Wallpaper moisture-proof details grab

To do a good job of moisture-proof wallpaper, we must start from the time of decoration, and lay a good foundation to effectively avoid many troubles in the future. The first step is to select breathable materials. At present, there are many wallpaper materials on the market, such as non-woven fabrics, wood fibers, PVC, cloth surfaces, etc. Relatively Speaking, PVC wallpaper is the most airtight and is the easiest to suffocate the water vapor discharged from the wall, after a long time, it is easy to form mildew spots. The second step is to keep the wall dry. The wall surface must be kept dry, and the construction of new cement usually takes 20 to 40 days to be able to lay wallpaper. Before posting wallpaper, you need to handle the base surface first. The third step is to check the quality of the paving. Wallpapers generally have various patterns. When laying, you must pay attention to whether there is a large gap between the two wallpapers and whether the flowers are aligned. In addition, watering will wet the wallpaper when paving, and there will be a certain contraction after drying, so keep the telescopic position. The shrinkage joints of the wall should not be opened to the windward opening as far as possible. The fourth step, do not forget to maintain. Do not open all windows and doors during construction and within 24 hours after construction. Ventilation will cause the wallpaper to dry sharply and shrink unevenly, causing cracks at the joints.
