How Do You Make Wood Soft and Bendable?
There’re several ways of softening wood for bending. Each method is efficient and useful if you follow the correct procedure.
Otherwise, the wood may tend to split or crack during the softening process.
Here are the best 5 methods to soften wood for bending.
- Soaking in boiling water
- Making kerf cuts
- Spraying alcohol
- Spraying chemicals
So, let’s discuss each of the above methods one by one with the pros and cons of each method to identify which method suits you perfectly to make the wood soft and bendable.
1. How To Soften Wood for Bending with Water
Soaking wood in boiling water is the most popular method of softening wood for bending.
First of all, you need to find a pot with enough space to fit your wood. Then fill it with water as much as possible and heat it to boiling temperature.
Then place wood inside the boiling hot water carefully and let the process begins. Large wood pieces need more time to soften with boiling water.
Boiling water will go inside the wood fiber and make the fiber cells saturated. Water will soak the wood fibers and make them soft and flexible.
This will make the wood wet from both inside and outside.
You must be really careful with this method. Because, if you cannot boil water after filling up the pot, you may have to boil water somewhere else and add it to the pot when it’s boiling.
It could splash or overflow the pot and can get in contact with your skin. Therefore, wear gloves and find a way to boil water when they’re already inside the pot.
Plus, hot water can damage the inside structure of the wood. for example, hot water can cause discoloration of the wood.
Therefore, if you are concerned about the color of the wood, I do not recommend softening the wood with boiling water.
If the wood is not straight-grained, never use boiling water to soften them. Because you’ll probably end up with cracked or splintered wood.
People still like to use boiling water to soften wood for bending because it doesn’t cause to loss of the wood shape.
Keeping a steady shape is so important in wood bending.
In conclusion, here’re some pros and cons of softening wood for bending with water,
Pros And Cons of Using Water to Soften Wood For Bending
|Doesn’t lose wood shape||Change the wood color|
|Make the wood flexible||If the wood is not straight grain|
|Process is easy||Wood can be cracked or broken|
|Soften wood from both inside and outside||Not good for expensive woods|
So, let’s look for another one of the best methods to soften wood for bending by making kerf cuts.
2. How To Soften Wood for Bending with Kerf Cuts
You can soften wood for bending by making multiple cuts on the back of the wood which is also known as the kerf cutting method.
Kerf cutting is one of the most effective ways of softening wood without having any drawbacks to the boiling water method like discolorations of the wood.
Kerf cutting needs no soaking or steaming. Make multiple cuts on the back of the wood with an electric saw.
Those multiple cuts make the wood soften and ready for bending.
Kerf cutting makes the wood flexible to bend.
Too thick wood and large wood pieces can be softened by the kerf-cutting method which does not damage the wood’s interior and exterior structure.
Any kind of wood can be softened by the kerf-cutting method. Including manufactured wood and particle boards.
Try to make kerf cuts perpendicular to the kerfs. But if you cannot cut kerfs perpendicular that’s totally fine. Bending wood parallel is also possible with kerf cuts.
Make sure to bend the wood slow as possible after you soften the wood after kerf cutting. If you the bending faster the wood may likely be cracked.
Therefore, bend carefully with more focus to avoid cracking.
In conclusion, here’re some pros and cons of softening wood for bending with Kerf cuts,
Pros And Cons of Making Kerf Cuts to Soften Wood for Bending
|Doesn’t lose wood shape||Need radial saw or miter saw|
|Make the wood flexible||Multiple cuts can damage the wood|
|Doesn’t change the wood color||Wood can be cracked or break and should bend slowly|
|Able to soften any kind of wood|
|No soaking is needed|
|Able to soften thick and large wood pieces|
|No waiting time|
3. How To Soften Wood for Bending with Steaming
You can soften wood for bending by steaming it with water and it’s popular because it doesn’t change the wood shape during the softening process.
Place the wood pieces in a chamber that’s very hot, steamy, and humid. Then let the softening process happens.
