What problems need to be noted in the end? Let's take a look. Good wallpaper to see if it can be wiped with a wet rag Today's home environment is more and more full of theme, a few walls or even just a wall, use the texture and texture of the wallpaper, coupled with the right furniture and accessories, you can create your favorite atmosphere. There are many types of wallpapers.

Home decorating to buy wallpaper, the main choice is the pattern and color, etc., according to the room environment and the use of different choices, but do not ignore health and environmental issues. Wallpaper can normally be used for 10 years Wallpaper is the most environmentally friendly material among decorative materials. It is not only harmless to the human body in use, but also does not pollute the environment from raw materials to finished products. Wallpaper adhesives are also very environmentally friendly and are made from grain starch. The first thing to consider when choosing a wallpaper is to consider the area of ​​the living room, the dimensions of the space, and the orientation of the room. In principle, wallpapers are suitable for posting in any room, from the living room to the bedroom to the kitchen, suitable wallpapers can be found. Second, the advantage of wallpaper is that it can decorate the room with different wallpapers, and the function of the room can be easily distinguished. Easy to use, durable, cleanable, easy to replace. Normal use for 10 years is no problem. Minor stains can be wiped off with a damp rag. Serious fumes, color, food residue, pen graffiti, etc. can be wiped off with a rag or toothbrush. Wallpapers are divided into different types based on their substrates: paper wallpaper, PVC wallpaper, foamed wallpaper, non-woven paper wallpaper, fabric wallpaper, cloth-based wallpaper, gold foil wallpaper, special wallpaper, and so on. There are many wallpaper specifications, and there are two common types on the market: 0.53m×10.05m and 0.70m×10.05m. Among them, 0.53 meters x 10.05 meters are more optional. The best choice for natural fiber wallpaper or full-paper wallpaper There are many factors that need to be considered when selecting a wallpaper. It can be selected according to the style of decoration, or it can be comprehensively considered according to material characteristics, room size, function, or orientation, etc. However, when using it, it is necessary to pay attention to coordination, especially in color. The selection and matching of patterns need to follow certain principles. 1. Whether you choose wallpaper or wall covering, you should consider three main aspects: fire prevention, color, and ease of cleaning. In recent years, wallpapers and wall coverings have been supplemented with fire-resistant materials, and some have added pest control, mildew-proof, sound-absorbing materials. These are undoubtedly important for consumers who want to upgrade their homes. 2. The wall is the largest space for the use of decorative materials in the living room. Therefore, the color scheme and pattern of the wallpaper are the main directions for selection. The blend of colors can convey the overall beauty, and the bright contrast can make the space lively and changeable. 3. It is a good consideration when selecting wallpapers. The easy-cleaning properties of the wallpaper include dust and water repellency. For example, whether the surface of the wallpaper can be directly wiped with a wet rag is a concern to the user. 4. Choose a wallpaper, be sure to see whether it meets the standards of "limited content of harmful substances in indoor decoration materials wallpaper". It is best to choose natural fiber wallpaper or full-paper wallpaper; also consider the environmental performance of wallpaper adhesive, choose a guarantee of credibility The brand-name adhesives, preferably water-based; before the wallpaper is applied, the paint must also comply with environmental standards. In many people's impressions, compared to paints, the wallpaper is more simple to put on and keep the wall clean and neat, but it is not. It is understood that the paving of the wallpaper has a lot to do with the substrate, different substrates need to be handled differently, and the processing needs to pay attention to many details. Want to stick wallpaper? It may not be as easy as you think. Compared to coatings, wallpapers are easier to apply Do not paint the new house For the wallpaper, if the material of the shop is different, the processing method it takes is different. If it is a new house wall wallpaper, the substrate is the simplest. The procedure is the same as the basic wall construction, except that it is not painted, that is, the interface layer is normally brushed in the plastering layer, and then the scraping can be scraped 2-3 times. Then you can carry out other bricklayers, oil workers and other decoration, wait until the completion of the wallpaper on the wall. Old house paint needs to be tested first If the original wall is painted with paint and you want to refurbish the wall, is it right on top of the wallpaper? In response to this problem, experts said that if it is the old house wall, some judgments need to be made. If the original paint is tight and there is no shedding, you can brush the base film directly on the top (wallpaper necessary materials, can strengthen the wall surface, increase the wallpaper adhesion, protect the wall when you remove), and directly paving the wallpaper. However, if the original coating is not stable, the original substrate needs to be removed. Wallpapers also have 6 things that must be unnoticed How to determine if you need to eradicate the original paint? The owner can self-test the paint. Take a wet