.... before being able to skim with a self-levelling screed?
This weekend, as part of the kitchen floor improvement project, I dug out
the former hearth bed that was higher than the rest of the (wooden) floor,
and laid an all-in-one concrete mix to bring it to just below the level of
the rest of the floor.
I have some Feb self-levelling stuff that I plan to use to finish the job
so how long to I need to leave the concrete to go off before applying the
top screed?

TIA,
