Wallpaper CMC-glue

One of the oldest and most reliable wallpaper adhesives is carboxymethyl cellulose (CMC). The fact is that carboxymethyl cellulose does not have a coagulation temperature, i.e., when dissolved in hot water, it does not form precipitates and lumps. Simply put, in the preparation of glue based on this substance, the temperature of the water does not play a strong role. It is not easy to understand the CMC adhesives on the market, their range is constantly replenished and changed. Therefore, in order not to fall for the bait of bunglers and not to purchase low-quality goods, we recommend that you adhere to a few simple rules. First and foremost, CMC glue is a white powder. If so, then it will glue everything perfectly, quickly dissolve in water, without forming lumps.


If the glue you are buying is yellow and instead of powder in the package there are chips, then this is a clear sign that the product is of poor quality. This is especially dangerous for paper wallpapers, such glue can easily seep through them and spoil the appearance with its yellowness, moreover, it dissolves in water for a long time and poorly. It is not recommended to use domestic adhesives for imported wallpaper, since the results can be unpredictable, there have been cases when they changed color, spoiling the color gamut of the wallpaper. All mistakes in choosing can be avoided if you buy glue of well-known brands, such as: "Quelyd" (France), "Dufa Tapetenkleister" (Germany), "TD 2000" (England), "Papa" (Germany) or use one and of the same brand as the wallpaper.

Adhesives based on carboxymethyl cellulose differ not only in quality, but also in purpose. There are CMC adhesives for light, medium and heavy wallpapers. Their main difference from each other is the concentration of carboxymethyl cellulose. The higher it is, the higher the viscosity of this glue. This is especially important for working with heavy wallpaper, the glue with low viscosity will not grip them with the necessary strength and they may come off. Therefore, you need to follow the rule: the thicker the wallpaper, the thicker the glue should be.


For rooms with high air humidity, CMC glue with antiseptic substances added to it is perfect, this will prevent the decay process.

Another type of wallpaper adhesives is vinyl glue. It is ideal for gluing vinyl, foam, fabric or embossed wallpapers. In addition, it is very convenient to work with it, wallpaper on freshly applied vinyl glue glides well over the surface and therefore it is easy to align and dock. If necessary, the wallpaper can be torn off (if the glue has not yet dried) and glued again without adding glue.

The technology for dissolving dry wallpaper adhesives is the same. Water at a temperature of 25 degrees is poured into an enameled or plastic bucket, then a whirlpool is created in the container, into which, without ceasing to stir, the dry mixture is poured. Until fully cooked, the glue should stand from 3 minutes to several hours, the time is always indicated on the package.

There are several ways to apply glue to a surface. It can be spread on the canvas and immediately glued, this is usually used when gluing light paper wallpaper. Or the second option: glue is applied to the surface, then it is allowed to soak into the base and then another layer is spread. Only after that the wallpaper is glued. As a rule, the procedure for working with wallpaper is described on their packaging or in the attached instructions.


Dispersion glue is also used for gluing velor, textile, vinyl or glass wallpaper. It differs from other varieties of wallpaper adhesives in its increased strength, the wallpaper glued to it is not so easy to tear off the wall. Another advantage of dispersion adhesive is that it is moisture resistant and can withstand high humidity. However, it should be noted that using it in the bathroom is still not recommended.

Dispersion glue, unlike ordinary dry glue, is released ready for use, and it is applied immediately to the surface to be trimmed, and not to the wallpaper itself. This glue dries for about 12 hours.

Liquid Nails

This name was given to an adhesive based on an aqueous dispersion of acrylic copolymers, which was specially developed for quick and easy installation without the use of nails. On "liquid nails" you can glue finishing materials from wood, chipboard, fiberboard, gypsum, plasterboard, cork, cardboard, up to ceramics and metal. In fact, it is a universal glue that allows you to glue finishing materials to various surfaces and glue them together.

Such glue is applied to a dry, clean, degreased surface, but not in a continuous layer, but in dots (if the material is light), or a snake (for a heavy material). Drying time for this glue is 12-24 hours, depending on the layer thickness, temperature and humidity.

Latex based adhesive

This adhesive is versatile and is used for almost all types of interior work. They are glued to parquet, linoleum, ceramic and tile and many other materials on almost all bases. The method of application is traditional: the surface needs to be cleaned of dirt, degreased and applied with a thin layer of glue, then almost any material can be attached to the glue. The setting time for the glue is from 30 minutes to an hour.

How can you glue ceramic tiles?

Ceramic tiles can be glued to the surface using ordinary cement mortar, cement-based adhesive mortar, or special mastic. Cement-based glue is much cheaper than mastic, therefore it is used more often in work. It is used for fastening tiles, ceramic tiles, slabs made of natural or artificial stone, large sizes and with a strongly pronounced relief of the back side of the tile.


First, the first thin layer of glue is applied to the prepared surface and smoothed, then another layer is applied, on which the tiles are actually laid. This "patty" is made in order to provide maximum adhesion to the surface. The glue dries up in a day, and after two more it acquires maximum strength.

Sodium silicate mastic is applied to the surface in a slightly different way. It is placed on a flat surface in one thin layer, 0.5-1 mm thick, on an uneven surface, the mastic is laid with a layer necessary to level the surface, after which the tiles are laid. The mastic hardens after 3 hours, and finally dries up after 5-6 days.


PVA glue

During repair and construction work, it is sometimes necessary to glue the wood. For this purpose, an adhesive based on an aqueous dispersion of polyvinyl acetate (PVA) is best suited. He glues any tree almost "tightly". It is able to withstand a burst pressure of about 100 kilograms per square meter. cm.

PVA adhesives are available in several types.

"PVA-P" is universal, it can glue veneer, plywood, chipboard, fiberboard, just pieces of wood.

PVA-M specializes in wood, veneer and chipboard.

"PVA-T" not only glues wood, but is also used for adding to cement mortars, as it provides better adhesion to the surface. Such glue dries quickly, in one and a half to two hours.

Of course, this is not a complete list of all adhesives used in construction. Full information can be obtained from the specialists who are in any good repair and construction company.
