Using one of the brushes (Item 8, Table 3-3) or the plastic applicator (Item 11, Table 3-3), apply one even
coat of adhesive to the roughened surface of the tank and the prepared patch. The coat of adhesive should
be approximately 10 mil. (0.025 cm) thick.
15.
Let adhesive set until tacky (approximately 5 to 10 minutes). Test by lightly touching one knuckle into
adhesive. Lift slowly. When knuckle lifts fabric briefly, and no adhesive is left on knuckle, it is tacky.
16.
Once adhesive is tacky, bring ends of patch together (adhesive side out), and position center of patch onto
center of hole (Fig. 3-3).
FIGURE 3-3. APPLYING PATCH
17.
Smooth down patch with edge of hand, one end at a time, so as to avoid any air bubbles.
18.
Use a roller, or equivalent, to firmly roll down the entire patch, from center of patch out toward edges to
prevent formation of air bubbles.
19.
If a second patch is being applied, proceed with step 20, below; otherwise proceed to step 22.
NOTE
Maximum shelf life of mixed adhesive is given in Table 3-4. If second patch is to be
applied, ensure that it is done within this time limit. Repair will not succeed if
mixed adhesive sits too long.
