How Long Does Wet Wood Take To Dry?

It may seem like such an obvious statement that you should only work with dry wood when making furniture.  Yet, wood can feel dry to the touch while still being wet inside, and your sense of touch will be affected by the moisture content of the air in which you are standing.

But how long is it going to take for your wet wood to dry?  There are several factors that will determine the answer to that question, and that is why we are here today.  Whether it’s wood in the woodworking shop, or wood for the fireplace of wood stove, allowing enough time for the drying process to play out is important.

Key Points:

  • Hardwoods will dry slower than softwoods.
  • Using wet wood for furniture projects can be dangerous, as the furniture piece may crack or warp.
  • There are steps you can take to speed up the wood drying process.

Wet Wood

Wood is hygroscopic. This means that it absorbs and releases moisture from the air. The amount of moisture that wood absorbs or releases depends on the relative humidity of the air. When the relative humidity is high, wood will absorb moisture. When the relative humidity is low, wood will release moisture.

The hygroscopic nature of wood can cause problems. For example, wood that is exposed to high humidity can swell and warp. Wood that is exposed to low humidity can shrink and crack.

There are a few things that can be done to prevent problems caused by the hygroscopic nature of wood. One is to store wood in a cool, dry place. Another is to use a sealant on wood that will be exposed to the elements.

Here are some additional tips for preventing problems caused by the hygroscopic nature of wood:

By following these tips, you can help to prevent problems caused by the hygroscopic nature of wood.

How To Measure Moisture Content In Wood

Wood Moisture Meter

Dry to the touch is one thing; understanding how wet the wood might be inside is another.  It’s a good idea to test the moisture content of the wood you will be working with to determine its suitability for the project.  This would be especially true when making furniture.

There are two main ways to measure wood moisture content:

  • Oven drying. This is the most accurate method, but it is also the most time-consuming. To measure wood moisture content using oven drying, you will need to:
    • Cut a small piece of wood from the area you want to measure.
    • Weigh the piece of wood.
    • Place the piece of wood in an oven set to 220 degrees Fahrenheit (104 degrees Celsius).
    • Bake the wood for 24 hours.
    • Remove the wood from the oven and let it cool to room temperature.
    • Weigh the wood again.
    • The difference in weight between the wet wood and the dry wood is the amount of water that was in the wood.
    • The moisture content of the wood is calculated by dividing the weight of the water by the weight of the wet wood and multiplying by 100.
  • Moisture meter. This is a faster and easier method, but it is not as accurate as oven drying. To measure wood moisture content using a moisture meter, you will need to:
    • Purchase a moisture meter.
    • Turn on the moisture meter and follow the instructions.
    • Insert the probes of the moisture meter into the wood.
    • The moisture meter will display the moisture content of the wood.

The ideal moisture content for wood varies depending on how you intend to use it for your project. For example, You want the wood that will be used for a furniture project to have a moisture content of 8-12%; but wood you intend to use in the fireplace or wood stove should have a moisture content of 20-25%.

It is important to note that wood with a high moisture content is more likely to warp, crack, and rot. It is also more likely to produce creosote when burned.

What Is A Moisture Meter For Wood?

A moisture meter for wood is a device that is used to measure the moisture content of wood. Moisture meters are used by woodworkers, carpenters, and other professionals to ensure that the wood they are working with is dry enough to use. Moisture meters can also be used to identify areas of wet or dry wood, which can be helpful for troubleshooting problems such as warping, cracking, and rotting.

Moisture meters work by measuring the electrical resistance of wood. The electrical resistance of wood is lower when the wood is wet and higher when the wood is dry. Moisture meters use this principle to calculate the moisture content of wood.

You will have two primary types of moisture meters to choose from: pin-type moisture meters and pinless moisture meters. Pin-type moisture meters use two pins inserted into the wood.

The pins measure the electrical resistance of the wood and calculate the moisture content. The other type of meter, a pinless moisture meter, uses electromagnetic waves to measure the moisture content of wood.

