flaky ceiling, but plaster good

[prawnstar]

i've just removed the polystyrene ceiling in my house, theres no glue up there just the paint over the plaster has come off in bits all over the ceiling,
what should i do next to get a smooth or lightly textured ceiling?
thanks

Fill & sand all the chipped areas. but you still may not get a completely smooth ceiling straight away and may need to repeat a few times. Try getting some light shining at an angle on the ceiling, this willl give you a better indication of how well you are doing.

Avoid any emulsion with a sheen to it, this will highlight any irregularities, matt covers a multitude of sins!

Other than that, you are looking at lining paper or even skimming if its really bad
