You can use a brush, dip it into the hide glue and then brush it in the area where you need to glue pieces of wood together. This type of glue is suitable for almost all types of woodworking project.
This type of glue will not cause damage to the structure of the wood over a long time. However, it is not waterproof.

This type of glue is made of resin and hardener. These liquid materials, when they are mixed together, become thicker.
Two main advantages of this type of wood glue are that it is waterproof and it can fill the small gap between two pieces of wood effectively. The other types of wood glue wouldn’t be able to stick two pieces of wood together when there is a gap between them but Epoxy can handle this problem easily.

3. Cyanoacrylate glue
Cyanoacrylate glue is also known as Super glue.
This type of glue is a great choice if you want to join two pieces of hardwood together. It can become dry in a short amount of time as well.

Since it is hard, these two pieces of wood which is glued together can become fractured in case of a strong and powerful impact.
How long does this wood glue take to dry? It would take about 3 to 4 minutes for Cyanoacrylate glue to dry. If you apply accelerant, it would even take a shorter amount of time.
4. Polyurethane glue
This type of wood works with moisture to become thickened, swell and then eventually dry. When this type of glue is dry, it is very hard and tough. It is also waterproof.
However, since it is quick to dry and since it dries hard, it is a little bit troublesome if you want to clean off the glue. You have to act quickly or it will leave dirty mark on the surface of the pieces of wood.
How long does this wood glue take to dry? It would take a very short of less than 3 minutes for this glue to dry.
More information on time for wood glue to dry:
The type of wood is only one factor that determines the time it takes for a piece of wood to dry. There are several factors that can influence how quick or slow it is for the glue you apply on pieces of wood to dry.
- Wood porosity: The type of wood which is more porous will be harder for glue to stay on its surface and create a wet layer. Hence, it will take longer time for wood glue to dry. On the other hand, if you have a very dense piece of wood, the wood glue wouldn’t be absorbed onto the wood. When a layer of wood glue can stay on the surface, it would be able to thicken and attach two pieces of wood together.
- Level of moisture inside the wood: Just like the porosity of the wood, the more moisture a piece of wood has, the slower it is for any type of wood glue to dry. The reason for this fact is quite simple. When a piece of wood is very moist, it couldn’t be able to absorb any particle of water. Hence, the water from any type of wood glue needs to evaporate naturally, taking longer time for that wood glue to dry.
- Temperature: If you handle your woodworking project in the summer, you will realize that it would take a shorter amount of time for any type of glue to fry.
- Humidity: If it is humid outside, it would take longer for wood glue to dry. Just like when the piece of wood is moist, when the air is high in humidity, it couldn’t absorb any particle of water from the wood glue. As a result, it would take longer for a wood glue to dry,

- Size of the project: Normally, any type of wood glue that takes longer time to dry will be more suitable for larger projects and for bonding larger pieces of wood.
- How long do you want to wait? If you want a type of glue which is quick to dry, go for either super glue or polyurethane glue. They can dry in a very short amount of time, from around 2 to 3 minutes. Other types of glues including Epoxy and hide glue also take no more than 5 minutes to dry.
- Do you need to fill a gap between two pieces of wood? If you need to do so, go for Epoxy.
- Can you work quickly? The thing is, as super glue and polyurethane glue are quick to dry, you need to act quick to clean off the mess that the glue left behind on the surface of the pieces o wood.
