As yall can see in the background, I have an extensive collection of mostly Plastic SpaceMarines. I have several 8fluid ounce bottles of Elmer's Craft Bond Tacky Glue, but that is the only glue I have that is safe to use on Styrofoam. And there's gonna be alot of Styrofoam to glue together, stuff to glue onto Styrofoam and stuff to glue onto the wooden board that is the Foundation.

I'll need a texture paste of some kind to make the styrofoam&wood blocks have the texture of "futuristic super concrete" that won't add so much weight that this small board won't break super easily. The board is 17.5"×32.25"×0.1" and is an unknown kind of product made from wood I think.

I'll also need a paste to make the ground around the wall look like dirt.

The glue I use for my Models is Tamiya Airbrush Cleaner[works about as well as their Extra Thin Plastic Cement&is much cheaper] and Gorilla Glue SuperGlue Gel. I know that SuperGlue in general just melts styrofoam, and I've never tested the Tamiya on styrofoam. I already know the Paint Brands I'll get Paints from and can definitely source all the parts I'll use to make it look more like a properly armed Outer Defensive Wall, it's just the glues&texture pastes that I don't know what would work best, and I'd appreciate any advice yall could give for making the styrofoam blocks sturdier(would sticking some toothpicks and/or straightened paperclips be worth it?).

I am planning on mostly keeping this in my House, but I will definitely want to transport it to&from a few other places local so I'll need to design it to survive being transported by car. And I'd not be surprised if I would want to take this with me whenever I have to Move somewhere else to live than my current Home. Maybe making it to I can take the Styrofoam Walls apart into sections would help with that? Would also make Painting easier, but it'd be tricky to make the Wall segmented like that given that the core is just the stiff Styrofoam that often comes in the packages for TVs&other large, sensitive Electronics.
