What to do if your walls are moldy Tips for dealing with moldy walls

What should I do if my walls are moldy?

1. When there is already mildew on the wall, we can first use the simplest way to solve it, we have toothbrushes at home, or other brushes, these brushes can temporarily clean up the mold on the wall. If you want to stop the mold from growing, you can also use a dry toothbrush to clean the mold and then use a soft cloth with alcohol. In this way, the walls will become drier and mold will not be able to grow.

2. Bleach, diluted with bleaching powder and an appropriate amount of water, can be used to solve the problem of mildew spots on the wall after being put into a spray water bottle. If you don't want the bleaching powder to get on your hands, you can also wipe it with a cloth. Once the wall is not damp, it will generally not grow mildew if it is kept dry.

3. Alcohol, if the mold on the walls of our home is not very serious, then we can also use alcohol to paint the walls. Dilute alcohol and water and brush the walls to remove most of the mold. However, when we use alcohol, we must pay special attention and never let a large amount of alcohol get on ourselves.

If you have masks, glasses, and gloves at home, you should be equipped with them. And after applying alcohol to the walls, pay attention to ventilation as well. Let the smell of alcohol dissipate quickly.

1. First clean the wall and expand 30-50cm outward along the outermost edge of the wall mold.

2. Use a shovel blade to shovel the skin layer of mold growth to the cement mortar plastering layer.

3. If mold appears on the blank wall, just use a wire brush to brush off the mold.

4. After the above treatment, evenly brush the anti-mildew isolation solution (bottle A) 2-3 times with a brush or roller brush.

5. Brush horizontally, vertically, and horizontally again to ensure that the bottom liquid is fully brushed and evenly brushed, and each time needs to be thoroughly dried before the next brush.

6. After the anti-mildew isolation solution is fully dried, stir the anti-mildew isolation layer (bag B) with water to the paste, and scrape the removed wall in batches, and scrape it until it is level with the uneradicated plane.

Wall mold not only affects the appearance, but also has an impact on the health of the people who live there, so if the wall of the home is moldy, it must be dealt with in time, let's take a look at the causes of wall mold and solutions.

Causes of mold on the walls.

1. The construction quality and craftsmanship are poor, resulting in gaps between the doors and windows and the wall during installation, and the plastering is not full during the wall masonry, forming a cold (hot) bridge.

2. The insulation of the exterior wall itself is not done well, resulting in the cold of the wall, resulting in the cold of the wall, and the indoor water vapor will crystallize into water droplets on the wall, and the wall will become moldy and hairy when it is wet.

3. The wall waterproofing is not done well or there are leakage points in the pipeline, resulting in damp and long hairs.

4. In the process of using the house, do not pay attention to ventilation, resulting in excessive indoor humidity, and the damp wall is easy to adhere to the floating matter containing nutrients in the indoor air and generate mold.

5. Decoration is carried out before the wall is dry, and the moisture is enclosed in the wall, which will also lead to moldy and hairy walls.

6. The use of inferior interior decoration materials is easy to produce mold under a certain temperature and humidity.

What to do if the walls are moldy.

1.When the mold on the wall is not severe, it can be wiped with a damp cloth or washed with water, or if it cannot be completely removed, it can also be cleaned with bleach to remove the mold.

2.If you can't clean the mold on the wall with clean water, it's best to scrape off the mold on the wall and brush it again.

3.What should be done to prevent the wall from recurring in the future? It is recommended that you still brush a layer of waterproof paint, latex paint, etc. on the wall, so that you can do it once and for all, and then you don't have to worry about this problem in the future!

4.Finally, it is recommended that in order to prevent mold on the wall, it is best to recommend that you always ventilate the room and maintain a clean and tidy environment, so that the indoor wall will not be moldy, and there is no need to worry about it.

How to prevent mold on the walls.

1. Always open the window for ventilation, or turn on the fan to keep the indoor air circulation.

2. Purchase indoor desiccant for indoor use, which can effectively remove indoor moisture. After the active ingredient of the desiccant is used up, it needs to be replaced in time.

3. The best way to prevent mold on the wall is to prevent condensation on the wall. In northern regions, when the room temperature is 18 degrees Celsius and the relative humidity is 60 degrees, anything below 10 degrees Celsius will condense.

There are three reasons for the condensation of the wall: design, construction, and use. The reasons for the design are: although the wall meets the moisturizing requirements, the beams, slabs and columns are not moisturized; The heating technical measures are not in place, and the radiators are not properly arranged; The convex corners and special-shaped columns on the windward side of the exterior wall do not have a thickened moisturizing layer, resulting in the thermal insulation effect not meeting the standard.

The reasons for the construction are: the insulation material does not reach the thickness specified in the design; strong cracking, ventilation; The joints between doors, windows and walls are not properly moisturized and sealed.
