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

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

One more thought. Will the hook side of the velcro stick to the fabric?
You may only need one side of the Velcro.