Steaming loosens up the wood fibers and water molecules will go inside the fiber cells and make them saturated. As a result, the wood piece will be softened and flexible.
Overall softening wood with steaming is almost similar to softening wood with boiling water method.
After keeping wood pieces inside the chamber for a long time, take them out and try to bend them quickly.
If they’re still too hard to bend, keep them again in the chamber for any try on another time.
As you noticed in the steaming method, you’ll have to bend the wood quickly as soon as they take out of the chamber.
Yes, that’s true. In the kerf-cutting method, you should do the opposite by bending slowly.
Honestly bending quickly is one of the main drawbacks of the steaming method, because quick bending can cause wood to crack and break.
In conclusion, here’re some pros and cons of softening wood for bending with steaming,
Pros And Cons of Using Steaming to Soften Wood for Bending
|Doesn’t lose wood shape||Need hot, humid chamber|
|Make the wood flexible||Quick bending can damage the wood|
|Doesn’t change the wood color||High waiting time|
|Soften wood from both inside and outside|
4. How To Soften Wood for Bending with Alcohol
Add 50% of alcohol and 50% of water to a container and mix them well. Then pour the solution into the spray bottle and spray all over the wood surface until it softens.
Or you can put denatured alcohol into a spray bottle and do the spraying to soften the wood.
Denatured alcohol contains 94% alcohol which is stronger than the 50-50 alcohol-water solution.
When you’re spraying alcohol, it will soak into the wood fibers and make them saturated. This makes the wood flexible and softens wood internally and externally.
However, make sure to spray prepared alcohol on scrap wood before directly spraying on the main project, because some woods react differently with alcohol.
Scrap wood must need to be from the same wood type as the wood of the main project.
You don’t need to mix alcohol and water if you use straight rubbing alcohol. Because they already have the ideal alcohol-water ratio.
In conclusion, here’re some pros and cons of softening wood for bending with alcohol,
Pros And Cons of Using Alcohol to Soften Wood for Bending
|Doesn’t lose the wood shape||Can damage the wood due to alcohol|
|Make the wood flexible||An experiment is needed before the application|
|Doesn’t change the wood color||Soaking is needed|
|Soften wood from both inside and outside||Over-application can leave wood with watermarks.|
|Less waiting time|
5. How To Soften Wood for Bending with Chemicals
Spray wood with chemical agents to soften wood for bending. Ammonia-based treatment is good to use as a chemical to soften the wood.
Or you can use ammonia gas to soften the wood. ammonia gas acts as steam. It soaks the wood fibers and makes them flexible and bendable.
Other than that, you can use WD-40 to soften the wood. Spray WD-40 all over the wood surface and make the wood fibers saturated.
This will eventually soften the wood. Better to spray WD-40 the day before bending the wood to get the best results.
Make sure to soften wood for bending with chemicals in a well-ventilated area. Because they’ve harsh chemical agents.
Like the alcohol method, test the project with scrap wood before heading into the main project.
In conclusion, here’re some pros and cons of softening wood for bending with chemicals,
Pros And Cons of Using Chemicals to Soften Wood for Bending
|Doesn’t lose wood shape||Can damage the wood due to chemicals|
|Make the wood flexible||An experiment is needed before the application|
|Soften wood from both inside and outside|
|No waiting time|
Tips For Softening Wood For Bending
You’ve already discovered the various methods to soften wood for bending, like soaking in boiling water, making kerf cuts, steaming, spraying alcohol, and using chemicals.
But what if we could add a few extra tricks to your toolbox to help you master this craft?
Let’s dive into some helpful tips for softening wood for bending.
Start with the Right Wood
Selecting the right type of wood is paramount. Not all wood species bend well, and some might even break when you try to bend them.
Air-dried wood, especially oak, has a higher relative moisture content and is typically more responsive to bending methods compared to kiln-dried wood.
Do some research to figure out which wood will best suit your project and bend most effectively.
