Good help is easy to find when you have a 10 year old who loves to do projects with dad. She’s spreading foam safe construction adhesive ahead of gluing the foam to a benchwork section.

 

 That's some great father-daughter time.  I bet she enjoyed it as much as you did.

Then she has that creative gene.  Good to see it and the quality time had by all.   Something she will remember.  I still remember as clear as day projects I did with my dad many decades ago.

Yep.  We started our isolation protocols by building a rolling Lego storage tray that goes under her bed.  She did about half the cutting in the table saw (under very watchful eyes), and managed the glue up, sanding, painting and caster installation. She generally has about 3 craft projects going on her own at anyone time.

Anyone got any ideas in what else besides foam safe construction adhesive might stick foam to plywood?  I really don't want to go out for a single tube of adhesive ( :facepalm:) but other then a couple of tubes of half used silicon caulk and a large can of 3M Super 77 spray adhesive I don't have much beyond wood glue.

Thanks for looking and discussing.

I just screwed my foam to the plywood.  The screws can be removed if they get in the way of scenery, but they hold it well.

Well.... I hate to say that the real answer is to NOT use an entire tube like she did. Generally, when I have to bond foam to wood I just add some lines and press.

Or, alternatively, I often draw things that would be inappropriate for a young lady, Cody.

To be fair, I spread out the glue lines - she was just spreading evenly.

You can use the 3M 77 by spraying on the foam a little more distance away as usual.  Wait a few second and press on to the plywood.  This distancing and waiting allows the little solvent in it to evaporate and not slowing eat away at the foam.  As for silicon caulk I would avoid as it outgases and the gas slowly eats away at any electronics nearby.  Of course it's it's open then it might be ok.  Still I would stick with caulking that is water based.

If you don't want to go out, any chance Amazon may have some?  I've been using DAP water based kitchen/bath caulking in a tube for years with great success.  Comes in white or white that dries clear.

What @MK said.  Then go back and add some drywall screws to give it a good mechanical bond as well. If you have 2" foam, use 1-5/8" screws, that will sink the heads well below the surface and still grab the plywood, so a little surface sculpting won't run into many of them.  If you do, back it out an move it elsewhere, or use a shorter screw and drive it in lower.

Good to see the build getting underway.

I use original Gorilla Glue. Unlike the foam-safe construction adhesives it adds very little thickness. You can probably pick up a small bottle at the grocery store on your next fruitless quest for TP.

If you are going to use Gorilla Glue, put weights on top of the foam.  Otherwise GG will foam up and expand during the curing process.

He was already doing that, so no change in procedure.

I do now have better weights lines up - 3 40LB bags of pool salt!

Does Guerilla Glue actually ever successfully bond two surfaces ?

Never has in my experience... YMMV.
