Just did a ceiling today with a 600mm SpeedSkim.

I wouldn't know where to start with a ceiling.
I'm just painting over the Artex at the moment but the downstairs loo would be an opportunity to try.

With a ceiling, start at the top and.... .

So that's where it is 😀
It's probably the corners and edges that I'd find tricky. The finishing trowel leaves a line in the plaster. 
A review of the SpeedSkim mentioned that the corners of the blade would do this.
Helps to round them off.

Got one corner that is causing a problem. Rather than trying to fix at the time (plaster was going off), I decided to leave it until I do the walls. Will hit it with a corner trowel. The edges are easy enough. Just run a wet paintbrush along the junction a few times as the plaster is going off.

The blades on the SpeedSkim come with rounded corners. The early model were square, but feedback from the professionals persuaded Ox to make the change. If you do get a line, it is (usually) easy enough to remove with the finishing trowel.

Is it a plastic blade that's supplied? There seems to be different ones available including stainless.

Ah, had forgotten about the S/S blades - The SpeedSkims I have are fitted with plastic blades. I presume the S/S blades are for your finishing passes.

I'll probably just go with the plastic one. Says it's for finishing.

Not too bad for first attempt.
Hard work and messy job but should be a bit easier on the other patches.
Need to work quite quickly as the plaster starts to dry out. Garden sprayer is useful.

I used a length of angle alloy as a straight edge to level against the old plaster. 
SpeedSkim 600 for finishing.

Looking good so far. You can always use a skim or 2 of Knauf fill and finish on any bits you don't like, and for feathering in the edges if you can feel the join.
If you can feel an edge it'll show when it's painted.

Extratime is handy when you have a big area to do. But for a small patch like you are doing, it shouldn't be necessary.

That might be a problem. The edge of the new plaster is slightly raised in areas. 
I'll try sanding it to blend in.

It's easier going over the edges with a filler that's sands down to nothing to get a perfect join. Worth spending a bit more time on the prep to get it right. You don't want the patch showing when it's painted.

Do not try sanding multifinish - It goes off rock hard, the dust goes everywhere, and you don't want to breath it in. Your two choices are to either give it a coat of Fill & Finish and wet sponge sand it, or to skim the whole wall.
