First, the advantages of using wallpaper 1. The decorative effect is strong: the wallpaper has a wide variety of colors and patterns, and the choice is large. The effect after decoration is rich and colorful, which makes the home more warm and harmonious. With improved pigment formulations, the current wallpaper has solved the fading problem. 2. Wide application range: The base material can be used for cement, wood and powder wall, which is easy to keep in harmony with the color and style of interior decoration. 3. Convenient maintenance: The wallpaper has good scrub resistance, the cleaner is clean water, easy to clean, and has good renewal performance. 4. Safe to use: The wallpaper has certain sound absorption, heat insulation, anti-mildew and anti-bacterial functions, and has good anti-aging and anti-insect functions, non-toxic and non-polluting. 5. Wallpaper has a strong decorative effect, and different styles of wallpaper can often create a different personality space. Whether it is simple style, rustic style, rural style or Chinese, Western, classical, modern, wallpaper can create a new feeling, which is not possible with latex paint or other wall materials. 6. The paving time of the wallpaper is short, which can greatly shorten the construction period. 7. The wallpaper has relatively good wear resistance, anti-pollution, and is easy to clean. 8. The wallpaper has a crack-proof function. Latex paint on the insulation board, whether it is added to the good cloth or bandage, not long after the delivery, some cracks will be revealed, and the wallpaper can play a good role in avoiding this defect. As long as the paving is in place, the small cracks will not appear again. Of course, if the quality of the building has a large thermal insulation wall, no matter what the decoration can be cracked. Second, common wall problems and solutions to wall problems 1. Powder wall: There is a weak powder on the wall surface, which should be removed by sanding, leveling, brushing varnish or wallpaper base film with higher environmental performance. After drying, the wallpaper can be pasted. 2. Light wall: the wall surface is very smooth, it is not easy to absorb the glue, it is not easy to dry, then the force will drop, and it needs to be sanded to paste the wallpaper. 3. Make-up putty: Add more white glue to the putty to make it firm and not crack. 4. Batch putty: Add a small amount of white glue to the putty for sanding. Important note: Gypsum powder plus white glue instead of batch putty can speed up drying and shorten construction time. 5. The main process of plasterboard surface wallpaper: Cleaning, filling gaps, sanding sanding----season paste----finishing putty, sandpaper grinding----brushing the bottom of the glue----wall marking line---- wallpaper brush adhesive- ---Basic brush adhesive----Wallpaper paste----stitching, lap jointing, flower----pressure adhesive and air bubble----wipe the extruded glue----cleaning and trimming 6. Treatment of damp wall surface: The walls of the living room are moist and even moldy. At this time, the anti-seepage liquid can be applied to the wall surface to form a colorless and transparent waterproof film layer on the wall surface, thereby preventing the intrusion of external moisture, keeping the wall surface dry, and then the wall surface can be decorated. If the wall has been damp, first let the damp wall surface dry for one to two months, then apply a layer of cement-proof water-repellent slurry on the wall to prevent moisture. Next, fill the wall pit with gypsum putty. After drying, sand the wall with sandpaper. Then, the primer can be coated twice with the paint roller on the dry and clean wall surface, or sprayed. Third, the wall construction requirements Before the wallpaper is pasted, the quality of the base treatment shall meet the following requirements in accordance with the National Standard for the Acceptance of Quality of Building Decoration Engineering (GB50210-2001) of the People's Republic of China: 1. The concrete or plaster base wall of the new building should be coated with an alkali-resistant primer before the putty is scraped. 2. The old wall should be cleaned of loose old decoration layer before painting, and the interface agent should be painted. 3. The moisture content of the concrete or plaster base shall not exceed 8%; the moisture content of the wood base shall not exceed 12%. 4. The bonding strength of the base layer putty should be flat, firm, firm, non-powdered, peeling and cracked putty should comply with the N type of "Building Interior Putty" (JG/T3049). Fourth, after the completion of the construction of the wallpaper, what should be noted to protect the wallpaper? 1. After the wallpaper is pasted, the doors and windows should be closed for 2-3 days to make the wallpaper dry naturally. Remember not to turn on air conditioners such as heating to avoid the seams from being severely shrunk. 2. During the wet season, doors and windows should be opened during the day to prevent moisture from invading. 3, the wallpaper has a certain scrub resistance, so if stained, can be gently wiped with soap or other cleaning agents. 4. For wallpapers with embossed patterns, clean them with a vacuum cleaner every 2-3 months. 5. Be careful not to hit or rub the wall with hard objects such as the back of the chair or the table to avoid damage to the wall. In this way, the room you decorate with wallpaper will maintain a beautiful and clean effect after several years. 5. Is there any skill in choosing the pattern and color of the wallpaper? Choosing a pattern and color is a painstaking task. Here we can make some simple introductions for customers' reference. 1. The color of the wallpaper can affect people's emotions. Warm colors and bright colors have an active effect on people's emotions. They are suitable for use in restaurants and living rooms. Cool colors and low-light colors can make people concentrate and calm, suitable for use in the study. 2. The vertical stripe pattern increases the height of the room. The strip-shaped wallpaper has many characteristics such as permanence, classicity, modernity and tradition. It is one of the most successful choices. It can spread the color on the entire wall in the most effective way, and it is simple and elegant. It is very easy to match other patterns. The slightly wide stripe is suitable for use in a large, fluent space, allowing the original tall room to extend to the left and right; the narrower pattern is better for small rooms, which can make shorter rooms The effect of the upward guidance. 3, the large flower pattern reduces the sense of restraint in the living room. Some of the flower patterns are realistic and colorful, and the distant view is really a feeling of coming out. This kind of wallpaper can reduce the restraint of the room and is suitable for rooms with a relatively flat pattern. Because most of these patterns are more exaggerated, they should generally be paired with European classical furniture. People who like modern simple furniture should not use this wallpaper. 4, the pattern of small regularity adds a sense of order in the living room. Regular small patterns can provide a background that is neither exaggerated nor too dull. Your favorite furniture will fully reveal its characteristics in front of this background. If you are choosing the wallpaper for the first time, choose this type of wallpaper. Safety. How to maintain and maintain the wallpaper? Generally, the wallpaper has a longer service life than the latex paint, because the plain surface of the latex paint is extremely dirty, and the scrubbing process is unlikely to have no effect on the wall surface. The wallpaper is not the case, the maintenance is good, it can be kept for 10D15 years. Therefore, the maintenance and maintenance of the wallpaper is the key. 1. When the cloth is constructed, it should be chosen to avoid the construction in the wet season and the wet wall when the relative humidity of the air is below 85% and the temperature should not change drastically. 2. During construction, doors and windows should be opened during the day to keep ventilation; at night, doors and windows should be closed to prevent moisture from entering. The wallpaper that has just been attached to the wall prohibits the strong wind from blowing, which will affect the bonding fastness and extremely surface engineering. 3, the adhesive liquid overflowing when the wallpaper is pasted, should be cleaned with a clean towel at any time, especially the glue marks at the seams, to be clean. This is a construction worker or supervisor must be carefully and carefully reviewed. The construction personnel keep the hands and tools clean and smudged. They should be cleaned with soapy water or detergent in a timely manner. 4, foam wall cloth is easy to accumulate ash, affecting the appearance and cleanliness, cleaning every 3D6 months. Wipe clean with a vacuum cleaner or a brush, taking care not to allow water to seep into the seams. 5, usually pay attention to prevent hard objects from hitting and rubbing the wall. After a certain period of time, the joints in some places will be cracked, and subsidies should be provided in a timely manner.
