If there is water seepage on the wall or the indoor humidity is too high, the wallpaper will be damp and moldy, black spots will appear, and in severe cases, a large area will be blackened. In addition, wallpaper is not resistant to scrubbing, has a short service life, and is easily scratched. Improper construction will cause problems such as warping, blistering, and falling off. There are obvious seams, easy to warp the edge, overflow glue, yellow, and easy to discolor. The flame retardant performance is low, and the combustion releases toxic substances. The service life is short, general 3-4 years, cannot be updated, and the cost of re-installation is high. Three-dimensional sense, the overall effect is not strong.
It is difficult to take care of, long-term use will cause seams to warp, the color fades over time, and it is not easy to clean after being polluted, and the cleaning requirements are high. The loss is relatively large, During the decoration, the wall cloth cut according to the size of doors and windows have basically no other purposes. For some houses with many doors and windows, a lot of cloth is removed, which is a waste of resources. The surface of the wall cloth is cloth, and the elasticity of the cloth is larger than that of the paper. If the skill of the workers is not good and the force of the wall cloth is uneven when it is posted, it is easy to appear that the pattern distribution is not on the same horizontal or vertical line, which will affect the paving effect. And because of its thicker material, the gaps spliced out will be more obvious than the wallpaper.
Easy to crack, easy to fall off and fade, and the repair effect is poor. Cannot be scrubbed and repainting is expensive. The color matching is single, with chemical material, the environmental protection performance is average. And it contains a strong irritating odor, which is unbearable. The gas contains a lot of harmful substances, which are harmful to human health. The paint film is harder and more brittle, and it is not easy to repair after damage and is extremely flammable.
Beautiful from a distance, rough up close. Difficult to clean, strong adsorption, very difficult to clean the stains. Diatom mud is non-waterproof. Once wiped with water, it may be directly absorbed into the molecular structure and cannot be cleaned. It is not suitable for places that are too humid, such as kitchens and bathrooms. Low hardness, easily broken into small pieces after the collision. The price is expensive. The hand feel is not good, and the diatom mud feels rough and uneven.
