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 wallpaper glue, then often, after a certain time, this leads to a backlog of paintings, as well as an unpleasant smell.
Today's market has a large selection of wallpapers, there are even types that are produced with an adhesive composition already applied to them. To activate this layer, you just need to moisten the base with water. But still, most wallpapers, as before, are attached in a simple way - with glue.
There is a large selection of adhesive compositions for various types of wallpaper, 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.
There are two types of wallpaper glue - universal and special. The first is intended for pasting walls with any kind of wallpaper, the second is used for products that have vinylcoating. The instructions for use, which is printed on the package, indicate which wallpaper it is intended for, they can be light or heavy. The term "light" refers to their paper varieties. "Heavy" - all the rest (acrylic, vinyl, textile, etc.).
Quality wallpaper adhesive, with proper selection and use, firmly holds the canvas on the wall for five years. An indicator of quality is that when the glued sheets are torn off, they will tear along the paper, and not along the seam.
When deciding which wallpaper glue is best, you need to take into account some initial data. Namely, what material the wallpaper and the wall are made of, what weight the wallpaper has, as well as the critical indicators of the glue. An important factor is the humidity and temperature in the room.
Thin, lightweight paper wallpapers are glued with ordinary 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 composition will simply be a waste of money. For duplex, which has a higher paper weight, it is better to use an all-purpose adhesive, which is slightly more expensive but has a higher adhesive power.
Vinyl or jute wallpapers are attached to a special glue, in addition to the basic components, it also contains fungicidal additives that prevent the formation of mold under the product. Of course, you can glue thesewallpaper and using universal compounds, but then you will need to prepare a solution with a higher concentration, which will lead to an increase in dry matter consumption.
Glue for non-woven wallpaper also belongs to the category of special. A feature of its use is that it is applied directly to the surface of the wall, which can significantly reduce its consumption.
Wallpaper adhesive containing antiseptics is recommended for use on unheated surfaces (external walls), as these additives prevent the formation of bacteria, mold and fungus under products.