Pre-soaking the Wood
Before you dive into any hot process like steaming or boiling, pre-soaking the wood is a game-changer.
Why, you ask? It allows the wood to absorb moisture and softens the wood more quickly, preparing it for the bending process.
Leave the wood to soak for at least an hour before you start with the bending procedure.
Use Fabric Softener
You may be surprised, but fabric softener isn’t just for your clothes.
Soaking wood in fabric softener a day in advance can make it even softer and easier to bend. It’s a little trick that many woodworkers swear by!
Keep an Eye on the Wood Grain
Always bend wood according to its grain.
The grain of the wood refers to the direction of the wood fibers or sap of a tree’s trunk.
When you have a solid hardwood board in front of you, you’ll notice horizontal lines indicating the direction of the grain.
Bending wood against the grain can cause it to crack or split, so make sure you’re aware of this before you start.
Work with Ammonia Safely
If you choose to soften wood using ammonia, it’s crucial to follow safety regulations. Ammonia can be harmful if not handled properly.
Always ensure you’re working in a well-ventilated area and use a firmly closed storage container for soaking the wood in ammonia.
Master the Art of Kerf-Cutting
If you’re using the kerf-cutting method to soften wood, remember to maintain equal gaps between cuts—ideally 1.25 cm.
Also, be sure to use a sharp radial or miter saw and proceed with utmost caution, as harsh cuts can cause the wood to crack.
Consider the Thickness of the Wood
The success of your bending technique greatly depends on the thickness of the wood.
If you’re using steam bending, remember this rule of thumb: the wood needs to steam for 30 minutes per inch of thickness.
Practice on Scrap Wood
Before directly applying any softening technique to your main project, consider using some scrap wood first.
This gives you the opportunity to experiment and see how different types of wood react to various softening and bending techniques.
How Long Does It Take Wood to Soften and Bend?
The average take that takes wood to soften and bend is around 1 – 3 hours. But this can vary according to the wood type and the method you follow to soften the wood.
If the wood is fresh and raw, it typically takes a long time to soften.
Patience is the key to softening and bending the wood perfectly without cracking or breaking the wood.
That’s it, folks! Now you know how to soften wood for bending using the most simple and accurate methods with all the useful tips.
Do you know there is one alternative method to soften wood? Yes, there is. You can use Vinegar to soften the wood. Let’s see how it’s done.
Can You Use Vinegar To Soften Wood?
Yes, Vinegar help to soften the wood. Vinegar soaks into the wood fibers and makes them saturated. This makes the wood flexible.
You can easily bend any wood using vinegar.
Let’s journey into the realm of woodwork and discover how vinegar can become your ally in softening wood for bending.
The Science Behind the Softening
First things first, let’s understand why vinegar has this softening effect on wood. The magic lies in the acetic acid content of vinegar.
Acetic acid can penetrate the wood fibers, causing them to expand and become pliable.
This, in turn, makes the wood easier to bend without the fear of it cracking or breaking.
How To Soften Wood for Bending Using Vinegar?
Soaking the wood in vinegar is a simple and straightforward method.
All you need is a container big enough to hold the wood, enough vinegar to submerge the wood, and a bit of time.
Here’s the procedure you need to follow when softening wood with vinegar,
- Select Your Vinegar: While any type of vinegar will work, white distilled vinegar is commonly used because it’s cheap and doesn’t stain the wood.
- Soak The Wood: Place your wood in the container and pour in enough vinegar to completely cover it.
- Wait and Watch: Let the wood soak in the vinegar. The duration will depend on the thickness and type of the wood, but typically, a few hours should suffice. For thicker pieces, you may need to soak it overnight.
- Bend the wood: Once the wood is sufficiently softened, remove it from the vinegar and gently bend it to your desired shape. Remember to be careful and patient to avoid breaking the wood.

The Vinegar Spray Technique
If soaking isn’t an option, perhaps due to the size of the wood or your workspace limitations, you can also consider spraying vinegar onto the wood.
