Hi,

I recently had a room plastered in my flat.

Before it was plastered, I noticed some white fluffy mould like stuff
on one of the walls.

I cleaned it off, and used at 4 or 5 coats of mould killer over it.

It took a while for the plasterer to come round, and I noticed the day
before he arrived that this mould like stuff had re appeared.

I showed it to the plasterer, who said, don't worry, he'd clean it off,
and when unibonded, and skimmed over probably wouldn't re appear.

However, the next day this stuff has appeared on the new plaster.

I've had a chat with next door, (i.e. the other side of this wall).
They have a built in shower on that side of the wall. - they suspect
maybe the pipe feading the shower is leaking - they've been very good,
and are going to sort this out ASAP.

The question is, what is this stuff on the wall? All the mould I've
seen before on walls has been black, whereas this is white and fluffy,
and has kind of crystals in it.

I've uploaded some photo's at :-

Definitely Efflorescence, mould does not sparkle.
Cure the damp and it will go away, or dry line the wall.
If it were mould, cure the damp and it will go away, or dry line the wall.

Agreed, for sure. I'm guessing someone's already told you it isn't
mould, because you mention the word "efflorescence" in the subject but
nowhere else??

Is the wall to next door solid or cavity? If the latter, it's not
likely that a leaking shower next door would make your walls damp (but
that's not to say efflorescence couldn't happen anyway.

David

Test the crystals by licking your finger then put it in the cystals and
taste your finger. If it tastes salty youve got efflorescence. Dont
worry, the amount you ingest is not going to kill you.

Either way you have got a damp problem that has to be sorted.

Good luck

I forgot to add, when you are sure the wall is dry brush the efflorescence
off wait a week or too to see if it comes back, before decorating

Take a good look at *all* walls in that area, because damp can enter at one
place and appear at another.

effloresence undoubtedly.

It will go when th edampness is sorted.

No point in decorating until its dried out though.

Nice one guys.
I'll wait for next door to fix the leak (or whatever else is causing
the dampness), then I'll scrape off, wait a few weeks and then
decorate.

Thanks for your help.
