OP, this is how I’d do it. Everyone’s got their own way.
- apply first coat using steel trowel (any half decent at least 12 inch plastering trowel)
-immediately flatten with speedskim
- go back on with trowel, filling any hollows, tidying edges
- mix 2nd coat, repeat all above
- once it’s looking pretty flat and decent, either go on it with a plastic trowel, or spray a bit of water and use steel trowel again
- leave it for a bit
- go over again a couple of times with whatever trowel you want to finish it off
- if you feel like you’re really losing it and it’s setting too quick, go over with a sponge float, then a trowel which may get it back under control.
