How to get rid of mold on the walls with copper sulfate

Copper sulfate is an effective tool to combat the fungus that starts on the walls of rooms. But to get a working solution, you need to know how to dilute copper sulfate for treating walls from mold, and also how to use it correctly. This will help get rid of the harmful fungus.

Mold on the walls

Where does mold come from and why is it necessary to fight it

The emerging mold not only spoils the general appearance of the walls in the rooms, but also negatively affects the health of people who spend a lot of time in them. Mold can cause permanent weakness, headaches, and general malaise. It can cause an allergic reaction, provoke an asthma attack. The constant exposure to secretions of the fungus can lead to various diseases of the upper respiratory tract.

The main reason for the appearance of this fungus is most often increased humidity and inefficient ventilation. Mold spores are almost everywhere. They move freely through the air, settling on objects. When they enter a favorable environment, they germinate and, growing, form a colony, which we observe in the form of dark spots. It is clear that getting rid of this unsolicited “lodger” is desirable as soon as possible.

How to get rid of mold on the walls

One of the most effective and at the same time inexpensive anti-mold agent on the walls is copper sulfate (copper sulfate). It can be purchased in any stores offering goods for the garden, as well as in construction and hardware stores.

This drug is produced in the form of a powder or small granules of blue color. To process the walls from mold, a working solution should be prepared, for which copper sulfate should be diluted in water at the rate of 20-30 grams of the drug per 1 liter. Copper sulfate dissolves better in warm water. Before use, the finished composition must be mixed well. To increase efficiency, you can add a tablespoon of vinegar to the solution.

Blue vitriol in the package

After copper sulfate is prepared, you can begin to process the walls against the fungus.

  • Places where there are traces of mold on the walls should be cleaned. This can be done with a spatula or fine sandpaper.
  • It is advisable to wipe cleaned areas with soap and water. The use of a soap solution increases the efficiency of further processing with copper sulfate.
  • Allow cleaned areas to dry.
  • Using a sprayer or kitchen sponge, apply the solution to the affected areas of the walls.
  • After a few (3-5) hours, after the solution has dried, apply copper sulfate again.
  • This procedure is carried out from 2 to 5 times, depending on the depth of damage to the walls of the fungus.
  • With a deep lesion, the use of the solution on the surface of the walls will not be effective enough. In this case, you must first completely remove the affected plaster and only after that carry out treatment against the fungus.

Application of copper sulfate from mold

We observe safety measures

Copper sulfate is a toxic substance. Although in order to poison them, it takes a long time, much longer than the processing time of the room. However, careless handling can cause serious harm to your body. Therefore, when working with copper sulfate, you should protect yourself.

  • Wear rubber gloves during handling.
  • Protect eyes from accidental splashes with glasses.
  • If there is no special clothing, then you need to dress so that the whole body is closed.
  • Cover your mouth and nose with a respirator or gauze bandage.
  • During processing, open windows, turn on the hood.
  • Clothes, at the end of work, must be washed and dried in the open air.

After processing, you must limit your stay in these rooms to a minimum. After 2-3 days, the solution of copper sulfate will completely dry out, and will not pose any danger to human health.

Mildew Prevention

In order to get rid of mold on the walls forever or at least for a long time, it is necessary to simultaneously eliminate the conditions for its reproduction and development along with processing.

  • It is very important to regularly ventilate the room. Good ventilation is the best protection against fungus.
  • It is impossible to allow overcooling of walls in the room.
  • Try not to allow a prolonged increase in humidity (constantly hung laundry, boiling pans for a long time, etc.).
  • Maintain plumbing and plumbing.
  • Use moisture resistant materials and antiseptic agents for repairs.
  • When installing furniture to external ("street") walls, it is necessary to leave a gap that allows free circulation of air.
  • In rooms with high humidity, it is desirable to limit the number of indoor plants.
  • When replacing wooden windows with plastic, it is advisable to take care of the ventilation system. This is especially important if the walls and ceiling are covered with non-breathing materials: ceramic tiles, plastic or MDF panels or non-woven wallpaper.

If you follow these simple rules, you can permanently get rid of mold.

The appearance of dark spots from the fungus on the walls is very unpleasant, but if the treatment with copper sulfate against it is carried out qualitatively, then the mold will not appear in this room for several years, even under favorable conditions for its development.

      Have you read the article carefully? It also clearly indicated precautions. It is generally undesirable to enter the room after treatment for 2-3 days, until the solution completely dries. And pregnancy makes these conditions even more demanding 😉
      If there is no way to leave the room “without visits”, then it’s better to look at more expensive and safe processing methods. (just my opinion)
      In general, congratulations on the replenishment 🙂

      it is possible, if the walls are not licked, copper sulfate practically does not stink, it can be poisoned if you can get drunk with a “plain text” chemical or breathe the resulting aerosol when spraying from a spray bottle.
