Ceiling Water Damage Repair.

    I have some water damage on a bathroom ceiling that I'm trying to repair and while I've done a bit of DIY before plastering/plasterboard is new to me.

    My question is if the chunk that is missing is too large to simply fill with polyfil, etc or should I simply recover the existing plasterboard? I was going to avoid removing the damaged plasterboard and simply lay another sheet over it.

    Open to any feedback/advice, thanks.

    If its fully dried out just use a filler and sand back, it's not worth redoing the ceiling for that little patch

    what i would do is first give all the damaged area a coat of bin primer/sealer,then a thin layer of filler,until completely filled in,do the filler in stages,letting each layer to dry fully,slightly overfill the last layer,when dry sand to blend in with rest of ceiling,then another coat of bin sealer,then 2 coats of ceiling paint,job done,make sure the water stains are covered with the sealer,or it will bleed through the paint no matter how maney times you coat it

    I wouldn't use BIN sealer under filler in that situation. Is the board solidly fixed on the jointine? No harm to run a few drywall screws in on each board edge. Remove any loose plaster skim back to a sound edge. Remove dust and prime with a PVA primer. Run a strip of mesh repair tape along the joint. Fill the joint and screw heads, allow to go off and apply filler again using a broad knife or trowel. It make take 3 coats, feathering out. Depending on how good you are with a trowel some light sanding should leave you with a surface ready for primer/ stainblocker and paint. If there are problems with adhesion I've used Bluegrit primer in the past for guaranteed hold on difficult backgrounds.

    Is that a light in the middle of the ceiling?

    IMO that looks like too big a hole for filler. If that's a light, then it's going to show up every bump in the filler as soon as you turn it on.

    I'd probably buy a piece of plasterboard in woodies, cut the hole to be a rectangle, stick up a bit of new board and then fill the edges?
