Autumn decoration face is very important, wallpape

  • Detail

It is high and crisp autumn now. Because the temperature and humidity are appropriate, the impact of high temperature and humidity in summer and low temperature in winter on building materials can be avoided, so autumn is also a good season for decoration throughout the year. But the choice of materials for autumn decoration is very important, especially the choice of wallpaper and paint. What problems do you need to pay attention to? Let's have a look

good wallpaper depends on whether it can be wiped with a wet rag

today's home environment is becoming more and more themed, with several walls or even just one wall. Using the texture and texture brought by wallpaper, coupled with appropriate furniture and accessories, you can create your favorite atmosphere

there are many kinds of wallpapers. At present, the most popular wallpapers in the world are adhesive based wallpapers, textile wallpapers, natural material wallpapers, plastic wallpapers, glass fiber wallpapers, metal wallpapers, fluorescent wallpapers, etc. When choosing wallpaper for home decoration, we mainly choose patterns and colors, and make choices according to the room environment and purpose, but we must not ignore health and environmental protection issues

wallpaper can generally be used for 10 years.

wallpaper is the most environmentally friendly material among decoration materials. It is not only harmless to human body in use, but also does not pollute the environment in the production process from raw materials to finished products. Wallpaper adhesive is also very environmentally friendly. It is made of grain starch

when choosing wallpaper, we should first consider the area, spatial scale and orientation of the room. In principle, wallpaper is suitable for posting in any room, from the living room to the bedroom to the kitchen. Secondly, the advantage of wallpaper is that you can decorate the room with different wallpapers, and you can easily distinguish the functions of the room

it is easy to use, durable, erasable and washable, and easy to replace. Generally, there is no problem after 10 years of normal use. Slight stains can be wiped off with a wet rag, and serious ones such as lampblack, color, food residue, pen graffiti can be wiped off with a rag or toothbrush dipped in household detergent

wallpapers are divided into paper wallpapers, PVC wallpapers, foaming wallpapers, non-woven wallpapers, fabric wallpapers, cloth wallpapers, gold foil wallpapers and special Wallpapers according to the different substrates

there are many specifications of wallpapers. At present, there are two common types in the market: 0.53 meters × 10.05m and 0.70M × 10.05 meters. Among them, 0.53 m × There are many options for 10.05 meters

it is best to choose natural fiber wallpaper or full paper wallpaper

there are many factors that need to be considered in the selection of wallpaper, which can be selected according to the decoration style, or can be comprehensively considered according to the material characteristics, room size, function or orientation, but when using, we must pay attention to coordination, especially in the selection and collocation of colors and patterns, we need to follow certain principles

1. Whether you choose wallpaper or wallpaper, you should mainly consider three aspects: fire resistance, color, and cleaning difficulty. In recent years, there are not a few wallpapers and wallcoverings added with fire-proof materials, and others added insect proof, mildew proof and sound-absorbing materials, which are undoubtedly very important for consumers who want to improve the quality of their homes

2. The wall is the space with the largest area of decorative materials in the bedroom. Therefore, the color system and patterns of wallpaper are the main direction of choice. Harmonious tones can convey the overall beauty, and the collocation of bright contrast will make the space lively and change

3. Whether it is easy to clean is another consideration when choosing wallpaper. The easy cleaning characteristics of wallpaper include dust prevention and water resistance. For example, users are more concerned about whether they can directly wipe the stains on the surface of the wallpaper with a wet rag

4. When choosing wallpaper, we must see whether it meets the standard of "limit of harmful substances in wallpaper of interior decoration materials". It is best to choose natural fiber wallpaper or full paper wallpaper; We should also consider the environmental protection performance of wallpaper adhesives and choose famous brand adhesives with guaranteed reputation, preferably water-based ones; Before pasting the wallpaper, the paint should also meet the environmental protection standards

in the impression of many people, wallpaper is easier to lay than paint. It's OK to keep the wall flat and clean, but it's not. It is understood that the laying of wallpaper has a lot to do with the substrate. Different substrates need to be treated differently, and many details need to be paid attention to in the treatment. Do you want to paste wallpaper? It may not be as easy as you think

compared with paint, wallpaper paving is simpler

don't paint the wall of a new house

for wallpaper, if the paving materials are different, the treatment methods to be taken are also different. If wallpaper is laid on the wall of the new house, the base treatment is the simplest. The procedure is the same as that of the foundation wall construction, except that the paint is not applied, that is, the interface agent is normally applied on the plastering layer, and then the putty is applied for 2-3 times. Then you can decorate other Tilers, oilers, etc. and lay wallpaper on the wall when it is finished

the paint of the old house needs to be tested first

if the original wall is painted with paint and you want to renovate the wall, is it OK to directly lay wallpaper on it? In response to this problem, experts said that if it is the wall of an old house, some judgment is needed. If the original coating is relatively tight and does not fall off, you can directly brush the base film on it (the necessary material for pasting wallpaper, which can firm the wall, increase the adhesion of wallpaper, and protect the wall when dismantling), and directly lay the wallpaper. However, if the original coating is unstable, the original substrate needs to be removed

