Water leak from bathroom through to ceiling below - multiple days

[Snugs08]

Got the builders  back in today, or one of their contractors to be precise, to sort a water leak, warranty, I think it's been happening for at least four days possibly since the water pump was connected 2 weeks ago, wifey has been complaining that it smells like a sewer for three days, and giving me grief that I'm wearing shoes in the house due to constant mess on toilet floor - first it was just wet and dirty so easily weird, now its all white from where the grout has powdered out  - well vindication it seems not my fault..

 

Anyway, whats the typical remediation for this, lone contractor guy left today and water pump seems back on, picture as it was 15minutes ago, concrete is still wet as it looks, and I suspect another 2sqms of wet concrete too given the grout coming out across the bathroom.. And the ceiling below?

 

Basically, just looking for confirmation, that ceiling needs replacing and to stop them if they attempt to paint over it... Anything else to consider?

 

 

 

 

 

Rotation seems wrong here, but that's the ceiling of the room below the toilet,

While replacing the ceiling may be required, first the ceiling needs to be totally dry this will take weeks to be sure it’s 100% dry unless you have airflow over the back side. Then you need to see if the board has bulged, if not and the leak is 100% stopped then paint is enough.

Likely given sufficient drying time paint will be the appropriate choice, sorry to be the bearer of bad news.

as sometimewoodworker mentioned,    firstly, you need to ensure the leak has been fixed/sealed  so it never leaks again.  Mop up every drop of water at that pipe so everywhere is dry .. dry ... dry ...  then you run your pump for a week as normal and check the pipe area again to see it's still dry.

Then you need to ensure everywhere is completely dry before painting or doing any cosmetic work.

If the ceiling is plasterboard it needs to be 100% dry and not warped from the water before it can be painted.

_{Thanks guys, fine by me if painting is actually the eventual right choice. Doesn't look like the first contractor is coming back today so I presume he's done his bit and fixed the leak but it is exposed so probably he's doing the wait and see thing, will find out more from the builders on Monday I suspect and watch for warping and bulging. Welcome to Fawlty Towers will be my house sign..}
