Foam Boat Building: Best adhesive to use with polystyrene foam?

This is an adhesives test with 4 popular adhesives. I'm using XPS polystyrene foam from Dow (blue board) and Owens Corning (pink panther). The pink foam is more spongy and softer and as such is not recommended for building boats. The Dow Styrofoam brand blue polystyrene is by far a better product in my opinion for building foam core boats. So which adhesive works better? GREAT STUFF! Hands down it has the strongest adhesion and is the least expensive. All the other adhesives I used (Gorilla spary adhesive, 3M Super 77, and 3M High Strength 90 Contact Adhesive all melted BOTH the pink and blue foams to varying degrees. All in all I'm using Great Stuff. It's messier to work with and MUST be clamped to hold it in place or it will create gaps between the foam layers. Great Stuff is less expensive, and is more forgiving allowing great time to reposition foam pieces before clamping. When clamping large surfaces just use 2x6 boards and add some weight on top. Simple. If you have any more questions or have an idea for a glue I haven't tried yet let me know down in the comments. Thanks for watching. Please subscribe and hit the LIKE button! Thank you!
