Problems that are easy to produce in wallpaper paving
In the wallpaper paving, it is easy to open the glue, the mosaic is not uniform, the seam is yellowed and so on. The main reason is that most of the construction workers in China have not been professionally trained, and the quality of workers is generally not high. In addition, the lack of understanding of the characteristics of the wallpaper by the workers is also the main reason for the opening of the glue, the unevenness of the flowers, and the yellowing of the seams.
Construction points of the wallpaper
Remove the original paint on the wall (renovation effect map), wallpaper and other objects; if there are cracks and potholes on the wall, use gypsum powder to fill these places, put a bandage on the flat surface; Gray walls, partition walls, but also full of glass cloth or a good cloth; some poor quality partition wall or external wall to achieve the effect of insulation, full of gypsum board;
Brush base oil: evenly brush the alkyd varnish on the wall, the thickness is moderate;
Putty putty and sanding: Put the putty on the wall twice. After the putty is dried, sand the wall with sandpaper, and rub the uneven particles to make the wall smooth and flat;
Cover oil: Paint the wall evenly with clear oil, no need to be too thick. This prevents the wall from absorbing wallpaper glue, making the wallpaper stick to the wall and making the wall flatter;
Cropping wallpaper: Cropping wallpapers also has regularity, such as the problem of each wallpaper and the two adjacent wallpapers, the uniformity of the patterns, the uniform size, etc.
Post wallpaper: After applying the wallpaper glue evenly to the wallpaper with a roller, it needs to be placed for a thicker wallpaper for a while. When you start to affix the wallpaper, for the seams, the two sides of the adjacent wallpaper are squeezed together to make them match, and then the seam is pressed with the squeegee and the extruded glue is cleaned. After the wallpaper is pasted, use the scraper to flatten the wallpaper from top to bottom.
How to avoid the above problems
First of all, there must be professional construction tools, such as roller, brush, roller, professional knives, etc.; workers should be familiar with the characteristics of the wallpaper, especially for pure paper, diatomaceous earth or rough surface wallpaper, must pay attention to the paving When the residual glue is not left at the seam, if the residual glue is not clean, the phenomenon of opening the glue and yellowing will occur in the future; for the corners, the professional edge sealing glue should be used to avoid cracking; When it is time to be neat, the tool must be cut when it is cut.
