Hard injury 1. The face of wallpaper "turns over when you say it"

Why did the wallpaper fall off in a few days? Wallpapers with good quality and workmanship can generally be guaranteed not to peel for at least 5 years, if they are just pasted. First of all, check whether the front is too wet and whether there is water seepage. Secondly, check whether the glue for wallpaper meets the requirements. Finally, check whether the front is flat and smooth. All of the above three factors may cause wallpaper to turn against each other.

Hard injury 2. The face of wallpaper "became fat" overnight. The beautiful wallpaper bubbled overnight, and the perfect face was too fat to recognize. Why is this? Wallpaper foaming should first check whether the glue on the wall is evenly coated. If the coating is uneven or missed, it will cause the wallpaper to bubble.

At this time, you can use the "face-lifting needle" to fix it. First, puncture the bubble with a needle to discharge gas, then inject an appropriate amount of glue with a needle, and finally scrape the wallpaper. Restaurant wallpaper picture 2

Hard wound 3. The face of wallpaper "cracks when you say it"

Cracks in wallpaper are usually caused by incorrect pasting method or unqualified adhesive. Therefore, in addition to finding a reliable teacher, we should also choose glue with good adhesion and fast drying. After the wallpaper is pasted, the glue will dry thoroughly before the wallpaper shrinks obviously, which can effectively avoid the wallpaper from cracking.

The discoloration of wallpaper mainly refers to the yellowing, blackening or other colors of wallpaper. The discoloration of wallpaper is generally due to the discoloration of glue and basement membrane, which leads to the discoloration of wallpaper. The importance of glue in wallpaper can be seen. Also, when choosing wallpaper, try to avoid choosing white, beige and other plain wallpaper, which is easy to change color.

Five, the face of wallpaper "donkey's head is not right"

In the process of pasting wallpaper, many people don't match patterns. This is the most common mistake that many beginners make when pasting wallpaper, so before pasting wallpaper, we should carefully check whether the size, color and pattern of wallpaper are regular.

Six, wallpaper "different colors"

The biggest fear of wallpaper pasting is that it is not enough and you need to buy wallpaper again. Then the newly bought wallpaper may have color difference with the previous wallpaper, so it is very important to mark the model and batch number of the wallpaper in advance. In addition, the wall area should be accurately measured before pasting wallpaper, and the possibility of paper shortage should be strangled in the cradle.
