Urgent! corner cracks and hairlines on all two/half walls

Hi, I'm repainting the bedroom to freshen up but before I do that I need to fix the cracks and hairlines caused by seasonal change movement, and I'm a novice in this area. So forgive me if it sounded stupid. I have looked up various solutions to cover the cracks, such as crown moulding, caulking etc. For caulking, which material do I use for the wall - acrylic or silicone? -any recommendations for which product/brand is best for this problem? Also, should fibreglass mesh be used for the cracks??

Best solution for cracks would be to rake them out to give them some depth and open them up slightly, then you want to put your tape on.. be it crack tape, skrim tape, fibreglass tape etc.. apply your filler on top, thin first coat then bring it out wider on the second coat giving a better blend when sanded and painted. If you were going to go down the caulking route do not use silicone, this will make a barrier for your paint and your paint will not stick to it.

Try using a drywall joint compound or a flexible polyfilla. I'd personally suggest trying the latter first though as this will more than likely solve your issue.

You can use easiefill40. This allows you roughly 30 minutes before it starts to set allowing time for you to make sur the cracks are properly sealed.
Although, the cracks appear small you have to rake them out. This will potentially make the larger so best to use a filler you have to make up and have time to play with.
This product will cost from £13-£20

Chop out cracks back to brick/block work. Apply Eml then bond over then plasterer. This will stop surface cracks coming back when movement occurs

I always use a Stanley knife and score out the cracks to open them up a bit more in v sort of shape as small cracks the filler can’t tend to cling to anything, then give them a coat of easy fill, overfilling the area, then once dry sand back to flush and once painted it will be lovely, stay away from using caulk so fill wall cracks as it can’t be sanded to a nice finish and silicone products can’t be overpainted

Filler/ caulk should so the trick but it won’t fully fix the problem. If it’s cracked before it will crack again. Don’t use silicone as you don’t be able to paint over it. Decorators caulk
