If you have already got the best wood glue for completing your project yet have faced certain troubles, get acquainted with this FAQ. You will most probably find an answer to the question bothering you.

For more information on making your own project, you can have a look at the following book.

What Are The Major Wood Glue Types?

Wood glue is a special adhesive for bonding two pieces of wood together (and quite often other materials as well). Actually, it can work on glass, plastic, metal, porcelain, etc. Not all adhesive liquids are equally efficient. If certain glue types are potent in all conditions, others are designed exceptionally for indoor applications (hobby-related tasks). There are five main types of wood glue you can choose from.

• PVA Glue

This is the most common type that can be found in nearly anyone’s house. These are versatile and waterproof. They are easy to use and mostly available in white. However, one must be cautious not to let extra dabs of the glue dry on the surface.

• Epoxy

Epoxy glue for wood is usually available in two parts—a hardener and a resin. Though both parts are liquid, the epoxy hardens once mixed together. This is a waterproof adhesive. As a rule, it dries as quickly as in several minutes. Yet, the longer you let the epoxy cure, the stronger the bond is.

• Hide Glue

This is one of the oldest yet most efficient types of glue you can find on the market. It’s very handy. It can be heated and applied to the target surface with a brush. As a rule, these adhesives come in powder form and need warm water to be solved. Yet, today there’s also liquid hide glue available. This type is highly versatile and can be applied to various surfaces unless the waterproof property is important.

• Cyanoacrylate Glue

Otherwise called “super glue”, this adhesive cures very quickly. It’s an all-purpose product suitable for various types of surfaces. Besides, it’s not priced expensively, hence will fit most users’ budgets.

• Polyurethane Glue

Activated by moisture, this is the best glue for wood to wood. As it dries, it swells naturally providing a super strong bond for the glued surfaces. The sealant is waterproof and reliable. Anyway, it is quite rough after drying.

What Is the Difference Between Good and Low-quality Wood Glue?

There are certain characteristic features that distinguish reliable wood glue from a low-quality product. To make the right selection, learn about the most important features.

• Bond Strength:

The bond strength of wood glue is reported in pounds per square inch (psi). It determines the unit applied in compression, tension, and impact necessary to break a bonded assembly with a failure that occurs near the plane of the bond. This feature determines how strong wood glue is.

• Closed Assembly Time:

This is the period between sticking the glued surfaces together and clamping them. The closed assembly time allows for moving the objects to the best position.

• Chalk Temperature:

It’s mandatory to provide a normal temperature when gluing and drying glued objects. In case the drying temperature is below the critical, this results in a white dried film in the joint known as “chalking”, while the critical temperature is referred to as “Chalk temperature”. Avoid such a phenomenon. This will result in a failed bond.

• Tack:

The feature of the glue enabling a firm bonding between it and the target surface right after they are brought into contact under low pressure is the tack.

• Freeze-thaw Stability:

This point determines the ability of the bonded object to remain usable once it has frozen and then thawed.

• Total Assembly Time:

This is the last significant feature to be aware of. It determines the whole period of time between applying the adhesive and clamping.

How To Choose The Right Wood Glue?

Choosing an adhesive for your wood project is a responsible task. You need to find the perfect variant that will be appropriate for the task, provide a strong bond and not ruin the material. Here are the most crucial points to take into consideration.

• Moisture Durability or Waterproof Feature

For outdoor projects, the sealant must be waterproof or moisture-durable. Certain types can resist water and various weather conditions, while others are designed only for indoor use. If the wrong glue is used outdoors, rain may separate the bonded pieces. Epoxy glues are known to be waterproof.

• Good Formulation

When buying the best wood glue for furniture or any other project, pay attention to the formulation. To ensure your safety, choose a non-toxic variant. If your project implies vertical bonding, the sealant must have a thick formulation. Additionally, opt for a versatile adhesive. The latter can be useful for sticking various surfaces including metal, vinyl, plastic, glass, ceramic, etc.

• Color Staining

Most often, sealants dry to different colors. If that isn’t an issue for certain projects, there are cases when it may appear as an eyesore. If that matters to you (you might need to fix a black vase, for instance), opt for variants that don’t have color stains and can retain the former beauty of the object to be bonded.

• Can Be Sanded and Painted

Some wood glues can be painted and sanded after drying, while others don’t give that opportunity. This feature ensures the pieces attached will get a smoother and better finish. Most wood glues and PVA, in particular, can also be painted after drying so that the glue’s unpleasant color isn’t visible.

Interesting Facts about Wood Glue

1. One square inch of cyanoacrylate (superglue) is capable of holding approximately one ton!
2. Superglue is more efficient if the surface is dry. Take this into consideration when you glue fabric to wood.
3. The first records about the use of wood glue date back to Ancient Egypt. As shown in hieroglyphs, a compound made from animals was used to glue the casket of Pharaoh Tutankhamun.
4. Superglue was first used in medicine during the Vietnam War. It efficiently and quickly closed open wounds.
5. It’s estimated that in the US, around 18 kg of glue is used for every person per year.

How To Get The Best Result While Using Wood Glue?

Before we reveal the top-rated wood glue of our investigation, we are going to provide you with some important tips on how to use wood glue. Take these recommendations seriously and you will get even better results:

1. If you are going to bond different species of wood, make certain they have an identical moisture content.
2. Start by bonding end grain joints.
3. Use a vacuum press to decrease the clamping time.
4. If you have undertaken to glue oily wood species, wipe the joints with acetone or sand them for better results.
5. If you are going to reuse a cartridge, let it heat extra several minutes. This way the dried sealant in the tip will extrude easier.
6. Even if the project doesn’t require clamping, it will ensure a thinner and more beautiful glue line.
