Weird white webs appearing on fresh plaster

[Charlottemclaughlin]

Hello my sister and I have just finished renovating a house and are now decorating. Just discovered these weird white web like growth on ceiling and in corners if room. They're wispy and kind of fluffy and also pointy.. You could imagine them in a cave! Does anyone have any idea what they are?? We're really concerned thank you!

What room and what walls are involved?

Pics please.

Efflorescence (q.v.)

brush it off.

When it has finished drying out it will stop.

Do not apply wallpaper or vinyl paint to the wall until it is dry. Dulux Trade Supermatt is a non-vinyl emulsion that allows the wall to carry on drying out. White is cheapest but you can get it mixed to a range of 150- colours of your choice. You can use other paint or paper over it once the wall is fully dry.

Hi thanks for replying. It's in the front reception room downstairs and this room has been damp . (Though we thought we'd resolved this issue as had damp proof course injections at the start of the project). The weird cobwebby bits are appearing where ceiling meets wall around chimney breast and then it's also going down the join towards floor (of where wall and chimney breast meet) if that makes sense?
I tried to upload pics to this post but it just takes me to a create an album link - so hopefully you can access this?

John I googled efflorescence earlier and it looked like that was more like a powder. This is def not a powder but more web like and fluffy ..

A bit concerned about it all! Have paused the decorating process.

Ah think I've figured out how to show you the images!

 

[Charlottemclaughlin]

Nope it hasn't worked. If you can't see the album I made on here pls give me an address I can email the pics to?

Click: "forum information" then "forum index" and first sticky is the one.

Hi yeah I did that and made an album , but was wondering if there was any way I can put the photos into this post but it appears not.

You should be able to access the album which has 2 photos in it.

Any advice re what these weird weblike growths are and how to treat them would be very helpful .

ThAnks

Here you go...





Could it be some kind of mould?

Thanks jelly Kat!!

Yes I think it is prob some kind of mould and was wondering if anyone had ever seen anything like this before and what on earth we do with it?

So depressing considering we thought we'd dealt with all the structural and damp issues and now at decorating stage. Obviously can't ignore this though and need to get it sorted.

I hesitate to utter the words dry rot but I see you also have mould under floor, has the house been surveyed for damp rot etc?

To help any more postings, if you go to your album copy the diynot BB code in the top box, you can paste that into the post

Hi footprints
Yeah I posted about the floor in the flooring forum. Not sure how I merge the two posts.
Basically before we bought house we had one general building survey and one structural engineer survey. When we bought house we had 2 damp/timber surveys, and carried out work as recommended subsequently. No one in any survey mentioned dry rot possibility but flooring was covered in laminate at that stage.
Such a nightmare! We're the surveyors negligent in anyway? Surely as they couldn't see any of these things at that stage, they couldn't have been expected to detect it. Who do we get on now to solve the issue? Or can we do so ourselves? Surely there must be some test by some specialist that can determine for certain what both the weird webby stuff is and also the mouldy rotten stuff under floorboards? Would this be another surveyor or a another damp/timber specialist? Or are there mould specialists? Called a few people on Saturday and didn't have much luck..

Have a look to see if you can find a copper coloured "dust" around the areas of rot. And does any of the rot look like mushrooms.. If it is dry rot then it is a specialised job to sort it out. I hope for your sakes it is not dry rot,...