Simply fill a spray bottle with vinegar and generously spritz it onto the wood. Let it soak in, and soon, the wood will become more flexible and ready for bending.
While vinegar is a handy wood softener, it’s not without its drawbacks.
For one, it can impart a strong smell to the wood.
Moreover, if not properly dried and treated afterward, it can lead to the wood becoming more susceptible to mold and mildew.
A Final Tip
As always, before you proceed with the actual project, it’s wise to test the vinegar softening method on a scrap piece of wood first.
This will give you a better idea of how long you need to soak or spray the wood, and how the wood responds to the vinegar.
Now you know how to soften real wood for bending. But haven’t you thought to bending manufactured woods like veneer?
Yes, it is possible. But the procedure is somewhat different.
Let’s talk briefly about softening wood veneer for bending
How to Soften Veneer for Bending
The bending veneer can be a bit tricky due to its delicate nature.
However, with the right knowledge and a bit of patience, you can bend it like a pro.
Let’s discuss the procedure of softening the veneer for the bending step-by-step.
Understand the Nature Of Veneer
Before we delve into the tips and tricks, it’s important to understand that veneer is thin, delicate, and requires a gentle approach.
Trying to bend it without proper preparation can result in cracks and breaks.
So, how do we prepare veneer for bending? The key lies in softening it, and here’s how you can do it.
Soaking Veneer in Warm Water
The most basic and arguably simplest method to soften veneer is by soaking it in warm water.
This method works because the warm water relaxes the wood fibers in the veneer, making it more pliable.
Here’s how to soften veneer for bending with warm water: Fill a container with warm water—not boiling, mind you—and immerse the veneer in it.
Let it soak for about 30 minutes. You’ll notice that the veneer becomes more flexible and is now ready to bend.
A word of caution though, handle the softened veneer gently to avoid any damage.
Using a Steam Iron
Another way to soften veneer for bending involves using a common household item—a steam iron.
Yes, the same one you use to press your clothes! The steam from the iron helps to relax the fibers in the veneer, making it more bendable.
First, lay the veneer flat on a heat-resistant surface. Next, set your iron to the steam setting and gently go over the veneer.
Make sure to keep the iron moving to avoid scorching the wood. This process should make the veneer supple and ready to bend.
For those looking for a more professional approach, there are commercial veneer softeners available in the market.
These softeners are specially formulated to penetrate the veneer and relax the wood fibers, making them more flexible.
To use a veneer softener, spray or brush it generously onto the veneer and let it soak in.
After a few minutes, the veneer will become more pliable and ready for bending.
You can also use heat to soften the veneer. This method involves using a heat blanket or heat gun.
The heat relaxes the fibers and makes the veneer more pliable. However, be careful not to overheat the veneer as it can cause damage.
Regardless of the method you choose to soften your veneer, testing on a scrap piece first is a good idea.
Different types of veneer react differently to these softening techniques, so it’s always better to test first to avoid any potential mishaps.
So, let’s answer some frequently asked questions as well.
What types of wood are best for bending?
Air-dried wood, particularly oak, often works well for bending due to its higher relative moisture content. However, the best type of wood can also depend on the softening method you choose.
Is it possible to soften wood using cold water?
Unfortunately, cold water won’t soften wood sufficiently for bending. The lignin in wood requires high temperatures to become pliable, which can be achieved through hot water soaking or steaming.
Are there any risks associated with softening wood using chemicals?
Yes, some chemicals like ammonia can be harmful if not handled properly. It’s crucial to perform such processes in a well-ventilated environment and adhere to all safety regulations.
What are some tips for successful wood bending?
Pre-soaking the wood is a good practice when using hot processes. Also, maintaining an equal gap between kerf cuts, and considering the wood’s thickness can significantly affect the success of your wood bending.
Can I use alcohol to soften wood?
Yes, spraying a 50/50 alcohol-water solution or pure denatured alcohol on the wood can soften it for bending. However, different types of wood may react differently to alcohol, so a test on scrap wood is advisable.
