The main processing steps of the grassroots layer of the wallpaper are introduced :
1. It's essential to ensure that the moisture content of the wall base is below 8%-10% before proceeding with any wallpaper installation. This helps prevent future issues like peeling or mold growth.
2. Before applying the putty, the wall surface must be solid and free from alkali, hollow sounds, and flaking. A stable base ensures better adhesion and a longer-lasting finish.
3. After cleaning the wall and removing any deposits, apply putty two to three times, sand it smooth, and wipe the surface with a clean cloth for a perfect finish.
4. Apply the wallpaper primer film after painting the wall. This step is crucial as it creates a protective barrier between the wall and the wallpaper.
The wallpaper base film is an essential material used during the wallpaper installation process. In the past, varnish was commonly used, but today, the base film has become the preferred choice. Applying a layer of this film on the wall before pasting the wallpaper helps create a dense protective layer. This prevents water and alkaline substances from seeping through the wall, which can cause damage, mildew, or discoloration. As a result, the wallpaper lasts longer and maintains its appearance. Compared to traditional varnishes, the wallpaper base film offers stronger adhesion, a smoother and more durable protective layer, and is resistant to aging, cracking, and mold. It is also environmentally friendly, free from harmful odors and formaldehyde, making it a safer option for your home. Additionally, the base film dries faster than conventional oil-based varnishes, saving time during the renovation process.
5. When painting the wall surface, you should never directly paste the wallpaper onto the wall. Instead, remove the old base, apply putty, then brush on the wallpaper base film and allow it to dry completely before starting the wallpapering process.
6. When working on an old wall, the quality of the existing putty may not be ideal. Therefore, it’s important to prepare the surface properly before pasting the wallpaper. Make sure all areas are cleaned thoroughly, and close doors and windows during the process. The ambient temperature should be at least 10°C, and humidity levels should remain moderate. After pasting the wallpaper, keep the doors and windows closed for 1 to 3 days to allow proper drying. Once fully dry, open the windows for ventilation to ensure a fresh and healthy environment.
