Wall paper or wallpaper (in English: Wallpaper) is a decorative covering that is used to cover the surfaces of internal walls in offices, houses and other buildings; Wallpaper is one of the aspects of interior design. This type of covering is mostly sold in rolls or by the meter and is used by sticking it on the wall. Wallpapers can be plain (painted) or woven (like Anglipta) or made with graphic patterns. Wall paper printing methods include surface printing, engraving printing, silk screen printing, digital printing or printing by rotary printing machine.
Vinyl -coated paper
This wallpaper has a paper material on which a patterned surface is sprayed or coated with a sample of acrylic vinyl or polyvinyl chloride (PVC). This sample of papers is classified in the category of washable and anti-stain papers and can be used for most spaces. This sample is much more resistant to grease and moisture than its simple sample and is even suitable for use in kitchens.
Fabric coating
This wallpaper has a light vinyl material of acrylic or liquid vinyl. Its patterned layer is printed on this cover. Generally, this paper is lighter and suitable for use in spaces with less humidity such as living room.
Paper with hard and solid vinyl
This type of wallpaper consists of a laminated paper layer covered by a solid vinyl coating. These paper samples are completely resistant since their patterned surface has a very strong vinyl coating. These papers are classified as washable and peelable papers. Solid or hard vinyl coated paper can be used in many home environments that may get moisture, grease and stains. But they are not suitable for use in workshops and warehouses and environments where physical contact with paper occurs.
Installation of wall paper
Just as the wall needs to be prepared before painting, the wall must be prepared first to install wallpaper. Wall preparation, known as underlaying, involves removing holes and cracks in the plaster of the wall so that the wall is perfectly smooth and even. In addition, the material of the wall is not suitable for sticking wallpaper. For example, plaster walls are better accepted for wallpaper than cement or wooden walls. Wallpaper has its own use. For example, if it is used in the bathroom, even if the wallpaper is anti-moisture, after a short time due to the humidity of the environment, the glue under the wallpaper will be lost and it will be damaged very soon. It is better to use wallpaper in a dry environment. Another point that should be taken care of before installing wallpaper is the dimensions of the wall. If the length and height of the wall is small, many of the patterns on the wall paper will be cut and its design will not be shown well. The design of wallpapers is repetitive, except for poster wallpapers; Therefore, it is better to choose a wall that has enough space to repeat the wallpaper design several times. The larger the wallpaper design, the larger the wall it will be installed on. In addition to the wall and ceiling, which are the usual uses of wallpaper, wallpaper can be installed inside the closet, library, and on the window frame.
