Have been asked to skim over a small artexed ceiling. Yes I will PVA then a bond coat first. How soon after the bonding coat can I multi-skim over. Also should I be using one or two coats of bonding.(A fairly deep pattern) Just one other thing I have some unopened plaster which is a few weeks out of date. Would this be OK to use, or should I just get a new bag?

Let the bonding coat set/go off. You'll see it darken/change colour. It'll take around an hour n half to 2 hours or so, to set completely. Don't put the multi on before the bonding sets properly, or you'll end up with masses of blisters, which are a pain to flatten. I'd put 2 tight coats of bonding on,,, one after the other, from the same mix if possible,,, that way it'll set at the same time. I quite often use bonding plaster from B&Q, which now and again, is a few weeks out of date. Being kept in that dry environment keeps it ok, but if it's been kept in a damp shed/garage for too long, then forget it, and buy a new bag. Personaly, i don't mind if the out of date plaster goes off a bit quicker than normal, but for someone who's a novice, or a bit unsure, then maybe better to buy a new fresh bag.
If it's small and easily managable then the old plaster may be ok, or perhaps you like a challenge and wanna see how fast you can work? for a fiver I dunno if it's worth the greif to be honest?
