gotta do some kitchen floor screeding over an unlevel concrete floor, about

Baten's placed level around the perimiter, fill with screed tamp down
well and if necessary work over with a float, prolly not the correct
way but worked for me :-)

Plus mix all the screed EXACTLY the same, and keep it fairly dry. Wet
screed cracks and slumps.

Possibly stupid question, but presumably 'screed' in this case is not
what is sold as 'self-levelling floor screed', in which case what is
it? A product? a specific mixture of sand, cement otherstuff etc.?

Screed is a weak mix of sharp sand and cement and a little water. I
think about 4:1 sand/cement

Its main claim to fame is that it is cheap, and holds its shape well on
drying.

It's worst features are that it doesn't self level, is weak, and porous.
