Is there a product that keeps mould from growing on inside walls?

[linspins]

Mould seems to be a big issue this year in our house, strangely more so that usual and I don't think we've changed our practices. We have a bathroom and kitchen extractor fan, and tumble dryer, but I know it's inevitable that there will be moisture in the air (not least from the humans! ). This condenses on certain cold walls, and is getting very mouldy.
It wipes off fine, so far, and I know I need to keep on top of it. Is there a product that I can wipe/spray/paint on, that keep mould from growing? At least deters it a bit?
On one ceiling we have anti mould paint. Calling all mould repellents!

do you heat/ventilate?

Following as I too have the same problem

We have central heating. I do admit I'm not good with ventilation, as the whole family gets up and goes out early for work and school, and I never get round to window opening, as I wouldn't have time to shut them before we all leave. If I am ever home on a sunny day, I open for a blast of fresh air.
Would it be worth leaving the bathroom extractor on all day with the door open?

can tou try making it your routine together with teeth brushing? something like open all windows-brush teeth-close them all again.

Damp seal will do it. But you might benefit from a dehumidifier too

Yeah a dehumidifier stopped this for us

you need to open the windows for a few minutes to let out all the moisture, plus wipe down the window condensation, squeeze out the rag and put it outside to dry.

anyone tall enough to reach needs to get involved.

We have this really badly in our house at the moment, especially where there are cold spots in the walls.

I've spent ages steam cleaning it off and sponging it down, then letting that area dry out completely.

Alternatively, Flash do a product called 'Mould and Mildew Remover'. It stinks to high heaven but does the job.

Anti-mould paint keep it at bay better than normal paint but don't keep it away for ever.

Thanks everyone! I will make more effort to open wondows. And tackle to mould with one of those products. Weird how it's so much worse this year. Things around the house have been going mouldy too, like coats on the coat hooks against the wall in the hall, and books in the downstairs loo. I hate mould!!!

Mould spores are everywhere, in every home, in every garden, on your skin and in your hair. Wherever there is dampness and warmth, they will grow. You need to reduce the humidity in your home.

In UK homes, the biggest source of condensation, damp and mould in UK homes is wet washing draped around and hung over radiators.

Opening the bedroom windows every morning between throwing off the bedclothes and leaving the house will reduce the moisture content a lot. Running the bathroom extractor during and after use will also cut moisture.

Outside the heating season, you can leave the loft hatch open, and it will encourage airflow up and out. If like me you live somewhere sunny, it can also prevent the house getting too hot in summer.

Thanks piglet John. I know about your crusade against wet washing...not guilty of that here!
But could open windows more.

I used to have this in my old house. Opening windows every morning, drying the windows and using a dehumidifier worked a treat for us.
The dehumidifier was £100 from an eBay shop 4 years ago and is still going strong!

Do you have any fireplaces bricked/blocked up? Ours was in the lounge with no ventilation. Getting it opened up again solved our problem.

Sadly no chimney breast at all, the previous owners took it out.
Bought the most amazing mould remover today from Robert days: kilrock blast away mould brush on gel. Nothing else has shifted the mould stain on the window sealant, but this made it all white again. Seems it'll be good for window and bathroom sealant and mould stains.
Was most alarmed to find water condensed all over one cold section of the roof today, in the loft. Will now check that the bathroom vented duct hasn't got damaged and is venting in to the loft space. Never had condensation in the loft before, in five years of being here.
Opened the windows lots yesterday and today, as was home. Bit chilly!!
