Getting ready to finish my layout board and plan to put some 2" rigid pink insulation board down between the tracks and the plywood to deaden the sound and also to allow me to carve a river into my layout. What's the best glue to use for adhering the pink foam to plywood and also to itself for tunnel building? I know some adhesives can cause foam to disintegrate. I do need to adhere it to the plywood since this board will be stored upright when not in use.

Liquid Nails has a special foam compatible glue.Marked on the tube for Foam. However, Most times I just use plain Elmer's white or Carpenters glue.

I agree with Dewey on the Liquid Nails Foam adhesive...worked great! I didn't know about using the carpenter's glue on the foam, so I'm glad to hear there is an option.

 

Thanks!

I used hot glue, but you have to be quick about it. Having said that, it allows you to go to the next step of building your layout in minutes.

If you're going to cover it with plaster cloth like I did the other day I just used 3M spray adhesive and it worked okay. It was quick.

Wood glue works well.  I have used a few drywall screws to tack the layers together till the glue dries.  Cheap and easy.

Drew, I went back and checked out your rr, what a beautiful creation!  Man, you got talent!
As for me, i've used foam (2") over 1x4s, drywall screws and the darn cheapest white glue I can find.
Usually the Dollar store.  Works great for me!

When using stacked 1/2" foam scraps and white glue to build the scrawny"Mountain"

shown in one corner of my small 9x16 round-the-room attic layout; I pinned the 1/2" sheets with finishing nails until the glue tacked or dried and then commenced carving the foam with a serrated knife, rasp, etc. Elmers works as well as any.

I would go with the Liquid Nails (foam variety).  You can get it small tubes (very convenient) as well as the glue gun size.

I used Gorilla Glue, but it sounds like just about any glue will work. GG expands, so it's probably not good for everything, but it sure holds.
 

Cheers, Dave

Might try "Weldbond". Non-toxic. Looks and flows the same as white glue, but stronger. Try on some scrap pieces first.

I have used Liquid Nails Foam glue on two different layouts and it is good. But cheap white glue is as good as it gets for glueing extruded foam--if one has the patience to wait until it tacks before proceeding with the next application. However, you can pin the fresh glued foam with finishing nails as long as up to 16p, if necessary, to hold while you  proceed more quickly.

It helps to remove the poly skin from blue or pink foam before stacking/glueing [or painting]..

I use all the special and more costly glues mentioned for many applications,but not for foam. You better read the fine print on what you use or you may find cavities in your foam after the fact.

One more option - acrylic latex caulk - cheapest you can find. Has a little more grab than some of the other adhesives. Use those finishing nails or drywall screws too, as suggested above.

when stacking the foam pieces together I use 3M spray adhesive, it allows you to stack quickly and the hot wire cutter goes through it easy.
