In recent years, more and more people have turned to using wallpapers to enhance the look of their homes. With its soft texture and ability to create a warm and inviting atmosphere, wallpaper has become a popular choice for interior decoration. However, while many focus on the design and style, most consumers are not fully aware of the key factors involved in purchasing and installing quality wallpaper. So, how can you choose the right wallpaper and avoid common pitfalls like peeling or bubbling? To help you make informed decisions, we've consulted experts who share their insights on what to look for when buying wallpaper—so you no longer feel like a beginner in this area.

**Environmental Protection Should Be Your Top Priority**
Experts emphasize that the quality of a wallpaper is largely determined by its material. While aesthetics matter, environmental safety should be your primary concern. The materials used directly affect the wallpaper’s eco-friendliness. Common types available in the market include PVC wallpapers, plain paper wallpapers, diatomite wallpapers, wood fiber wallpapers, and natural fabric wallpapers. Among these, PVC is the most widely used due to its affordability and durability.
PVC wallpapers offer vibrant colors, are resistant to scrubbing, aging, and fading, making them a popular choice. However, they are also prone to issues like curling, bubbling, and mold growth. On the other hand, pure paper wallpapers are more environmentally friendly since they are made from natural materials like grass, bark, and wood pulp. Diatomite wallpapers are another great option, as their porous surface helps absorb harmful substances and odors from the air, improving indoor air quality.
**Price Depends on Material Quality**
The price of wallpaper varies significantly based on the materials used. Domestic wallpapers typically range from 100 to 300 yuan per roll, while imported European or American wallpapers, often made from pure pulp, can cost over 300 yuan, sometimes even reaching 1,000 yuan per roll. The standard size is usually 0.53 meters wide by 10 meters long, which equals 5.3 square meters per roll. Keep in mind that there may be some wastage during installation—about 15%—so it's important to calculate the required amount accurately before starting.
For higher-end options, it's best to use them in areas like the bedroom where aesthetics and comfort are key. Domestic or joint-venture brands may be more budget-friendly, though they might not use 100% pure pulp. Still, they can be a practical choice for general home use.
**[Tip] The Wall Base Is Crucial for Proper Installation**
Many people think that applying wallpaper is simpler than painting and keeps walls cleaner. But in reality, the success of your wallpaper depends heavily on the condition of the wall base. Before applying any wallpaper, ensure the wall is properly prepared.
First, check if the wall is flat. You can use a two-meter ruler or shine a flashlight across the surface. If there are no obvious irregularities, it’s a good sign. Next, test the wall’s load-bearing capacity. Try sticking a piece of tape on the plaster. If it comes off without pulling away any plaster, the wall is suitable. Also, check the pH level—it should be neutral. Use pH test paper for this.
Additionally, the wall should be clean, with consistent color and smooth texture. Different wallpapers have different requirements, but all need a properly prepared surface. Finally, ensure the wall is dry. The moisture content of wooden boards should not exceed 8%, and for walls, it should be under 12%.
