Plaster cracked on every joint on ceiling!

[tolly123]

Hi, im just doing up the bedroom on a house we've just bought. After taking off the paper on the ceiling every single joint in the ceiling plasterboard has a hairline crack! House built in the late 50's. On closer inspection the PB was only tacked on with nails and has hessien scrim tape so i assume its the original ceiling. Idealy i dont want to overboard the ceiling as i know i will end up doing the same in every room through the house.

Is there any way of fixing it like scraping a V out the joins then filling or is it really a waste of time on a ceiling that old? I was thinking of doing the above and then finding the joists and screwing every 400mm.

Thanks in advance,
Matt

take it your going to skim the ceiling.
tap in all nail heads to just dimple, dont break the board paper. after checking for cables behind the boardthen screw up all joins an edgeswith matched screws.
then tape and 50/50 pva twice and skim.
