In the reviews of domestic buyers, mainly positive characteristics are noted. This composition is convenient to use, it will not drain, the seam will turn out to be reliable. However, it is difficult to wash your hands after work; in the process of gluing, it is necessary to ventilate the room.

Composition of various resins has many beneficial properties. It will not change the shade of the processed wood, has excellent adhesion, high strength and electrical insulating qualities. However, when working with adhesive, proper ventilation of the room and the use of personal protective equipment are required. When comparing 7 products, it was found which is better. The list contains 3 of them.

Application technology

Before wallpapering (no matter what kind of glue you use), the wall surface must be thoroughly cleaned (from whitewash, old wallpaper, dust, paint residues, etc.)

If there are cracks on the wall, then they should be repaired and patched.

Before use, dry adhesives are diluted with water in the proportion recommended by the manufacturer for a certain period of time (indicated on the package) and thoroughly stirred until the lumps disappear. Next, the glue is defended until the necessary swelling of the adhesive component, after which it is filtered through a regular nylon stocking to avoid undissolved lumps from falling on the wall or wallpaper. The diluted ready-to-use glue is applied to the walls and wallpaper with a wide swinging brush.

You should know that there are two types of dry adhesives:

• for gluing thin and light paper wallpaper;

• for gluing dense and heavy vinyl wallpaper.

The Russian market offers a wide range of dry adhesives from domestic manufacturers.

Wallpaper adhesives, both ready-made and dry, should be used at an air temperature not exceeding + 50 ° С, otherwise the filler water will quickly evaporate. All wallpaper adhesives are made from environmentally friendly substances.

The Russian market offers dry adhesives of the MOMENT type produced by ERA-TOSNO under a license from HENKEL (Germany), a series of GLU-TOLIN adhesives manufactured by HOECHST (Germany), CMC (Russia), etc.

After drying, the edges of the wallpaper may come off, you can glue them with PVA glue, which should be slightly diluted with water.

Synthetic based adhesives

Most artificial adhesives are based on
polymer compounds. The most popular of the synthetic solutions are
PVA-based adhesives, resinous and polyurethane compositions.

PVA based adhesives

PVA glue is made from polyvinyl acetate. Considered one of
the most environmentally friendly compositions, due to the absence of a toxic odor. Resilient
to temperature extremes, has high elasticity. Retains properties
at high humidity, remains transparent after drying.

There are two types of PVA glue - one-component and two-component.
The first option is a universal remedy and is used indoors for
internal works. The second type contains an additional component
hardener, as a result of which it can be used outdoors.

Polyurethane adhesive

Polyurethane compounds are capable of withstanding significant
dynamic load. Moisture resistant, well tolerated ultraviolet
radiation and sudden changes in temperature. The mixture can be used in difficult
weather conditions. The additive in the form of resins increases resistance to aggressive
solutions (acids, alkalis), oil products.

Provides a good connection between wood and other materials. Front
the beginning of work, the surface of the product must be cleaned of dirt and dust. V
special gloves must be used during the process, as the glue leaves stubborn
spots on the skin. Polyurethane mixtures are considered one of the most expensive.

The adhesive composition is one- and two-component. They differ
by gluing. The one-component composition is presented ready to work.
It grabs 30 minutes after application to the surface under the influence
humidity. Before using the two-component mixture, the components
must be mixed in a special container.

Difficult to bond surfaces and materials are treated with special
polyurethane hot melt adhesives. The solution dries quickly and does not
requires additional pressure. Good for gluing oily
wood. There are a large number of types of adhesives on the market.
polyurethane base, which have special properties and qualities.

Epoxy adhesive

It is a two-component formulation containing epoxy resin
and a hardener. It is a universal remedy and can be used not only
for wood, but also other materials. Possesses high strength and resistance
to moisture and oils. Does not shrink when solidified.

When diluting the glue, the recommended proportions must be observed.
If the appropriate filler and plasticizer are added to the hardener, then
you can get a composition with the desired properties. Unlike other types of mixtures,
epoxy bonding process does not require any effort to
connections of individual parts.

There are two types of epoxy that
differ in the percentage of components.

Standard glue. Complete hardening of the mixture occurs in a day, depending on the thickness of the applied layer. The mixture can be used for the manufacture and repair of large-sized products and objects experiencing heavy loads. They are also used for gluing dissimilar surfaces.

Five-minute glue. Fast-drying compound, used for gluing parts that are difficult to fix for a long time. A high proportion of hardener reduces the fixing time to 10-5 minutes. However, the strength of such a mixture may be lower than standard. Excess glue, after drying, leaves noticeable stains that are poorly stained with stain.

BF based adhesives

For bonding wood surfaces as well as wood with other
the materials used are BF-2 and BF-4 mixtures. The basis of the composition is
polyvinyl butyral, acetone or ethyl alcohol serves as a solvent.
The adhesive is a thick yellowish or reddish mass.
colors.

