A wooden joint can be connected using screws, nails, or butt joints. But all these require wood glue to strengthen the bond.
As such, wood glue is ideal for joining two pieces of lumber together seamlessly and keeping them tightly bound for decades.
Unless you give the wood glue enough time to totally dry as well as cure. If not the joint would not be as strong as it should be, and will end loosened up.
That’s why it’s essential to give proper time to dry. Nevertheless, how do you determine the optimal drying time for wood glue?
Our topic today covers how long wood glue takes to dry, as well as talk about some things that can speed up the drying time.
The ideal drying time of most wood glues.
The fact is drying time of wood depends on other factors like types of wood, types of wood glue, and how you glue two pieces matters a lot, also the environment can make a difference here.
When keeping factors standard.
The general rule of thumb says after gluing two clamps of wood pieces together you should let them dry for at least 24 hours to get the best results.
Nonetheless, drying takes only 30-60 minutes and many wood glues even dry faster than this.
But it’s the curing time that takes longer. Therefore waiting a day is the best time period regardless of the glue you use.
Summary- After gluing two pieces of wood let them attach for at least 30-60 minutes, make sure the applied wood has been dried thoroughly. By touching it you can verify that.
Once you feel rough, you can now remove the force applied. The joints should be able to hold each other for now so you don’t need to put force anymore.
Wait for 24 hours so the glue will totally soak up between the two surfaces before you use it.
A comparison of drying time
The fact is there are many types of wood glues therefore it’s hard to tell which one has the faster drying time.
The below table compares drying and curing times of the most common woods that are based on the standard temperature and application.
|Type of wood glue||Drying time||Curing time|
|Cyanoacrylate glue||10-15 minutes||5-6 hours|
|Epoxy||4-6 hours||More than 24 hours|
|Polyurethane wood glue||1-2 hours||Maximum 24 hours|
|Polyvinyl Acetate Adhesive||1 hours maximum||12 hours minimum|
Types of wood glues and their drying time.
From the long list of wood glues, it’s quite a headache to choose the right one. In terms of drying time, it is even more difficult.
The following are some common types of wood glues and their drying times, pick the one that best suits your needs.
Polyvinyl acetate (PVA) wood glues,
At standard temperature and applications, polyvinyl acetate glue takes 30 minutes to dry, and it takes 24-48 hours to cure.
It’s the most common type of wood glue, easy to use, viscous, durable and its general-purpose glue can be used for plenty of projects.
Polyurethane wood glues
The drying time of Polyurethane wood glue is 2 hours and it’s recommended to keep the project untouched for 36 hours minimum.
It’s a little less dense than PVA glue used in joining small wooden, plastic, filling narrow gaps of other cracked pieces together. It’s good and can easily get deep.
Epoxy wood glues
The drying time of epoxy glues is 5-6 hours and takes 48 hours to cure fully.
Epoxy Wood glue is the thickest and retains its strength even when exposed to water. The material is mainly used to fill cracks in boats, as well as for joining other projects.
Note that: It is not recommended to use this type of wood in cold and humid weather since it takes a long time to dry.
Cyanoacrylate wood glue
Cyanoacrylate wood glues take 5 minutes to dry but the curing process might take 5 to 6 hours.
This type of wood is usually well-known as super glue. A watery liquid that evaporates in a matter of seconds. In simple terms, it is the quickest wood glue you can pick. Mostly it’s used for small repairs and joining two pieces of wood blocks, plastic, as well other crockery items.
on plastic, how long does wood glue take to dry?
Depending upon which type of wood glue you’re applying, alters the drying process.
Nonetheless, many wood types of glue don’t work on plastic like epoxy for example which is viscous. Plastics are not good absorbing materials because their surface isn’t open to hold any dense substance.
Speaking of the drying time on plastic it’s better to use cyanoacrylate glue (super glue) that has a faster drying time and is watery.
It takes anywhere from 20-30 minutes to fully cure the glue if the surface is small like a filling crack.
on paper, how long does wood glue take to dry?
On paper, the PVA wood glue will work just fine, make sure you don’t put too much on the surface otherwise it will probably not make a good bond.
PVA glues on paper take anywhere between 20 minutes to dry and the curing time is not longer than 2 hours unless you keep the project outside in cold and humid weather.
How long does PVA wood glue take to dry?
The thickness of the glue, the conditions outside, and the materials being glued together would determine the drying time of a PVA wood glue. In simple terms, it’s a variable to say anything certain on that.
You can keep in mind the following things to guess the timing.
If you put too much glue means if it looks thick then the longer the drying time will be. Conversely, the humidity level should be between %30 to %45, and the work area should be ventilated and the temperature should be more than 15 centigrade for quicker results.
How long does Evo Stik wood glue take to dry?
