mould + mildew

[b21playa]

got a property and the bathroom has mould/mildew on the walls/ceiling.

Cleaning with a mildew cleaner doesnt remove it all.

It seems to occur due to steam from bath.

what is the best way to remove it, cure it in order for me to paint over it again?

I think when it was last painted, the paint was normal emulsion and not proper bathroom paint

any help appreciated.

EDIT : forgot to mention, when painted before the paint comes away.

Household bleach kills mould. However, I'm wondering if this is an internal bathroom? Baths and showers create steam and if the steam isn't removed by natural ventilation, you need a powerful extractor fan. I believe that in a newbuild, regs now require an extraction rate of around 80 square metres per hour. Also worth remembering is that a warm bathroom can cope with steam better in the short term than a cold one in which steam instantly condenses on every cool surface.

If your budget will run to it, tile all the walls. That will take care of condensation better than any paint.

external bathroom - an extension done about 15yrs ago.

not enough to tile it all, reading around i was thinking of cleaning it all the mildew off, drying it and then painting it with an oil based paint or something with a silk sheen

Mm - I'm no expert but I'd guess this bathroom gets quite cold. A silk finish will still get wet. I've just bought a flat with silk finish walls and they used to run with water after a shower. I installed a super-efficient extractor and it's a lot better. Re cost, bumpy white tiles from Homebase or B & Q are cheap and look good. You might also consider an underfloor heating mat if you're planning on tiling the floor. This will help keep the room at an even temperature, which will help the condensation. Maybe one of the pros will have better ideas. Guys, are you out there?
