Which glues are better for wood. Wood glue - advice on selection and use. Preparation of glue before work

Wood refers to natural materials that a person constantly uses for construction, the manufacture of various structures and objects used in everyday life. To work effectively with wood, you need a reliable and durable fixing compound, which is a glue that is available on the market in a wide variety of types.

Specifications

New types of adhesives for working with wood constantly appear on the modern market, and products that have been used for a long time are being improved in order to occupy a leading position in the line of these products along with new products. When choosing an adhesive, one should focus on the characteristics of the product, in addition, the type of materials with which to work is considered an important factor. Based on these nuances, the compositions can differ significantly.

It is also necessary to take into account the conditions in which the product or structure will be used in the future, since there is no universal product that is ideal for all types of wood gluing without exception.

It is worth highlighting a number of characteristics of the glue:

Moisture resistance of products - this property of the material is indicated on the label with the letter "D". There are several options for the water resistance of the composition - class D2, D3, D4. The higher this value, the better the performance of the adhesive.
The composition must be non-toxic.
The level of strength of the joint formed. In most cases, a high-strength material is required to work with wood.
Density of products.

Adhesion to various substrates - wood can be reliably fixed not only with similar raw materials, but also with concrete, glass, rubber, fabric, mirror, tiles, there are compounds for gluing wood and metal on sale, as well as products used in shipbuilding, etc. etc.
The period of complete solidification of the substance.
Heat resistance of products.
Resistance of the adhesive to the development of microorganisms.
In some cases, a very important point is the color of the substance - the composition can be transparent or repeat the color of the tree, in addition, there are white and black products.

Composition

Given the composition of the products, it can be divided into two groups:

one-component gluing compounds;
two-component materials.

The first category includes glue, which is sold in liquid form, already completely ready to be applied to the working base. You can also find the composition in the form of foam glue. The second group of products includes formulations that require dilution and mixing of two ingredients to obtain a substance for gluing materials. As a rule, such a product is a polymer composition, which is marked accordingly - the first component is designated by the letter "A", the second - "B", the latter is the hardener.

The composition is prepared immediately before work, strictly following the specified breeding instructions. For mixing, a special tool is usually used, after complete dissolution of the components of the two-component adhesive, an elastic and homogeneous contact product is formed. Products can be of different colors.

Views

Based on the purpose and ingredients used to make wood glue, there is a wide range of products on sale. The most popular type of composition is PVA, it is familiar to everyone since childhood. This substance allows you to glue paper, wood and wood-containing materials. Its main requirement is the moisture-absorbing capacity of raw materials. The eco-friendly composition is a white liquid, thick in consistency, which, when solidified, becomes colorless. The main characteristics of the product include the fact that the glue dries quickly, is sold ready-to-use, the composition can be easily removed from the base if necessary, it can be diluted with water. On sale you can find various types of products that differ in their area of application.

Epoxy adhesive is a two-component product, solidification of the composition occurs without participation in the reaction of air. This product can be used not only for gluing wood, the material is often used to work with other types of raw materials. During the preparation of the composition, it is worth strictly observing the proportions, since errors in dosage will lead to the production of a foaming mass that is unsuitable for gluing. The solidification period of a substance varies depending on the brand of product.

Not so long ago, Glue BF belonged to the group of the strongest and most durable products for working with wooden bases. The scope of application of the composition includes gluing wood, iron, PVC, polyurethane foam and other raw materials. There are several types of this composition, but moisture-resistant BF-2 or BF-4 is best suited for fixing wood. The products are distinguished by a rather specific material processing technology, which boils down to applying a layer, drying and then compressing the elements with each other - this technique is needed for the strength of the splicing line.

Compositions that are resistant to various temperatures are represented by synthetic substances and varieties of epoxy materials. Among the list of products belonging to this category, one can single out the composition, which is sold in the form of a rod. They work with him with a pistol. It is used to repair furniture, to model various structures.

