a bathroom ceiling. It's small, only two years old, well ventilated (extractor and window) but we can't stop one corner going mouldy. We've done it in good quality silk emulsion, but within a few months it's back. Zinsser?

Perma white is pretty good in these situations, it's quite thin though so hopefully you are painting in the same colour.

Should be fine then, a couple of coats covers pretty well as long as the staining it bleached and cleaned first.

I see people touting it as great as a general purpose paint, it isn't, it's expensive and way too thin, for most jobs you would need double the coats or more compared to a good quality vinyl emulsion or eggshell. As a final top cost/2 coats though on a surfaces likely to suffer it does work very well.

I have the same problem with their all coat exterior, it's superb paint, it sticks well, looks great even years later, is easy to wash and resists mildew etc. But it's very thin and takes quite a few coats if you don't already have a surface in a similar colour.

Phil, - I've used the ronseal anti mould emulsion for a couple of small bathrooms and not had and mould issues. But mind you, didn't have any to start with!

I agree with Zinsser permawhite being thin.

Personally I'd just go and get a top quality trade white emulsion from the paint specialist anything of crown/leyland/ dulux etc.

That won't help, if he is getting mould now he needs something with a fungicide in it. I only use high quality paints and have still had issues, just had to repaint a wall this year for that reason.

Hi

IMH, clean the growth off with fungicidal fluid then paint with a paint for Kitchens and Bathrooms. It has more resistance to moisture. Ive used it in my small poorly ventilated shower and no signs of mold.

Paint designed for bathrooms almost always has a fungicide in it, kitchen paint sometimes as well. They are marketing gimmicks really, they are rebadged vinyl silks with fungicides added, which is exactly what Perma white and other mould resistant paints are.

I was always told that any areas that had mould needed sealing with an oil based paint as once the mould was there it would just return once it got damp again.

I would clean off the mould using some kind of anti mould cleaner/spray then coat the area with some oil/spirit based undercoat then some decent emulsion over the top.

That doesn't work either, tried that.

Move house? It's no help, but I can't think of anything other than diversions already made. Is it a colder corner? We have one, that always peels first, condensation gathers there, etc :cry:

I am just saying that Doug's solution doesn't work, the solutions I mentioned before work fine, also it's Phil's problem here lol

I found fitting a heat recovery ventilator that runs constantly at a trickle did help reduce bathroom mould a fair bit (and my bank balance quite a lot !). The downsides of the one I got is that that it uses a humidistat, and makes a racket. You can't manually reduce it back to a trickle when it is on boost, so if you're fed up of the noise, you have to turn it off. I'd buy the one with manual boost next time.

I used eggshell paint on the ceiling, the mould there is is mostly superficial on dirt / dust, not the paint itself so wipes off.
