Nowadays, young people basically work in the city, but the old houses at home are empty. When I go home for the New Year, I usually go back to my hometown, but what if the house is moldy? We use desiccant and activated carbon to prevent moisture and absorb moisture. Use a small bag of lime, tie it into a small bag and put it in every corner of the room. Buy an air dehumidifier, which is like a vacuum cleaner, collecting moist air together. Usually, more windows should be opened for ventilation to reduce the indoor steam content.

When the mold is on the wall, you can first brush the mold stains with a dry toothbrush, and then gently wipe them with a soft cloth to prevent mold breeding. In addition, the mixture of bleach and water is mixed according to the ratio of 1:99, poured into a spray bottle and sprayed on the moldy wall. Sand the wall with sandpaper, then brush a layer of waterproof primer, and finally brush latex paint.

The problem of moldy walls can be solved by adding water and bleaching agent to make water according to the ratio of 1:99, pouring it into a spray bottle and spraying it on moldy walls. If the weather is still wet, bleach and water can be applied to the mold on the wall at the ratio of 65,438+0: 20 until the wall is dry, then the wall is polished smooth with sandpaper, then waterproof primer is applied, and finally a layer of latex paint is applied.

Clean the moldy parts of the wall (the larger the cleaning area, the better the repair effect); Brush thick latex paint and new batch of gray thick paint (alkyd paint). Because the mold on the wall is caused by humidity, we should pay more attention to ventilation during use. Although the old house looks ugly, it is warm in winter and cool in summer. It's still good to raise it. It feels like a villa.
