 In this tutorial, I will give you all the secrets I know about the different types of wood glues and tips and tricks for your daily work.

Types of Glues

The glue is always used to fix or repair wood, plastic or even metals, but first you need to know the different types of glues that you can find in the market:

  • Wood glue
  • Super glue
  • Epoxy glue
  • Neoprene glue

Wood Glue

One of the most types of glues that I use. Wood glue are used to, guessed it, glue wood. They are very useful for repairing a chair, fixing a baseboard or pieces of furniture, but beware; this glue is not water resistant, so avoid using it in a bathroom or wood that is always exposed to water.

The Super Glue

This all-purpose glue allows everything to stick almost instantly; it is very useful if you want to repair some broken dishes, a vase or a plastic toy. However, be EXTREMELY careful, this glue can dissolve some media and avoid contact with the skin. It dries quickly, it comes in small tubes, and the life of an open tube is short, so make sure you close it properly every time you use it.

Neoprene glue

This type of glues is not used very much by carpenters or contractors but it is used for attaching plastic foams, laminate panels, and metal panels. It also makes it possible to assemble different materials like (metal and wood, cork and plaster, wood and concrete, etc.). But be careful, most neoprene glues containing volatile and flammable solvents, so make sure that this glue is not exposed to flames.

Epoxy glue

This glue is made of resin; it is resistant to moisture and it becomes solid when dried. This type of glues is the best when dealing with anything in the bathroom or any pieces of wood that are constantly exposed to moisture or water. It is also used to bond between different materials like wood and concrete. The drying time is very important with this glue, it takes a little bit longer than the other types, so keep the pieces glued together as long as possible to insure maximum adhesion.

Different types of wood glues

Let’s return to our main topic, wood glues. There are several types of wood glue out there; each has its own use. These types are:

  1. Water-soluble PVAc glue (or white vinyl glue)
  2. Neoprene glue (or contact glue)
  3. Polyurethane adhesive
  4. Marine glue
  5. Aliphatic wood glue

Water-soluble PVAc glue (or white vinyl glue)

PVAc (polyvinyl acetate) is by far the most used type of them all. It becomes transparent and rubbery after drying.

The only drawback of this type is that it does not withstand heavy loads, humidity and temperature variations. Therefore, is used for indoor purposes and dry rooms, also for the assembly of light-weight wood parts.

Its surface drying speed is quite slow (1 to 1.5 hours), 24 hours will be sufficient for a complete drying.

Neoprene glue (or contact glue)

Neoprene glue allows fast and permanent adhesion, so it saves time!

It ensures the adhesion of the materials as soon as they are positioned, which makes that glue the glue of choice for the assembly of panels between and the gluing of veneer edges.

Polyurethane adhesive glue

Polyurethane glue is a mono-component glue, it is ideal for outdoor purposes or in wet rooms (kitchen or bathroom). It is resistant to temperature variations and humidity.

It ensures a very powerful adhesion for different types of materials: wood, glass, leather, fabric, plastic. On the other hand, it takes about 1 to 5 days for a complete adhesion, which is considered the drawback of this glue type.

Marine wood glue

Marine glue is ideal for wooden parts exposed to water, including seawater like boats. It is a two-component glue to mix. Its use is very popular in the sailing market in particular, but it is not used very much for indoor purposes.

Aliphatic wood glue

The aliphatic wood glue is widely used in stringed and wooden musical instruments, thanks to the absence of adhesive elastic during drying, it facilitates the sanding of the surface, and improves the finish quality.

This type is used when you are trying to fix a piece of furniture and then you want to apply some hand sanding on it.

The time of adhesion for aliphatic wood glue is 30 minutes and 24 hours for a complete drying.

Tips for using wood glue

  1. Before gluing the wood, make sure that the parts to be glued are clean, free of dust or moisture.
  2. Ensure that the room and the wood temperatures are higher than 8 ° C.
  3. Make sure that the joint being filled with wood glue is narrow and tight, not big and wide, the wider joints are not good and even if they are well filled with glue, they will have a lower adhesion.
  4. The tightening of the pieces is important for the good behavior of the bonding. You can use glue clamps for that :
  • It minimizes the thickness of the glue joints.
  • It penetrates part of the glue into the surrounding cells of the wood.
  • It rejects the excess glue to the outside removing a large amount of water that, not evacuated and delayed in drying.
This video will show you a live example on how to glue pieces of wood using glue clamps:

If you are like me, getting upset on the days when the stores are closed and have a piece of furniture to repair, then do not waste your time, you can make your wood glue!

How to make a DIY wood glue

Nothing very complicated in the manufacture of wood glue. Here are the steps:

  4. The mixture should be smooth and tacky.
  5. When using, it will be necessary to apply a generous amount of glue

You see, it’s simple as that!

How to take off the wood glue?

If the glued parts are not positioned correctly, the wood glue must be quickly peeled off after installation.

Nevertheless, there are few tips to take off the glued pieces more easily. One of the most reliable tips is to moisten the glued parts to take off:

  1. Start by wrapping the pieces of wood in a cloth soaked in hot water.
  2. Then let it rest for one to two hours, after this, the glue will be softened.
  3. Peel the glue off the surface with a knife, then heat the joint with a hair dryer.
  4. Pull, normally, the pieces and they should come off without resistance.
  5. Repeat if necessary.
Please make sure you wear a glove or anything that protects your hands before using wood glues.
