I am sure someone has figured out how to glue styrene sheet stock to pink insulation foamboard. I would appreciate the secret. For me the quicker the joint cures the better such that there is at least 10 seconds to position the parts properly.
Why are you doing this, and how large are the pieces being attached?
I’d recommend Aileen’s Tacky Glue. It’s a craft store product, and it’s pretty cheap. As long as you clean the tip off and keep the cap on, it lasts a long time, too. For very large surfaces, white glue will work, too.
Aileen’s doesn’t really bond with either material, but if you’ve got a decent amount of contact space it will hold very well. You’ll have plenty of working time before it sets as well.
I plan to simulate a concrete wall with the foamboard and add some wall detail with the styrene due to its stable dimensional characteristics. The foam works well for abutments so I figured it would work for my wall nicely but it needs some decoration
I’d skip the foam altogether and use styrene. It’s cheap, easy to use, and bonds readily with solvent-type cement. Most of mine is normally hidden behind nearby structures, like this…
…but here’s a behind-the-scenes peek:
I used .060" sheet, available at plastic suppliers in 4’x8’ sheets - I’ve almost used up five of them. [swg]
I used .030 styrene for my concrete roads so that I could paint and model cracks, stress joints and patches before I glued it down. I used water-based contact cement on both surfaces and it worked great. Woodland’s Tack Glue also works.
Probably a polyurethane type glue would be the best, altho there isn’t any type that I am aware of that will do a good job on both surfaces. What ever you use, scuff the plastic to give it a little tooth & enhance your chances of a strong joint. jerry
Here’s a not obvious selection. Try using 3M 77 spray contact adhesive. If you spray it on the styrene and then move it immediately to position it, it stays real sloppy at first so you can reposition it for a few seconds after contact.
The use instructions for 77 say to give it 10 seconds before tacking together, 30 seconds if you want an extra strong bond. But if you wait 0 seconds, you can use that 10 seconds to move it around by sticking it together. Get it on a little heavier and the time is a little longer. This basically depends on moving it around before the stuff that makes it fully liquid evaporates. Gotta be quick, but it works for me.
