What is the best glue for wood. What glue is better for wood: instructions for gluing different materials among themselves

In everyday life, you have to perform various works with wood products - to repair something, restored, and then make it yourself. The use of traditional fasteners (nails, screws or other) is not always possible or appropriate.

In most cases, the optimal option is to glue the structural parts. Only that the composition is suitable for working with wood? How to choose the glue for the tree, what to provide? This article will answer all such questions.

Any glue is selected based on the specifics of its use. Therefore, before buying the composition, you should familiarize yourself with its properties:

• The time of final grazing.
• Bonding density.
• Moisture resistance.
• Universality of use, that is, adhesion with other materials, and not just with a tree.
• Connection strength, the ability to withstand dynamic loads.
• Degree of toxicity.

From these positions and consider the features of all as available on sale formulations for working with wood and cooked independently.

Types of glue

Plow

Such products are also called dispersed, polyvinyl acetate.

Main characteristics

• There is no toxicity. Consequently, such adhesive can be safely used to work with the indoor wood, without taking any precautionary measures (extract and the like).
• Speed. Primary grasp - approximately after an hour, final harvesting - per day.
• Possible processing of any surface.
• Deadline for glue - without restrictions.

Minus - since Pva is divorced by water, in premises with excessive humidity, the reliability of gluing is gradually decreasing.

Adhesive epoxy

A familiar to many set consisting of two components (resin + hardener), which must be mixed in a certain proportion before use.

Main characteristics

• Connection strength.
• Universality use.
• Epoxy adhesives are resistant not only to water, but also to fuel, row of aggressive reagents.
• The time of guaranteed drying (depending on the thickness of the layer) to 24 hours.

• When working with such adhesives, you need to take care of the protection of the skin. The compositions act annoying.
• Increased consumption. To determine exactly how many components should be breeding for a specific work, it does not work in practice. Part of the glue remains unused and thrown out.

Bf

Under this brand, several types of nevosa are sold. To glue the tree, including with other materials, the 2 "and" 4 "series are suitable.

Main characteristics

• Rapid drying - not more than 1 hour when normal temperatures and humidity.
• For internal work It is advisable to use "BF-2", outdoor - "BF-4".
• Such adhesives are applied in 2 layers, with an interval of 15 minutes.
• High moisture resistance, and the 4th series withstands low temperatures.

Minus - it is somewhat relative, but sometimes matters. Before applying such adhesives, the tree needs high-quality stripping and degreasing.

Heat resistant

Such adhesives are sold in the form of rods, so you will have to additionally acquire a special "gun".

The main characteristic is understandable from the name - increased resistance to high temperatures. Given the specifics of the application, similar compositions are used mainly to fasten small parts and for sealing cracks in the tree.

Joinery adhesives

They do not relate to products ready for use. Before gluing, it is necessary to prepare the composition.

Preparation specificity

• Dry mass is poured warm water and withstands from 6 to 12 hours, depending on the size of the dishes and the amount of glue. He must be completely soaked.
• "Water bath. A liquid is fused from the container, and it warms up steam to obtain a homogeneous mass. In the process of preparation, glue is periodically mixed until all solid particles dissolve. It is necessary to ensure that the composition does not boil! This is a prerequisite for obtaining high-quality glue.

Order of use

Segments to be glued together are drained in the direction of the fibers of the tree, even layer. After that, a dense clamp of parts and their fixation in this position. After 7- 8 hours, a complete hardened composition occurs.

Minus - the effectiveness of gluing with a tree moisture more than 10% decreases sharply.

Sindieticone glue

Prepared on the basis of carpentry adding lime (hawed) and sugar powder.

Main characteristics

• High gluing strength.
• Resistance to liquids and aggressive chemical compounds.

Minus is a long cooking process. Before use, dry mass is withstanding in water for at least a day.

Adhesive pasta

It turns out to be introduced into hot joinery glue shredded to the state of the poodle of chalk or wood ash. Such compositions are great for putting or priming a tree. The following materials are well bonded with it: glass, metal, stone.

Polyurethane compositions

It is more expensive than many types of adhesives for wood, and this is quite explained.

Main characteristics

• Place of gluing can withstand elevated dynamic loads. For example, the renovated leg of the chair is not overwhelmed over time.
• Inertness in relation to low and high temperatures, humidity, ultraviolet and so on. If the wood product is operated in extreme conditions, such adhesive is the optimal choice.

Glue casein

Who is engaged in aircraft modeling, with him a good sign. Such a composition on the tree can be highly secured the skin, paper, fabric.

