Section IV. REPAIR OF DRUM
5-14. Applying Elastomer
a. Preparing Surface
(1) Lightly scuff the surface with a rotary wire brush
or suitable roughing tool.
Be careful not to damage cord layer.
b. Degrease Surface
(1) Apply a small amount of denatured ethanol to
degrease the surface.
(2) Apply a coat of surface conditioner onto the prepared
surface with a brush. Apply as thin as possible. Let dry for
Skin contact should be avoided by the use of
suitable protective equipment as harmful or
irritant effect may result.
c. Combining the Reactive Components
(1) Mix the Elastomer with the following mixing ratio:
3 parts Base to 1 part Solidifier by volume.
2.3 parts Base to 1 part Solidfier by weight.
Complete mixing is the most important step in
the use of Elastomer
(2) After using part of the Base
component, the lid should be REPLACED
(3) Apply the Elastomer directly

a. Exterior Patch (Fuel Drums).
(1) Clean damaged area of all contaminants and foreign
matter. Wash drum exterior with an approved detergent
(2) Refer to figure 5-10 and buff damaged area; buff
the drum wall 5 inches (13cm) in each direction from tear.
Remove dust and rewash with detergent solution.
(3) Refer to figure 5-11 for typical patch pattern and
prepare patch assembly as follows:
(a) Cut first patch from 42153 stock. Cut patch large
enough to extend 3 inches (7.62cm) in all directions beyond
(b) Cut second patch from 42153 stock. Cut patch 1/2
inch (1.3cm) larger than first patch.
(c) Cut a third patch from 42113 stock. Cut patch 1/2
inch (1.3 cm) larger than second patch.
Under normal atmospheric conditions the cement
will dry in 2 to 3 minutes. Excessive humidity
will require longer drying time. Limit use of ap-
plicator brush to 3918 cement. Do not use an
applicator brush in more than one type of
