Thanks, I will get some of this Dettol Mold & Mildew remover and give it ago before painting the ceiling. And take it from there if it comes back.

Dettol mould and mildew remover is bleach with a nice smell .(1)
Save yourself some money. go bleach 1st, then treat

+1 for lakeland mould remover

As also stated you can get mould proof paint to treat the ceiling, though this could be trapping a damp problem in the brickwork depending on the source,

Really the room need an extractor fan fitted or proper ventilation (windows open). Mrs reg keeps all the windows open in the house even if its -5 outside (as it was in edinburgh this last week one morning). our bathroom has this issue and i think it wold be solved by an extractor though i have nowhere easy to install one. The mould in our house is entirely my fault apparently .....I keep the window shut when showering but mrs reg says im a coward for not being able to stand naked in that room with a -5 degree draught coming through an open window onto my wet skin.

My PVC windows have this air lock feature thing (don't know it's proper name) where I can open the window a tiny tiny bit and be able to close the handle again. Would this be good enough for letting air in?

That's what I thought until I used it. I tried bleach on the persistent mould I had and it did nothing at all, didn't touch it/fade it whatsoever. Also if you think the Dettol smells nice you've a strange taste in smells, it smells very strongly of chlorine, at least it's an incentive to ventilate more I suppose!

What do people do about condensation anyway? Do you really all sit there with the windows open and the heating on? I find with the windows open it may clear on the windows after a few hours ( I wipe it up with a towel instead) but only once the temperatures equalized with outside and then it just comes back when you close them.

Imagine standing on a ladder leaning back applying bleach to a ceiling, very dangerous, likely to end up in hospital with bleach in your eyes. Treat the cause

If you're doing it like that, I should think it would be, where did you learn that, Mr Bean school of home improvement? How do you paint a ceiling without blinding yourself?

Unless you live in a cathedral, just spray at arms length and not directly over your head, at an angle, maybe wear goggles and a gasmask and a hazmat suit?

Also even if you treat the cause, you're still going to have to do something with the ceiling unless you like the patchy black look.

So you are now advising spraying bleach at a ceiling in the home:eek:
That's unsafe advice and you may want to reconsider your post.



IE. Next topic from the OP;

"Following advice on here I have successfully killed the mould in my house. Unfortunately in the process I have bleached the curtains and carpet, the black cat now has white spots too"

Eric, I'm also unsure whether your comments about wearing goggles, a gasmask:eek:, and a biohazard suit:eek::eek: are entirely serious:D

With all due respect, suggesting a dehumidifier as the first solution is ignorant or lazy and wasteful.

Why is it wasteful? Condensation and mould is often if not usually a sign of poor insulation causing cold surfaces on which water vapour condenses. So you're wasting money heating your home only to have the heat escape easily. Then when mould forms you use more expensive electricity running a dehumidifier to fix the problem!

The first thing to do is to find out why that surface is cold and try and fix it.

In my home I had a problem with condensation and mould on the window reveals. I found they were cold as there was no insulation behind them, the only thing separating the room from the outside air was 15mm of timber. Once I'd insulated behind them with expanding foam the condensation problem went away and my nice new paintwork on the reveals has been completely unblemished by mould over the past two winters.

Obviously expanding foam is no good for a ceiling, but check the insulation up there. Is it thick enough? Are there gaps?

Well yes as the stuff I recommended comes in a spray bottle, I also suggested covering the floor directly below so that you don't bleach other things.

Of course I was serious about the haz-mat suit, how else will you protect the brand new Gucci suit you always wear when doing home improvements?
Oh and you should probably get some tiny gas masks and goggles for your baby quintuplets who simply always play at your feet while you DIY.
Oh and perhaps drape a dust sheet over frail old Grandma and her favourite chair which is obviously directly under the problem to be treated.
Oh and perhaps cancel the coach tour of your house for the blind you were expecting that day.

I guess everything's dangerous if you've got no common sense

Nah, I favour just letting Darwin take his toll;);)

[FONT=&quot]The above mentioned methods are all quite good but can’t give a permanent solution. The mycotoxin produced by black mold are neurotoxic ie can kill neurons in the brain and impairs a person’s mental ability. So it’s very essential to remove it fully. Recently we’d air quality test and mold removal by Healthy Environmental, Ontrio and the guys work were really good. I’d tried various methods to remove mold but couldn’t bring any lasting solution, at last those professionals had done it. :T.
