Throughout the development history of the wall, it has generally experienced such periods as the earth cement wall era, the white ash period, the melamine period, the latex paint period, the wallpaper period and the ecological wall material era.
In the era when materials are relatively backward, there are no more choices for wall decorations. Cement and soil are the first steps for humans to explore wall decorations. Later, people put white ash on the walls to make the room clean and bright, but soon It was found that the white ash gives a very rough visual impression and is easy to fall off the powder, often staining the clothes. Then the imitation porcelain came into being. The imitation porcelain is smooth and delicate, but it is not resistant to water, and it is easy to foam and yellow after moisture.
Latex paint is a successful breakthrough in the exploration of wall decorations. It is very convenient to use and makes the room spacious and bright. However, the artistic effect is also very simple, unable to meet people's requirements for individual decoration. With the subdivision of the decoration style, the wall material with artistic expression has become a new direction for people to pursue, so the wallpaper has entered the consumer's vision.
After decades of development, the domestic interior wall decoration materials market has basically formed a pattern that is dominated by paints and wallpapers, and new materials such as diatom mud and wallpaper paint. From the performance point of view, the mainstream products paint and wallpaper in the end which is better? We will carry out PK from the five perspectives of price, environmental protection, effect, construction and life.
First, the price
In terms of price, the price of a roll of mid-range wallpaper is about 160-300 yuan, and the wall of 5 square meters is decorated according to small rolls of wallpaper. The total cost of a house of 100 square meters is more than 8,000 yuan. The use of mid-range latex paint (including accessories and labor costs) for a 100 square meter house will not exceed 5,000 yuan. The decoration of the same grade, the cost of wallpaper is obviously more expensive than latex paint.
Second, environmental protection
Brands and high-quality wallpapers and coatings generally meet environmental requirements. High-grade wallpapers generally have outstanding environmental performance; interior wall coatings are mainly latex paints, which are water-soluble paints, and can basically meet safety standards.
Low-end wallpapers and paints often have security risks. Such as low-grade PVC wallpaper contains a large amount of formaldehyde, and due to poor gas permeability, formaldehyde is not easy to release, the wall moisture is not easy to evaporate; low-grade coatings in addition to formaldehyde may exceed the standard, the harmful substances such as benzene, lead, mercury, etc. will also harm the residence The health of the person.
Third, the effect
Although many brands of paints are now more and more powerful, and the colors are more and more diverse, they are still monotonous compared to the wallpapers with colors and patterns. Compared with paint, wallpaper has more texture, rich colors, diverse patterns, three-dimensional, style can be gorgeous, elegant, classical, fashion, etc., can present the most intuitive visual effects, more reflect the owner's taste and emotional elements.
Fourth, construction
From the difficulty of the two construction difficulties, the coating is relatively easy. If the construction cycle is taken into account, the cycle of the paint will be longer.
The technical requirements of the construction of the wallpaper are high, too much glue is applied to cause overflow, or the waterproof treatment of the wall is not in place, which will affect the aesthetics of the wallpaper. The use of paint decoration, the construction difficulty is relatively small, just ensure that the putty is evenly coated, the base layer is cleaned and the coating is too thick.
In terms of construction period, you can choose wallpaper decoration, just apply a layer of varnish or wallpaper base film on the polished wall. You can use the paint decoration. The wall must be constructed at least three to five times, one day at a time. It takes a week, and it is generally necessary to maintain indoor ventilation for more than 10 days before check-in.
Five, life
In general, the life of a pure wallpaper is about 8-10 years, PVC wallpaper is about 5-8 years, metal wallpaper is about 3-4 years, and the life of latex paint is about 5-10 years. In addition, differences in brand, material and construction techniques can also affect the useful life of the product.