Main characteristics

• Inertness to dampness.
• Connection strength.
• Full bitch - not more than 18 - 20 hours.

Minus - cooking requires accuracy and time. In the portion of the powder poured water (cold), after which a constant mixing of the mixture is performed. It is communicated to the state of sour cream, and so that the dry composition is completely dissolved, it will take at least 1 hour.

Tree adhesives are sold in various packaging. For the convenience of the reader in brackets after each name, the average price is indicated in rubles / kg.

According to the reviews of those who often have to deal with the tree, it is worth using brands of brands "Jowat" (204), "CASCO" (502 - PVA), "Kleiberit" (439), "Titebond" (from 260 per 310 ml), "Moment-carpentry" (478). It is with them that most professionals workshops work, especially since you can choose any modification, since their compositions differ, depending on the series.

The water resistance class is easy to determine the marking on the package with glue. Denoted by the letter "D". The figure standing behind it gives an idea of \u200b\u200bthe stability of the composition in front of liquids: 2 - low, 3 - sufficient, 4 - very high. But class D4 glues are quite expensive, so their use is justified only in cases where the product will be operated under constant dampness.

Glue is a mixture or substance, various multicomponent solutions that are made on the basis of organic and inorganic substances. With the help of glue, different materials are connected: fabrics, wood rocks, glass, metals, paper, leather, ceramics, rubber, plastics. Bonding occurs due to the formation of adhesion bond between the connecting surfaces and the glue layer. A cohesion to the adhesive surface can also affect the fortress of the glue seams. By type of gluing, all existing adhesives are divided into low-drying, drying adhesives and ligaments based on polymerizing compositions.

Joinery glue is used for durable fastening of parts from wood and other materials based on wood, for example, cardboard, plywood or organic.

The main component of this type of glue is a protein substance that provides durable bonding. Depending on the carbon black for wood used in the process of manufacturing raw materials, it is fish, bone, metering, etc.

Mind Clay

It is made of skin trimming, leather enterprises and meters - the subcutaneous fiber layer, which is cut into the stretch of animal skins.

Bone glue

Such glue is digested from bone wastes and grinding bones. This is the most common type of joinery glue.

Isinglass

It is manufactured from fish processing waste: fish head, inside, scales, etc. go into the course. Used, as a rule, when performing restoration and other complex workwhich require high quality and skill.

Casein glue

A brown-yellow powder manufactured from dry low-fat curd and alkali. In the process of manufacture, this powder falls into non-fermented water and constantly stirred.

PVA glue

PVA glue carpentry is released in tubes that can immediately use. It will quickly dry, is not washed off with water, but has a small shelf life. Despite this, he currently enjoys a great demand for people.

Mucilage

This type of glue was unable to find a wide introduction, because it has weak gluing parameters. It is mainly manufactured from starch and is used in the process of gluing wood surfaces and cloth.

Glue joiner "moment"

The glue "moment of the joiner" is intended mainly for carpentry work, which first includes a gluing of furniture parts. After 20 minutes after it is applied, the details are fixed, and after 24 hours the design acquires strength.

The Glue "Moment of the Stolar" has excellent adhesive ability and chemically neutral. The glued materials do not change their color and shape. The composition does not cause allergies and after complete drying does not leave the smell. The glue on the cleaned and degreased surface at a temperature above + 10 ° C.

Properties

The glue carbonaceous is distinguished by high strength: with huge loads, there is mainly the destruction of the nearby layer of wood design, and not the adhesive layer of the joint.

Glue is usually produced by yellow-brown granules or solid plates. It is believed that the more transparent and the lighter plate or granules, the better the quality of the glue.

Preparing glue before work

Before starting work, the gluery dry need to prepare. For this granules (when using glue tiles, it is necessary to wrap it into the cloth and smash the hammer on small pieces) in advance cold waterSo that the water covers dry glue. The mixture is maintained until it becomes a soft shape. Basically, depending on the amount of glue, the procedure takes 4-12 hours.

After swelling, the glue is cooked for 15 minutes with a constant stirring on a water bath at 60-80 degrees, until the monotonous liquid mass without lumps is formed. It is impossible to heat the glue on the usual fire - when burning or boiling the solution, its adhesive ability is significantly reduced.

For cooking, it is necessary to use special devices that are called "glue" having two metal vessels. In a large vessel pour hot water, after which a smaller vessel with glue is inserted, and the glue is put on a small fire. In the external vessel, water is poured so that it does not flow into the inner vessel with joinery glue. It is better to choose a glue made of copper.

