My house was built in about 1979. The room in question is about 14' x 14'. The ceiling sheetrock was connected to the rafters with sheetrock nails. The sheetorck was falling down and the loose nails were replaced with screws. Question; How do I repair the nail/screw holes. The ceiling was painted with a semi-gloss paint and I understand patching and texturing the damaged areas and then repainting the entire ceiling, the repair may not hold.
