, table 2-11). Area to be buffed should be slightly
larger (1/8 to 1/4 inch) in size than the patch. Remove
buffing dust with a piece of dean cheesecloth (item 16,
table 2-11) slightly dampened with acetone (item 3,
Repair adhesive is flammable and
should be kept away from any
Adhesive materials should be kept
containers in a cool, dry place.
(d) Refer to paragraph c(1)(e) for
Do not apply adhesive beyond
(e) Apply one coat of adhesive (item
18, table 2-11) to buffed side of patch and buffed area
of cell, allow to dry 20-60 minutes.
To determine if adhesive is tacky,
test it by pressing a knuckle
surface and withdrawing it (it
practical). Proper tackiness is
achieved when a few threads of
adhesive stick to the knuckle.
This procedure is referred to as
the knuckle test NOTE If adhesive
adhesive may be done only once
(total of three coats). If dry time is
again exceeded, remove adhesive
from applied area using, acetone
and/or buffing with emery cloth
(120 grit minimum).
(f) Apply a second coat of adhesive
(item 18, table 2-11) to buffed areas of patch and cell,
allow to dry until tacky. Adhesive can become tacky
temperature and humidity. Perform knuckle test.
(g) If necessary to restore the tack of
the cemented surfaces, use a dean piece of cheesecloth
(item 16, table 2-11) dampened with acetone (item 3,
table 2-11 ) and lightly wipe over cemented areas.
Allow solvent to evaporate 10-20 seconds or until
cemented areas become "tacky."
