Checkout this video:


Cyanoacrylate adhesives, commonly referred to as “CA glues” or “super glues”, are strong, fast-acting adhesives. They are typically used for bonding hard and brittle materials, such as wood, metal, glass, and plastics. CA glues come in different formulations that vary in strength, speed of cure, and flexibility. Choosing the right CA glue for your project can be a bit confusing. In this article, we’ll help you select the best CA glue for your needs.

What is CA Glue?

CA glue is an acronym for cyanoacrylate adhesive. It’s a quick-bonding, strong adhesive that’s widely used in woodworking, metalworking, and other applications.

CA glue is available in different formulations, each of which is best suited for specific applications. For woodworking, the most common types are thin CA glue, thick CA glue, and gel CA glue.

Thin CA glue is perfect for bonding small parts and tight fitting joints. It has a low viscosity and wicks into joints for a strong bond.

Thick CA glue is ideal for bonding larger parts or filling gaps. It has a higher viscosity than thin CA glue and won’t run or drip as easily.

Gel CA glue is perfect for vertical applications or bonding porous surfaces. It has a thick consistency that prevents it from running or dripping.

To choose the best CA glue for your project, you need to consider the type of joint you’re trying to bond, the materials you’re using, and the environment in which the adhesive will be used.

The Different Types of CA Glue

Choosing the best CA glue for woodworking can be difficult because there are so many different types on the market. CA glue, also known as super glue, is a strong adhesive that is perfect for bonding wood. However, not all CA glues are created equal. In this article, we will discuss the different types of CA glue so that you can make an informed decision about which one is right for your woodworking projects.

Cyanoacrylate Adhesives

Cyanoacrylate adhesives are fast-acting “super” glues that bond strongly to a wide variety of surfaces. They are typically used for bonding smaller items and for repairing broken items. You will often see them advertised as “gap filling” adhesives, as they can bond surfaces even when there is a small gap between them.

There are different types of CA glue, each with its own advantages and disadvantages. Here is a brief overview of the most common types:

Instant CA glue: This is the most common type of CA glue. It hardens very quickly, making it ideal for bonding small pieces together. However, it can also be difficult to control and can cause skin irritation.

Gap filling CA glue: This type of CA glue is designed to work well on surfaces with small gaps between them. It is typically thicker than instant CA glue and takes longer to harden.

Flexible CA glue: This type of CA glue is designed to be more flexible than other types, making it ideal for bonding materials that may need to expand or contract slightly (such as wood). However, it is also more expensive and not as strong as other types of CA glue.

UV-curing CA glue: This type of CA glue hardens when exposed to ultraviolet light, making it ideal for use in difficult-to-reach places or for bonding clear materials (which would be damaged by exposure to regular light). However, it requires special equipment to use and is more expensive than other types of CA glue.

Acrylic Adhesives

Acrylic adhesives are fast-setting, waterproof, and resistant to both hot and cold temperatures. CA glue comes in different thicknesses, but all have the same basic properties. The thicker the glue, the longer it takes to set.

Thin CA glue is great for bonding small pieces or for getting into tight spaces. It has a fast set time and dries clear, making it ideal for use on clear or porous surfaces. Thin CA glue is also good for spot repairs because it doesn’t require clamping and sets quickly.

Medium CA glue works well on larger surfaces and can be used for both indoor and outdoor projects. It has a slightly longer set time than thin CA glue, but still sets quickly compared to other types of adhesives. Medium CA glue is also weather resistant and can be used on porous and non-porous surfaces.

Thick or gel CA glue is perfect for filling gaps or voids because it doesn’t run or drip like thinner versions of the adhesive. Thick CA glue has a slower set time than other types of CA glue, so you have more time to adjust your project before it dries. This type of adhesive is also waterproof and can be used on both porous and non-porous surfaces.

Selecting the Right CA Glue

When working with wood, it is important to select the right type of glue in order to ensure a strong bond. Cyanoacrylate, or CA, glue is a type of glue that is often used in woodworking. CA glue is available in different formulations, so it is important to select the right one for the job. In this article, we will discuss the different types of CA glue and what each one is best suited for.

Woodworking Projects

Whether you are a professional woodworker or a hobbyist, choosing the right CA glue is important to the success of your project. With so many different types of CA glue on the market, it can be difficult to know which one is best for your needs.

In general, there are three things to consider when choosing a CA glue: bond strength, cure time, and viscosity. Bond strength is important for applications where the joint will be subject to heavy stress or vibration. For example, if you are joining two pieces of wood that will be used to support a piece of furniture, you will need a CA glue with high bond strength.

Cure time is also important to consider, especially if you are working on a project that requires quick assembly. There are two types of CA glue: instant-bond and time-cure. Instant-bond CA glues have a shorter cure time and are ideal for applications where quick assembly is required. Time-cure CA glues have a longer cure time but provide a stronger bond.

Viscosity is another factor to consider when choosing a CA glue. Viscosity refers to the thickness of the glue. Thickness is important because it determines how much of the glue will be absorbed into the surfaces you are bonding together. If you are bonding two porous surfaces, such as wood, you will need a thicker CA glue in order to avoid having the glue absorb too much into the surfaces and weakening the bond.

