Something I can find at a Home Depot or similar store, since it’s on an asap basis….
I find answers about using Polyurethane-based glues, but no information about products that will bind Polyurethane foam well.
Hot glue is a quick but temporary solution. Because of the insulating properties of the foam the glue doesn’t cool down as quickly and gives you more ‘working time’ than hotglue normaly would.
A thin layer of waterproof construction adhesive (such as liquid nails) applied to each mating surface and allowed to go tacky before being joined works well but takes a few days to fully cure.
Of course a Polyurethane Cement will always be better.
Ring a foam insulation supplier they’ll have everything you need and the best advice.
Which hardware-store glue to bond Polyurethane foam?

not exactly sure what polyurethane foam is–can you describe it / what it’s for? maybe you could try a low temp glue gun?

A spray adhesive will work best.

Both Lowes and Home Depot carry adhesives designed to glue polyurethane insul board – I had them spotted out for a project. (in cartridge tubes)

Contact cement. You apply to both side, let airdry and then it will stick to itself without sticking to everything else.

"Gorrilla Glue" is a polyurethane glue that will weld both pieces together.
