New plasterboard to finished ceiling: how to avoid cracks?

[ETFairfax]

Hi,

A few years back I took a 1 week course in plastering and have since skimmed my bathroom and chimney breast with decent results (the bathroom ceiling wasn't the best if I'm honest!!).

In the bathroom I put scrim where the walls met the ceiling which as I understand it, helps avoid cracks appearing. So far so good - 3 years later and no cracks.

Moving on to the here and now; this weekend I constructed a stud wall in my bedroom which will eventually become an en-suite. I have clad the wall with plasterboard on the bedroom side and will at some point need to give it a skim coat.

However this time round I am skimming up to a lovely, flat, painted ceiling and adjacent wall. So I cant put scrim up where the plasterboard meets the ceiling as I wont be skimming over it.

My question is: What should I be doing to avoid cracks appearing where the new plasterboard meets the ceiling?

Thanks,

ETFairfax

In a circumstance like this, I've applied scrim at the join prior to skimming the wall. Then when the wall is complete, hide the half-scrim on the painted ceiling with a thin layer of easi-fill feathered out.
You can probably do the same with a bit of multi, but I like the fact easi-fill is easier to sand if it's not quite flat.
I think it is important to have some scrim place or a crack is likely.

spot on newbie easiest way i tend to do it with plaster but have done it before with easfill, and OP if its easier for you use easyfill

Put some coving up?

I think eventually I will go with TheHandyAndy suggestion of putting up some coving! But for now I'm going to give this "EasyFill" stuff a go.

Thanks for all your suggestions.
