    Having remove all the paper from the ceiling, I am left with some small-ish cracks - some are hairline, some a few mm.

    I've read various things online about lath & plaster ceilings, think soemwhere said best not to skim over it with new plaster as the different plaster types would lead to further cracking.

    What's the best way to proceed? Scrape out the cracks and fill them in with some plaster filler then paint?

    The best way is to remove it, very messy though, alternative would be to overboard the area.

    If the laths are anywhere loose then perhaps screw them up to the ceiling joists.

    If you only have hairline cracks then its safe enough to skim over after a couple of coats of PVA without either removing the laths or boarding over.

    What room or space is above the ceiling joists?

    I am no expert but I had hairline cracks in my lathe and plaster ceiling on my landing and all I did was fill them with squeezy pollyfilla then painted the ceiling. It worked a treat?
