Spores appearing after newly plastered wall

Why not?

Loving how some of these conversions go!

So in answer to some of the questions...

• While the builder bought the Celotex boards, I am fairly sure that these were bought from trade at the time he needed them. They were sat in the garage for a couple of days before use and looked brand new. I have pics of these somewhere too.
• The order of doing the conversion was a bit back to front as they were trying to complete before xmas, so that wall and a couple of others were plastered while the garage door was still on, so was cold with no heating for a couple of weeks. So @worthwoods probably has it right.
• It's all the way down the External wall, not just at the window end. Worse at the joins.

I have wiped down the walls with mold solution and prepped ready for painting. I am going to leave a few days to see if anything more comes out. The heating has been on in that room now for a good couple of weeks so the room is now aligned with the rest of the house.

Thanks all for your feedback. I will report back at the end of the week in hope it helps anyone else.

You snob, we use empty bags!

Should use one with a little bit of dust in the bottom of it. Just make sure it goes straight in the skip and not in the mixer.

That's part of the new @Stevieo range at IKEA.

It does not look like salts. you would usually get a white powder appear on surface.

We did the same thing when we had similar problems with the wall. And it worked.