Joiner's adhesive composition is considered furniture, since it is in demand in this particular area of production., in addition, the products are used for repairing musical instruments. The reason why such a product has not gained wide popularity is the complexity of the work, because it is sold in dry form, which requires a number of works to prepare it for use.

It includes several varieties - sturgeon, skin, bone glue. These are environmentally friendly products that are made from organic substances. Products are sold in granules, and glue is also produced in the form of grains. Fish glue is mainly used as a professional composition for repairing musical instruments. The latter refers to gelatinous products. The main feature of such a glue for wood is the ability to soak the compound in water, as a result, the elements will move away from each other.

The syndeticone compound is necessary for fixing the tree to the tree. This is a homemade product that contains sugar, hydrated lime and wood glue.

Polyurethane glue is a super strong material that has high quality characteristics, refers to expensive products. Among the indisputable advantages, it is worth highlighting the moisture and frost-resistant nature of the product, due to which the composition is recommended for working with wood both indoors and outdoors. The moisture- and frost-resistant composition has the effect of filling the plane, ensuring the protection of materials and their joints. The expanding composition is allowed to work in the temperature range from -30 to +100 degrees. Can be used for hardwoods.

Casein wood glue has a completely natural composition. Such products are sold in the form of granules or you can prepare them yourself at home. The composition is used for MDF, chipboard, fiberboard, parquet, printing and painting. With the help of casein composition, elite furniture is made.

Among the disadvantages of the product, it is worth noting the hygroscopicity of the material, as well as the possibility of mold formation on its surface, but with proper storage, unpleasant situations with the composition do not arise.

Paste adhesives are used as assembly products for sealing small voids that prevent moisture penetration. They are heat-resistant and cold-tolerant. The heat-resistant product for gluing wood is rarely used, but for work with uneven substrates, the product will be an indispensable assistant.

Manufacturers rating

For wood, ready-made adhesives on a synthetic basis are more in demand. Among the brands that have proven themselves on the market for such products on a positive side, it is worth highlighting several manufacturers.

Titebond- compositions that are produced by an American company. Product specialization - the manufacture of furniture from wood and wood-containing materials, work with floor coverings, including tiles, finishing various structures with wooden elements. The formulations include artificial and natural ingredients, do not contain solvents and resins, which ensures a high level of adhesion of the bases to each other. In the review of the products of this manufacturer, the product "Titebond ii premium" should be highlighted, which is recommended for fixing paper products, wooden elements, in demand for the manufacture of doors and window blocks, chairs and other furniture. The products are allowed to be used for work outdoors and indoors. With the help of such adhesives, they decorate facades with wooden fittings.

"Moment"- the products of the German concern are widely used in the industrial and domestic spheres, the composition is relatively cheap, therefore it is convenient for small and large repairs. Quite often, these products are used to repair kitchen utensils - waterproof glue glues mugs, cutting boards, etc.

"Titanium"- a multipurpose composition, high-quality glues wood, glass, plastic and paper. It is sold in different containers - from 60 g to 1 liter. Among the assortment, one can single out glue-mastic, which is used for repair and finishing work with wood.

Application

To ensure a high level of strength of the connecting seam, you should competently approach the preparation of the elements for fixation. The wood must be well sanded, sawdust removed, and dust or existing dirt must be removed. If you plan to work with wood and porcelain or with glass, acrylic surface or plastic, the material must be degreased. Acetone works well for this.

Two-component polymer product offers multiple application options- in the first case, the compositions are mixed, forming a homogeneous composition, in the second version, each ingredient is applied to one of the materials, after which they are fixed with each other.

Varieties of wood glue are applied in two layers, allowing the previous one to harden a little. For flat elements, one layer can be applied, evenly spreading it along the location of the fibers on the material. For a more effective connection, the elements must be placed under a press or pressed against each other in some other way.

Quick-drying formulations do not need additional pressure. However, attention should be paid to the leakage of the substance at the junction - all excess must be promptly removed from the bases.

