How do I bind closed cell foam? on 01/13/2009 10:45:33 MST Print View

I want to used closed cell foam to make protective pouches for my photography equipment while backpacking. I've researched the available wraps, cases, and pouches and they seem heavy for what they do and are overpriced for how simple they are.

I want to create my own pouches from a cut cut closed cell foam pad purchased from REI. I'm just not sure how to bind and seal the seams of the pouches. Can you sew closed cell foam? Would glue work? What type of glue would be best? The foam I want to work with is between 1/4 and 3/8 inch thick.

Binding closed cell foam on 01/13/2009 10:55:54 MST Print View

I've had some success using contact cement (from the hardware store) to bind/join the edges of closed cell foam...but I've only done so on the "finished" edges of the foam pad. For the protective sleeves I've made, the clean cut of the outside edges of a new pad can be joined in a very durable seam following the contact cement directions (paint it on with the supplied brush, allow to dry for the specified time and then join).

FWIW, I've also used duct tape or clear plastic (mailing) tape to join edge seams, though that's not especially attractive.

I don't really care how they look, just that they work. The whole collection of gear will be kept inside a drybag stuff sack. I had thought of tape, but wasn't sure if the tape glue would leak. I'll have to give it a try.

Barge Cement is probably the best way to go. Here is a link to make a pot cozy out of closed cell foam

ditto Tad's suggesting of Barge cement. Our local hardware chain carries it (part of the Ace hardware "chain"). I've used it successfully on blue foam and a ridgerest pad.

If the methods shown in the Barge Cement Cozy instructions do not seem sturdy enough for you then augment the glued joints by barge cementing a narrow strip of light wt nylon cloth over the joint.

edit: I have a 12x20 z-folding bluefoam sit pad that used duct tape to hold the sections together ... used 4 seasons (MN) ... still holding well after several years

Duct tape on 01/13/2009 12:11:26 MST Print View

I made a pot cozy from an old ridgerest and duct tape, and the thing has held up for well over 1000 miles of backpacking the last few years, with few signs of wear. It definitely looks homemade, but it's worked fine.

Hi Kari

> I'm just not sure how to bind and seal the seams of the pouches.
I made my own camera pouch too. WP/B fabric outer, then a layer of 5 mm CCF, then a spinnaker liner just sewn to the outer at the top.

> Can you sew closed cell foam?
Yes - best done with the Lycra-clad neoprene, but possible.

> Would glue work? What type of glue would be best?
Yes. Contact, Gorilla, PU sealant...

Yup, Barge Cement

Made some foam double boot liners from that with tricot
glued to the inside and pu ripstop glued to the outside.

Nice idea! Did you bond the fabric to the foam before or after assembly?

3M FoamFast 74 Spray Adhesive is exactly what you are looking for If you want something stronger go for the 77 spray adhesive or headliner adhesive.

Perhaps duct tape? Just a redneck's 2 cents!
I used duct tape with closed cell foam and aluminum foil to make a pot cozy once, weighed about 2 oz.

I've had many years of use on a cup coozy made with the packing tape and lighter than duct tape. If you use the clear type it kind of destroys the red neck looks though.

I find PU the easiest to work with when gluing thin closed cell foam or neoprene.

Common brand names in the US are Shoe Goo, AquaSeal, Marine Goop, and many other brand names. Look for Goo or Goop in the name and it is probably the same kind of PU.

Gorilla Tape - with reservations on 12/13/2013 13:21:43 MST Print View

I used Gorilla Tape to make a custom fit camera case and lens case from a Walmart blue foam pad. It held up fine, but in hot weather small amounts of tape goo would stick to my lenses and camera -- just the outer plastic, I kept tape away from the lens elements. I sold the camera eventually, and it came off easily enough with isopropyl.
