Wood in our life

Nature has endowed wood with such a unique set of qualities that no other material on earth has: environmental friendliness, wear resistance, richness of textures, etc. It is impossible to list all the areas of its application. Here's just a short list:

• construction;
• furniture;
• paper production;
• musical instruments;
• toys;
• home stuff.

Despite the fact that this material is quite durable, it also tends to break, crack and split into pieces. In order to bring a damaged item back to life, wood gluing is necessary.

One- and two-component PVA adhesives

Application area . One-part polyvinyl acetate (PVA) resin adhesives are a versatile option for a variety of indoor wood projects. Due to their high moisture resistance, two-component compositions (with the additional inclusion of a hardener) are considered the best option for gluing wooden products used outdoors (garden furniture, elements of external doors, window structures).

Working properties . If used rarely, the composition may separate and form sediment. Therefore, it is recommended to shake or stir thoroughly before use. The glue is extremely easy to use.

Compatible with finishing compounds . Traces of dried glue appear under the stain and varnish layer.

Open time : 3-5 min.

The best polyurethane adhesives for wood

If the adhesive composition requires increased reliability, long-term resistance to mechanical load, resistance to moisture and negative climatic conditions, then it is advisable to use a polyurethane composition.

Two-component universal wood adhesive has good gluing properties. It is made of epoxy resin, which will allow materials of different origins to be glued to the wooden object being processed. The exception will be glass items. The composition hardens within 1.5 hours, the joints are fully ready for use within 12-24 hours. The seam will become impact-resistant, wear-resistant and moisture-resistant.

To make a working solution, you need to mix 2 ingredients, following the developer's instructions. Then the components are thoroughly mixed until a homogeneous consistency is formed. The finished composition is applied with a brush or spatula. Among the advantages of glue from a German brand, the emphasis is on high strength, resistance to mechanical influences, and moisture.

The safety of the mixture, which is used both for home and industrial purposes, is noted.

General gluing rules

There are rules for gluing wooden parts that must be followed regardless of what adhesive composition is chosen.

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

When working with any glue, mandatory precautions are required, since even the most harmless composition can sometimes cause a severe allergic reaction. Therefore, gluing wood must be done with rubber gloves. If glue does get on the skin, you need to carefully wipe it off and thoroughly wash the affected area with soap. If the composition gets into your eyes, rinse them immediately with running water.

If you carefully understand how to glue wood to wood, and strictly follow the instructions for using the adhesive composition, then the place where the parts are joined can turn out to be much stronger than the wood itself.

Which wood glue is best to buy?

To choose the strongest glue for wood, you need to consider its purpose and type. There are specialized products that are used directly for items of wood origin, and there are universal ones. Despite the variety, experts choose narrow-profile compounds that are suitable directly for wood and its derivatives. However, the characteristics of the wood in a particular situation also need to be taken into account when purchasing. Among the products reviewed, experts focus on the following nominees:

• Moment Super PVA D3 is moisture resistant – suitable for gluing wood in a humid environment;
• PUR adhesive Kleiberit 501.0, D4 – a universal product with fast setting;
• UHU Plus Endfest 300 is the most reliable product made from epoxy resin;
• Titebond carpentry is moisture resistant – suitable for carpentry work.

The rating includes the best adhesives for wood-based materials. It is impossible to answer the question which one is better. The choice of wood glue should also be based on the recommendations of specialists, builders, and positive and negative user opinions.

How to apply it?

TURBO FIX 805 has two application methods (hence two gluing methods):

FAST. Of course, we clean the surface of various irregularities or residues (as in my case of the old composition). I took sandpaper and simply sanded the surfaces, then wiped them with a cloth to remove any wood dust.

Next, apply the gel (from a small bottle) to one surface (spread it thoroughly).

And the activator, on another surface (just spray it). More details can be seen in the video below.

Then we press, observing the dimensions! IT IS IMPORTANT! Gluing occurs in seconds, and there is practically no time to fix it

We count to 10, the tree, in our case it is the balcony of the capital, just “grabbed” tightly.

LONG. The method is relatively long, it works not in seconds, but in minutes. Used so that you can adjust the size or fit.

We apply the gel on both sides, that is, on one and the other. We press them (combine the sizes), if necessary, adjust them - hold them. Next, spray the activator into the cracks (top and bottom). We hold it for a minute so that it initially sets, then leave it for a couple of hours (so that the activator penetrates inside) for final gluing. According to observations, after an hour, it can’t be torn off
