In this post, we will take you through the different types of wood glue available, tips on how to choose the right wood glue for your task, and some of our favorite wood glues for every budget and the classic DIY tasks involving wood glue.

What are the different types of wood glue?

If you are new to working with wood, then you might be surprised to know that as well as needing a specific glue for this material, there is also a range of different glue types that should be used with wood depending on the task you are doing and the specific type of wood you are using. Here, we will outline the 5 most important types of glue suitable for use with wood and when you should use them.

#1 Cyanoacrylate (CA) Wood Glue

Otherwise known as superglue (or sometimes even crazy glue!), CA is usually the glue of choice for quick repairs thanks to its quick drying time and ability to bond hard materials, including wood, together. Once dry, superglue forms into a plastic like substance, but when applied it is usually a bit runny or sticky. The bonds made with superglue are very hard and rigid and best used for temporary bonds.

Because of its runniness, combined with its super strength, you need to be careful when working with this type of glue as it’s easy to get it on your fingers and skin where it bonds very quickly and is difficult to remove. However, some CA glues come in the form of a gel which remains in place better. You should wear a mask when working with superglue and gloves if possible.

Top tip: If you do get superglue on your fingers, you can use a nail file to remove it or nail polish remover if you have any.

#2 Polyvinyl Acetate (PVA) Glue

Whilst the well-known PVA glue is often associated with arts and crafts style projects, there are actually a range of PVA glues that are suitable for use with wood. Some of these are only suitable for indoor use but stronger variants are also available for outdoor projects. PVA makes permanent bonds that are flexible.

The major benefit of PVA is that is non-toxic and tends to have a modest initial level of tack enabling you to manoeuvre whatever it is you are sticking together at first to make sure it is perfectly positioned. Whilst still wet, PVA is also easy to clean. PVA does show up on wood as a glue patch, but can be easily sanded off.

Top tip: Don’t use PVA glue on joints that you may need to repair in the future as new glue does not stick well to old glue.

#3 Epoxy Glue

Epoxy glue is made up of a resinous part and a hardening material and is a great choice for projects where you need it to fit into the nooks and crannies in the spaces between woods. It can be used for both softwood and hardwoods but can be slower to bond than other glues meaning you should use a clamping system to ensure you get a good bond as the glue dries. Epoxy glue is usually resistant to rain and weather as well as UV rays and heat making it suitable for use outdoors. However, some epoxy glue can only be used indoors so make sure to check this is not the case if you want to use it for an outdoor project.

Top tip: This is a good choice of glue to use to fill in gaps or strengthen damaged wood.

#4 Polyurethane Wood Glue

This is one of the strongest wood glues out there that creates tight and some of the longest-lasting bonds. This glue type is also versatile so is a good choice if you are planning to stick wood to a different type of material, such as plastic, metal, glass, or even concrete. Another benefit of this glue type is that it is waterproof and does not dry in a way that leaves a nasty appearance as PVA does.

The downside of this glue is that it is made from a variety of chemicals so you will need to use mineral spirits to clean it even when wet and be careful not to get it on your skin isocyanates can cause irritation. It is also a good idea to wear a face mask when working with this type of glue.

Top tip: When working with polyurethane glues the surface you apply it to must be made wet first. This makes the glue expand as it sets helping to form stronger bonds.

#5 Hide Glue

Derived from animal collagen (a common protein), this type of glue is one of the oldest known adhesives. As the name suggests, the glue is actually drawn from animal hides. It can be bought in liquid form or in granules which can be melted in a double boiler and applied whilst still warm with a brush. People tend to use this sort of glue when working with antiques to help maintain their authenticity and because it produces a particularly strong bond akin to PVA.

It is also a non-toxic substance, can be stained (unlike PVA), and comes in a number of colors and strengths. The different strengths are measured by gram, with higher grams indicating stronger binding properties. Another benefit of this glue is that it can be used again even once cooled as it can simply be reheated in a double-boiler. This means its effects are reversible which can be very handy when working with wood.

Top tip: This is a great choice of glue for working with furniture and musical instruments.

