When can I make an appointment to arrange the construction of wallpapers during the decoration process? Can the walls painted with emulsion paint be directly pasted with wallpapers? Why does the salesperson say that the color difference of some wallpapers is not a quality problem? Why do some wallpapers

1. Is it better to use varnish or base film for wall treatment before laying wallpapers

is OK. The traditional method is to use varnish, which performs well in physical and chemical properties. In recent years, the water-based wallpaper film that has appeared on the market is more environmentally friendly, and customers can choose it according to their personal preferences

2. When can I make an appointment to arrange the construction of wallpaper during the decoration process

procedures that must be done well: wall treatment, door jambs, window jambs, wood murals, skirting lines, ceilings, air-conditioning hanging plates, and the construction of reserved holes (radiator holes, curtain bar holes, air-conditioning holes, etc.). Procedures not to be done: lamps, switch panels and radiators should not be installed as far as possible, but should be removed in principle. Confirm the construction time a few days in advance

3. Can the wall surface painted with emulsion paint be directly pasted with wallpaper

this is not recommended. If the wall has been painted, the original paint must be removed, and the varnish (or base film) must be painted after the base course is reprocessed. If the walls that have been painted with emulsion paint are not eradicated and directly puttying or varnished, the paving may cause the adhesive strength of the base course and lead to the glue opening of the wallpaper, which is not warranted

4. Preparation method of wallpaper adhesive powder

1 The dilution ratio of wallpaper adhesive powder and water is about 1:5~1:8

2. For lighter and thinner wallpapers, the dilution ratio of glue powder and water is 1:8. For special wallpapers and heavier wallpapers, the dilution ratio is 1:5

3. Put the water into the container, and then pour into the rubber powder to stir. In spring/summer/autumn, stir continuously for 10 minutes and in winter for 15 minutes

4. Place it for 15 minutes, stir it for about 10 minutes, and then use it after confirming that the rubber powder is completely dissolved

5.1 box (200g) of wallpaper adhesive powder can be constructed for 15-20 square meters, that is, about 3-4 rolls of small rolls of wallpaper

5. Why do salespeople say that the color difference of some wallpapers is not a quality problem

if the material is cloth, cloth base, cloth paddle fiber, flocking, diatomite, wood paddle fiber, gold silver platinum, metal wire, mica sheet and other Wallpapers made of natural materials, due to the characteristics of the material, natural color difference may occur, and the different textures may also produce relatively obvious seams, which is generally not a quality problem, It is normal. In addition, the batch number, printing and dyeing and time of wallpaper may cause differences in color, and the difference in observation light and angle will also cause sensory differences

6. Why are some wallpapers easy to fade after wiping with a wet cloth

the ink used in wallpaper printing with water-based ink is mainly water-based ink. Compared with other printing inks, water-based inks do not contain toxic and harmful volatile organic solvents and heavy metals, so they are not harmful to the health of printer operators, will not pollute the atmospheric environment, and will not pollute the print itself. However, it is precisely because of the characteristics of water-based ink decomposition in the presence of water that the wallpaper surface may fade after wiping with a wet cloth, especially for wallpapers made of pure paper, wood pulp fiber and other natural materials, it is absolutely not allowed to wipe with a wet cloth. With people's increasingly high pursuit of environmental protection, water-based inks are being more and more widely used

7. Why can't some wallpapers directly face the flowers

this kind of situation rarely occurs, and more often it is a wide wallpaper with protective edges. When paving, the protective edges need to be cut off, and the process of "edge stitching and tailoring" must be used during construction. If you still have questions about technology, you can call the dealer for consultation

8. What should I do if I find something wrong with the wallpaper

1. Please stop immediately and do not continue the construction

2. Please keep the label and sample

3. Please contact the sales hall immediately

4. Try to provide photos

9. Wallpaper is not suitable for areas with wet weather. It is afraid of moisture and water, and it will mildew, right

No. Who said that wallpaper would not be used in the humid island countries of Japan, Hong Kong, Singapore, Malaysia and other southern regions? For the most widely used PVC (including PE) adhesive wallpaper, as long as the wall is dry during construction, the wallpaper can be stuck firmly on the wall. Because the surface of the wallpaper is made of adhesive material, it is naturally water-resistant and waterproof, while the paper on the back of the wallpaper is sealed in the wall by glue, and it can't contact the water in the air (unless the water comes from the inside of the wall), or the water used during cleaning, it will never get moldy under normal circumstances

10. Some people say that cloth (including non-woven) based wallpaper is better and higher grade than paper-based wallpaper. Is this statement correct

is not only incorrect, but also highly misleading, causing people to distort and paranoid understanding. This kind of statement came out of manufacturing and sales surprises and traps

what is the high-end embodiment of wallpaper products? The level of surface material modeling technology, and the taste design of pattern and color. Bucky is the base material. The underlying material has nothing to do with the pattern, shape and color taste. Where is Bucky better? It is stronger and more resistant to impact and tear than paper base. It is suitable for public areas with defective walls (soft surface, easy to crack) and vulnerable to impact. The Buji concept itself is not only irrelevant to high-end (taste), but also basically not adopted in Europe because it is integrated with the rubber surface and does not have the important construction performance of "delamination stripping and tearing"

11. Is it correct to say that pure paper wallpaper is environmentally friendly and PVC adhesive wallpaper is not environmentally friendly

is not only incorrect, but also highly misleading, causing people to distort and paranoid understanding

is pure paper necessarily environmentally friendly? No. Among the three environmental protection indicators (formaldehyde, vinyl chloride monomer and heavy metals) required by the national standard to detect wallpaper products, formaldehyde is targeted at paper. The content of vinyl chloride monomer is for PVC materials, and the content of heavy metals is for pigment inks

people with industry common sense should understand that modern wallpaper originated in Europe (Western Europe and Britain), thanks to the invention of plastic. The wallpaper with polyvinyl chloride (PVC) as the fabric was successfully developed in 1961, opening a new chapter for human beings to decorate their homes with wallpaper. Western Europe and even the United States, Canada, Russia, Japan, South Korea and other developed countries have produced and used PVC adhesive wallpaper for more than or nearly half a century. As for pure paper wallpapers, they are only used in very few regions in the world, that is, only four Nordic countries (Finland, Sweden, Norway, Denmark) use them. They are simply because of their sparse population and rich natural resources, and they are committed to environmental protection. In Western Europe, Eastern Europe and other developed countries using wallpaper, there is basically no market for pure paper wallpaper. The reason is very simple. Pure paper wallpaper does not have any practical functions: construction is difficult, it becomes damp in case of water (the surface is not waterproof), it is easy to get dirty, dirty can not be cleaned, it is easy to damage without strength, and it is not flame retardant. Note that if the surface of pure paper wallpaper can be waterproof, it can no longer be confused with pure paper, because its surface has been treated with chemical resin polyethylene (PE) or other resins for surface waterproof coating. (PE film has good air permeability and high transparency. Because the ratio of carbon to hydrogen in the molecular structure is 1:2, there is no black smoke when burning.)
