mould growth on newly plastered walls

selfbuildsoon

I've just noticed some mould growth on walls which have been scratch coated and skimmed about 3 weeks ago. House is airtight and windows have been open on latch but obviously need to open them fully all day from now on. My question is if this will go away if it's cleaned off? Have read about using vinegar but am wondering is this safe on newly skimmed walls?

There is a lot of water in the house from the plastering process, the house needs to ventilated fully all of the day long each day until your heating is put on and then until all the condensation goes away. You could also use a dehumidifier on low to help.

You should be able to wash off the mould with a dilute solution of vinegar and water but there is no point in doing it until the ventilation and heating are sorted out as the mould will return until this is done.

We have the exact same issue. House plastered with about 4 weeks. We've been opening the windows every day. We wiped off the mould with bleach today. Hopefully it'll do the trick.

Bleach seems to have done the trick for now. Hoping to have heating up and running in 2 weeks anyway, which should kill it off completely.

heating is good, but again, heating water creates condensation!, so airing the place is every bit as important as dryinging it with heat....ullg et there, dont panic!

between plastered walls and floorscreed its amzing the amount of water thats going in there
