I've never overboarding a ceiling, only skimmed over artex. However this ceiling had coving which has been removed and made a bit of a mess. The result is some sections flaking off and some loose material.
Would you
A: remove loose material then PVA, to bind it all then mix of bonding/skim, then skim OR
B: Overboard with 9.5mm PB and skim?
