To make the wallpaper moisture-proof, it is necessary to grab the decoration from the decoration, and lay a good foundation to effectively avoid many troubles in the future.
The first step is the preferred breathable material. There are many kinds of wallpapers on the market, such as non-woven fabric, wood fiber, PVC (polyvinyl chloride), glass fiber substrate, cloth surface, etc., relatively, PVC wallpaper. The most airtight, it is most easy to smother the water vapor discharged from the wall. It will be easy to form mildew after a long time.
The second step is to keep the dry wall surface of the wall dry and the new cement construction must be maintained for 20 days to 40 days before the wallpaper can be laid. It is worth noting that when decorating, be careful not to let the non-standard construction mix the sea sand that is not suitable for the wall flour brush. Before you post the wallpaper, you need to handle the base. If the second-hand house is refurbished, the gap in the wall must be filled, otherwise the wallpaper will be easy to empty.
The third step is to put a quality wallpaper on the paving. Generally, there are various patterns. When laying, you must pay attention to whether there is a large gap between the two wallpapers, and whether the mosaic is aligned. In addition, watering the tiles during the paving will wet the wallpaper, and there will be some shrinkage after drying. The shrinkage seam of the wall should not open to the windward opening as much as possible.
The fourth step is not to forget to keep the windows and doors open during the 24 hours of continuous maintenance and construction. Excessive ventilation caused the wallpaper to dry quickly and shrink unevenly, causing cracks in the joints. After 3 days of paving, pay attention to adjusting ventilation. In order to prevent moisture from entering, doors and windows should be opened during the day to keep ventilation, and doors and windows should be closed at night.
