Default Molding styrofoam

Hello guys, I have a couple of sheets of styrofoam that are roughly a centimeter thick and am wondering if there is a way to glue a couple of sheets together to shape/cut a fuselage for a glider. Are there any special glues or methods to use when hacking?


Thanks, Shredder111

Test the foam with foam safe CA, you can use epoxy or hot glue on some foams also.

Crossing the two pieces you already have, "a la light weight foamie" style, should make a very strong fuse........

Would all purpose white glue work?

Yes, but it takes a very long time to dry. Aliphatic wood glue (the yellow stuff) is better.

I already got the "test" block drying. I was wondering why I got such a quick response lol when I remembered the UK already has already daylight People on this site are very helpful


Thanks, Shredder111


P.S. are there any ways to get a nice finish on styrofoam and make it chip resistant?

I find Poly-c and tissue does well, not as strong as glasscloth/epoxy but much lighter.

Talking foam

Use packing tape to get rid of the chip factor, it adds weight, but it's increased durablity overrides that. Slow drying wood glue isn't necessarily a bad thing, especially for the new builder, you need that extra time in case you put something together, and 10-20 minutes later decide it's off, can tear it back apart without destroying it, that and since you are dealing with foam, water will dissolve it. I use a hot glue gun and fast drying expoxy on it, but I work very fast and loath waiting for stuff to kick off.
