Repair. (figure 4-10)
Paint strippers can contaminate panel core, adhesive and sealer. Do not use paint
strippers to remove paint.
RFI/EMI shielded shelters should not be operated until a permanent patch has been
applied.
NOTE
The following procedures shall be used to repair small punctures that do not exceed
1/2-inch depth into foam core. All punctures must be patched immediately to prevent
water intrusion and/or radiation leakage (shielded shelters). Dents without punctures do
not require patching. However, if bare metal is exposed, touch up with paint (para 4-6).
Wall, ceiling and floor sandwich panels are alike in composition and construction. Repair
procedures are the same for all sandwich panels.
(1) Bend edges of puncture in below surface of unbroken face sheet. Do not allow broken edges to contact
opposite face.
(2) Remove loose fragments of foam and dust, using a vacuum, if necessary.
