3. APPLYING ADHESIVE
A. For the purposes of repair the words ‘tacky’ and aggressive tack are defined as follows:
(1). When the word ‘tacky’ is used, it means that if the fingers are lightly dragged across
the adhesive, it tends to pull off the base fabric or the previous coat.
(2). When the words ‘aggressive tack’ are used, they mean that when applying light
pressure to the adhesive, it has bonded to the previous coats and tends to retain, or
stick to, the fingers.
B. Apply three (3) coats of adhesive to each mating surface, allowing the previous coats to dry
completely before applying additional coats.
C. When the third coat develops an aggressive tack, apply the patch or make the seam.
D. If the third coat has dried it may be enlivened with a cloth dampened with MEK solvent.
Apply just enough solvent to recreate an aggressive tack on the surface. Reactivation may
be carried out up to three (3) hours after the application of the last coat of solution.
Note: If the solution becomes too dry between coats, or if any air bubbles are
not completely rolled out, or if the mating surfaces are dry, a ‘dry joint’
will result. The joint will appear sound, but it can be quite easily pulled
apart. When testing with a finger, the solution must show aggressive
tack, but no pick-up of solution. Rolling must be firm, working from the
centre of the area toward the edges, expelling the air.
E. Careful attention is to be given when rolling down seams and patches, particularly on
curved edges. Puckers and channels must be avoided, and all seams MUST be rolled twice.
Caution: Solvents must not be used for removing surplus adhesive from repair
areas.
