People who like wallpaper often have such a worry: Will the wallpaper curl? Are all the wallpapers curled? In fact, not all wallpapers will be curled, depending on the selected wallpaper material.
The material of the wallpaper is divided into two major categories: wallpapers of PVC materials and plain paper materials. Under normal circumstances, PVC material wallpaper is easier to curl. This is because the wallpaper of PVC material is composed of PVC material and paper base. This kind of wallpaper has a strong texture when touched, but because it is layered, the paper base will be partially affixed to the wall due to various reasons. Expansion, and the paper surface of the PVC material does not expand due to water, so the paper base expands outwardly and the paper surface does not expand at the same time, so it is easy to cause curling. At the same time, the wallpaper of the PVC material has a relatively large elasticity with changes in the temperature, and the change of the paper base with the temperature is relatively small, which also easily causes curling of the PVC material. In addition, because the PVC material of the wallpaper is not airtight, the wall and the construction process of moisture are trapped in the inside, just like wearing a plastic clothes, once the conditions are right, it is easy to produce bubbles and mildew.
The pure wood pulp and wood fiber wallpapers of pure natural materials consist of wood and wood fibres, which are consistent with the changes of water and temperature, and the breathability of this material is also very good. The moisture in the wall and construction process is naturally drained to the outside, so it is not easy to curl, and it does not cause bubbles and mildew because of the weather.
