Most youtube videos show plaster being applied in 2 coats,

Can the second skim coat be applied a few days later ?

I've a big ceiling to do tomorrow and might get tired and clumsy after lifting up the first coat.

IME it may not stick.
So,
Wet down first coat with diluted PVA
Mix in PVA with second coat
