There are many factors that make up the edge of wallpaper, and they are related to each other to different degrees. It is necessary to synthesize various information and analyze the essence of the problem in order to draw a correct conclusion. The factors that cause the wallpaper to be warped and seam can be roughly summarized as the following two reasons:
1. Human factors: improper wallpaper construction
Sunlight and strong wind will cause the glue to dry too fast, shrink unevenly, and locally crack;
The softening time of wallpaper after brushing is too long. Expansion is too long, and shrinkage joints are formed after drying
The glue concentration is too low and the adhesion is not enough to stick to the wallpaper
Local glutinous rice has too much glue and uneven shrinkage:
Lax to seam when pasting wallpaper.

2. Improper wallpaper and glue products: Including improper selection of products and improper deployment of products.
Improper selection of products, for example: Failure to reasonably evaluate whether the selected product is qualified, but directly selecting products with performance that cannot meet the requirements to paste wallpaper, such as pasting (heavy) wallpaper with ordinary wallpaper glue, it is prone to problems: none For textile wallpaper, since it is a type of wallpaper with strong shrinkage, it should use a wallpaper glue product with strong adhesion, such as a special glutinous rice glue for wallpaper.
Glue blending: improper application, including: the amount of glue added to the water is not in accordance with the packaging instructions, too much or too little water: the time for wallpaper glue is too short, the mixing is uneven, it is not completely gelatinized, and the adhesion performance is poor: workers adjust Improper glue method can cause throwing and low viscosity of glutinous rice glue.
Glue stability: refers to the poor product stability, which is prone to abnormal quality. When the product performance declines, the viscosity and viscosity of the wallpaper glue are used to paste the wallpaper, it will inevitably affect the quality of the wallpaper construction.
Finally, let’s talk about the repair methods for the warped edges or slits of the wallpaper. The repair methods vary according to the material of the wallpaper. Generally speaking, pure paper wallpaper and pvc wallpaper: moisten the seams with a towel, uncover the wallpaper after 4 to 5 minutes, and then Brush the glue and re-paste the wallpaper.