Evo Stik wood glue can be called a hybrid of PVA glue and cyanoacrylate glue.
It’s slightly denser than the superglue and less dense than PVA. Mostly it’s used for jointing concrete materials, wood materials as well plastic materials.
It takes 15-30 minutes to fully dry since it contains some powerful evaporative chemicals.
Which is the best wood glue with a faster drying time?
Titebond No-Run glue
There are so many good wood glues out there, I cannot name every one of them.
However, if you can get this Titebond N-Run glue it’s one the fastest-drying glue I’ve used so far in my projects that require jointing and bonding.
If you need a professional-strength wood glue for finishing trim and crown molding, baseboards, window casings, etc., consider no-run wood glue.
Don’t apply too much glue- it alters drying time
If you want to get a better bond, you will think that applying too much glue on the surface will make the joint last longer. But that’s not the case.
There are many reasons why you shouldn’t apply too much glue. Out of them, one is related to the drying process.
If you apply excess glue on a wood surface. Even after an hour or two, you feel the top surface has dried. However, the underneath still needs to be dried.
It’s because of the density and the air. The uppermost layer takes in air so dry faster, and the most underneath part takes more time which is important to make a joint.
Thus, not to put too much glue in efforts to make a stronger join.
Furthermore, by applying them onto woods that are soft, they can soften the structure as a result of their readily absorbing qualities. Fibers can be damaged if this is done, making the joint less durable.
Ways to speed up wood glue drying time in cold weather?
Because of the cold and humid weather you have to wait for hours for the glue to dry. To get rid of it, you can speed up the process by following a few practices.
Use an Accelerator spray-
There are some products that can speed up the drying process regardless of the environment.
They work so far well. All it takes is a product which is basically a spray you can buy from your nearby DIY store. Spray the bottle on the surface and wait for the magic to begin. It can reduce the drying time to 2x times at least.
Use a fast-drying wood glue-
Choosing the right type of wood glue can also speed up the process. For example, there are loads of glues that are designed to dry faster than others, they are called “Super glues.”
Work on a fully Dry surface.
It’s always better to wipe out any droplets from the surface by using a rag. Most of the time there is already water present on the surface, so the applied glue mixes with it and takes additionally more time to cure.
Only apply the required quantity of wood glue.
Make sure you follow the instructions on the glue package closely and only use as much as it states.
It is generally enough to apply a drop of glue over 1 inch (6.5 cm2) for many types of glues. But still reading the instructions given would help a lot.
Factors that affect the drying time of wood glue.
In determining how long it takes for wood glue to dry, there are some factors to consider. It can be your wood glue and environment.
Here are the factors and little details on how they make an impact.
It’s always better to work in a low-humid environment to speed up the drying process.
The glue on your attached wood pieces will dry and cure quickly if the humidity is lower than the average between 30-50%. Thus a faster dying process.
Conversely, when it’s cold and humidity level is something let’s assume it is %70, then both the drying and curing time will be increased. You will need at least 2 hours to wait so the glue can dry and to cure it can take 2 days maximum.
When it comes to gluing and drying time, it is important to take into consideration the surrounding temperature.
In simple terms, wood glue can take longer to dry when the temperature is less than 10 centigrade because in cold weather the evaporated chemical would not vaporize quickly.
While temperature ranging between 20-30 centigrade is the best in regards to drying time. It would only take 30 minutes to dry a wood glue.
With that said, if you speed up the process while working in very cold weather.
Then, you should choose an open well-ventilated area as well as use some sort of heaters in your workspace to make the temperature optimal to work under.
Type of Wood
Types of wood are also an important factor that can alter a drying process.
Basically, two types of woods are common. softwood and hardwood.
Even though this describes their toughness in general, there are limitations to their names. Since there are hardwoods that are softer than many softwoods.
How they act in terms of absorbing wood glue is different.
Softwoods grow quickly, so they have an open structure. Hardwoods do not have this characteristic.
This makes softwoods quickly absorb the glue and compared to hardwoods they’re easy to bond.
On the other hand, Hardwoods are slow growers like oak and walnut and have dense properties. Wood glue takes more time to penetrate.
Dry small areas of glue with a hairdryer.
Hairdryers work just fine if you want to dry some portion of a wood glue quickly. Hover the hairdryer on the surface from a distance to 12-15 inches far. And set it to lower settings since the highest temperature can make the wood glue wet. Nor use the hairdryer continuously for a longer period.
Keep the works place warm-
Turn on the heater and shut all the windows for some time to make sure the room’s temperature is at the optimal level. Now begin with your gluing project to end it sooner than later.
Moreover, you can use an electric blanket to even speed up the process if you have any, lay it down beneath the project needed to be dried faster.
