Moldy walls are a headache for all residents. If small patches of mildew are fine, it may just be caused by excessive humidity in the room. If large areas of mildew may require complex renovation treatment, then what are the causes of moldy walls? What about mouldy walls? Let’s have a look!
What are the causes of moldy walls
Wall mildew is caused by wall dampness, and there are generally three reasons for wall dampness.
1, water supply, drainage pipe or heating pipe leakage, resulting in moisture on the wall, a long time, the wall will be moldy.
2. External rain seeps into the room, resulting in damp walls. A crack in the baffle under the balcony window (mostly made of prefabricated floor slabs, so it is prone to cracks where it meets the wall) or a poor sealing of the window can cause outside rain to seep into the interior.
3. Wall insulation is not done well, resulting in a large temperature difference between indoor and outdoor, so that the water in the indoor air will condense to the wall when it is cold, resulting in wall humidity.
What if the walls of the house are moldy
(1) Dry toothbrush to brush away mold
When there is mold on the wall, you can brush off the mold stain with a dry toothbrush first, and then rub it gently with a soft cloth stained with alcohol, so that you can make the wall dry and prevent the breeding of mold.
(2) Use bleach powder to solve room mildew
The problem of moldy walls can be solved by mixing bleach powder with water at a ratio of 1:99 to make water agent, which can be poured into a spray bottle and sprayed on moldy walls. If it is still in wet weather, you can use bleach and water at the ratio of 1:20, wipe on the mold wall, when the wall is dry, use sandpaper to smooth the wall, and then brush a layer of waterproof primer, and finally brush a layer of latex paint.
What to do if the room is damp
1, the use of dehumidifier. Room damp, can use desiccant, activated carbon, moisture-proof, moisture absorption. Can use desiccant, activated carbon. Supermarkets have a lot of desiccant dedicated to moisture-proof dehumidification, the most common is the two types of moisture box and dehumidification package.
2, Buy an air humidifier, it is like a vacuum cleaner, can concentrate the wet air together, wait until the moisture a lot of time will turn into water. Use air conditioning to dehumidify. Family air conditioning generally has the function of dehumidification, however, air conditioning to adjust the indoor air humidity way is slower, generally takes two or three hours, and will make the indoor people feel cold.
3. Dehumidification with lime and bamboo charcoal. With a small cloth bag with appropriate amount of lime, tied into a small bag placed in each corner of the room, lime itself has the effect of absorbing moisture, can also slow down the indoor humid condition, at the same time, lime and disinfection effect, kill two birds with one stone. Bamboo charcoal dehumidification, can be used repeatedly, but to use more, less effect is not good.
The above is the relevant introduction of the house wall mold, I hope to help you.
