Advice on ceiling water damage please

Fi2024

Almost a week ago now, a pipe had been disconnected from an overflow tank in the attic. Water poured through the bedroom ceiling below. It stopped within a couple of hours . The pipe was reattached by a plumber. The ceiling has been left to dry since then but as you can see there is very obvious yellow staining to the ceiling. How likely is this to develop mould? Or might it be okay as it was over a short period of time? Is it plausible to simply repaint the ceiling, somebody on here mentioned stain blocker paint……..thanks

first repair the crack,then 2 coats of any oil based paint,you might have some left in a shed,or buy some,you can buy stain blocker if you want,then 2 coats ceiling/matt paint,dont think you will have any mould problems then

Test that the fixings ( screws / nails ) by pushing the slap upwards . If the integrity of the slabs are still intact , then paint with a " Stain Block " , 2 coats should suffice . Patch cracks and 2 coats of ceiling paint .

Hi!

If the ceiling has been fully dried out and any wet insulation which was removed has now been replaced, then the ceiling won't develop mould any differently than any point in the past. Yes, a good stain-blocker would be required here, a local paint specialist might be best advising on that, but there are many brands out there now. Cracks and gaps should be scraped-out, back-filled with a good filler and sanded first though.

Thanks. I hadn’t thought of whether there’s insulation in there or not. The ceiling remains intact………..