An important nuance when working with glue is safety measures, since even organic or one-component products can cause an allergic reaction in a person. Therefore, care must be taken to protect the skin and eyes.

Which one is better to choose?

A number of points can be distinguished at which it is worth focusing your attention when buying products:

For gluing wooden components forever, it would be more correct to give preference to a composition based on a synthetic base.
Gluing of structural elements, in which it may be necessary to dismantle the fixed parts, should be performed with adhesives on an organic basis.
For light types of wood, "Joiner" is most suitable. Based on the feedback from experts, casein formulations darken over time, which will make the connecting seam expressive against the general background. This option is not suitable for carpentry work in most cases.
When buying PVA, it is worth checking its homogeneity. The division of the composition into several fractions will indicate that the products were stored or transported in violation of conditions, as a result of which the glue was at sub-zero temperatures and was frozen. It is no longer possible to use such a composition in work.

Wood is the most common building material in Russia. Accordingly, the problem of its strong gluing is very urgent. The most common glue for wood is, undoubtedly, PVA and it has been used for more than 50 years and even now in construction it is difficult to find a worthy alternative to it.
The cheapest types of PVA glue for office supplies are, and in construction they are only suitable for pasting wallpaper. The second group is represented by PVA building adhesives, which are an additive in concrete and as a gluing for decorative elements made of wood, paper and pile coverings. This is followed by a group of adhesives for household needs and it is suitable for simple carpentry work. This group is the most popular among consumers. The fourth group includes adhesives that are designed for carpentry work.
Most consumers prefer to use variance the old fashioned way. And this is not a mistake, although it brings with it a number of inconveniences. One of them is the issue of plasticization. The plasticized dispersion is afraid of the cold, and when plasticized by the consumer, as a rule, the quality is lower than the factory quality. In the case of using ready-made frost-resistant PVA adhesives, this question disappears.
It should be noted that the use of PVA dispersion for gluing does not give a true increase in the strength of gluing wood.
The fifth group is filled with PVA types. These adhesives provide good strength but have special properties:
- the formation of white gluing seams, in place of the usual transparent ones;
- limited plasticity;
- dries in less time.
Such features should be taken into account while working with them.
Conventional PVA glue is made on the basis of an inexpensive homopolymer dispersion with limited water resistance. Moisture-resistant PVA wood glue is made on the basis of a copolymer dispersion, which is slightly more expensive. More preferable for such purposes are versatate copolymers and acrylic PVA, which are practically not produced in Russia, and imported adhesives are not cheap. But here it is better not to save money, since the products for which these adhesives are designed clearly do not belong to cheap products, and the share of adhesives at cost is negligible.
PVA glue for wood is moisture resistant, for gluing frames or sheathing of a wooden yacht, in turn, is not intended, but the railing on the porch or an open terrace for PVA glue is quite suitable.
The seventh group are specialized adhesives. They are intended for the woodworking and furniture industries. You can hardly find them on store shelves. Materials of this kind are intended for a narrow scope of special tasks that rarely arise in everyday life. Accordingly, the cost of such adhesives is quite high. If the wholesale price for general purpose PVA glue ends at the level of 1–1.5 dollars. US per kilogram, then in this class of adhesives, the countdown is just beginning from this mark.
From the point of view, in the class of general-purpose adhesives, a fairly high degree of adhesion strength is achieved up to 35-40 kg per square centimeter, pine strength (for comparison) for tensile strength along the fibers is 20-25 kg per square centimeter.
A further increase in strength here does not make sense at all, in other words, the rupture will simply occur along the "body" of the wood itself and will not depend on the strength of the glue. It is another matter that excellent durability is not dependent on external influences. Such influences include the temperature parameter and the degree of humidity. If we are talking about furniture that is used at room temperatures, then this factor is not so critical, but it should be taken into account.

