If a fungus is found on the walls in the room, then it must be dealt with immediately.

Classification of fungi

Most often in Everyday life man faces the following types fungi:

Molds grow on concrete, stone painted surfaces. They manifest themselves in areas colored black, brown, blue or green color... Such mold can completely destroy the materials used in construction and decoration;
Blue fungi attack wood material. The walls turn gray-blue. Penetrating through the varnished surface, they allow water to flow in and mold to germinate. Among tree species pine is especially unstable to the effects of the blue fungus;
Rotting fungi mainly damage wood materials... Rotting fungi are bacterial, brown and white. When infected with bacterial rot, the tree collapses from the inside, the wall turns dark gray, and the strength of the wood decreases. If the wall is damaged by white rot, the cellulose is completely destroyed. Even thick ones in 1 month Oak planks may become unusable. Brown rot spores lead to wood splitting.

" my regards!
Even in my youth, I lived in an apartment on the fifth floor and in our kitchen in the corner outer wall mold appeared at home after we started drying baby diapers in winter time of the year.
This means that the first reason for the appearance of fungus on the walls is the increased humidity of the room, which does not disappear for a long time.
The second reason is poor ventilation of the room, i.e. lack of proper ventilation.
But then we did not know this because of our youth.
On the advice of our parents, we made a solution of copper sulfate with lime and treated the damaged parts of the walls.
This gave its results, but not for long. After what time the fungus reappeared.
I think that many owners of apartments and houses are faced with the problem of this very unpleasant phenomenon, which is sometimes not easy to cope with.
In order to help understand this issue, I decided to write this article.

Causes of mold and mildew on the walls

High room humidity (above 60%).
Thin walls that freeze through in cold weather.
There is no heating or there is heating, but not enough.
Note.
I described how to calculate the number of radiators per room in the article "".
Not high quality (not correct) brickwork exterior walls or poor-quality joining reinforced concrete slabs among themselves, as well as not insulated window slopes, which affects the penetration of cold air from the street.
Note.
I told how to insulate the slopes in this one.
Plastic windows characterized by high density, can only aggravate the problems associated with poor air exchange and the creation of an unfavorable microclimate in the room.
Not adequate ventilation or the complete absence of it.
In private houses, this is also a poor waterproofing of the foundation.

How to get rid of the fungus on the walls, how to remove and remove it

To do this, we perform the following work:
✓ We remove the wallpaper, if any.
✓ Determine the depth of the lesion.

note that the fungus can easily penetrate through the plaster to a brick or concrete wall in a year.

✓ Therefore, it is possible and necessary to remove the plaster layer from the wall.
✓ We remove.
✓Clean off the plaque thoroughly.
You can use a metal brush for this. If there is no such brush, then a large sandpaper or with a scraper.
Important!
✓First, moisten the wall surfaces with water.
Water prevents fungal spores from spreading through the air throughout the room during cleaning.
✓ We clean everything under the broom.
✓Dry the walls with a fan heater or industrial hair dryer.
✓ We treat the cleaned surface with chemistry.

List of drugs against fungus and mold

Which, in my opinion, do a good job with the task at hand.

1. Alpa Fongifluid fungicide - a solution for the destruction of moss, fungus, lichen, mold (0.5-25l).
It is good because it can handle almost all surfaces:
concrete blocks, cement plaster, gypsum plasterboards, wood and its derivatives, stone, brick, roof tiles, ceramic tiles.
This preparation has no smell and no chlorine! By the way, I described how to process wood in the article "".

2. Dali - antiseptic against mold and mildew (0.6-5l).

The specs are the same, but it's cheaper.

3. OLYMPUS Stop - mold - composition for the destruction of mold (5L)
The characteristics are the same, but it is good for rooms with high humidity.
For example, a bathroom or a cellar, a basement or a greenhouse.
It can also be used for the treatment of facades, plinths and roofs of buildings.
4. Biotol - spray - agent against mold, mosses, lichens and algae (0.5 l).
Used in kitchens, laundries, walled balconies and even memorials, fences and tombstones.

Of course, the list goes on and on, but these are the tools that I had to use in my work.
I give preference to solutions that do not need to be poured anywhere, so as not to come into contact with chemistry once again, no matter how toxic it would not be!
For example, a liquid that is already packaged in a spray bottle. Spray yourself, that's all.

Let's continue.
The key to effective removal fungus and mold is to eliminate the cause of their occurrence, which I mentioned above. Only after their elimination should one proceed to the final stage, the removal harmful microorganisms and any traces of their manifestation.

Treatment of the wall with a special agent against fungus

For this purpose, you can use a regular brush, roller or spray.
I sprayed it with a spray can.
But not in all cases it is suitable, because the spray volume is quite small (0.5 l). Therefore, it is only good for small areas.
Advice.
It is better to apply two or three coats, with the next coat being applied after the previous one has dried.

note that when working with drugs, in no case should you neglect, i.e. work without special means protection!
! In order to avoid even accidental contact with hazardous substances, work should be carried out with a mask, protective gloves and remember that the room is well ventilated. From the time of completion of the work and the beginning of the use of the premises, at least 24 hours!
If there is furniture nearby or houseplants, then they need to be covered or taken out!
After all this, you can start applying plaster to the walls.
Advice.
It is better to plaster with a mixture with such a description.
"Plaster plaster mix designed for high-quality plastering of walls and ceilings in rooms with normal humidity.
Unlike cement plasters, the mixture does not require additional filling. Contains in its composition, which prevents the formation of mold and fungi, has increased crack resistance. "
For example, ALEST.
Also, wallpaper glue should contain an antiseptic.
In short, we are fighting mold on all fronts.

