Analysis of the causes of wallpaper warping: There are many factors that constitute wallpaper warping, and they are related to each other to varying degrees. It is necessary to integrate various information and analyze the essence of the problem in order to draw the correct conclusion. The factors that lead to the warping of the wallpaper and the opening of the seam can generally be summarized as the following two reasons:
1. Human factors: improper construction of wallpaper
①Sun exposure and strong wind blowing will cause the glue to dry too fast, shrink unevenly, and crack locally;
②The softening time is too long after the wallpaper is glued. Expansion is too long, forming shrinkage joints after drying
③The glue concentration is too low, the stickiness is insufficient, and the wallpaper cannot be stuck
④ Too much local glutinous rice glue, uneven shrinkage:
⑤ The scraper is too forceful when pasting, or the wallpaper is stretched and widened too much during construction, resulting in excessive stretching, and the wallpaper shrinks to form a shrinkage joint after drying:
⑥ The knife edge is repeated during double-layer cutting, resulting in too obvious gap.
⑦The seam is not strict when pasting the wallpaper.
2. Improper wallpaper and glue products: including improper selection of products and improper deployment of products.
Before construction, you should first evaluate the wallpaper to be constructed. It is best to do a paste test in advance, choose a suitable wallpaper adhesive brand, and do not rely on experience.
① Improper selection of products, for example, without a reasonable assessment of whether the selected products are qualified, and directly selecting products whose performance cannot meet the requirements to paste wallpaper, such as using wallpaper glue with normal performance to paste (heavy) wallpaper, it is prone to problems: Non-woven wallpaper, because it is a type of wallpaper with strong shrinkage, should use wallpaper adhesive products with strong adhesion, such as special wallpaper glutinous rice glue.
②Adjustment of glue: Improper application, including: the amount of glue mixed with water is not in accordance with the packaging instructions, adding too much or too little water: the time of glue mixing for wallpaper glue is too short, the stirring is uneven, it is not completely gelatinized, and the adhesive force is not good: workers Improper method of mixing glue, resulting in lumps, low viscosity of glutinous rice glue, etc.
③Stability of glue: It means that the product has poor stability and is prone to abnormal quality. When using wallpaper glue with low product performance and low viscosity and viscosity to paste wallpaper, it will inevitably affect the quality of wallpaper construction.
④Environmental factors: including the temperature and humidity conditions of construction. The firmness of the base layer of the wall (putty wall), the smoothness and water absorption of the wall, the sealing effect of the wall, the bearing capacity of the construction surface, etc. Blind construction when the environmental conditions do not allow it will inevitably lead to problems. .
Finally, let’s talk about the maintenance methods for warped edges or seams in the wallpaper. The maintenance methods vary according to the material of the wallpaper. Generally speaking, pure paper wallpaper and pvc wallpaper: Wet the seams with a towel, uncover the wallpaper after 4-5 minutes, and then Brush glue to re-paste the wallpaper;
Non-woven and velvet fiber wallpaper: wallpaper without swelling can generally be torn off in its entirety, first peel off the wallpaper, gently stretch it with your thumb and forefinger in turn, then apply glue and paste it. After repairing, let it dry slowly in the shade. Sun exposure or strong winds.