Carpentry glue is often used. The tool provides a high-quality connection and has an affordable cost. It is used for reliable gluing of wood, wood, as well as chipboard and fiberboard. The main component of the solution is the protein component, the specific properties of the adhesive depend on the additives, which make it suitable for various applications. Before use, the adhesive mass must be properly prepared at home, its quality and properties depend on it.

Features of the glue

The main advantage of the adhesive material is its good strength. Even if the wood starts to deteriorate, the glue layer remains intact. The disadvantages include an unpleasant smell, as well as inconvenience in storage. If you keep the product in a liquid form, then it can become moldy. Use the glue mass in construction work only in a heated form. A water bath is ideal for these purposes. It is not recommended to heat the glue directly, as it may lose its unique characteristics.

When giving preference to dry glue, you need to pay attention to its appearance. Most often it is sold in the form of yellow-brown granules. The high transparency of the grains indicates excellent product quality. The consistency of the adhesive may vary. Some types of glue should be diluted with boiled water. It all depends on the type of material.

Cooking method

For working with wood, it is recommended to preheat the adhesive (up to 60-70 degrees). Water is added to the glue and heated in a water bath. The mixture is brought to a homogeneous mass similar in consistency to cream. During the cooking process, the composition must be constantly stirred so that the mixture does not have time to burn.

There should be no lumps and other defects, the glue should be homogeneous in density. After cooking, the mass is poured into a plate in a water bath. Gradually the composition cools down, forming the correct consistency. On a plate, the sticky mass is cut into separate strips with a knife, which are later used in carpentry work (preheating).

Which glue should you choose?

Each type of wood glue has its own special qualities. When buying, it is important to consider lightfastness, adhesive strength, biological resistance of the composition, etc. Having familiarized yourself with the characteristics of the various types of wood glue listed below, it will be easier to make the right choice.

In the assortment of each hardware store, you can find this type of wood glue:

If it becomes necessary to restore furniture, then it is better to take this particular adhesive. It is made on the basis of the air bubble and the fins of the fish. Externally, fish glue looks like scales with a transparent and elastic structure. It does not need to be preheated. Used fish carpentry glue at a temperature of 20 degrees.

It is recommended to use it for gluing materials with different hardness. The disadvantages of fish glue include the high price. It is not worth using it in a humid environment: under such conditions, the unique properties of the composition are lost.

For working with porous woods and materials containing essential oils, PVA glue is ideal. The seam will be as strong as possible if additional efforts are made during gluing, pressing and fixing the parts with force. It is not necessary to preheat or prepare the polyvinyl acetate glue, since it is sold ready-made. The adhesive has a long shelf life.

The main advantages of PVA:

seam stability;
resistance to sunlight;
elasticity.

Before use, such an adhesive material should be prepared by heating to 50 degrees. It goes on sale in the form of slabs or granules. You can determine the quality of the glue by its color: the lighter the composition, the better. To prepare the glue, the dry material must be filled with water in the proportions indicated on the package. Within a few hours, the granules should swell, and after that the mixture should be stirred and heated in a water bath. The whole process will take several hours.

Bone glue must be used hot, while it must remain liquid: it is desirable that it flow down from the brush in a continuous stream. If the bone glue is too thick, it must be diluted with hot water.

Possesses high strength; made of leather. It contains gelatin and oligopeptides. It is the last component that contributes to increased strength when joining parts. In the assortment of the hardware store, you can find skin glue in the form of powder, flakes and tiles.

Before use, the adhesive is diluted with water, left for several hours (the mixture should have time to swell) and later melted in a water bath. The skin glue has a light shade and is also characterized by a high viscosity. When working with this variety, it is important to consider the latter fact, since this feature can lead to the destruction of the tree.

Before using the product, it must be prepared (according to the scheme given above), then let it brew for 10 minutes, remove the foam, and only after that you should proceed to use. sold in powder form.

A mixture of this type is rather fragile, and its volume may shrink after application. This feature somewhat complicates the bonding process. Use casein wood glue carefully if the wood contains tannins. The use of glue in this case can lead to discoloration of the wood.

