Therefore, it is used more in certain environments, such as cartoon wallpaper for children's room, flower and bird wallpaper for bedroom, and landscape wallpaper for study. The other pattern adopts an abstract approach and dominates the imported wallpaper. This kind of wallpaper looks disorganized when viewed alone, but the decorative effect after a large area is very good, especially suitable for use in the decoration of large spaces such as the living room.

When choosing a wallpaper for home decoration, the main choice is pattern and color. When wallpaper manufacturers produce wallpapers, each pattern will have different combinations of several colors.

It can be used only after mixing with water. It has fast hardening speed, high surface hardness, no cracking, no The advantages of falling powder, etc., the home decoration project mainly uses this putty for the leveling treatment of the base layer. When processing the surface of the base layer, first clean the base layer so that it is free of dust, oil, debris, and the like. Then, according to the actual situation of the base layer, the putty should be scraped. Generally, it should be scraped twice, until the base layer is smooth and smooth. After the putty is dried, it can be polished with fine sandpaper to remove the scratches and residual debris before the wallpaper can be pasted.

3, the paste of the wallpaper

Before you paste the wallpaper, you must first make a line 1. The bullet line is the base layer that has been processed. The upper horizontal line and the vertical line are used to make the paste have a basis to ensure the quality of the paste. The first line should be on the outside of the first wallpaper on the wall. The position should be set at the corner of the wall, which is less than 50-80 mm wide, so that the wallpaper can be placed at the corner of the wall. The line should be on the center line of the wall with the window to ensure the symmetry of the pattern of the corner of the window. The third line is to eject horizontal lines and control the level on the wall.

Paper cutting is an important part of wallpaper pasting. After measuring the height from the top of the wall to the bottom of the kicking, the paper should be cut on the ground. The blanking size of the wallpaper should be l0-20 mm longer than the actual size.

The first piece of paper should be pasted from the corner of the wall, straightened according to the vertical line of the bullet, gently flattened from top to bottom, pressed from the middle to the sides, and then scraped from top to bottom, from the middle Scrape to the sides to make the wallpaper and wall solid and smooth the wallpaper. The method of splicing the second wallpaper with the first wallpaper is that without the flower, the web overlap overlaps 20 mm, and the seam is compacted with a steel ruler from the top to the bottom with the wallpaper knife. Cut off, remove the remaining part and scrape with a scraper. When the flower is needed, overlap the two sheets of paper with the steel ruler, compact it with the steel ruler, cut it from the middle, remove the cut paper strip, and use the scraper. It can be scraped flat. The top of the wall and the kicking foot should be tightly seamed, there should be no gaps, and the squeegee should be compacted along the edge of the wall and the kicking foot, and then cut with a wallpaper knife and then flattened. The glue that is squeezed out when you paste the wallpaper should be wiped clean with a wet towel.

In the actual paste, the wallpaper has a reasonable loss of 10%-17%, and should be set aside when purchasing.
