Does anyone know of a supplier of anti-fungal paint?

The problem: a solid concrete (or other masonry finish) ceiling, the
shower steam goes straight up and condenses, with the inevitable result.

I'll be adding forced ventilation for the new occupants. However I would
like to know what paints are available which are truly anti-fungal?

I used this two years ago. No problems since. It is expensive though.
Also, install an extraction fan - the centrifugal type. Not the axial fans,
they are crap.

I wonder why people pay premium prices for antifungal paints when they
can just add antifungal compounds to whatever paint they wish.

The cheapest is crushed aspirin tablets. Copper compounds are
antifungal, and a longer lasting choice if something of low solubility
is picked.

Copper compounds are blue. My ceiling is white! :-)

What do you do? Just stir in some copper sulphate?

Brilliant white is mildly blue tinted white rather than pure white, but
the amount of copper needed is low enough not to be noticeable. Copper
compounds come in blue, reddish, black, etc.

I'd use a less water soluble copper compund myself. Last time I did
this I used aspirin, but lower solubility is better, lasts much longer.
I worked out how many I'd need to get the concentration required to be
effective, powdered them, and mixed in.

If I were doing it today I'd probably just add copper filings, easier
and longer lasting.

Look at anti-fungal treatmnts containing quaternary ammonium compounds.
They are available (sorry, don't know a brand) as sprays or solutions
to kill existing mould growth

Surely this is the answer - or use a slab of expanded polystryene to
insulate the ceiling. I would have thought it far more preferable to
eliminate the condensation than to attacked the problem chemically. If
nothing else the insualation will last for ever while anytning 'anti-'
will deteriorate with time.

Having said that - is the aspirin thing true or are you pulling the
collective leg ?

OK I could afford to loose a cm or two (but not much more) from the room
height and use celotex or similar. But it would likely need to be skimmed
over (under really?) to look OK.

Polystyrene tiles are just too naff
even for a middle market 1 bed flat.

Could try polystyrene 'lining paper' but that's only a few mm thick and
might not work well enough.

And I think unacceptable on fire safety grounds.

The problem really is not condensation per se, but condensation wetting a
surface and providing the conditions for mould to grow. If you can replace
the surface with something which sheds condensation, mould will be a lot
less likely to grow. Tiles would work, or the tile or marble style plastic
laminates used in commercial kitchens or bathrooms. The condensation should
simply run off harmlessly, and if some mould does grow then the surface is
wipe-clean with bleach.

I've used it on a cold wall in a bathroom and it worked quite well(in
that it moved the condensation elsewhere until proper ventilation was
sorted out). Even where water does condense on it it seems to
evaporate somewhat faster so minimising the opportunity of mould
developing.

I can see no problem with them on a solid concrete bathroom ceiling.
By the time they ignited anyone in the flat would long ago have
ceased worrying about it.

Suspended polystyrene ceilings are a different kettle of fish.

I think I'll basically clean off the existing with bleach.
Add an extractor fan. Which will mean a Part-P building notice wink.
And paint with an anti-mould paint.

The tenants before the last lot did not have a problem so the users also
have a big part to play in the matters.

Flat is in a block with communal (unvented) HW the shower is truly superb
off a 'contract' grade manual mixer. This probably encourages luxuriating
under the warm fire hose...

nod But you've got a receipt for an extractor fan you bought last year -
proof you started the job before 31st Dec.

copper lasts many decades - water soluble aspirin wont though.

Sure, aspirin turns into salicylic acid, which kills fungi. I was about
to put brush to wall one time and I thought, hold on, it would only
take a few mins to put something antifungal in here, and thats what I
had to hand. It worked. Safe, effective, very easy, dead cheap, but
probably not long lasting.

I always keep 4" bathroom timer fans in stock - it'll be old stock.

IME a 'fungicidal wash' such as the Dulux one here

http://www.duluxtrade.co.uk/webapp/w...ctType=dulu x

makes a very effective pre-treatment. Provided the new ventilation is
effective there's surely no reason not to follow up with ordinary
emulsion - or an alkyd-based eggshell finish if you're still worried
about damp.