Another example of removing the fungus

Very often in the bathroom, the contact of the bathtub or washbasin with the wall is covered with ordinary silicone (sealant).

Over time, a black coating (fungus) appears in this place.
To get rid of it, you need to do the following:

Remove, i.e. scrape off the silicone affected by the fungus.
Treat with fungicide.
Apply a new layer of sealant, but already containing an antiseptic.

For example, Domosil Micro silicone antifungal sealant (0.280 ml).

note , if the seams between the tiles are covered with fungus, then you need to clean them with a special scraper and wipe them again with a grout, which also includes antiseptics.

That's all there is to measures to remove mold and mildew on the walls. It remains only to focus on an integrated approach, since the removal of the fungus can be effective only if the causes of its occurrence are eliminated. Cosmetic removal of it from the surface will save you from the fungus for a short time. Which can lead to more serious consequences when the fungus penetrates into the depths of the walls, and from there it will be almost impossible to remove it, and over time it will destroy the entire wall.
So, in order to guarantee there is no relapse, it is necessary to additionally insulate the walls with thermo wallpaper... But I'll talk about this in the next article. Therefore, subscribe to the news.

It is no secret to anyone how deplorably the fungus affects human immunity, causing various disorders of human life, primarily related to the work of the brain, respiratory tract, and stomach. Diseases become chronic and curable only when you change your home. So what is it to change housing every time if black spots are found on the wall?

The reasons for the appearance of the fungus are different, but first of all, this is a problem with air and water, which, getting into the appropriate environment, begin to "produce bacteria" (spores). High humidity and lack of ventilation are often the first echoes of mold. It can also be affected by room humidifiers that are used for plants. And to be honest, very few materials are not exposed to mold at all, so it can often be found in the bathroom, toilet, near windows and air conditioners. In addition, in books, wallpaper and even the refrigerator.

How do you know if there is fungus in the room if no stains were found? You will smell: the smell of heavy dampness, extremely pungent and unpleasant. Then inspect the integrity of the wallpaper, and if you see a place that has deformed and changed color, most likely a fungus has formed on the wall.

Please note that mold does not appear, the treated room must be constantly ventilated, otherwise you cannot avoid reappearance.

Believe me, even if you wash and scrub the mold, without adequate ventilation, it will reappear.

The easiest steps to remove mold on the walls

And so we provide a set simple solutions to remove mold that has formed in your home:

Cleaning and washing. It is necessary to thoroughly wash the floor, walls, ceiling from mold.
Means. Use a special fungus cleaner. You can buy at a hardware store - there are a lot of them today, different manufacturers and using different active ingredients.
Remove, throw away, burn things that have been damaged by mold, since you cannot clean them (the mycelium, located deep in the material, is almost impossible to remove), and you can ruin your health using them.
Ventilation. Make sure that the room is provided with good ventilation so that the air is constantly renewed.
Decrease in humidity. Since moisture is one of the causes of mold, reduce it to a lesser extent. Use a fan and open windows in sunny weather for the sun to dry the room. Use household dehumidifiers air and humidity control systems. By the way, good air conditioners do a good job with this function.

How to remove fungus from the wall

When the mold has already appeared, but it was not possible to prevent it, you should familiarize yourself with the next possible solutions this problem. For this, in addition to cleaning, you should use chemical and not only agents. It is especially important to work with these funds in protective gloves and a mask, since fungal poisoning can lead to the most dire consequences. Also read the instructions for use available. In addition, it is worth considering that wallpaper, furniture are also affected by mold and it is not possible to clean them from it at all.

How to remove fungus with an antiseptic

An antiseptic is considered to be the most effective against mold. You can buy at any hardware and hardware store. An antiseptic primer can get rid of mold and resist its appearance in the future.

For application you should:

Clean the surface. Wipe off the damaged plaster down to the bricks, if necessary (the plaster destroyed by the mycelium is loose, crumbles).
The primer can only be applied to dry surfaces.
Once the primer is dry, you can paint, putty or wallpaper.

Removing fungus with bleach

Hard to imagine, regular store-bought bleach also serves as a mold-killing agent. In addition, it is not very toxic, unlike the primer. This product removes any mold in the house, because it contains chlorine, which kills spores. Therefore, it is often used for bathroom, tile, flooring, etc.

But there is one thing, the product strongly corrodes the skin, so it can only be used with protective gloves. And also provide good ventilation in the room. Surface treatment should be carried out in a ratio of 1 to 10.

How to remove fungus with vinegar

Another simple and affordable way to kill fungal spores is vinegar. Its seemingly weak acid is capable of killing most types of fungal spores. In addition, it is not as harmful as the fumes of the bleach.

Vinegar should be applied using a spray bottle and a sponge. To achieve the final effect, vinegar should be applied once a week to problem area and wash away the remains of the fungus.

Below is a video on how you can get rid of the fungus on the walls. The author shows his way of dealing with the problem. Maybe it will suit you too.

Remove mold from walls with hydrogen peroxide

An even more affordable remedy is hydrogen peroxide, because it has antiseptic, antifungal qualities. You can buy a 3% -5% peroxide solution at any pharmacy and see it in action. It is non-toxic and also does not have a nasty smell. It can remove mold from any surface and, in addition, can whiten fungal stains on the walls.It is especially worth using it to clean mold and colored fabrics from mold, since hydrogen peroxide can corrode the color to the point that you just need to throw the thing away.
