I'd never use over high suction like Danny says. It will suck in like mad first coat and usually crazes....but way to get over it if you do is to keep laying tight coats over that area.
It wets it back up, then just trowel that section up earlier as you do the rest of the wall and I find that sorts it.
I think it's great for painted walls etc but any high suction areas over a m2 id just Pva and multi or bond-it first.
Once people know how to use it well it won't cause problems.
I find it perfect for over Artex, old paint and also walls with mostly paint and some old skim but not areas that have been ruffed or old skim.