#6 Hot Melt Glue

Sometimes referred to as HMA (Hot Melt Adhesive), this is the classic glue you remember from school that starts as a cylindrical stick that looks like plastic and gets pushed through a ‘glue gun’ where it is heated and comes out in a sticky, stringy glue. This glue sets very quickly once applied so you need to act fast. It is also only really good on softwoods and is not a strong glue so should not be used on joints although there are some more heavy duty guns out there which increase the effectiveness of this glue type.

Top tip:  This glue can be easily removed by reheating it or can be popped off with a device like a chisel.

How to choose the right wood glue: Top tips

When it comes to choosing the right glue, the key consideration will always be the specific task you are using it for. However, in addition to this major decision, there are a number of other important choices to be made. Here, we outline 8 other key considerations you’ll want to think about when choosing which glue type to use.

#1 Chemical vs non-toxic

Sometimes it is easy to assume that a chemical option will naturally be stronger. However, some non-toxic glues can be just as stronger as their chemical competitors and have the added benefit of being more eco-friendly, being suitable for use in enclosed spaces, and being easier to clean or sometimes even reuse. As such, if you can afford it, a non-toxic glue is usually a better choice if it offers equal bonding strength to a chemical competitor.

#2 Color: Yellow glue vs White glue

If you are looking for a waterproof glue, then yellow glue will usually be a bad option due to the fact that it is not normally waterproof. However, yellow glue tends to be cheaper and can be easily sanded down so if it is not going to be used outdoors or somewhere where it is going to be seen, then it can be a good choice. Yellow glues also tend to have a stronger bond, requires clamping for 30 minutes, and will take between 12-18 hours to cure.

White glue is less heat-resistant than yellow glue and takes longer to dry, although once it has dried it is usually waterproof. The other good thing about white glue is that whilst it is still wet you can clean it up with water whereas yellow glue requires nail polish remover or other harsher chemicals.

#3 Adhesive strength

When working with glue you sometimes need to be able to maneuver what you are sticking together into place requiring an adhesive that does not dry almost immediately on contact, such as super glue. Other times you want to be able to stick something straight on without having to clamp it in place in order for the glue to take effect, as you would be required to do with a yellow glue. Make sure you pick the right adhesive strength for the task you are carrying out and remember that more rigid bonds are likely to break sooner than more flexible ones.

#4 Viscosity

Viscosity is just a fancy way of saying how liquid a glue’s consistency is. Where a glue has low viscosity, this means they are likely to be runnier. Low viscosity glues are suitable for filling in cracks, furniture repairs, and fixing joints in place. Low viscosity glues also tend to have faster drying times.

Medium viscosity glues may be more gel-like in consistency and are a good choice when binding wood with soft or lightweight materials, such as leather, felt, or fiberglass. High viscosity glues are, obviously, thicker and less runny making them suitable for tasks which are more heavy-duty. High viscosity glues are good for bonding wood together with other heavy materials.

#5 Shrinkage

Glues that are more evaporative have a tendency to shrink more than less evaporative glues. So if you want to really fill up a gap and form a really tight joint, then you don’t want to use a glue that is overly evaporative.

#6 Water resistance

Obviously, if you are building something for indoor use this is not likely to be of huge importance. However, if you are working on something that is going to be used outside, then you are going to want something that is highly water-resistant or preferably waterproof. Not all glues are waterproof even when dry, so it is important to keep this in mind.

#7 Drying speed

This links with adhesive strength. If you want a glue that dries almost instantly on contact with limited to no need for clamping, then this is a key consideration.

#8 Stainability

Even if glue dries clear, it can leave an unsightly mark and be obvious that a repair has been carried out. Stainable glue can help with this as the more stainable a glue is, the easier it for it to be painted over or stained to cover up its existence and help give a tidier and neater appearance.

How to use wood glue

Once you have bought wood glue, you usually have up to a year to use them before they start to deteriorate in quality. You should also make sure to clear the nozzle from residual glue after using it if you don’t want to come back to your glue and find the nozzle to be impenetrable and unusable. It is generally a good idea to wear gloves when working with glue, but this should be especially adhered to when working with toxic glues. The same is true for face masks and, ideally, you should work with chemical glues in a well-ventilated space.
