Green mould on fresh plaster

Hello all

Recently had damp proofing done throughout an old house. (1850s.) Taken back to bare wall, membrane placed and replastered. Now, about a month later I have green mould appearing in a few places.

I have contacted the company that undertook the work and am expecting a visit from them but would welcome any ideas on why this has occurred so I can be better informed when speaking to them?.

Just seen your other post with picture . Looks like a condensation issue {warm air onto cold wall} . You will need to create a thermal barrier on the walls . I take it from the age of your house it is of a solid wall construction with no cavity,. Any re'plastering carried out to your property should be done using a lime plaster so the walls can breath. This is just my opinion made from one photo and limited information . Hope this helps.

Hi Beader

Thanks for your reply. For some reason my post was duplicated, I blame my fat fingers ;)

Your reply is most helpful. Thank you.
