Spray… cork? Is that just glue+cork bits? Does it end up airtight?

I’ve been pretty excited about steam expanded cork boards, they apparently make for excellent (albeit expensive) exterior cladding. Ditto granules for replacing attic fiberglass, though the additional weight of a thick layer seems like it might be a problem for ceiling drywall.

Oh awesome, just water based paint (20%) and cork bits (80%). Sounds like a really cool material.
