Overall question:

Will epoxy hold flexible plastic to fabric? Specifically, West Systems G-Flex
epoxy and 3M Dual Lock adhesive tape.

I'm trying to help a friend extend the life of a couch. To keep the cushions
from sliding forward, the manufacturer used Velcro-like hook & loop material
between the bottom of the cushions and the fabric that covers the springs in
the base of the couch. The H&L strips are sewn onto the cushions and base and
have served their purpose well for many years.

Unfortunately, the springs have weakened, so my friend put a piece of 3/4"
plywood under the cushions to add firmness. This works fine, except that the
cushions slide forward whenever someone sits on the couch since the H&L is no
longer connected.

She tried some of the 3M Dual Lock adhesive tape between the cushions and
plywood, but the tape does not stick to the fabric on the cushions for very
long. After a few "sitting sessions" the tape, which is actually a hard but
flexible plastic, loses it's adhesion to the fabric bottom of the cushion.

Short of taking the cushions to an upholsterer to see if they can sew the Dual
Lock to the cushions, I'm wondering if the West Systems G-Flex epoxy might
hold the tape to the fabric.

Other suggestions for preventing the cushions from sliding on the plywood
would certainly be appreciated.

Try adding thick Super glue to the adhesive on the tape to penetrate the fabric.
