Will it stick? I know it's probably designed for bonding but I don't really do plaster. I was thinking some SBR slurry brushed on then a thin first coat?
Is this outside or inside? Is it going to be a habitable space? Why not plasterboard foam glue to the PB or Insulation board. It sticks to anything, pretty much.
