Good glue for foamcore

[Ron Marshall]

I want to glue some of my foamcore sheets back to back. What is a good glue for this? I won't need to reposition or remove it.

I use a double sided tape gun.Try Light Impressions

How big?

If not too big, how about rubber cement? Coat both sides, let them almost dry, then put them together. Should be permanent.

I use 3M 3/4" double sided mounting tape. A good trick is to mount so that curve sides are opposite face to face that way they pull each other flat.

Gorilla Glue?

3M super 77 spray. does not attack the foam, will be there forever. repositional for a short period of time. easy to find and use. once pressed together firmy, aint gone nowheres forever. I also use this for bellows. good stuffs.

Contact cement does the job but the foam needs to be aerated for a day or so to lose the vapors.

I once met a man who built finely detailed full size mock-ups of helicopter cockpits out of foamcore for Boeing. He was an artist. He used hot melt glue almost exclusively. When I tried it, it was a mess. but I was impatient.

you might also try polyvinyl acetate ( pva ) sold in
all sorts of art supply stores. its made for gluing paper.

I built several pinhole cameras out of foam board and Gorilla Glue. The foam board gave up before the glue joints did. Good luck!

I build 6x6 lensboards for Deardorff (that also fit my Plaufel Profia) from foam board. It's a super fast and super cheap way how to get a new lens to work if you don't own one of those expensive mounting iris devices. The office max glue stick works as well as a Weldbond glue for me but is less messy. I tried Pliobond once and it dissolves the foam.

If you are concerned about acid free, Best-Test makes a white rubber cement that works well on foamcore. I have used it for making foamcore shipping containers for my prints. Good ventilation is suggested!
