Mouldy Bathroom

[faithhealer]

Large bathroom, half original 70s, half extension (dont know age) extractor fans both sides including one over the shower. Mould all over even on tiling that was redone a year ago. Swears he used top silicon. Going to strip it including all the plaster, redo (I'm guessing there will be an additive for the plaster, will tank etc and epoxy grout. Anything else I can do to stop mould? Any thoughts lads?

get them to wipe the condensation of the tiles in winter,we all know how hard it is to leave a window open when it's -15c outside

If there is mould in the plaster it will transfer through the grout etc..

Good quality extractor unit and good regular cleaning regime will keep it right..

That's a good bit of wisdom to know...

I dry my shower walls in my small bathroom with a microfibre cloth after every use, it's very quick and effective, and if in a rush I spray shower clean spray on before I leave, that could be a good tip for your customer? I think the microfibre cloth is more effective than a squeedgy on the grout...

sounds like cold bridging to me if they have two extractors and still suffering from condensation

mould anywhere else in house at all? i installed something called envirovent in my hall a year ago,,we had a mould issue as there wasnt enough ventilation in the house as a whole and it was all gathering in the bedroom and bathroom,sounds dodgy if they have 2 extractors and it hasnt solved it

Yes, but it does depend on them using them, too... and if it's a badly insulated north wall..

condensation is a tricky one, sometimes its a simple solution like leaving a window open and other times it can be a nightmare to pinpoint the cause and cure it

sounds a good systen you have Kilty

If you use mould and mildew remover which is available at most major supermarkets. We spray it over the bathroom once a month and any discolouration or scum just rinses off after ten minutes. Great for ceramics and glass. One of these little known secrets.

Plain pool chlorine mixed with water at 1;5 is the cheapest and most effective way to clean mould.
Spray it with a spay bottle and let it do its job.Rinse with water
treat every 2 weeks
mould is a side effect of not cleaning your bathroom.

That's heavy that is heavytrevy! Sometimes mould can just be a pain in the back side and always comes back no matter how much you clean. I'd also suspect it's in the plaster and working it's way through to the tile. I guess there's quite a bit too. Once it's there, without taking of the tiles and treating the plaster it'll just keep coming back.

Got a sister-in-law with a two bed terrace, single brick walls, has to decorate annually (bless her). It's a problem with the whole area where she lives as all the houses were built back in the day with single brick external walls and it just attracts damp even on the hottest days.

Have you checked the plumbing for leaks? Is there water coming in from outside? Does the bathroom smell like the London Dungeon's? Have you used a moisture meter on the walls? Does the mould like a particular part of the room? These are just a few thoughts off the top of my head......and now for the silly thought.......would UFH be of any help in this situation? i.e. it would help to dry out the room quicker after a shower. I know that thought contradicts the fact that mould likes warm, dark, moist places. Good luck.
