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?

heavy but true, mould has to have something to eat for it to grow, heres a little snippet from wiki,
There are thousands of known species of molds which include opportunistic pathogens, saprotrophs, aquatic species, and thermophiles.[2] Like all fungi, molds derive energy not through photosynthesis but from the organic matter in which they live. Typically, molds secrete hydrolytic enzymes, mainly from the hyphal tips. These enzymes degrade complex biopolymers such as starch, cellulose and lignin into simpler substances which can be absorbed by the hyphae. In this way, molds play a major role in causing decomposition of organic material, enabling the recycling of nutrients throughout ecosystems

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.
