Hi folks. Some advice needed please, repaired a ceiling which had a crack in it which ran down the middle width ways, in the past I have tried taping joints but not got the results I would have liked so I have been using the Dunlop deep filling compound as I find it dries hard and doesn't seem to move, anyway once the crack was racked out filled sanded and repainted everything was fine until the next day where I noticed a hairline crack had appeared, so re-racked filled sanded and painted...