Advice
After preparing casein glue, it must be used immediately. Unlike other types of carpentry glue (which can stand ready-made for several days), casein glue will lose its properties in a few hours. If during the preparation of the product in a water bath it turned out to be too thick, then it is not recommended to dilute it with water.

Application rules

When working with the composition, it is important to adhere to the following recommendations:

It is better to apply the mixture with a bristle or bast brush.
One layer of glue is applied when the part needs to be glued along the grain of the tree. Two layers are distributed on the ends, a second layer should be applied only after the first has dried.
After a few minutes, when the wood glue has dried, the parts must be carefully squeezed and aligned. The remnants of excess glue are removed, and the parts are fixed with a bandage or twine for several hours until they are completely dry.

Advice
Adding ammonia, borax or phenol to the adhesive can increase the resistance of the mixture to mold. It will not be difficult to get a putty paste if ash or chalk is added to the glue.

By giving preference to proven carpentry glue, you are almost guaranteed to make the highest quality furniture or repair it yourself. Carpentry work will be productive if you adhere to important rules in the preparation and use of the adhesive mass.

Wood is one of the most popular materials in construction and many other manufacturing industries. Therefore, it is often necessary to glue wood parts in order to obtain. For this, a wide range of different compositions is offered, thanks to which there is no easier task than gluing wood to wood.

Types of glue

Of all the varieties of glue that differ in their composition and characteristics, it is necessary to choose the one suitable for solving the corresponding task in order to get the perfect result.

quickly and efficiently glues wood, leaving virtually no traces. But when exposed to water, as well as low and high temperatures, it partially loses its properties.
"Moment" is a universal waterproof glue for gluing wood and more. It is also effective for gluing other materials to wood. Provides instant grip.
for wood does not lose its properties under the influence of high temperatures, does not dry out or crumble. Therefore, it is most often used in carpentry.
characterized by increased adhesion when gluing hard wood. Provides full adhesion 20 hours after application. Not afraid of moisture, resistant to high temperatures and prolonged stress.
Casein glue has the same characteristics as polyurethane glue. The disadvantage is its ability to change the color of the glued wood.
suitable for all types of wood, dries completely after 24 hours and leaves no residue.

Which composition to choose

When deciding how to glue wood to wood, it is worth considering the versatility of using the adhesive. Some types are only suitable for working with a certain type of wood, others are capable of gluing completely different types of wood.

It is also of great importance what specific goals are required to be achieved, for example, to glue broken wooden objects or perform facade work. The composition of the adhesive and its quality play an important role in this.

Household recipes

There are many recipes for how to make high-quality wood glue with your own hands. To do this, you can purchase ready-made casein in powder form or get it at home. Put low-fat milk in a warm place for souring. When it is fermented, filter with cheesecloth and rinse the casein remaining as a result of this process in water and boil to remove fat. Then lay it out on paper, dry well and mix with borax (1 part borax to 10 parts casein) until the consistency of the dough. Dilute the resulting mass with water (2 parts) and apply the resulting glue immediately, since it hardens after 2 hours.

General rules for gluing

There are rules for gluing wooden parts, which must be observed regardless of which adhesive is chosen.

First you need to thoroughly clean the surface. This can be done using sandpaper or a file. After that, dry the parts and apply a thin layer of adhesive with a brush and rub in lightly. All surfaces intended for connection are lubricated with glue, then they are tightly pressed against each other using a press or in another way until the composition is completely solidified.

When working with any glue, compulsory observance of precautionary measures is required, since even the most innocuous composition can sometimes cause a severe allergic reaction. Therefore, the gluing of wood must be carried out with rubber gloves. If the glue does get on the skin, you need to gently wipe it off and thoroughly wash the affected area with soap. In case of contact with the eyes, rinse immediately with running water.

If you thoroughly figure out how to glue wood to wood, and strictly follow the instructions for using the adhesive, then the junction of the parts can be much stronger than the wood itself.
