Avoid any air bubbles. 19.   Use a roller, or equivalent, to firmly roll down the entire patch, from center of patch out toward the   edges to prevent formation of air bubbles. 20.   If a second patch is being applied, proceed with step 21, below; otherwise proceed to step 23. NOTE Maximum shelf life of mixed adhesive is listed in Table 2. If a second patch is to be applied,   ensure that it is done within the time limit. Repair will not succeed if the mixed adhesive sits   too long. 21.   Let first patch set for a few (approximately 2 to 3) minutes. 22.   Repeat steps 15 through 19, above, to apply second (outside) patch. Outside patch must be aligned with inside patch (outline of inside patch will be visible). 23.   Allow repair to set until cured before flexing fabric or putting tank back into service. Approximate curing times are listed in Table 3. NOTE       Times are for a thickness of approximately 0.10 inches (0.25 cm). Times will be       reduced for thicker sections and extended for thinner sections. Table 3. Curing Time for Fabric Repairs.
