I did not find such a discussion, if there is one, please poke your nose.

Girls, I need your advice. I'm in despair. We've been living in a new house for 6 years, the repair was done right away. And six months ago, the neighbors from below began to complain that we were heating them up, not heating them (when the water was pouring from above), but that we were heating them. After a long search, the reasons found out that water seeps through the seam between the bathroom and the tile, at the junction. They called the master, he picked out the old putty from the seams, made a new one (antibacterial sealant). The neighbors stopped dripping. But now I have a problem, black mold appears on this seam, my bath is thoroughly 2 times a week (with Komet, Sanox, Domestos, which I just haven't tried). After a couple of days, IT starts to grow again! What to do??

Irin, first of all, the bathroom should be dry, so often leave the door open, especially after a shower, and at night, yes, many do not like the sight of an open door, but where mushrooms do not grow dry, the place where mold appears must be treated with household chemicals " anti-mold ", recently bought a Belarusian green bottle (the children started up in the bathroom, processed it, we'll see) and if the remedy does not help, it is necessary to remove the infected sealant and apply a new one.

Irina, we are saved by treatment with a steam generator (we have Karcher).
Kara
I haven't tried it with a steam generator, I'll try, thanks! Nagy, our bathroom door is almost always open. Confused that there was nothing before
Bijou
Hike, the sealant is delicious for mold.

Damp and mold in the bathroom
Now I'm intensively testing the STE tool while I'm happy. The ozonizer kills mold well, but then washed the seam from blackness, first with Domestos and a toothbrush, then "finished off"

Pick out the sealant and re-cover everything with a sealant with additives on which mold does not grow (it is written on them). Treat periodically by any means against mold (although judging by their composition, this is the usual whiteness at an expensive price and with a spray). If anyone has whiteness, take a look at the composition, and I'll see what they write on my anti-mold. By the way, my anti-mildew made the seams on the kitchen tiles as poor as new in 5 minutes ..... Just the usual whiteness, no anti-fats made them white.
The most important prevention (assuming there are no leaks) is good ventilation. Check if you have clogged and no traction.
Agata
Kara, I had a similar story. No means helped, only whiteness helped, and more concentrated. You need to sponge the seams and wait a while, and you don't need to rub hard. She's good at etching blacks, you'll see. On some sites I just pour from a bottle. Yes, and constant airing. The husband also installed forced ventilation by connecting it to the switch. Now I process it once every 2-3 months.
Waist
Ordinary bleach or peroxide (which bleaches the hair, only use gloves to process it).
I treat with diluted bleach CUT OUT How to properly apply bleach, read in the following posts.
It is desirable that the room is not just with the door open, but ventilated. If there is a window, at least open it slightly with the door. Helps.
I wondered why in Ireland there is so little furniture in the houses, everything is as easy as shelling pears ... It turns out to be easier to care for. There is high humidity here, everything must be ventilated and dry as much as possible (within the Irish maximum), otherwise mold will start. Even in wardrobes, clothes can become moldy if not opened for airing / drying.
Mold loves moisture and warmth, so the bathroom is the ideal home for it.

Tried the local specialty - bullshit

"Whiteness" is sodium hypochlorite-NaOCl. It does not possess antifungal and, accordingly, anti-mold activity. A steam generator can really help. And I also advise you to look into a store that sells professional disinfectants used in medical institutions. We have this, for example, Medtekhnika. And ask your consultant exactly what helps with mold. Pro-bac AF, for example. And yes, be sure to dry the bathroom.

Yes, it just bleaches the places where it has turned black from mold, therefore it is treated constantly, in no case should you pour chlorine-containing agents into the sprinklers, if such a need arises, it is better to use a brush or brush for surface treatment
In its gaseous form, chlorine becomes extremely dangerous: spiteful: In order to irritate the mucous membrane, only 0.0001% of this substance in the air is enough.

Upssssss ... Cut out in my post
Nadia, Thank you for the clarification

1. Remove the skirting boards, if any. Completely remove the old sealant under the baseboard and at the junction of the bathtub with the wall.
2. To cut through the place where the grout is between the seams (I forgot what it is called, it looks like a thin drill, such as a drill).
3. Degrease the surface (solvent 646).
4. Solution of copper sulfate - treat the surface for at least a day. Process the adjacent seams on the tile (also vitriol).
5. Degrease the surface (solvent 646). The surface must be DRY from water!
6. Re-seal the joint (with an antifungal waterproof sealant, eg ceresite).
7. Treat all joints on the tiles and the joint over the sealant with a thin joint grout with an anti-fungal effect (I had ceresite). Do not throw away the remains of the mixture, I will write why.
8. After complete drying (several hours) - treatment of the mixture with antifungal liquid with latex (ceresit). It is invisible on the tiles, but it is not washed off.
9. Install a UV lamp (medical equipment) in the bathroom, turn it on for 1 hour a day when there is no one there.
10. Forced ventilation in the bathroom.
11. Heater or warm floor, especially when the heating is turned off.
12. Renovation of the ventilation shaft (check, THIS also likes to live there).

The rest of the grout mixture for thin joints will come in handy. If mold growth is noticed, treat it with cotton wool with hydrogen peroxide, removing blackness, dry it, degrease it, grout it locally, treat it with a fungicide with latex (it closes the micropores on the grout).

Separately buy a latex-free liquid fungicide (it can be sprayed once a week in places where light does not penetrate, UFO).

In general, in the new apartment we brought IT out. I wrote for a long time, in fact for a couple of days of trouble and then follow. For two years, only once a small speck appeared under the bathroom, they immediately took action.