towel (drinking the floor without drip) and fix it on the wall in a certain way. Look up the next morning. If there is no peeling on the wall, explain The wall surface treatment is very good, the combination is still very close, you can brush the base film directly on top, paving any wallpaper. If the wall appears blisters and other conditions, then the wall substrate instability. If the wallpaper is applied directly at this time, the wall adhesion is relatively low, and the wallpaper easily falls off. If all the walls are unstable, you will need to remove all the walls and shovel them to the plastering layer, then re-apply the interface agent and scrape the putty. If only part of the wall substrate is unstable, only part of the substrate needs to be removed, and the interface agent can be repainted to scrape the putty. After completing this part of the process, the entire wall should be screened with a wallpaper knife to form a net-like form. Generally speaking, the deeper the scratches, the smaller the squares and the better. “Because the original substrate is relatively smooth, the adhesion is relatively poor. By this method, the two kinds of putties can be connected together to ensure the stability of the substrate and reduce the possibility of wallpaper cracking.†Empty old wallpaper should be eradicated What if the original wall is covered with wallpaper? Can I pave the new wallpaper directly on the original wallpaper? Experts said that this has to be treated separately. In general, because the original substrate is not necessarily dense, it may cause the wallpaper to be affixed and fall off, etc.. Placing the wallpaper directly on the original wallpaper will have a greater risk. All the original wallpapers need to be erased and the above The method of detecting the paint substrate was examined on the substrate to see if it was necessary to further eradicate the putty layer, and the subsequent work was consistent with the “Old House Paint Needs First Testâ€. Of course there are exceptions, if the original paving is a wallpaper of special purity, such as high-purity wood pulp wallpaper, soak the wet towel on the wallpaper, more than 10 minutes later, to see if there is empty drum phenomenon. If there is still no emptying, you can directly paste any wallpaper on it. If there is empty drum, you need to remove all the wallpaper and carry out the next step of substrate inspection and processing. Plaster base note crack prevention If the original base of the wall is a gypsum board, care must be taken to protect it from moisture. The first step is to place all the self-tapping screws on anti-rust paint to prevent rust from corroding the wallpaper; then, the joints of the gypsum board shall be filled with white latex and gypsum powder to prevent the plaster from cracking. Experts emphasize that gypsum powder is used instead of putty because gypsum powder and gypsum belong to the same material, and the expansion and contraction coefficient are the same. If putty is used, the shrinkage factor is different, and cracking may also occur. In order to ensure that no cracks appear, it is also necessary to apply a bandage to the joints after the gypsum powder is dried. In general, there are currently gauze cloths, kraft paper, and grids. Due to the large gauze gaps in the mesh and weak adhesion, it is rarely used at present. After the patching, the sanding and scraping work is performed again, and then the wallpaper is normally laid again. Wooden substrate to prevent deformation What should I do if I need to apply wallpaper on wooden boards? First of all, a thin layer of paint should be applied to the wooden plates to prevent the wood from being deformed by moisture. Where cracks are present, make-up stitches are made using putty instead of gypsum powder. "Because of the high hardness and stability of the putty, there is no problem of shrinkage and expansion." The next step is to brush putty. Prepare putty with a 1:1 ratio of white latex and water and apply a thin layer. "To be as thin as paper, in fact, it is to play a role in filling up the unevenness of the wooden board." The putty layer also needs to be able to stick to wooden boards, and if it is not strong, it will easily cause the wallpaper to fall off. After polishing with sandpaper, a thin layer of paint (either solvent-based or water-based paint) can be used to prevent the wood from deforming and causing problems with the wallpaper. After these tasks are done, normal wallpaper paving can be performed. The base must meet 7 requirements Experts said that regardless of the substrate material, if you want to wallpaper wallpaper, you generally need to meet the following seven criteria: 1. smooth. You can use a 2 meter ruler, or use a flashlight to illuminate the wall, and follow the light, if there is no obvious unevenness. 2. Have a certain carrying capacity. Here, you can put on your fingernail to putty, if you can't get it down, or use a sticker to put it on the putty layer. If you remove the tape without scratching the putty, it means that the putty has a certain carrying capacity and is qualified. 3. Water absorption is reasonable. Splash on the wall with water. If the wall gets wet, between the splash of water on the glass and the splash of water on the sponge, it can be done. 4. PH value is neutral. Using pH test paper, it can be neutral. 5. The surface should be clean and the colors should be the same. 6. smooth. Regarding the smoothness, different wallpaper products have different requirements, but need to meet the requirements of various wallpapers. 7. dry. In general, the moisture content of wooden boards must not exceed 8%, and the moisture content of walls must not exceed 12%.
