REPAIR OF SHELTER PANEL DELAMINATION
0033 00
WARNING
To avoid injury to personnel, safety glasses must be worn
during drilling and sanding operations.
CAUTION
Make sure the drill bit has a drill stop attached to prevent
the drill bit from exceeding a depth of 5/8 inch.
2. Using a drill with a #11 bit, drill clearance holes (number of holes is dependent on the size of the
delamination) for 3/16 inch pop-rivets spaced (not greater than five inches on center) within the
chalk line.
3. Using the outline of the marked delaminated area, make the surrounding area approximately two
feet wide with polyethylene.
WARNING
To avoid injury to personnel, gloves must be worn when
working with adhesive.
4. In a clean unwaxed container, mix Epic R1002 adhesive with Versamid 140 material as follows:
By Weight: 15 oz. Epic to 5 oz. Versamid
By Volume: 2 parts Epic to 1 part Versamid
NOTE
The mixed adhesive must be used within the time specified
below, considering the ambient temperature.
60F 2 hours
70F 1 hour
80F 40 minutes
90F 20 minutes
CAUTION
Inject adhesive slowly. Too much force could increase the
size of the delamination and cause additional damage.
5.
Using a caulking gun, inject adhesive into the bottom hole until adhesive begins to seep out of
the holes in line with the injection hole.
6.
Using a pop-rivet gun, (dip rivet in polysulfide sealer for exterior delaminations), install one 3/16
inch rivet in the hole.
7.
When the holes on each side of the injection hole are riveted, install a rivet in the injection hole
and use the next series of pre-drilled holes to continue injecting adhesive.
8.
Repeat steps 5 through 7 until all holes are filled with adhesive and pop-rivets.
9.
Clean the excess adhesive with non-residual cleaning solvent (Isopropyl alcohol).
