UNIT MAINTENANCE

Pack adhesive in core cells to fill exposed area above surface of panel skin.

Cure adhesive at room temperature (75 degrees F) for 72 hours. If a heat source is available, alternate

cures can be achieved by exposing the repaired area to 150 degrees F for 3 to 4 hours, or 200 degrees F

for 40 to 60 minutes. If 150 degree F or 200 degree F cures are used, allow additional time for repaired

area to warm to curing temperature. Ensure that the surface temperature of the CBC does not exceed

225 degrees F.

Sand cured adhesive with sandpaper to obtain a smooth contour with surface of panel skin.

Wipe sanded area and patch (1) with a clean cloth dampened in solvent and immediately wipe solvent

from surfaces with a clean, dry cloth.

Mix an amount of adhesive in accordance with manufacturer's instructions, sufficient to coat one side of

patch.

Apply a thick film of adhesive to mating surface of patch (1).

Place patch over prepared area in same orientation used in earlier step.

Align holes (2) and using hand blind riveter, install 1/8 inch (3.18 mm) diameter blind rivet (6).

Clean repaired surface.

Caulk around repair patch (1). (Refer to WP 0025).

Apply alodine solution. Apply the alodine solution with a brush, paint spray gun, cellulose sponge, etc.,

to the cleaned and rinsed aluminum surface, liberally, quickly and evenly. Allow it to act from 1 to 5

minutes before rinsing.

NOTE

The solution should be applied to only as much surface as can be coated

and rinsed before the alodine solution dries.

Proceed with the coating and rinsing until the entire surface is coated with alodine.

Rinse. Before the alodine solution dries, wipe it from the surface with a clean cloth or sponge wet with

clean water. The alodine solution may also be rinsed from the surface with clean water from a hose.

Dry. After the rinsing has been finished, allow the work to air dry. Drying can be speeded by wiping with

clean, dry rags. Clean, dry, compressed air should be used to blow moisture from joints, depressions,

etc., and to speed the drying. When the surface is entirely dry, the part is ready for service without further

treatment, or if desired, it may be painted in accordance with manufacturer's directions.

Refinish in accordance with WP 0039.
