The wall is broken, how to repair it?

If it is only a small piece, just scrape it with paint or putty. If the damaged area is relatively large, it is necessary to remove all the debris and then carry out repair work, and pay attention to it when repairing. Note: 1. If the house is often unoccupied, the walls will be moldy, and then the walls will break. Therefore, we must open the doors and windows regularly, and it is best to expose the clothes and bedding inside to the sun to prevent mold from breeding. If mildew has occurred, it should be removed in time. You can remove the mold with a shovel and then repair it with spray paint. If the wet place is a big wall, then you must shovel off all the walls with a shovel, then clean them up and repair them with putty or paint. Be sure to choose some high-quality paint and putty powder when maintaining. 2. If the kitchen and bathroom will be moldy because of humidity, you can buy some green plants and put them in the bathroom and kitchen. If possible, you can buy an air purifier to purify the internal air. 3. Be sure to do waterproof work when decorating. You can buy some waterproof paint to smear, which can prevent the damage of internal moisture to the wall.
