Wallpaper is a popular wall covering material that adds coziness and style to the interior. However, some situations can lead to the problem of yellowing wallpaper. In this post, we will look at a few factors that can be the cause of yellowing wallpaper and offer some recommendations on how to prevent this problem.
Yellowing wallpaper can be caused by a variety of factors. Here are a few of them:
1. Poor removal of the previous wall covering: If the previous wall covering was improperly removed or glue residue is left behind, this can lead to the problem of yellowing of new wallpaper.
2. Metal objects in the wall: If metal objects such as nails or staples are left in the wall that were not removed before wallpapering, they can cause oxidation and lead to yellowing of the wallpaper in these areas.
3. Chemical wall treatments: If walls have been chemically treated with products containing copper compounds or other reagents, this can also cause wallpaper to yellow.
4. Uneven application of adhesive: If the adhesive is applied unevenly to the wall surface, there may be problems with the adhesion of the wallpaper, which may cause it to yellow.
5. Low-quality long-drying adhesive: Using a low-quality long-drying adhesive can also cause wallpaper yellowing, as the poor quality ingredients in the adhesive can cause oxidation and discoloration.
6. High humidity: Too much humidity in a room can encourage mold or fungus to grow on the wall, which can result in yellowing wallpaper.
To avoid the problem of yellowing wallpaper, it is recommended to properly remove the previous coating, clean the walls from metal objects, use a quality adhesive and control the humidity level in the room. If the problem occurs, you should contact professionals for advice and recommendations on the correct solution.
