Anyone used this? It seems to have advantages over normal plaster in
that you can take your time and just use what you need, plus you don't
have to seal the surface. If you can apply it 2" thick there must be a
very lightweight aggregate of some sort in there.
What I'm wondering is whether a skim of this stuff will polish up like a
finishing plaster. Not that I've ever managed to achieve that kind of
finish, but I can dream.
