When you are working on wood projects and don't want to use a hammer and nails to connect two pieces of wood, wood glue is a good alternative. You might be wondering if wood filler can be used as glue. We conducted in-depth research to answer this question.
Wood filler cannot firmly join two pieces of wood together. The wood filler can easily fill in cracks and holes, but it has a weak binding ability.
On the other hand, wood adhesives are used in most stages of making wood furniture or other wood projects. Wood adhesives are designed to join wooden materials together or with other types of materials.
That's a lot of information to take in! If you want to know more about wood filler and wood glue, just continue reading this post, as we break down each topic for you.

What Is The Purpose of Wood Filler?
Wood filler only acts to patch up dings, dents, and gouges in unfinished furniture. It also acts to repair any holes and gouges in a wooden floor. Even gaps between flooring boards can be filled with a wood filler when resurfacing a wooden floor.
But you can't use wood filler to connect pieces of wood, because it only contains a sandable compound coated in a hardening resin solution that can penetrate and bond with wood fibers is called a wood filler.
What Is The Purpose of Wood Glue?
Normal wood glue is the best type for raw wood-to-wood projects. Most wood glues contain a kind of polyvinyl acetate.
Wood glue, which is also known as carpenter's glue, will permeate the fibers of the wood and form strong, long-lasting bonds.
What Are The Different Types Of Wood Glue?
You can join two or more pieces of wood together in a variety of ways. You can screw them together, nail them together, or use other wood joinery methods to put them together, but glue is an easy alternative.
These different types of glue will help you finish your wood project:
Polyvinyl Acetate Wood Glue
PVA glue, commonly known as polyvinyl acetate glue, is the most widely used wood adhesive in use today. You probably already have it in your home or workspace because it is so prevalent.
There are several variations and forms of it. One of the most popular glues is yellow aliphatic resin carpenter's glue, which has been around since the turn of the 20th century and is a vital need in wood construction.
Yellow Glue
In terms of yellow glues, Titebond is the industry leader and offers a variety of options based on the project you're working on.
- Titebond Original - it is simple to use, non-toxic, and water-based in its cleanup. To shorten clamp times, Titebond Original offers a robust initial tack and quick setting speed. Along with offering superb ability, it also establishes a connection stronger than the wood itself and is resistant to finishes.

- Titebond II - Over the past few years, Titebond II Premium has consistently ranked as the top-selling wood glue. It is good for numerous outdoor applications as well as inside woodworking. Due to Titebond II's water resistance, it can be utilized to create items like cutting boards and outdoor furniture that will be in contact with water.

- Titebond III - Moisture activates Titebond polyurethane adhesive, which speeds up the curing process. But as this glue dries, it foams, making it essential to grip parts firmly while it cures. It can be used for projects that will be submerged in water or projects that frequently come into contact with water since it is waterproof or more water resistant than Titebond II.

Polyurethane Glue
You have used polyurethane glue if you have ever used Gorilla Glue. When different kinds of isocyanates react with polyols, polyurethane adhesives are created.
The polyurethane group makes it possible to adhere to different surfaces. Achieving glue lines with rubber-like flexible to flaky characteristics depends on the raw ingredients used.
Different materials, including ceramics, metal, stone, cloth, and wood, can be joined together using polyurethane glue because it creates a highly strong adhesive.
However, you must exercise caution when using it on tasks requiring final assembly because it expands as it dries and can very rapidly create a mess on your product.
Therefore, it is advised to use it only on projects that still require sanding or planning to achieve the desired surface.

Cyanoacrylate Glue
Normally, quick-bonding super glues are typically referred to as cyanoacrylate glue. They can be utilized to connect many materials, including plastic, metal, and even human skin.
It can glue practically anything, but it's not designed for extensive adhesives. It works well for quick fixes like repairing cracked or chipped woods. It is available in both liquid and gel form and dries very quickly.

Hide Glue
Hide glue is one of the earliest types of adhesive still in use today. It is also known as animal glue. Due to its capacity to be re-moisturized with heat and water, hide glue is very useful when it comes to repairing or restoring wood.
The open time of hide glue is pretty lengthy. This is particularly useful while working on complex and minutely detailed tasks.
Hide glue gives you time to work before fully curing, in contrast to hot melt glue or liquid glue, which (depending on the formula) will cure in a matter of seconds.
Hide glue often occurs as dry flakes or pellets that are melted down in twin boilers and then applied while still warm.
Any hide glue joint may be loosened by simply applying heat, allowing you to disassemble the furniture and make repairs. In contrast to other glues, hide glue is non-toxic and can also be dyed.
There are already liquid versions available like Titebond's. The traditional hide adhesive still creates the best bonding because it doesn't contain any additives that would reduce the durability of the glue.
Because hide glue has some advantageous characteristics, it is the glue of choice when building antique furniture or undertaking projects that you intend to disassemble for future repairs.
Epoxy Glue
Epoxy is a two-component adhesive. One component is a hardener, while the other is a resin. They combine to make a strong adhesive that is mostly used to fill gaps in wood and repair damaged wood. When combined properly, it hardens.
Numerous epoxy adhesives have been marketed and are frequently used to attach metals, concrete, glass, ceramics, concrete, numerous plastics, and wood in a wide range of industrial products and applications.
These adhesives are produced in one-component or two-component packages. They can withstand a variety of environmental factors, including heat, water, and UV light. Additionally, they stick to a variety of materials, including metal and plastic.

How Long Does Wood Glue Take To Dry?
When using polyvinyl acetate wood glue, you have anywhere from 5 to 20 minutes for complete assembly before the object is able to complete the initial set.
The bond between the wood and the majority of glues will be stronger than the surrounding wood after 24 hours of curing.
For super glue, the parts should be left undisturbed for at least 10 minutes to achieve maximum adhesion. In 24 hours, the adhesive will have entirely dried. Once opened, super glue vials can soon dry up.
Polyurethane glue takes up to 24 hours to fully dry. It dries to a sticky state in about 30 minutes. Consider using the best glue brush to precisely apply the adhesive before compressing the joint and waiting, since polyurethane takes a while to set up in contrast to CA adhesive.
Hide glue cures in between 12 to 24 hours, which is like the other glues mentioned above. Hide glue starts to set when it cools and starts to cure as the water evaporates from it; hide glue won't cure if it's been drenched.
For epoxy glue, the normal curing period is seven days. There are exceptions, but if you're looking for a general guideline, one week is the best option.
Should Glue Be Matched With Screws?
When two pieces of wood butt up against one another, wood glue and screws should be used to seal the junction. Wood glue is sufficient on its own for other woodworking joints.
You should only use screws instead of wood glue if you intend to take the object apart.
Does Wood Filler Form Without Hardener?
Typically, a mixture for hardening incorporates wood filler. Hardeners are applied to a damaged area of wood or an area that impairs the wood's structural integrity. For many woodworkers, salvaging a damaged or rotten piece of wood is the last resort.
Conclusion
Wood filler is commonly used to repair damage such as cracks, dents, and small holes but it doesn't have an adhesive element that can connect two pieces of wooden material together.
It is highly recommended to use wood glue when you are connecting two different pieces of wood.
Now that we have it covered for you, you can choose a wood glue that fits your project. Always consult first with the expert woodworker so you could easily identify pre-occurring problems and make an initial move!
