The first step is to prevent the plasterboard from moving, this is the reason you have the crack in the first place. I chose to re-fix the plasterboard to the joist using plasterboard screws.
The next step is to rake out the crack to ensure the new filler has a sufficient area to bond to, I did this with a decorators multi tool.
The next step is to fill the joint, I chose a combination of 2 part wood filler and lightweight filler. Both these product are easy to sand but just be sure to remove most of the excess filler as this makes sanding so much easier.
The next step is to sand the filler, I started with 120 grit and worked my way through the sandpaper to 240 grit to ensure the finish was really smooth. Try to sand in different directions as this will ensure the ceiling is perfectly flat.
Once your happy with the finish you can finally paint the ceiling, I chose to use Dulux trade super matt emulsion as this has excellent coverage.

Really useful video, especially the information on the different types of filler, and the right one to use for a robust repair. Other videos don't mention this or suggest mesh tape, requiring more work.

The best advice has been waiting for a very long time.

Really brilliant information

I would not recommend using wood filler for this job. Instead, use pre-mix for ceiling crack specifically plaster ceiling then let it dry overnight, sand it then another layer, sand it then prime and paint. Longer time but an effective for killing such crack

No. V the cracks good fix back with plaster board screws to help solve the ongoing vibration problems also good... Put 2 pack epoxy filler as a filler for a plaster board joint no it's too brittle will not last and emulsion paints do not adhere well to epoxy fillers as they are not porous.......v cracks. seal cracks with diluted pva twice mix plaster board joint filler with diluted PVA apply to crack and allow to soak in to crack fill again to be level with surface... Then for a professional job apply a good quality fibre tape over the joints and apply and feather out 2 to 3 coats of plaster board(dry lining finish) so the repair is reinforced and invisible it's a fair bit more work only a little bit more skill but you will never know you'd repaired it in the first place and should stay crack free for a long time.. In short do not use 2 pack fillers to ceiling or wall cracks it is too brittle

What size screws did you use? Thanks!

Why your not using tape ?

Using the wood filler is bad idea. Here’s why. The wood filler dried solid. As the case is with crack, you need something that is a bit flexible so when it expand it can filler the gap nicely. Really your best option is flexible chaulk or filler
