Wood glue can provide a strong binder when completely dried up. It is very durable and can be easily applied. In addition, it is invisible when completely dried up. However, early career artisans and even professionals may have trouble knowing when it’s completely dry.
Fret not, our seasoned woodworkers have answered what you need to know about wood glue and how long it takes to dry.
Strength of Wood Glue
Wood glue is an adhesive that allows you to bond wood. You can bond wood to itself or other porous materials such as paper and cloth.
The maximum strength depends on the type of glue you’re using. We will elaborate on each glue type later to know which is the best for your project.
Drying vs. Curing vs. Setting Times: Key Differences to Know
Different adhesives have different drying and curing process. It is best to read the product label and follow the instructions carefully. It is also best to understand and differentiate the terms drying and curing.
Drying refers to removing moisture from the adhesive, making it dry to the touch. Furthermore, the joints are secured, and clamps may be removed.
Curing refers to the continuous synthetic reaction, which is also known as the cure time. Once the wood has completely cured, can you proceed to apply a finish that completes the project. Make sure to know when to completely cure wood based on what’s indicated on the packaging.
5 Wood Glue Types and Their Corresponding Drying Times
There are a few things you need to know before joining the pieces for your project. One is to familiarize yourself with the various kinds of glue options available today.
Each one has a different wood glue dry time. If you want to know how long wood glue takes to dry depending on its type, read on below.
Polyvinyl acetate (PVA)
Polyvinyl acetate wood glue or “PVA” is an adhesive that is a recent innovation. PVA glues are considered one of the most popular glues used for wood today. Several examples categorized as PVA include Elmer’s glue, Titebond wood glue, Tek-bond glue, and Gorilla glue.

Polyurethane
Like PVA glue, polyurethane produces a very strong adhesion if applied correctly. It takes frequency and time to adjust when spreading polyurethane glue. It is, however, the wood glue that many woodworkers use for their projects.
Polyurethane glues do not have an excessive moisture content. Furthermore, it cures that’s a result of reaction to moisture. Lastly, you can use polyurethane glue to bond finished pieces together.
Epoxy
Another ideal wood glue for woodworkers is epoxy glue. Epoxy glues comprise of a mixture whereby both two parts are liquid in form. Thus, mixing it is necessary, resulting in a chemical reaction.
Epoxy wood glue is waterproof and known to be an excellent filler. You may also add and mix sawdust to the epoxy to create the perfect wood texture. Furthermore, the longer you allow the epoxy to cure the stringer, the resulting bond.
Cyanoacrylate
Cyanoacrylate wood glues (CA glues) are popularly known as super glue. Some of the more popular and common forms of Cyanoacrylate glues include super glue, which can also work well on wood.
This type of glue tends to be a pricier option than the other glue types. But the best super glues works well on various materials — be it wood, fabric, metal, plastic, etc.
Hide
Hide glue is also known as animal glue [1]. This wood glue has been used for a very long time.
It has been used for traditional woodworking techniques. Liquid hide glue can be made at home if you are feeling adventurous.
Titebond Hide Glue is one of the best options for a hide glue. The synthetic version produces a stronger bond than the natural one.
Common Wood Glue Products in the Market Today
If you ever wonder how long does wood glue take to dry, here is a summary of the top choices in the market for your reference.
Product Name | Drying Time | Best Application |
Gorilla glue (PVA) | Under 24 hours | PVA wood glues take less than a day to fully cure. Do keep the joints clamped in the first thirty minutes.
Then, you may remove the clamps. Most PVA glues cure for at least 18 hours before attempting to work at it again. |
Titebond (Polyurethane wood glue) | 24 hours | Polyurethane glue has one of the longest curing times. Keep the pieces clamped for about 2 hours to dry the polyurethane glue.
This glue dries in approximately 24 hours. |
Epoxy | Under 10 minutes | Using epoxy as a wood glue to finish your project is very beneficial for its strength. It is also a good option for sealing and filling in gaps.
It will only take about 1 to 3 days for epoxy to cure completely. |
Superglue (Cyanoacryolate) | A few seconds | CA glues are known to have excellent holding properties. Furthermore, the clear and cure time is quick, and precision is simpler. It only takes moments to dry 100%. However, it takes approximately about a full day for the CA glue to cure. |
Titebond Hide glue | Half an hour | Clamp the pieces together for at least half an hour to set them in place. It will take approximately 12-24 hours for the hide wood glue to cure. |
Safest Time: 24 Hours
If you want to take the safest route, we highly recommend waiting 24 hours. This is especially recommended if you’re using different types of glue in your projects, whereas tracking each can be time-consuming.
So, a safe option is to allow the pieces to sit for 24 hours. However, if you’re using a clamp to bind pieces, we don’t recommend keeping them bonded for a long time.
Make sure you add the right pressure that will not distort the wood, should you leave them to dry than the recommended time on the instructions.
What Contributes to the Wood Glue’s Drying Time?
Now that you know how long it takes for wood glue to dry, there are contributing factors to their drying time. These can either help make wood glue dry faster or slower.
Knowing these factors will allow you to understand and plan your project better:
Air
Air circulation is also an important factor when drying glue. In the absence of air movement, the glue will have difficulty drawing out much of its moisture and hamper drying. The more air moves, the more it collects water molecules from the adhesive.
