Why is the wall of my house against the bathroom moldy

First, use a shovel to remove the moldy position of the wall, and then use 108 glue to brush to the position just now, and then apply putty again, and finally brush it directly with latex paint. If you don't know the steps of construction, you can call a decorator to help, explain these steps again, and the other party will know how to do it.

Second, the bathroom is generally more humid, if you can buy some desiccant to put in it, then the dampness can be greatly improved, and at the same time, the mold situation can be alleviated.

Third, you can spray the moldy area with disinfectant first, and then brush the bleach on it, if your bathroom wall is white, you can use this method. Third, if there is a leak in the bathroom, it is best to check which water pipe is leaking first, and then ask someone to replace the water pipe until it does not leak, and also to prevent water seepage at the location of the wall. However, this situation only applies to the case of mold on the wall due to a leaking water pipe, and if it is caused by other causes of mold on the wall, other methods should be taken.

Fourth, the bathroom should be kept in a good ventilated state, because if there is no ventilation, the mold situation will be more serious, and if possible, an exhaust fan should be installed in the bathroom.

Fifth, you can prepare a bucket of hot water, preferably the kind that boils, then pour half a bottle of vinegar into this bucket of hot water, stir evenly and wet the towel, and then use this towel to start wiping the mold spots on the wall until the mold spots are gone.

It can be said that in order to remove mildew spots in the bathroom, you must use a better method, these methods can be used together, and if one of them does not work, you can also try to use the other. In short, if you don't know what to do if the bathroom wall is moldy, you should honestly start painting the wall.

Generally, the moisture in the bathroom penetrates into the wall, and the back wall is not waterproof and moisture-proof, which is caused by the erosion of the bedroom wall decoration material when the water evaporates.
