How to glue a wooden chair

Wooden furniture, in particular chairs, is an element that complements the interior of probably most residential premises. Many of them are not only functional, but also aesthetically pleasing. Unfortunately, wooden products, unlike those made from artificial materials, consist of a large number of elements and tend to become loose, begin to creak, or may even fall apart. There is no need to rush to get rid of them and send them to a landfill. Often, all you need to fix and continue to use your favorite chair is some glue and a couple of simple tools.

Types and characteristics of glue: which one to choose

The most important characteristic when choosing an adhesive is the strength and durability of the connection; it is this factor that should be taken into account first. It is also worth paying attention to toxicity (especially if there are children in the house), resistance to environmental influences and the presence of traces after processing. The appearance of the product can be spoiled by incorrectly selected glue.

Several types of glue are used to join wooden furniture parts, the most popular of which are:

1. PVA (polyvinyl acetate), and others based on it. It is time-tested, reliable, absolutely non-toxic and environmentally friendly. The advantages also include low cost, accessibility, and no need for special preparation before use.
2. Syndeticone adhesive is characterized by increased resistance to physical stress, chemicals and liquids. Its disadvantage is the very long preparation process before application (about a day before dissolution).
3. BF is characterized by excellent moisture resistance and resistance to low temperatures. Its drying time is about 1 hour, which makes working with it more convenient. Disadvantages include poor adhesion of non-greased and poorly treated surfaces.
4. Epoxy adhesive has very high bond strength and resistance to a wide range of aggressive reagents. It is good because it has high versatility and can be used in many places in everyday life. A minor drawback is the increased consumption (it may not be all consumed, and after mixing the components it cannot be stored).
5. Polyurethane adhesive copes better with dynamic loads than others. Excellent resistance to environmental influences and chemical reagents.

REFERENCE! As a substitute for expensive polyurethane, you can use regular polyurethane foam. To do this, you will first need to knock it down with a hard object, such as a spatula, to get rid of air bubbles. The connection made with it will be very strong and able to withstand enormous loads.

Leg gluing and complete repair

Once you have decided on the choice of glue, you should make sure that you have the necessary tools. It has a significant influence on the strength and durability of the connection. For successful repair you will need:

1. Sandpaper, sharp knife, chisel. Used to remove old glue residues, remove grease and prepare the joint of a leg or other part.
2. Hammer.Required for reliable and tight driving of the tenon into the groove. It is important that it has a rubber nozzle (to avoid damage to the varnished coating).
3. Clamps. To tighten the parts tightly. Pressing the glued parts of the chair as tightly as possible is not the least important element of a successful repair. In some cases, belt clamps are perfect.

To tighten parts, it is also possible to use improvised means, for example, ropes or a heavy object.

There are several main stages of repair:

1. First you need to disassemble the chair. Pull out the loose leg and other parts that will prevent easy access to the damaged connection.
2. Using a knife, chisel and sandpaper, clean the surface of the tenon and groove (trunnion).
3. Lubricate the joint with pre-prepared (if required) glue according to the instructions. Place the part in its place.
4. With light blows of a hammer with a rubber nozzle, hammer the tenon into the groove until it stops.
5. Remove the squeezed out excess glue from the product. A piece of ordinary fabric will help with this.
6. Press the joint using clamps or improvised means.
7. Wait for the glue to dry completely according to its instructions.

So with a few simple operations you can give your furniture a new life. This is especially important when you need to glue together your favorite chair, which you don’t want to replace with a product made of plastic and metal, because high-quality wooden furniture, although it costs much more, is more durable and aesthetically attractive.
