Airline crack, annoying little bast&£d

[Joz]

Just recently plastered a living room ceiling 7mby4m it originally had a dividing archway that was removed.
Anyway i plasterboard the archway gap. Taped the joints, pva the original plaster. 2 coat skim full ceiling. (had no heating as rads were dropped).
3 weeks later radiators back on and a airline crack has appeared were the arch was. Do you think its heat and movement?

Airline crack? Was it British airways or some foreign airline?
On a more serious side fibre tape seems to be quite crap now

Could be either .nothing easyfil won't cure

Emirates i think . New phone apologises.

I'v tried easyfill 20 but its come back again. Also doesn't help have led lights beaming down the ceiling.

Just open the crack up a bit and fill it or if it’s really hairline try painting it over see if it hides it

Should've tacked the whole ceiling over, overlapping where the arch was

Bit expensive for a 200mm gap in the ceiling for the customer. She moaned about the money from the start anyway.

Wood fitted to every side of the fitted plasterboard in the ceiling? I always fit timber all the way around, and screw both original and new board all the way around. I also seal the board edges with Pva both original and new. Tape and skim. Done this for 25+ years with no problem. If you don't this happens.

Bendy upstairs floor?
Had a similar thread last week? If there was an arch there, there's pobably a 3by2 supporting the entirety of the upstairs above it.
Like joz says, overboard entire or Wayners crazy nogginise/plate it to death. Sounds expensive but if cost is to high then walk away. At least then you don't have someone screeching at you and telling everyone that you're a shite plasterer (not that I'm saying you are, or that she is...)

Did you use paper tape over crack,,, I have stopped using fibre over any large cracks as they can re appear as said in other threads.

To be honest I haven't used paper tape.
Will try this method next time.

Try putting 2 pack filler in the crack the decorator I know says it'l never crack again might be the quickest fix for u but if the joists are bouncing gonna be hard to stop
