"How to glue Styrofoam/green board to wood?" Topic

I have a wonderful, baked, piece of semi circular pine bark that I would like to use for a mountain scape but I wonder what would be the most effective way of getting the wood to adhere to a styrofoam/green board sandwich. Suggestion? Thank you in advance to this sticky situation. Okay sorry about the last. H

I would suggest carpenters glue from your local hardware store.

A hot glue gun would probably work. But I don't think it be very stable/secure.

Elmers Wood Glue or Gorilla Wood Glue.

Aileen's Stretchable Flexible Fabric Glue. Just need a thin film between the flat surfaces, let dry until set, and you'll never be able to peel it apart… ;-)

3M Styrofoam Spray Adhesive.

I've used it for 20 plus years, will glue foam to foam, wood, plastic sheet, metal. Spray both surfaces, wait a couple minutes until it gets "aggresively tacky" and carefully align and press the two pieces together.
Wait ten minutes (or less), then continue working.

It sprays out in an almost stringy kind of pattern, not a mist, so you don't get a ton of overspray, but take care to protect your work surface. I use old newspaper, let the adheive overspray dry, fold up the paper and use it again next time.

Liquid nails

If I understand what you are doing:

I would drive a few finishing nails into the wood base as mounting point, cut the heads off if needed and then use a foam safe construction adhesive like:
LOCTITE PL300 Foamboard 10-fl oz Construction Adhesive
or
Liquid Nails Interior Projects & Foamboard Adhesive LN-604

These are caulking gun type glues, if your project is just too small to justify this, there are other option. I suggest Original Gorilla Glue (an expanding urethane based glue) but here are more options: link

Thank you one and all. If I end up not making a botch I'll post a photo. H

Titebond Carpenter's Wood Glue

Note on Hot Glue… Use Low Temp Hot Glue only, on foams. The High Temp Hot Glue will melt pretty much any foam.

I've used the Low Temp Hot Glue on many a piece of pink insulation foam, to bond crumpled brown paper sack material to it; the crumpled and flattened paper created a chiseled wall texture, as if the foam were a mine cavern wall section. Never had any issues with the Low Temp Hot Glue melting the foam, or bonding the paper to the foam.

I did, however, apply Minwax Polyurethane Stain to two paper-covered foam pieces, after they were properly painted, and then I baked them at 170 F, in a slow cooker; the Low heat setting is 170 F. I was attempting to speed cure the oil-based Minwax. The pink insulation foam melted away from the paper, along with the Low Temp Hot Glue, ruining the pieces.

The Low Temp Hot Glue melting point is lower than 170 F, and it holds very well to many things, including plastic figures such as Army Men. Army Men figures are made of a type of plastic (polyethylene?) that almost nothing sticks to, but Hot Glue sticks -- very well! Cheers!
