Hi all,
Having spent a lot of time and effort redecorating daughters bedroom and fixing (at least I thought I had), a damp issue, are things now getting worse?
Highlighted area where damp, black mould and peeling paint used to be before decorating:
Weird furry mould (?) where there was never any damp previously. Looks like it has burst through the plaster. I scraped it out a few days ago and its kind of bursting out again!
It was spreading a bit but it looks like it has at least stopped to the areas you can see:
When I was decorating I pulled all the old sealant out from around the window frame and there were big gaps to the outside, a breeze coming through and some daylight - so I used expanding foam down all the sides and along the top to seal it, cut it back and then finished with sealant. You can see how the sealant is turning a 'plaster' colour and you can just about make out a change in colour along the top (circled) - this is almost now dripping with water - I'm hoping this is just from an inside/outside temperature change but I'm concerned I've sealed something which is stopping water running away from somewhere and its settling on top of the window and soaking through...I don't know - have I sealed a vital air cavity which keeps the temperature regulated?
I have another thread here where I used Zinsser anti-mold paint on all of the inside window section but it was a disaster and kept peeling - the coverage ended up a bit hit and miss and it didn't ever really fully take - is this damp patch circled where the Zinsser is preventing condensation from penetrating the paintwork?
Any advice appreciated, thanks.