BF-2 is used indoors, as it is resistant to prolonged exposure to moisture. BF-4 is characterized by frost resistance and elasticity and is more suitable for outdoor use. BF series adhesives tolerate the influence of aggressive liquids and a sharp temperature drop. They have a high strength index, however, with a strong impact on the glue seam, the strength of the latter is significantly reduced.

The most common types

Many tools are suitable for a tree, which differ in several criteria. Let's take a look at the methods of using some of the most common mixtures.

PVA

A variety of such glue for wood is the most common. In addition, it holds joints very firmly with a load of approx. 60 kg per cm2. It has no shelf life and can be applied to a variety of surfaces.

PVA is used for gluing wood materials, as well as for the manufacture of furniture. But there is one drawback: the glue is not resistant to moisture.

Epoxy

The product contains resins and a hardener. But for gluing wood material, you must follow the instructions. Before applying the glue, mix the components thoroughly for five minutes. The surfaces to be glued are treated with a thin layer and pressed.

Can be used to join wood and other materials. The epoxy mixture dries up in almost a day.

Versatile and stable, but you need to be extremely careful when handling it - if it comes into contact with unprotected skin, it can cause itching and irritation.

Polyurethane

Due to its practicality and endurance, it enjoys immense popularity. Polyurethane adhesive is resistant to increased moisture, heat-resistant. In addition, it provides high-quality bonding of hard materials.

Casein

It is often used to bond different materials to wood, such as paper, cardboard, fabric or leather. One of its main advantages is its high resistance to moisture. To prepare the glue mixture, casein (powder) must be diluted in cold water until “sour cream” is formed.

The product dries up within five minutes, after which the surfaces can be joined. After 6-8 hours, the glue sets, it will take 20 hours to dry completely. It must be applied very carefully, as unpleasant marks can remain on the wood.

Syndeticon

It is used to connect wood with other materials. The composition includes dry wood glue, sugar and hydrated lime. The mixture should swell before use, then it can be applied to the surface in a thin layer.

Hot glue

It comes in special rods inserted into the gun, so it is quite convenient to use. With the help of heat-resistant glue, even small parts can be connected, since it is fed from the gun in a thin stream. The product hardens within a few seconds after application. As the name suggests, the adhesive cures at a temperature.

Joiner

It differs in the preparation procedure, but adheres the wood perfectly. It is applied to the wood along the grain and dries completely up to eight hours.

Paste

To prepare it, you need to mix hot wood glue with ash or chalk. This mixture can be used for primer or putty on wood, for gluing parts.

The BF series also allows you to glue wood and other materials together, but for its best efficiency, you will need special ovens or thermostats.

Liquid Nails

This type of connection is considered to be very strong. The main advantages of the product are resistance to high humidity, heavy loads, and safety. Such "nails" can glue porous and loose materials.

Urea resin

Urea-formaldehyde resins are used for the production of furniture, plywood, particle boards, OSB, foam, sawdust beams. The product contains urea and formalin.

Phenol-formaldehyde resins are also used for gluing wood. They are very resistant to external influences and are used in the production of waterproof plywood, load-bearing structures, parts from press crumb.

DIY making

You can independently prepare wood glue at home in several ways, but they are based on a single principle - soaking dry matter and subsequent cooking. For manufacturing, you will need to use granules or dry composition, water and a cooking container.

Recipe 1

Step-by-step instruction:

Pour the dry composition into a container and pour boiled cold water so that it completely covers the substance. After 8-12 hours, a gelatinous consistency should form.
Heat the mixture in a water bath at a temperature of 60-80 degrees, stirring regularly. As a result, the lumps must completely disappear so that the mass becomes liquid and homogeneous.
During the cooking process, hot water can be added to the mixture. If you plan to process end or spike joints, the composition should be thicker.
Once a film has formed on the surface, the joiner's glue is ready to use.

Recipe 2

Step by step process:

The adhesive composition in a dry state is mixed with water, observing equal proportions.
The resulting mixture is boiled until a dense material is formed.
Before direct use, the workpiece is dissolved in water and alcohol, and then boiled.

My services

I have the opportunity to help in organizing my own cooking of urea-formaldehyde resin. In this case, this glue will cost 3-6 rubles per kilogram. I provide various consulting services for resins and adhesives for wood.

In addition, there is a book on the manufacture of this glue, it is no longer even a book, but a technology. It has everything from equipment information to cooking technology. Everything is chewed, it is told about the dosages and parameters when cooking the resin.

In fact, the cost of such information costs about 100 thousand rubles. This is exactly how much my friend takes for setting up the technology. I give it away almost free of charge, in more detail about the technology in the "BOOKS" section.