The steam mop is a thing! And a steam cleaner with a thin spout. Bridge is talking.

AND WORK IN A MASK !!!

PS In general, it is strange that it was flowing to the neighbors, which means that you have something wrong with waterproofing there.

So it is not necessary to close the seam between the tiles, but to eliminate the cause.
Water flowed from somewhere, which means there is a leak in the pipes, rather drainage.
In addition, submit a request to your management company to check the ventilation, they must do this free of charge.

Ozone also burns your tissues, especially in your lungs.

I have the same problem while the dehumidifier is working, everything seems to be fine, but if you turn it off for a day or two, the mold appears instantly.
Byaka zakalyaka
It can appear instantly only where it is not completely eliminated, but only superficially washed off. And mold needs moisture, heat and time

These lamps do well:

If the mold has started, 30 minutes-1 hour a day, then ventilate well (such lamps do not give much ozone, but there is a little smell), 15-20 minutes is enough for prevention. once a week.
In general, it is good both in the kitchen and in the apartment, especially if there are small children and during the period of acute respiratory infections.
Naturally, there should be no people or animals at this time. It is better to cover the flowers (I do not close my own during processing ~ 15 minutes), you can not worry about the aquarium.
Only lamps should be UV-C with a wavelength of 254nm. UV-A and UV-B are softer and do not affect viruses, microbes and fungi.
mur_myau
Amasar,
I have a UFO lamp from medical equipment above the door to the bath. Once a day "quartz" room.
Thank you for the note about the wavelength, I'll go and read what is written in the device's passport.

Only it is dangerous with them, and until the issue of humidity is resolved, they are more harmful, because even turning off you get air poisoned with ozone, nitrogen oxides and other thousands of nasty things.
Mold itself basically burns ozone.

No, unlike many domestic lamps, such lamps do not produce ozone. If interesting from the technical point of view, then for the formation of ozone, a wavelength of about 185nm and quartz glass are needed. And here the balloon is made of uviol glass, which does not pass this part of the spectrum ( 🔗).
The bactericidal effect is determined precisely by radiation in the region of 254 nm, it disrupts the protein membranes of microorganisms and "spoils" the DNA of cells. Radiation does not particularly affect fabrics, plastics and paints. For at least several years, I have not seen any changes.

P.S. Actually, we are talking about these lamps: 🔗

ABOUT! How many hours of operation are allowed? As far as I know, the spectrum of all UV lamps degrades over time?

ps. Just fresh impressions - plastic pipes are laid in the garden instead of hoses. Yesterday they found that in those places where the sun hits them, the plastic collapses. ((

mur_myau, what exactly? It is something like a mobile air conditioner that precipitates water dissolved in the air. Buzzing, blowing, collecting water in a container ...
Chamomile
The topic is interesting, I subscribe.
Amasar
BijouThe spectrum does not degrade, it is determined by glass. Power degrades, my lamps have an operating time of 8 thousand. hour, while the radiation power drops by 20-30%. For home use, this is more than enough, because.the lamp works a maximum of 20 hours per month.

Hmm ... I heard such a fable that it is harmful to go to inexpensive tanning salons precisely because the lamps are not replaced regularly - it is expensive. Shines and okay. And the spectrum changes and begins to severely harm the skin. Wrong?

I heard it too, but I don't think it's true. But what is rarely changed - I believe
Specially raised specifications for Philips UV-A (for tanning) and UV-C (germicidal) lamps. Operating time of lamps for solarium 500-900 hours, bactericidal 9000-18000 hours. From TB only that which cannot be broken, since there is a small amount of mercury in the flask and is not located next to bactericidal (burns of the skin and eyes). About lamps for tanning beds only this:
"Over time, the emissivity of the UV lamps gradually decreases, which leads to a decrease in the efficiency of the device. To compensate for the aging of the lamps, you can slightly increase the duration of the sessions or replace the UV lamps."

Bijou, I specifically looked at Philips, because as a manufacturer, frequent replacement of lamps is beneficial to him and liability is not profitable (they even write in the instructions for the washing machine that they are not intended for cleaning pets), if there was such a thing, it would definitely be present there ..
And replacing lamps in a solarium should really cost a pretty penny, it turns out that you need to change every 10-20 days from a dozen large lamps, each 1-1.5 tons. R....
Bijou
AmasarSo far, I have only come across the words that in those lamps where the spectrum is determined by a phosphor, when it burns out, the spectrum may shift to a harder side. Sleepy I think badly and how much this can be true I don't really understand.))
But in advance it became scary to use energy saving.
Irlarsen
Not so long ago I faced the same problem. We decided to install a warm floor and forced ventilation. The ventilation turns on if you turn on the light and turns off after you turn it off after a few minutes. Very comfortably
Well, it is clear that the ventilation shaft itself was checked and processed (not we, we called the service)
mur_myau
Irlarsen,
And we had an anecdote from the series "You can't imagine it on purpose."

We drove in and started checking the ventilation. There is no draft in the bathroom. The ventilators were called and they took out three bricks from the mine. The thrust appeared! But the smell of mold, and there and in the bathroom, THIS began to grow.
I had to take action. (I wrote above, etched at the joints of the tiles and in the mine itself).

"Do not wake up dashingly while sleeping quietly."
Medtech
mur_myau, you still have not figured out the ventilation in the bathroom? Does fungus and mold still grow?
mur_myau
Medtech,
Etched with copper sulfate. I wrote the rest above on the first page.
