Do I have to use liquid nails or Loctite to glue the Styrofoam pieces together? Or can I use a different type of glue?
It doesn’t really matter what you use for the gluing of the Styrofoam stage, (you could use toothpicks) you’re just trying to keep it together enough for the many layers of grout to be applied. It’s really the grout that is holding the project together in the end. Products like Loctite hold fairly quickly so that one can progress faster in building their project. But, like I said any type of adhesive can be used,for example with the Castle project I ended up having to use mod podge -which is essentially the same as Elmer’s.
