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.

I'm confused .. more than usual it seems that you need to
attach hook/loop to the plywood - not the cushion .. ?
... .unless the cushion's H&L is worn out or compromised ?
Can't she hand-stitch some small pieces of H&L to the cushions ?
.... staple some to the plywood ?

Sorry about that. Your confusion is understandable. The cushion's H&L has certainly seen better days. It's the
H portion on the cushions and not only have some of the stiches ripped out but there is "debris" in the hooks -
lint, etc.- which renders the hooks less effective.

Can't she hand-stitch some small pieces of H&L to the cushions ?

Probably, but there is a lot less friction between plywood and fabric than there is between 2 fabric surfaces. The
Dual Lock is much stronger than any H&L strips would be. I think the amount of H&L that would be needed would
require a lot of hand-stitching through the relative thick backing of the H&L strips and especially the plastic of the
Dual Lock. Doable, but it would be tough on the hands.

Maybe she should use some 40 grit adhesive backed sandpaper on the plywood. That would add some friction. ;-)

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

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

An upholsterer would have and can do what needs to be done at a cost.

I suggest you go to Hobby Lobby (Hob-nobby Lobby) or your local fabric store and get at least 2, maybe 3, ready made buttons with eyes on the back side.... like this
https://www.flickr.com/photos/438361...posted-public/
https://www.flickr.com/photos/438361...posted-public/

These buttons are about the size of a nickel. Quarter size buttons would do fine, also. Attach a string to the eye and run the string from inside the back of the cushion (along the zipper area). Attach the string to the plywood, pulling/securing the cushion to the back of the ply. Maybe get some extra buttons, in case a button or eye breaks, you'll have replacement buttons. This may be your lease expensive fix and easy to do. Hobby Lobby or fabric store may have a large needle for threading string through the fabric.

Sonny

Get 2 or 3 buttons per cushion.

A thin strip of wood, like a long ruler, could be tucked inside the cushion zipper area, holes drilled into the strip for running the string attachments.... no need to buy buttons.

I'm not quite sure I understand the process completely, but this sounds kind
of permanent, right? Permanent as in the cushions can't be easily removed
for vacuuming, etc.?

For what it's worth, the couch is sort of like this one, where the loose seat cushions
kind of get shoved under the permanently attached back cushions.

Info: The surface under the cushions is called the decking.

Many sofa cushions have semi-circle rings on the cushions' sides, at/near the back . These rings are attached to clips on the inside of the arms.... tucked down into the sides of the sofa between the arms and decking. These attachments hold the cushion in place. The ring is sewn in place via a strip of fabric. The clips are attached to elastic bands that are stapled to the sofa frame, tucked down inisde and below the arms and decking crevice. The clip allows for removing the cushion when needed.

The button or wood strip attachment can be similarly applied to the ply. The string can be looped and the ply aspect can have an "S" hook type of releasing attachment to hook onto the string loop, hence the cushion can be easily removed. This method is DIY, quick and easy, doesn't require sewing anything (except for running the button's/wood's string through the back of the cushion fabric. It's another form of the typical upholstery ring-clip attachment, but a DIYer alternative.

As per your pic, I have a similar sofa in the shop right now. I'll get some pics of the button and/or wood strip procedure and post..... hopefully this evening, depends on how fast/convenient I can do it.

The clip and loop explanation makes more sense to me than your previous suggestion. Pictures would be nice though. ;-)

Goop?

Often, a swivel type clasp is used for securing cushions to the sofa proper..... in your case the plywood.
https://www.walmart.com/ip/Swivel-Ba...of-6/308664373

There needs to be some attaching piece(s) on the cushion (corners) to clip to. No matter what kind of DIY fix, this concept of attachment is likely your best, easiest, least expensive, most permanent, cushion-removable fix.

Probably the springs have not weakened. Rarely do I see broken springs. Most likely the spring supports have failed in some capacity, not the springs themselves. I see and fix this fairly often with older furniture. Spring support failure cause: 1) clips loosen or detach from the wood frame 2) Spring ties (string/twine) loosen or break 3) jute webbing or other banding straps loosen or its attachments (nails, staples) fail 4) a broken or loosened board (frame member, wood joint). None of these repairs are difficult, but more time consuming.... upholstery, in general, is really simple and easy work. For these internal fixes, it's just a matter of diving into the internals to access the problem..... just awkward maneuvering often times. We did a ply-sheet fix for Mom's sofa seating (spring support failure), until I fixed it later.

I have done some upholstery repair in the past and as you say, it's not difficult. However,
"it's just a matter of diving into the internals to access the problem" is a tad simplistic.

"Diving in" is easy. It's the "climbing back out" that poses the problem for me :-)

I dove right in to open up this box spring to get it up the stairs. Once it was upstairs, closing
it back up was as simple as a bunch of staples, but the sloppy closure method will remain
hidden until the mattress is moved again. IOW, if the broken part is not accessible from an
area that will be hidden from view, I'm screwed. :-)

Mattress diving is not upholstery.

This is mattress diving.... in college we competed against one another in seeing how far we could mattress dive. We would wet the dorm hallway, place a mattress down, run and jump on the mattress to see how far we would travel. https://www.flickr.com/photos/438361...posted-public/

We also played golf in those halls, a club house (i.e., beer) at each end of the hall. Good times with college buddies!

Epoxy generally has some flexibility, but not much. For some
applications a product called Flex Coat (an epoxy used for fishing rod
wraps) might be an option. For your application I think something like
3M 77 spray on contact adhesive might work better. I have found that
when sprayed on a single surface and applied wet (right away) its a
decent temporary bond, and when sprayed on both surface and left to get
tacky before pressing together it makes a more permanent bond. It does
seem to remain flexible. More than epoxy anyway.

Other contact adhesives may also work, but I keep 3M 77 on hand and use
it all the time.

I keep thinking about the aftermath of a failed glue-job .. uughh.
As opposed to a failed sewing job - which would be easy to
remove / re-do and leave little evidence afterwards.
If the cushion covers are removeable - it could be machine-sewn ;
even if hand-stitched it should only take about 30 minutes per
cushion. Sew 1 or 2 6 inch diagonal strips - in from each corner -
on the cushoins ; staple 3 or 4 shorter strips to the plywood so
that they cross the cushion strips at a 90.

I've used E-6000 for plastic to cloth in the past, specifically for
covering a CD binder with faux fur. It's held up well, and I gather
E-6000 is widely used for fabric applications. It smells bad while
curing and will take a day or so to set.

I see it is now a whole family of products:

http://eclecticproducts.com/products/e6000/

I use a little at a time for various projects, and am on my third 2 oz
tube in about 20 years. Unlike some other adhesives I've used, it lasts
pretty well after opening.

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.


Silicone?