There are three main types of CA glues: superglue, gap filling superglue, and epoxy. Superglue is typically used for small projects where precision is not required. Gap filling superglue is thicker than regular superglue and is designed for applications where there may be gaps between the surfaces being bonded together. Epoxy is the strongest type of CA glue and is typically used for larger projects or applications where high stress or vibration may be present.

To choose the best CA glue for your project, consider the factors listed above and select the type of glue that best meets your needs.

Consider the Type of Joint

There are three main types of joints:
-Butt joints – This is the simplest and most common joint. It’s simply two pieces of wood glued together at their ends, flush with each other.

-Miter joints – This joint is similar to a butt joint, but the ends of the boards are cut at an angle (usually 45 degrees) so that they fit together like a puzzle. Miter joints are often used for picture frames, molding, and other trim work.

-Dado joints – A dado joint is a type of rabbet joint (described below), but the groove is cut into both pieces of wood instead of just one. Dados are often used to join shelves to a cabinet or bookcase.

There are many different types of wood glue, but they can generally be categorized into two types: carpenter’s glue and white glue. Each has its own advantages and disadvantages, so it’s important to choose the right one for your project.

Carpenter’s glue is best suited for projects where strength is important, such as furniture or architectural millwork. It has the advantage of being waterproof, so it can be used outdoors or in damp environments. However, carpenter’s glue is more difficult to use than white glue because it sets very quickly (in about 5 minutes). Once it sets, it cannot be reapplied or adjusted.

White glue is best suited for projects where a strong bond is not required, such as arts and crafts projects. It sets more slowly than carpenter’s glue (in about 30 minutes), so you have more time to adjust your pieces before the glue dries. White glue can also be reapplied after it has dried if necessary.

Consider the Type of Wood

When it comes to woodworking, there are three main types of CA glues – thin, medium, and thick. You need to select the right one based on the type of wood you will be working with.

Thin CA glue is perfect for woods that are delicate and porous. It penetrates the surface easily and bonds quickly.

Medium CA glue is ideal for woods that are slightly more dense than porou such as maple or cherry. It still penetrates the surface easily, but takes a little longer to bond than thin CA glue.

Thick CA glue is perfect for hardwoods like oak or mahogany. It doesn’t penetrate the surface as easily as the other two types, but it creates a stronger bond.

Applying CA Glue

There are many different types of CA glue, but not all of them are created equal. You want to make sure you’re using the best CA glue for woodworking to get the job done right. In this article, we’ll discuss the different types of CA glue and what each one is best for.

Surface Preparation

Before applying CA glue, it is important to prepare the surface of the wood. The surface should be clean and free of any dirt, dust, or debris. Any irregularities on the surface of the wood can cause the CA glue to not adhere correctly. Once the surface is prepared, you are ready to apply the CA glue.

Applying the Glue

Now that you have everything you need, it’s time to get started. The first step is to prepare your surface. You’ll want to make sure that the area you’re working in is clean and free of any debris. If you’re working with wood, sand the surface until it is smooth. Once your surface is prepared, it’s time to apply the glue.

There are a few different methods you can use to apply CA glue. The most common is to use a small brush or cotton swab. Dip your brush or swab into the glue and then apply it to the surface you’re working with. Another option is to use an applicator bottle. These bottles have a small tip that allows you to control the flow of glue. Simply squeeze the bottle and the glue will flow out through the tip.

Once you have applied the glue, it’s important to allow it to set for a few seconds before moving on. This will give the glue time to bond with the surface. If you try to move too soon, you risk dislodging the bond and causing your repair to fail.

Curing CA Glue

Cyanoacrylate glue, also known as CA glue or super glue, is one of the strongest adhesives available. It’s also one of the most useful tools in a woodworker’s arsenal. CA glue can be used to bond wood, metal, glass, and most plastics.

CA glue is available in different viscosities, or thicknesses. Thick CA glue is best for bonding larger surfaces and gaps, while thin CA glue is better for Precision applications and tight joints. Thin CA glue will also cure faster than thick CA glue.

The type of CA glue you use will also depend on the substrate you’re working with. Woodworking adhesives are available in different formulations for different woods. Some are even formulated for specific tasks like bonding veneer or repairing furniture.

Once you’ve selected the right CA glue for your project, it’s important to know how to properly apply it. Here are a few tips:

-Start by roughening the surfaces you want to bond with sandpaper. This will help the CA glue to “key” into the surface and create a stronger bond.
-Apply a small amount of CA glue to one surface and spread it evenly with a toothpick or other sharp object.
-Immediately bring the two surfaces together and hold them in place until the glue sets (usually just a few seconds).
-If you need to remove excess CA glue from your project, acetone nail polish remover will dissolve it quickly. You can also use sandpaper to buff it away once it’s dry.


There is no one-size-fits-all answer to this question, as the best CA glue for woodworking will vary depending on the specific project and materials involved. However, some general tips to keep in mind when choosing a CA glue include considering the type of joint being made, the strength of the adhesive needed, and the drying time required. Ultimately, the best CA glue for woodworking is the one that best meets the needs of the specific project at hand.
