Compared with wall paint, wallpaper has the advantages of rich pattern, convenient replacement, better air permeability and more environmental protection. Therefore, many owners prefer to choose the former when they like the high-end feeling and do not care too much about the price. The laying process of the wallpaper directly affects the visual effects after completion and the future maintenance. This article will introduce you to the whole process and precautions.
If the wallpaper is not attached, don’t worry about a few practical remedies to teach you
Preliminary preparation
1, wall treatment
If there are seams on the wall, you need to use the putty to make up the seam first. Use the putty to add more white glue (vinyl acetate resin), and then fill it up after the seam is repaired. If there is any weak powder or dust on the wall, it should be removed by sanding. An overly smooth wall is not easy to absorb glue, then the force will drop, and it must be sanded before it can be wallpapered. After the above process is completed, a base film is required to form a protective film between the wall surface and the wallpaper, which not only stably protects the wall surface, but also prevents moisture, salt and alkali from infiltrating the wallpaper, and effectively protects the decoration material from mold. .
2, glue preparation
The glue is generally made of a mixture of wallpaper rubber powder and white glue, and the viscosity is appropriate, and it is easy to brush. The viscosity is adjusted by the amount of water added. The wallpaper powder is natural starch, and the white glue is synthetic resin (vinyl acetate resin). In order to ensure good wallpaper paste effect, different amounts of white glue are often added according to different wallpapers. The cloth base surface cloth is thicker and thicker. The glue preparation is thicker than other wallpapers. It can be prepared with white glue and wall powder below 15 ounces. The special glue for wall cloth can be used for 15 ounces or more. The special glue can be used for 5 square meters per kilogram. Meter.
3, wallpaper cutting
Use a roll of wallpaper to open and check the pattern, pattern, direction, determine which direction is facing up, use the top of the kicking floor tile as the starting point, use the tape measure to measure the wall height, then spread the wallpaper on the table, the glue is facing up, With the face down, measure the length, use a pencil to draw a line on the back, and then cut it with a pair of scissors. According to the wall framing size, according to the wallpaper pattern parquet requirements, cut the paper, edit the corresponding number, and reserve 30---50MM for cutting at both ends, and lay it flat.
Mid-term construction
The roller for the glue is soaked in the prepared glue for 30 seconds. When the roller is brushed, it should be rolled in the same direction, and the roller and the wallpaper should be gently rolled at 45 degrees. You can't roll back and forth, it's easy to wrinkle the wallpaper. When painting, the action should be smooth, the force is even, the roller should be taken in one hand, and the other hand should be fixed in the place where the glue is not brushed; After all, use a small brush to apply a special glue (the ratio of wallpaper powder to white glue 1:1) at the edge of the wallpaper.
After smearing the wallpaper and applying it to the wall, it must be smoothed to remove the bubbles. Generally, the rubber surface wallpaper is more resistant to water washing, so you can use the “plastic scraper†to gently scrape the surface and drive out the air bubbles. If a small amount of glue is driven out of the surface, it should be wiped clean with a wet sponge. The scraper should not be too hard, otherwise it will be easy to scrape. The surface of the wound causes defects such as fading, reflection, and seams. The surface of high-grade textile wall covering is susceptible to damage. As long as it is lightly brushed with a short brush, and the amount of glue is appropriate, the glue must not be driven out of the joint and contaminate the surface, otherwise it cannot be disposed of. Paper wallpaper is very delicate, only use short brush, should avoid the glue on the surface, if you accidentally touch the surface should be wiped clean immediately, otherwise the glue can not be removed after drying, and will cause chromatic aberration. When any wallpaper is constructed, the glue should not touch the surface of the wallpaper, which is the perfect construction process.
Late inspection:
1) Whether the seams are aligned or curled.
2) Is there a bubble?
3) Whether the pattern does not match.
4) Crease
Remedy:
1. Seam loosening: Use a knife to pick up the seam, inject glue from the slit, use a scraper to level it, and wipe off excess glue.
2. Bubble: Cut with a utility knife, inject glue into the opening, use a suitable plate to smooth, wipe off excess glue.
3, the pattern does not match: due to inaccurate buildings, such as uneven settlement of the foundation, etc., causing the flower can not appear in the inconspicuous corner.
4, the crease: cut the crease with a utility knife, add glue, use a roller to roll flat, if not flat, use the "refill" method.
5, wet plaque: usually do not see wallpaper defects; and may be a problem with the wall, to ask the relevant experts.
6, black spots: black spots mostly indicate problems with the wall such as: mold, water, etc.; remove the wallpaper to deal with the moisture part, and then apply mildew glue.
