I’ve done a load of dot n dab boarding in an old property I’m doing up .Regrettably it’s been a couple of months since I did it and due to illness it’s not been skimmed yet ( I’m not doing that ) .The property has no heating of any kind and I’ve now got black spores or mould showing up where the dabs are both on some internal and external walls . What can I use to get it off I presume it’s just the lack of any heating that caused it or is it likely to be something else, thanks
