Many people did their own wall paperingapartments or houses and faced not only the problem of choosing the type of finishing, but also the search for an answer to the question: what glue to use to glue the wallpaper? This problem is made easier by the fact that the glue is usually selected for the already purchased canvases.
Wallpaper gluing scheme.Basically, any type of wallpaper can be glued with almost any adhesive material to any surface. It's all about the rationality of the composition used. For example, using epoxy resin-based formulations to , would be an overkill. The connection will be reliable, and subsequently such wallpaper can only be torn off the wall with a hammer and chisel.
Classification of wallpaper paste
Wallpaper glue entering the retail network,is a powder, granules or small chips. Sometimes there are ready-made solutions, which are acrylic or latex dispersion. In general, all these materials are divided into two groups according to their functional purpose with a certain degree of tolerance: universal and specialized.
Wallpaper glue consumption table.Universal compositions include those that can be used for all types of wallpaper materials (from paper wallpapering to fiberglass). A feature of the composition that provides a wide range of applications is the presence of carboxymethyl cellulose. The inclusion of this substance in the composition allows you to obtain solutions with the required characteristics of viscosity, fluidity, and adhesive ability. The properties are adjusted by the ratio of the original dry substance and the added water. The principle of preparing the adhesive solution in this case is as follows: the more powder is dissolved in water, the thicker (heavier) the adhesive can withstand. Among the universal adhesives that allow you to glue paper wallpaper, vinyl or non-woven, there are also ready-made compositions, the most striking representative of which is Bustilat glue, which is a latex dispersion that includes fungicides and carboxymethyl cellulose. Specialized adhesives are compositions that, with the help of various chemical additives, are intended for gluing specific types of wallpaper:

As a rule, the name of the glue immediately indicates the type of wallpaper for which it is intended. Adhesives prepared on the basis of starch, pastes, stand apart. Most often, these compounds are used when deciding whether to . Thus, paste can be classified as a specialized glue. Return to contents</a>
Selecting an adhesive
Influence on the choice of one or another type of gluehave such operational characteristics of the room as temperature and humidity conditions. An important factor is also the purpose of the room where they are going to be used. In residential premises, it is unacceptable to use compositions that can release toxic substances. In rooms used as children's rooms, it seems optimal to use starch-based glue with added fungicides with paper wallpaper. This combination ensures the efficiency of the technological process of gluing wallpaper and the safety of the resulting coating. In rooms characterized by temperature and humidity changes, such as a loggia, kitchen, wallpaper and the glue with which they are glued must correspond to the operating mode. In this case, the corresponding ready-made compositions are well suited. Return to contents</a>
Preparing the wallpaper for work
Scheme for applying glue to wallpaper.The process of preparing the adhesive solution for work does not present any difficulties. With ready-made compositions, everything is clear and simple: just open a container with wallpaper glue and apply it to a sheet of wallpaper or to the wall surface using a brush or roller. With adhesives produced in powder form, the situation is more complicated: here you need to prepare a working solution. The conditions for preparation and dosage of reagents for preparing solutions for a specific type of wallpaper are usually indicated by the manufacturer on the packaging. In general, the sequence of actions will look like this:
The viability of the finished solution in a tightlyclosed container can be stored for a week. Sometimes the manufacturer indicates the possibility of additional dilution with water of a slightly solidified solution that has begun to lose fluidity. An important condition for obtaining a high-quality solution is the use of unexpired source material. Carboxymethyl cellulose is white, so if, upon opening the package, granules and shavings of a yellowish or cream color are found, this is evidence of expiration of the shelf life or violations in the production and storage technology. Adhesive solution, of course, can be made from such raw materials, but its quality can already be significantly worse. To ensure the required adhesive capacity, the consumption of glue from the package will increase significantly. Today, special coloring additives are very often introduced into the recipe for adhesive mass, which facilitate the process of monitoring the coating of work surfaces with glue. So in this case, a non-white color of the package contents will no longer be a sign of a defective or expired composition. The process of preparing an adhesive solution based on modified starch is practically no different from the preparation of solutions based on carboxymethyl cellulose. The viability of these compositions is almost the same. It’s a different matter if the paste is cooked using natural starch:

Correction of glue defects
The main disadvantage of the paste is its lowresistance to biological damage and moisture. To correct this drawback, you can add some antiseptics to the starch. To increase the adhesive capacity, it is recommended to add a small amount of PVA glue. The correct choice of what glue to use to glue the wallpaper, proper preparation and application of the adhesive composition will allow you to get a high-quality and safe wall covering. The quality of the work done can be judged by such a factor as invisibility. In other words, high-quality glue should not remind of its existence with obsessive odors, visible stains and peeling paper wallpaper.
