[papercreters] Re: EPS or Styrofoam, Drywall Test Blocks

I just made the mixture a little thicker and it was fine, maybe just a little more on top but not much. If it's too soupy the EPS will float. (not by experiment but by experience)

This was OK because they got mixed in when we put the slurry into the forms. I can't imagine using a lot of it though. It may be good for insulation but it may be hard to mix in in large quantities. If anyone has experience I would appreciate knowing how it works.
