The Weldwood, is that the DAP Contact Cement?
If you are having issues with it, I've had a lot of experience with it, and I hope they can help.
Back when I made boffer weapons (kinda like Larp, but will full force hits and more of a reenactment style of fighting), which were foam-padded PVC meant to not bruise or break bones, we used the blue-camp-pad foam rolls from Walmart, and to glue it, we used cans of DAP Contact Cement.
For best results with DAP, you want to apply the glue to both sides separately, and let it sit briefly before pressing the two halves together.
You also want to apply pressure after connecting two pieces together.
In terms of gluing the foam onto the core of a weapon or shield, you want to actually rough up the surface of the core (whether it is PVC, Fiberglass Driveway Rods, or sheets of polyethylene). Roughing up the surface lets the foam stick to the core better, otherwise the Dap kind've has the tendency to peel away from the core, which is something you really don't want. Swords typically had a striking side and a flat side, if your core came lose the blade could turn around and when you swung you could really hurt someone.
I hope this helps. Most people don't know to apply DAP on both surfaces and then wait till it is sticky.
