All this sounds a right faff, what with different sands,lime plasticiser's and waterproofers can't you just use gypsum. Or like you say nicklearse you and a pleb on the hawk and trowel.

What you on about gypsum?
4/1/1 with feb
Did u not even get it through the rotor?
Just about nick . I got it about a foot or 2 down the hose. Think it was mixed to thick. Am doing float and set tomorrow i might try 5/1 and wetter.
How wet @bobby. Let's say if u put it on the hawk (handboard) would it be workable off the hawk or 2 wet to be on the handboard.
