View Full Version : Adhesive for Styrofoam?

What is the proper adhesive to be used when glueing both the beaded and non-beaded (extruded) styrofoam together. Any and all suggestions welcome, I'm sure there is more than 1 way.

Go to Home Depot or Lowes there is a special glue in the tubes that is specifically designed for foam, it even says "foamboard" on the label. Many adhesives actually eat away the foam. If it doesn't say for use with foam, just test it first.

I don't like the foamboard adhesives from the home improvement stores. I have had a lot of trouble with them. The very best glue I have found for foam is Gorilla glue. You can cut it with water, in fact, it works better when wet. Use thin layers because it foams up some.

Liquid Nails Foamboard adhesive works great! However, after time it will eat into the foam and lose its holding power. Gorilla Glue is a safe bet, it is the "superglue" of foam and we have started using it almost exclusively on our foam jobs.

3M Spray Adhesive 78 made specifically for glueing foam to foam. Available at Grainger...

I use Great Stuff... you know, that wonderful foam in a can for filling gaps in walls? Pick it up at Lowe's, Home depot, etc. As long as you apply enough pressure while your piece is setting, this is the ultimate solution... and because it's foam, you can carve it afterwards. I picked this little gem up from building props for Knott's Haunt for 5 seasons.

Definitely go Gorilla - we've been doing a lot of large foam movie props and it bonds without eating away the foam. Just remember it foams after application, so slide the pieces around a little to break that down. Foam - the other white meat!!!http://www.xscreamhalloween.com/images/porky.jpg

Spray adhesives work great. Fast no mess! Liquid Nails even. But spray adhesive is the way to go when glueing foam!

Guerilla Glue. This stuff is great! It works on almost anything you need to bond anything else to. Plus a little goes a long way.

Do NOT use Liquid Nails, even though it says it's for EPS foam!! I made a facade for my building 18 months ago and it has begun to fall off. Where there used to be glue there is a hole in the foam. I had given it a 2 week test to be safe, but how can you test something for a year or longer? One of our customers had the same thing happen with 3M Super 77 Glue. It took 2 years to eat the behind out of his outdoor sign. A glue manufacturer that we work with said that it is the solvents in the glue or paint, usually made to quicken the drying time, that are the culprits.
I had also made an EPS foam tombstone for shows. I had tested a spray paint. It was fine for the 18 months, but on the second year while packing it up I found that the paint had dissolved the foam in many places, leaving a thin layer of nothing but paint.
On the other hand I have had outdoor foam elements and signs hold up for many years with a good outdoor latex paint.
Two part epoxy (never resin!) is a great permanent glue. I also have a proprietary glue, plus a sticky foam coat formula that have absolutely no solvents.
