Wallpaper construction method:
A, building wall requirements
Wall treatment must be clean, flat, firm, smooth, uniform in color and neutral in pH value. The wall is completely dry, and the water absorption rate is not more than 8%. In the construction of paper-based wallpaper, it is recommended to use the wallpaper basement membrane, evenly coat it on the wall, and dry it thoroughly before construction.
Inspection method of wall dryness: you can use transparent film to cling to the wall, seal the four sides with adhesive tape after leveling, and observe the wall after 24 hours. If condensed water drops appear, it means that the wall is not dry enough and needs further drying.
If the other side of the wall is the bathroom, the wall must be waterproof and mildew-proof. If the wall is wet or moldy, it should be scrubbed with bactericide and treated with varnish to prevent it from getting wet.
If the building technology is limited, the wall that emits moisture from the ground is not suitable for wallpaper.
Second, building tools.
1, soft and hard scraper 2, plumb line 3, cutting ruler 4, gluing brush 5, ladder 6, glue mixing barrel 7, white towel 8, tape measure 9, leveling brush 10, wool roller brush 1 1, external angle roller 12, wallpaper knife.
Three. Architecture-wallpaper cutting
Prepare a platform equivalent to the cutting length, and spread clean paper on the platform for use when cutting paper and brushing glue.
Open the wallpaper box: make sure that the wallpaper models are correct, belong to the same batch number, and are arranged in the order of volume numbers. After unpacking, look for the construction instructions to see if there are any instructions for turning around, direct horizontal alignment, dislocation alignment and arbitrary alignment.
Pattern direction: first determine the direction of the pattern and distinguish between the top and bottom.
Wall height measurement: Take the top of footstone as the starting point, and measure the wall height with steel tape measure.
Paper cutting length: paper cutting should be carried out according to the requirements of wall height and mosaic, which is generally 10cm longer than the actual height, so as to correct it up and down. For wallpaper with obvious mosaic patterns, it is best to mosaic before cutting, and at the same time indicate the direction, order and horizontal splicing on the back of the paper. If the unit of the pattern is relatively large, you must leave a pattern with a unit length when cutting. Cut according to the order of box number and volume number of the product.
Four. Architecture-glue mixing and painting
Please invite a professional construction team with construction experience or a construction team funded by decoration to carry out the construction. Please give priority to the rubber powder and mucilage matched by our company or choose high-quality professional wallpaper rubber powder, carefully read the instruction manual of rubber powder and adjust the glue.
Mixing glue solution: when mixing glue solution, first pour a specified amount of cold water into the bucket, slowly add wallpaper glue powder, and stir evenly in the same direction without caking. It takes 20 minutes to use after mixing.
Viscosity of glue solution: insert a bamboo chopstick vertically into the glue solution, and the chopstick can be considered as having a proper viscosity without falling off.
Glue coating: For non-woven paper-based products, glue should be directly coated on the wall, and other wallpaper glue should be evenly coated on the quilt cover. If possible, you can use a glue machine to glue. After gluing, both sides of the wallpaper should be flattened and placed in a stuffy place. Before construction, the glue should fully penetrate the base paper to fully soften the base paper. Generally, it takes about 3- 10 minutes, and the soaking time of all wallpapers must be the same. The thickness and grammage of base paper are different, and the softening time is also different. The thicker the base paper, the longer the softening time.
Verb (abbreviation of verb) architecture-wallpaper pasting
1. Determine the position of the first wallpaper. Generally, start from the internal corner of the wall and draw a vertical line on the wall (about the width of a wallpaper from the wall). Don't build more than two places in the same room at the same time.
2. After pasting the wallpaper on the wall, you need to use a special wallpaper roller to roll the bubbles out in the same direction. Don't forcibly squeeze the slurry from the edge of the paper tape and sprinkle it on the wallpaper surface. Scrape the part near the roof and the ground with a scraper, drive out the bubbles, make the wallpaper close to the wall, and cut off the excess wallpaper at the same time.
3. Don't use a scraper to scrape and press the wallpaper in a large area, so as not to damage the wallpaper surface or squeeze some glue from the edge of the wallpaper and sprinkle it on the wallpaper surface, resulting in loose wallpaper paste, cracked seams and dirt.
4. The edge seams of two wallpapers need to be rolled by oblique seam rollers, so that the wallpapers can be pasted firmly and the seams will not crack. If you accidentally spill glue on the surface of the wallpaper, you must thoroughly remove the excess glue on the wallpaper with a wet towel or sponge in time, and do not smear it back and forth, otherwise the wallpaper will leave white marks after drying.
5. The switch box or other decorations protruding from the wall should be removed after the power failure, and then installed after the construction is completed. Finally, cut off the extra wallpaper at the edge.
6. It is suggested that the room temperature for the construction of glued wallpaper should be around 65438 08℃. Too cold or too hot will affect the construction quality. Avoid ventilation and rapid ventilation after posting and before drying.