If necessary, such a device is not difficult to make independently from the primary materials. For example, you can take a large tin can as a vessel, and to place a small glass jar that is installed on the stand or hang onto a wire.

To obtain the necessary consistency of the glue solution, during cooking or hot boiled water is added, or the cooking time is increasing for evaporation of excess moisture. For gluing thickening and end connections, glue is better to do a little curly than for a plane connection. sheet materials (organic, plywood, etc.).

You should cook the amount of carbon black glue, which will be required to perform the current work, because, despite the existing additives, with time the solution starts to lose its properties, and after three days it can be rotated and covered with mold.

Application

The glue isolar is used hot at temperatures up to 70 degrees before it thickening. As a rule, the glue is capable of maintaining the desired composition of the composition in room conditions without the need to additionally warm it up for 2 hours.

Glue carbon black is evenly applied to the gluing areas with a small brush.

In order for the hot solution is not very squeezed out, it is necessary to give the printed layer time to dry out - about 2-5 minutes. After this surface, the parts are connected, the parts are slightly groped to each other, compress the clamp (or firmly tightened with the help of the twine) and are left for 4-6 hours before their gluing.

For durable and high-quality gluing with joinery glue, it is necessary that the parts bonded are dry. Wood should not have a humidity more than 10 percent, veneer - no more than 5 percent.

Improving the quality of glue

When adding a variety of additives to the finished joyar adhesive can be made more versatile, suitable for connecting other materials other than wood.

For instance:

• Moisture resistance of the adhesive joint is significantly increased, if to 40 g of dry joinery glue add 10 g linen oil or natural olifa.
• To glue the skin to the joinery of the glue, it is necessary to add glycerin in the ratio of 1 tsp. On half liter glue.
• If you add sainted wood ashes or dry chalk powder into hot joinery glue for wood, you can get an excellent spacious paste.

Everyone who was engaged in the works related to wood processing, more than once wondered - what to choose adhesive for wood? There are many diverse firms and manufacturers, each of which offer certain properties and capabilities. So, what glue glue tree and what will give the best result?

Types of glue for wood and purpose

There are many varieties to solve certain tasks.

• PVA glue for wood. Perfectly glues the wood, "grasps" the material is approximately 20 minutes, but fully freezes per day.
• Glue series "BF". There are several varieties - BF-6, BF-4, BF-2. Provide high strength and leading. The glue completely dries in an hour, you can speed up the process of drying to 15 minutes, at a temperature of 80 degrees.
• Sindieticone glue. Designed for gluing wood and gluing different materials to it. Drying time of such a tree glue is about a day. Before use, it is necessary to warm it up and let it swell, only after that apply for work with wood.
• Glue "Moment" for wood - One of the common and universal means for gluing. Provides a practically instant "grasp" of a tree, can be used for glue wood with other materials.
• Epoxy adhesive. Universal in its use, can be used not only for glue wood, but also other materials. Glue waterproof and has good resistance to oil substances.
• Glue for wood heat-resistant. It is often used in carpentry work, due to its high resistance to thermal exposure - under the action of the temperature of the properties of conventional adhesive for wood are lost, it dissipates and lifted. The heat-resistant glue provides excellent resistance even with thermal exposure.
• Paste of glue. Another of the unusual types of glue, which is used for the priming and putty the materials of the wood. Such a paste is obtained as a result of mixing ordinary adhesive for wood and ash, or a sifted chalk.
• Polyurethane adhesive for wood. Provides excellent moisture resistance, well fills the seams, more resistant to long-term loads than others. It has a higher adhesion when gluing solid wood. The glue is very popular for a long time.
• Casein glue. This is a very waterproof adhesive for wood, which also provides good resistance to high temperatures. The glue is seized within 6-8 hours and completely freezes in 20 hours.

The best of the best

Determine what the best glue for the gluing of the tree is difficult, as for each goal it is great for its own species. However, when choosing a glue for a tree, it is worth considering the versatility of its use. Many are used only for certain purposes, while others can suit for adhesive various wood breeds, and for wood glue with different materials.

Such properties have adhesive for wood Titebond.. This is the only one-component type of wood glue, which satisfies the most stringent standards of Ansy II by moisture resistance. It can be used for all types of wood - both in rooms and out of them. This is the best adhesive for wood according to many experts and professionals working with him.

It remains only your choice, which glue is better for wood and what is the most suitable for your work.
