Hello,
I moved into a 1930's house 4 weeks ago and have a mould problem on the bathroom ceiling. It is worse in the corners - thick black - but has spots all down the 2 outside walls.
Before I found out it was mould, I cleaned it with soapy water but this came back worse a day later.
I then used a damp fungal liquid which cleaned up about 90% of it, but it all came back about 2 days later.
Reading other people's posts, I think I need a good extrator fan (recommendations welcome, I have none at the moment) and to leave the window open while showering.
I think I need to re-use the fungal solution AND THEN to re-paint with mould stop paint.
But this will just treat the visible mould, what about treating the cause so it wont come back? Apparentley this stuff is toxic and I have a 14 month old boy sleeping next to the bathroom.
Any advise would be great. Ste.

An extractor fan is a must, sorry I can't recommend a particular one but there are plenty to choose from. The centrifugal ones are normally pretty good.

You can remove the mould, once the bathroom is dry by using some fungicidal wash, make sure you read the instructions before use and wear the recommended PPE.

When that has dried you should be able to paint over it with some mould stop paint.

Thanks for the advice. This may sound silly but how long should I stop using hot water in the bathroom for it to properly dry?
Also, if I am just treating the surface, wont the mould still be inside the walls? If so how do I eradicate it completely?
Last question - would using the fungal liquid and paint BEFORE i get a extractor be wasting my time, ie , get the extractor fan before treating the mould?
Thanks

Don't stop using hot water, just get the extractor fan fitted before you attempt to treat the mould or you will be wasting your time.

Normally the mould just sits on the surface and can be treated with the correct fungicide.

Thanks for your reply. I will buy an extractor fan before removing and painting the mould.
Now that you have answered my post, as an additional, should I use a de-humidifyer to work alongside the fan / help in winter months?
Thanks - Ste.

A dehumidifier will certainly help.

Is there a radiator in the bathroom?

Hello,
Yes there is a new one (with a grill on top) but it's only warm at the bottom. I have tried to bleed it and smelly air has come out - then nothing, not even water. Also there is no blinds for the window, someone said that having blinds would keep the heat in.
Thanks -Ste.

A smell of rotten eggs when you bleed the rads could be corrosion, it would pay you to post a question in the heating forum, detailing the system, make/model etc.

Thanks.
I will post another about the corrosion when I find all the details.
Who knows where that will lead to.

Hi Meds,

As has been said you need to do all you can to reduce the amount of moisture. It is a good idea to use a squeegee to pull the water off the tiles and screen after showering. Another help is to use a flannel to take the worst of the water off your body before towel drying. Wet towels will release moisture as they dry as will water on the shower walls evaporating.

It is hard to eradicate mould and you will have to persist with the chemical treatments. This is a very good product http://www.homecareessentials.co.uk/aca ... Spray.html

There is one to wash the ceiling with.

Hello,
Just a heads up to close this post in-case anyone else is in the same position.
I still have not got an extractor fan - but it's still on my shopping list.
Now when we shower we use a sponge (squidgee would prob be better) to wipe down the showering area, then we use a de-humidifyer (£70 focus but it's a big one and a smaller one would do the same job). As a guide I just run my hands over the tiles and if they are dry I switch it off (usually after about an hour).
The mould has not come back yet.
To treat it, we dried the bathroom then used bleach on it, horrible job, you can see the stuff come off. Then we used an anti-mould paint, 2 coats and so far it's all working.
We also have the window slightly open when showering but shut it when the de-humidifyer goes on.
Thanks everyone for helping.
