Before proceeding with the direct preparation of the surface for wallpapering, you need to purchase them and select the appropriate adhesive composition for them. If you choose the wrong glue for wallpaper, then often, after a certain time, this leads to lagging of the paintings, as well as to the appearance of an unpleasant smell in them.
Today's market offers a wide
selection of wallpapers, there are even such types that are produced with adhesive already applied to them. To activate this layer, you just need to moisten the base with water. But still, most of the wallpaper, as before, is fixed in a simple way - with glue.
There is a large selection of adhesive compositions for various types of wallpapers, but not all of them meet all the desired advantages: one type is environmentally friendly, but practically does not hold the canvas, the other sticks so that it is simply impossible to tear it off, but has a dubious composition.
Wallpaper glue can be divided into two types - universal and special. The first is intended for gluing walls with any kind of wallpaper, the second is used for products that have a vinyl coating. The instructions for use, which is applied to the package, indicate for which wallpaper it is intended, they can be light or heavy. The term "lungs" refers to their paper variety. “Heavy” - all the rest (acrylic, vinyl, textile, etc.).
High-quality glue for wallpaper, with its proper selection and use, firmly holds the canvas on the wall for five years. An indicator of quality is that when the glued canvases are torn off, they will tear on the paper, not on the seam.
When deciding which glue for wallpaper is better, you need to consider some initial data. Namely, what material the wallpaper and the wall are made of, what weight the wallpaper has, as well as critical glue indicators. An important factor is the humidity and temperature in the room.
Thin, lightweight paper wallpapers are glued using conventional CMC (carboxymethyl cellulose) glue. For this type of canvas this is the most suitable and fairly high-quality option. The acquisition of an expensive adhesive would be a waste of money. For a duplex, which has a high paper density, it is better to use universal glue, which is slightly more expensive but has higher adhesive ability.
Vinyl or jute wallpapers are attached to a special glue; in addition to the basic components, it also includes fungicidal additives that prevent mold from forming under the product. Of course, you can glue this wallpaper with the use of universal compounds, but then you will need to prepare a solution with a higher concentration, which will lead to an increase in the consumption of dry matter.
Adhesive for wallpaper on a non-woven basis also belongs to the category of special. A feature of its application is that it is applied directly to the surface of the wall, which can significantly reduce its consumption.
Wallpaper glue, which includes antiseptics, is recommended for use on unheated surfaces (external walls), since these additives prevent the formation of bacteria, mold and fungus under the products.
