Mould on walls

Rambosmum

When we moved in to our current house (renovation project but liveable). We noticed white furry mould growing on the wall in our bedroom, this wall was external and the mould was caused by penetrating damp from bad pointing and damaged gutters. Both have now been remedied and other problems caused by this have been resolved (damp and blown plaster in areas etc) however the mould in the bedroom has grown back in a couple of areas and is now furrier and green (looks like what you get on bread). I've stripped the wallpaper to remove the food source but wondered if there was something I could use to treat the plaster? We intend at some point to take the wall back to brick and replaster but can't really afford to do that this year or next - it's a forever home and there are much more pressing issues (electrics, plumbing, roofing etc) so we are taking out time.



Any temporary fixes out there that will prevent the regrowth?


Edited to add: I am aware of heating/ ventilation issues and mould/damp growth and we follow those as a general thing anyway so I'm confident that isn't the issue, rather it's spores from the previous problem not having died.

In the US, there's a product called Kilz that kills mould spores and reduces likelihood of recurrence. There's a similar product here that you can use before painting over a mouldy wall, but I'm not sure what it's called. Zinsser makes a mould-killing primer so that might work. Maybe look at the active ingredients.

Bathroom mould remover works almost instantly, it smells like bleach and water, I guess that would work.

Grenage

I would simply treat with diluted bleach before repainting/whatever. Now that the damp source has been treated, you shouldn't have to worry too much.
