Any DIY'd self levelling screed for final finish?

We need to sort out small kitchen floor out - approx 2.5m sq - which has been bare concrete since we moved in. We like the look of polished concrete, and the concrete that's down at the moment is just unfinished/dirty/damaged as it's had lino tiles on at some point by the looks of it. It's flat/level and otherwise in good condition (no massive holes or chunks missing etc).

I'm looking at screeding it with an epoxy screed such as this: https://antel.co.uk/flooring/47-epoxy-self-smoothing-floor-screed.html

Has anyone done this themselves before? Any risks? How do you protect the kitchen/step and prevent whatever you pour down finding a hole underneath the cabinets/against a wall and sucking up litres and litres?

How easy would it be to remove the three units on the left? remove them and the right hand end panel, kick boards and run a floor sanding over the current concrete?

Not easy at all. If that was a requirement we wouldn't do it.

Epoxy is a strange choice of floor finish for a kitchen, in a garage it's ideal. I would tile it, you'll be overall happier with it. Epoxy can be tricky stuff to use also.

Problem is the area is not square at all; none of the corners are right angles and the step in particular is off by a far degree. The added small step down and the little nook and I'm worried small tiles will highlight the angles, and larger ties are more faff.

That's aside from the fact that we like a concrete finish and trying to pick tiles we like is difficult!
