What is the best glue for wood: TOP 13 best adhesives

Advantages and disadvantages of different types of wood adhesives

How to choose the right glue

To correctly buy wood glue for wood, you need to know the types of compositions. There are special compositions only for wood planes and multi-purpose adhesives. Which are designed to work with metal, polyvinyl chloride, etc.

There are compositions designed to connect only homogeneous materials (wood to wood). And there is wood-metal for connecting dissimilar planes. But masters with many years of experience give preference to special compounds in one direction.

When purchasing, the properties of the wood material are taken into account.

These properties include: humidity, resin content, under what conditions the product will be used.

Some adhesives can withstand light loads, so they are used for gluing small parts. Items subject to constant shock, vibration, and physical stress must be held together with durable mixtures.

Wooden surfaces are constantly used in human life, so the material used for repairs or repairs should not contain harmful impurities with a pungent odor. If the product involves contact with food, it should be glued only with food glue, which does not harm the body.

Before buying glue in a store, you need to take the advice of experts and study the rating of the best glues for wood.

Wood gluing technology

Before starting work, it is recommended to stock up on all the necessary tools and protective equipment. Overalls, goggles and a respirator will protect the respiratory tract from harmful fumes, glue residues and wood dust.

Any wood glue will give excellent results if the surface is carefully leveled. Well-dried wood is sanded with fine sandpaper, cleaned of dust, and then degreased.

Wood of different types is glued together approximately the same way:

• The parts must be positioned horizontally so that the mass does not flow to one side. The glue is applied in a zigzag pattern to spread it freely over the surfaces;
• Working with two-component compositions is no different from other adhesive mixtures, only the base is applied to one contact wooden surface, the hardener is applied to the other;
• For better adhesion, wood glue is applied in a double layer, allowing the initial impregnation to dry a little. Next, these parts are connected and pressed tightly to enhance adhesion strength;
• When gluing, excess composition appears on the seams; they cannot be left until polymerization. In liquid form, the glue is much easier to remove. Depending on the density, the excess is cut off with a knife, removed with a sponge with a solvent, or wiped with a rag.

Any wood glue will give excellent results if the surface is carefully leveled.

Do I need to degrease surfaces?

Most offers on the consumables market are marked “Clean and degrease the surface.” Compliance with standards is the best prevention of poor-quality connections. It is important not only how to properly clean, but also how to degrease the surface. The main problem is to completely remove grease stains and resin pockets from coniferous wood.

Removing oily stains from wood is done with a soft cloth soaked in a suitable solvent. Mechanical cleaning and sanding with fine sandpaper of the area prepared for gluing wood is often required.

How long does it take for glue to dry?

GOST 17005–82 standards are carefully thought out for all glue groups. They regulate the class of the composition, according to its physical and mechanical qualities. Each variety has its own application technology and drying time for the composition. Often, novice carpenters and carpenters are a little disoriented by this diversity.

In order not to get confused with the technology, novice craftsmen use the instructions on the packaging of glue for wooden structures. There are four resistance groups, differing in bond strength and degree of moisture resistance. For high-quality gluing, it is important that the selected composition meets the basic operational requirements.

The gluing time for all compositions is different - from 2 hours to 24 hours (indicated in the instructions). If the parts are kept under pressure in a room with optimal temperature and humidity, the holding time can be reduced.

You should not subject the product to increased load for the first 2-3 days, since polymerization and slight absorption of moisture from the glue are still ongoing. PVA wood glue is an ideal product for working at home; drying takes about 24 hours.

The gluing time for all compositions is different - from 2 hours to 24 hours.

About glue water resistance classes

In Europe, each construction and other product has its own definitions. As for glue, it also has designations. Most often, when talking about this, they mention the water resistance classes of glue according to DIN EN 204 standard , which has successfully taken root in Russia.

Let's talk briefly about each of these classes.

1. D1 . Lowest water resistance class. Adhesive compositions of this class can be used indoors, the temperature in which is less than 50 degrees Celsius. The moisture content of the wood should be no more than fifteen percent. Brief exposure to water is allowed.
2. D2 . A little higher class. It can be used in the same rooms, but the permissible moisture content of wood material is slightly higher - up to eighteen percent. Brief exposure to water is allowed.
3. D3 . Quite a popular class of glue. It can be used not only inside a house or apartment, but also outside. Brief exposure to water is completely acceptable. At the same time, D3 class adhesives themselves can be used with more damp wood materials.
4. D4 . Like the D3, the D4 is suitable for both indoor and outdoor use. Withstands exposure to water, but still requires a protective coating to protect the adhesive.

Each water resistance class has its own characteristics

What glue should I buy?

If you do not consider yourself an experienced craftsman or if we are talking about small carpentry or repair work, then it is best to use bone (protein) or PVA glue. These products set quickly and dissolve easily and do not require prolonged pressing. Moreover, they are easy to remove from clothes if you accidentally stain them.

If we are talking about more complex work, then it is better to purchase polyurethane glue. Because its adhesive force is maximum and it provides effective fixation of any wood elements. However, do not forget to take precautions when working with such products. That is, prepare in advance means that provide personal protection.

The best PVA wood glue

One of the most environmentally friendly wood glues is a water emulsion of polyvinyl acetate. There is no toxic odor during work, so ventilation is not a mandatory requirement for a carpentry workshop. The availability of the product allows it to be widely used. Experts paid attention to several models.

Kleiberit 303.0

• not detected.

Some tips for proper use

When using, you must take into account the advice of the experts:

• Wooden parts for gluing should not have a moisture content of more than 12 percent (sometimes up to 18).
• For wood with high humidity, polyurethane adhesives are used, which are able to draw moisture out of the wood.
• The outside air temperature during the gluing process must be at least 18 degrees, then high-quality gluing will occur.
• Excess glue, before polymerization, is removed with a damp cloth or rag.