there are also six important things to know about wallpaper

how to determine whether the original paint needs to be eradicated? The owner can test the paint by himself. Take a wet towel dipped in water (it's better not to bubble the floor), fix it on the wall in some way, and check it the next morning. If there is no peeling and falling off on the wall, it means that the wall base is well treated, and the combination is still very tight. You can directly brush the base film on it and pave any wallpaper. If the wall surface bubbles and falls off, it indicates that the wall base is unstable. If the wallpaper is directly paved at this time, the wall adhesion is relatively low, and the wallpaper is easy to fall off. If all the walls are unstable, it is necessary to uproot all the walls, Shovel them to the plastering layer, brush the interface agent again, and apply putty

if only part of the wall base is unstable, it is only necessary to remove part of the base, re brush the interface agent and apply putty. After completing this part of the process, the whole wall should be marked out with a wallpaper knife. Generally speaking, the deeper the scratch is, the denser the small square is, the better& ldquo; Because the original base is relatively smooth and the adhesion is relatively poor, this method can connect the front and rear putty, ensure the stability of the base and reduce the possibility of wallpaper cracking& rdquo;

empty old wallpaper should be eradicated

what should be done if the original wall is paved with wallpaper? Can I put a new wallpaper directly on the original wallpaper? Experts said that this should also be treated separately according to the situation. Generally speaking, because the original base is not necessarily dense, it may cause the wallpaper to fall off after paving, and there is a great risk of directly paving the wallpaper on the original wallpaper. It is necessary to remove all the original wallpaper, and use the above-mentioned method of detecting the coating base to check the base to see whether it is necessary to further remove the putty layer, and then the work will be the same as “ Old house paint needs to be tested first ” Is consistent

of course, there are exceptions. If the original wallpaper is of special purity, such as the wallpaper of high-purity wood pulp, soak a wet towel in water and put it on the wallpaper. After more than ten minutes, check whether there is hollowing. If there is still no hollowing, you can directly lay any wallpaper on it. If there is an empty drum, you need to remove all the wallpaper and carry out the next step of substrate inspection and treatment

pay attention to crack prevention of gypsum base

if the base of the original wall is gypsum board, you need to pay attention to moisture-proof treatment. The first step is to apply antirust paint on all self tapping screws to prevent rust from corroding the wallpaper; Then, the joints of the gypsum board are filled with white latex and gypsum powder to prevent cracks caused by gypsum shrinkage. Experts emphasize that gypsum powder is used here instead of putty, because gypsum powder and gypsum are of the same material and have the same expansion and contraction coefficient. If putty is used, different contraction coefficient will also lead to cracking

in order to ensure no cracks, it is also necessary to stick bandages on the joints after the gypsum powder is dry. Generally speaking, there are dacron cloth, kraft paper and mesh gauze at present. Due to the large gap and weak adhesion of mesh gauze, it is rarely used at present. After the cloth is pasted, polish and scrape the putty, and then lay the wallpaper normally

beware of deformation on the wooden base

what should I do if I need to lay wallpaper on the wooden board? First of all, you need to brush a thin layer of paint on the wooden plate to prevent the wood from being damp and deformed. Where there is a gap, use atomic ash instead of gypsum powder to fill the gap& ldquo; Because atomic ash has high hardness and strong stability, there is no problem of shrinkage and expansion& rdquo;

the next step is to apply putty. Make putty with white emulsion and water in the ratio of 1:1, and brush a thin layer& ldquo; To be as thin as paper is actually to flatten the uneven parts of the wooden board& rdquo; The putty layer also needs to be able to stick to the wooden plate, which is easy to cause the wallpaper to fall off if it is not strong. After sanding with sandpaper, apply a thin coat of paint (solvent or water-based paint can be used) to prevent wood deformation from causing problems with the wallpaper. After finishing these works, you can carry out the normal wallpaper laying work

the substrate needs to meet seven requirements

experts say that no matter what the material of the substrate is, if you want to lay wallpaper, you generally need to meet the following seven standards: 1 smooth. You can use a 2-meter-long ruler, or shine a flashlight on the wall, and look along the light. If there is no obvious unevenness, you can. 2. Have certain bearing capacity. Here, you can scratch the putty with your fingernails. If you can't scratch it off; Or stick it on the putty layer with self-adhesive. If the tape is removed and the putty is not scraped off, it indicates that the putty has a certain bearing capacity and is qualified. 3. Reasonable water absorption. If water splashes on the wall, if the wall becomes wet, it is between splashing water on the glass and being sucked in when splashing water on the sponge. 4. PH value is neutral. Use pH test paper, which is neutral. 5. The surface should be clean and the color should be consistent. 6. Smooth. Different wallpaper products have different requirements for smoothness, but they need to meet the requirements of all kinds of wallpaper. 7. Dry. Generally speaking, the moisture content of wooden boards should not exceed 8%, and the moisture content of walls should not exceed 12%
