Damp patch on ceiling.

alanbb

Just discovered a leak in the central heating pipes above the kitchen. Large damp patch appeared a couple of days ago and I lifted the floor boards in on eof the bedrooms. Pipe joint is leaking! I have a container under it catch the water and the plunber is coming first thing in the morning to fix the joint, but I'm just wondering about the ceiling plasterboard.
Does it HAVE to be replaced? It has'nt fallen in and I am hoping I can paint over the stain after it has thouroghly dried.
I did this before in the living room, painted over the damp mark with oil based paint, then painted normally. Worked a treat, but this time the mark is much larger.

Any thoughts?

I used a mixed solution of pva and ceiling paint. It blocked the stain lovely.

Just use ordinary white undercoat paint. When dry put ceiling emulsion over it.

On a sideways but related issue - how did you repair the central heating pipe that was leaking there? From the first floor?

Edit: Having read the post properly, I see that you lifted a floorboard and then had a plumber arrive. Sorry!

You have two choices in a situation like this - lift a floorboard, or if you can't, break open the ceiling.
I'm sure there's a video on youtube to show how to lift a floor board.