Humidity
Humidity can highly affect the drying process of wood glue. Increased ambient humidity will take more time for the wood glue to complete its drying time. water droplets suspended in the air prevent moisture content from leaving the adhesive and thereby preventing drying.
Working in a closed or temperature-regulated area is necessary. This will allow you to eliminate humidity when working on timber pieces and using wood glue.
Moisture and Humidity
Wood moisture content also affect the time for the glue to dry. Porous wood contains water molecules. If timber is freshly milled, it will probably has accumulated more moisture. On the other hand, kiln dried wood will significantly have lesser moisture.
A drier wood will tend to absorb more liquid from the glue. Thus, this separation will let the wood glue dry faster.
Ventilation
When drying the glue, consider working in an open area. You may add a fan to provide natural air movement and airflow as the glue dries up.
Wood Glue Type
Check the glue you will be working with. There are other wood glues such as polyurethane wood glue (e.g. Gorilla Glue), PVA (e.g. Elmer’s White Glue), and resin (e.g. Titebond II) to choose from. Make sure to know different drying times.
Also, make sure to use a new bottle of glue. This assures you that the glue is effective and will dry. Furthermore, the surface and wood type must also be considered. Tropical woods are often known to have more oil compared to other woods, preventing the glue from sticking to them.
Open and Close Assembly
The assembly, whether open or close, can alter the time it takes for the glue to dry. These two assembly types should be considered when working with projects since they can either speed up or slow down the drying process.
Open assembly refers to items and the time you have from when the glue comes out of the bottle until it can no longer be used. Close assembly, however, refers to the time the item has to reposition the bond until you can no longer move it.
Certain types of adhesives are formulated to have more time for manipulation before they dry completely. Other glues, once applied, can immediately dry within seconds and are difficult to work with. Learn which kind of glue has a faster or slower time before working with pieces of wood.
Stressed vs. Unstressed Joints
Some timber pieces and joints are stressed, whereas others are unstressed. Stressed joints refer to when the clamps are allowed 24 hours before removal. The applied pressure will give the glue a longer time to act on the pieces to stay together.
Unstressed joints do not require a lengthy time of clamping. Removing clamps can be done a few hours after the glue is applied to the wood.
Amount Applied or Thickness
The amount of adhesive applied will also affect the drying time. The thicker the glue applied, it will warrant more time for the glue to dry.
If you apply the right amount or layer of adhesive, it will require several hours to dry. A damp cloth can be used to wipe off excess glue.
What Happens If I Don’t Allow the Wood Glue to Dry?
If you don’t allow the glue to dry, you might compromise the overall integrity of the project. Make sure to thoroughly read and follow the recommended time on the product label for the best outcome.
How to Speed Up Wood Glue’s Drying Time
It is good to give the adhesive a natural drying cycle. However, if you are short on time and in a rush, you may need to speed up the time to dry your glue for a project. However, note that speeding the drying time does not lessen the curing time.
You can harness certain factors to your advantage and hasten the wood glue drying times. To help you speed up the drying time of your glue, there are things you can do:
Ventilation
Air circulation can affect the time it takes to dry glue. Adding more air movement, the more it collects water molecules from the glue, thus drying.
Heat
If you add heat, the more liquid is evaporated into the air. Applying more heat to the adhesive will allow it to dry faster.
Using a heat gun, heat lamp, or hair dryer programmed at the lowest, you can begin with moderate heat. Make sure to have a slow and gentle heat application to cover everything. You may also use a space heater.
Hardener
You can utilize this to speed up the time to leave wood glue to dry, especially in most epoxy glues. You may add additional amounts of hardener to the epoxy when mixing. Once the glue is added, the added hardener will help solidify the epoxy.
What to Do If Your Wood Glue Won’t Dry
There may be some factors resulting in your glue refusing to dry. Consider the type of adhesive you use, especially whether these are water based glues or not. Select the best adhesive appropriate for the lumber type you will work on.
You might also need to check the temperature range in the area. Check if the area is too hot or cold, and make the necessary adjustments.
Check your glue if it is new. Expired glue is not as effective as a fresh one. Make sure to invest in the tools necessary for your project.
Top Fast Drying Wood Glues in the Market Today
Titebond Quick and Thick Glue
Titebond suggests clamping unstressed joints between 30-60 minutes. Curing time is recommended for 24 hours. Stressed joints, on the other hand, should be clamped for 24 hours and an additional 24 hours for curing before applying stress.
Titebond II is a good option due to its water-resistant qualities. The excess glue can be wiped off with a damp cloth while it is still wet. Post drying, the adhesive can be removed through scraping and sanding.
Krazy Fast Dry Glue
This adhesive is known to have a quick drying time. Krazy glue takes approximately seconds to minutes to dry, depending on ambient temperature and humidity.
When Should I Sand the Surface After Applying Wood Glue?
Different types of binding material require sufficient curing time before scraping or sanding it off. Make sure to adhere to the curing times of the glue you are using before sanding then, it should be ok.
Are Clamps Needed for Wood Glue?
Clamping pieces when you apply wood glue is critical to achieving a successful drying process. Therefore, clamping is necessary for a few projects, allowing the piece to stick better.
How Long Should You Wait for the Wood Glue to Settle Until Removing the Clamps?
The length of time for clamping and its subsequent removal depends on the joint.
