Prevent mould on Bathroom ceiling

big_mortgage

Hi

does anyone have any ideas on how to stop it? I have repainted ceiling now several times. The trouble is the window is not that high up so the steam doesn't all escape.

any products out there to prevent this?

thanks

Hi Big Mortgage,

1. You could turn the heating up in the bathroom so the differential
temperatures of the ceiling surface and your hot water isn't so great as to
cause so much condensation, thence mould.

2. Leave the bathroom door and window open after you've bathed/showered
so the moisture can dissipate as quickly as possible.

3. Fit an efficient extractor fan - and use it.

4. Try painting the ceiling with an anti-fungicidal paint. This will help but is
unlikely to the solve the problem by itself.

5. Have cold showers or baths. This will solve the condensation problem
by itself and save you lots of money.

Good luck,
Frank.

My bathroom window is left open after showering till the room dries out , even in winter there needs to be an exchange of air for the room to dry.... as previous poster says keep the room warm and you shouldn't get the problem...

I second the anti fungicidal paint, then if it does come back you can clean it off with a cloth instead of repainting it.

An extractor fan is probably the only way to cure the problem completely.

There is some good advice on this thread:

I've used the detol mold killer spray and had fairly good results. One day I'll get round to installing an extractor fan...

I cant exactly tell you how to stop it, but I can offer you a little tip to hold it at bay till you either sort out some ventilation or extractor fan.:D

No matter how many coats of emulsion you put on, it will still show through the paint, so, either buy the usual anti-fungul stuff, or get some diluted strong bleach and give it a good clean.
When dry, apply some oilbase undercoat over the mould,(must be oilbased), brush this on the area, and even go a few inches either way.
Do this at least twice, and make sure every part of the area where the mould normally comes through is undercoated.

When completely dry, brush on the undercoat area a couple of times with your normal emulsion, then to get a good finish, roll or paint the whole ceiling again.

This should hold it back for some months, and give you time to sort it out.:D

we had upvc cladding fixed to the ceiling about 5 years ago, never needed to maintain it..

i also have an extract fan, which is efficient enough not to have any condensation on the bathroom cabinet mirror after showering!!

big_mortgage

well thanks (everyone) for that... i usually have the window wide open when showering.. but the window is set low down so doesnt escape a lot. I will try the anti fungal paint first...

i have simaliar problem and have used anti-fungicidal paint! the problem don't go away but it defo helps! its best to use 3/4 coats we still get a tiny bit a damp but you would have to look very closely! when it gets to bad will give it another couple of coats. have not daone it for 3 or 4 years so well worth it!

The first thing you need is a decent extractor fan. Be careful, nearly all of them are far too small. In a bathroom, especially one with a shower you need a fan that can change the air in the room 15 -20 times an hour.

Most fans you see are 4", and they are just not capable of doing that . I have just been through this saga myself, I had a 4" fan above the shower - useless ! When I worked out the figures it was shifting about one third of the air that should have been moved before it shut itself off. Having discovered that, I found that 6" ceiling mounted fans are like the proverbial rocking horse manure. There are window and wall ones around, but I had no power available to do that. I finally managed to find one at Screwfix.

In my last house I had a 6" kitchen type wall extractor; coupled with anti-fungal paint, never had a problem.

we had it bad in our bathroom, i put one coat on the ceiling of blackfriar fungicidal paint from screwfix, painted it in dec and not seen one hint of mould since, and we don't have an extractor, its on the to do list lol

i would link to it but it seems they don't list it on screwfix's site, if you have a screwfix book its on page 191.
