Surveyors look that closely.

Nobody wants the phrase "water staining to living room ceiling" in their HIP or Home Report......

Absolutely spot on. Anyone paying the massive cost of buying a house, who doesn't look at the ceilings is a clown . Of course your friends or neighbours don't come in and stare at your ceiling, but try explaining to a prospective buyer that "it's no big deal"!

MSE should really look at locking threads that are over a few months old...

I have a water stain on my bathroom ceiling and while it's going to be a long time before it gets far up enough my To Do list for me to be actively researching it, it was really neat to open up this thread and find the answer. I note it's risen from the dead several times since its original run.

But... the solutions to an age-old problem like this haven't changed significantly,
so why reinvent the wheel? :huh:

I never contribute to forums but often take lots of useful info from them but I felt this was important to share.

I've just painted over my damp patches in the hall after using the PVA water mix to 'prime' them yesterday and it has already started to crack as it dries

So basically wish i'd just gone and bought a primer or other product for this instead of using the PVA as i'll have to go do that now anyway..and I don't even know if it will be ok to paint over now

I'm not sure why it seemed to be a recommendation from anyone..

A water stain on a wall or ceiling is the result of iron and other stuff in the water, which is reactivated when you apply water or a water based paint, use an oil based paint undercoat first or gloss if it is a small stain, dont leave brush marks as they will grin through when you roll the ceiling.
Zinzeer stain block is the prefered method for me as it gives a flat matt finish and you may be lucky and not have to paint the whole ceiling.

we used zinsser i think it was called on our ceiling after the porch leaked, it hasn't shown through.

I second this - zinsser BIN cover stain sealer. You can get it in an aerosol which you spray on before painting. I used this on a water leak in my lounge 4 years ago and it was magic.
