Painting an uneven concrete floor?

[MisterBoy]

I have a concrete floor in a Victorian brick greenhouse I am renovating to a sort of garden room and was going to paint it with garage floor paint, however on closer inspection it's a bit more uneven than I would like.
I thought I'd lay some self-levelling compound first but the garage floor paint I was going to use (https://www.toolstation.com/ronseal-diamond-hard-garage-floor-paint/p32891) specifically says it isn't for use on self-levelled floors.

I specifically want a floor people can come in with muddy feet from the garden, and get washed easily so is self-levelling going to be a problem, or do I just need a different paint?

Also, there is a bit of damp in part of the slab where it rests on soil, will these sort of paints cope with that? I already treated the walls with tanking slurry and the edge of the floor but not the whole area.

Use a different paint. Pretty sure I used the Leyland stuff on a concrete floor with slc patches, its done 8 years now with no major issues (not heavily trafficked though). The damp percolating up into the slab may be a problem.
Suggest big doormats (like the ones you get in shops).

I did wonder if the bigger issue with DLC was that it doesn't work well under heavy load - not an issue for me but I'll look at a better paint anyway. I feel like the paint itself would be waterproof but my worry is it might detach from damp concrete. I could possibly do a sealant first and paint on top, though I do see now you can buy combination DPC/paints, seems like "epoxy garage floor paint" is the thing I'm after. Pricey though. BlackJack is cheap but not suitable to walk on, I would have to cover the floor after and initially at least, I don't want to add a flooring.