Moisture meters are a valuable tool for woodworkers, carpenters, and other professionals. Moisture meters can help to ensure that wood is dry enough to use and can help to identify areas of wet or dry wood. Moisture meters are a relatively inexpensive tool and can be a valuable addition to any woodshop.

Here are some of the benefits of using a moisture meter for wood:

  • Prevents damage to wood. As we have said, wood with a high moisture content is more likely to warp, crack, and rot. Using a moisture meter can help you to identify wet wood and take steps to dry it before it causes damage.
  • Ensures safety. Wood with a high moisture content can produce creosote when burned. Creosote is a dangerous substance that can cause respiratory problems. Using a moisture meter can help you to ensure that your wood is dry enough to burn safely.
  • Improves quality of work. Wood that is dry and properly seasoned will produce better results when used in woodworking projects. Using a moisture meter can help you to ensure that your wood is in good condition before you start working with it.

Why Should You Wait For Wood To Dry When Making Furniture?

When a tree is cut down, the cells in the wood are still full of water. Newly cut and milled wood is called green wood rather than wet wood. As the wood dries, the water evaporates, and the cells shrink. This can cause the wood to warp, crack, and shrink.

Waiting for wood to dry before making furniture is important to ensure that the furniture is stable and will not warp or crack. The amount of time it takes for wood to dry depends on the type of wood, the thickness of the wood, and the climate.

As you might expect, the common types of softwoods we work with, like pine and fir, take less time to dry than hardwoods like oak and maple. Thicker pieces of wood take longer to dry than thinner pieces of wood. Wood will dry more quickly in a warm, dry climate than in a cold, humid climate.

There are a few things you can do to help wood dry more quickly:

  • Stack the wood in a cool, dry place. This will help to slow the rate of moisture absorption or release.
  • Avoid stacking wood in direct sunlight or near heat sources. This can cause the wood to dry too quickly and crack.
  • Turn the wood regularly. This will help to ensure that the wood dries evenly.
  • Monitor the moisture content of the wood. When the moisture content reaches 12% or less, the wood is considered to be dry.

By following these tips, you can help to ensure that your wood dries properly and will last for years to come.

Here are some of the problems that can occur if you use wet wood to make furniture:

  • The furniture may warp or crack.
  • The furniture may not be as strong as it would be if it were made with dry wood.
  • The furniture may not be as durable as it would be if it were made with dry wood.

It is important to wait for wood to dry before making furniture. This will help to ensure that the furniture is stable, strong, and durable.

What Is Moisture Equilibrium?

Moisture equilibrium is the point at which the moisture content of wood stops changing. This happens when the wood has absorbed or released enough moisture to match the moisture content of the surrounding air.

The moisture content of wood is affected by a number of factors, including the type of wood, the thickness of the wood, the climate, and the method of drying.

The type of wood affects the moisture content because different types of wood have different densities. Denser woods, such as oak and maple, tend to have a lower moisture content than less dense woods, such as pine and fir.

The thickness of the wood also affects the moisture content. Thicker pieces of wood take longer to dry than thinner pieces of wood.

The climate also affects the moisture content of wood. Wood will dry more quickly in a warm, dry climate than in a cold, humid climate.

The method of drying also affects the moisture content of wood. Air-dried wood typically has a higher moisture content than kiln-dried wood.

Moisture equilibrium is important for wood because it helps to prevent the wood from warping, cracking, and rotting. When wood is not at moisture equilibrium, it can absorb or release moisture, which can cause it to change shape.

So How Long To Wait For Wood To Dry and Reach Moisture Equilibrium?

Wood Planks Drying

The time it takes for wet wood to dry depends on a number of factors, including the type of wood, the thickness of the wood, the climate, and the method of drying.

In general, it takes about one year per inch of thickness for wood to dry naturally. So, a 2-inch thick log would take two years to dry. However, this is just a general rule of thumb, and the actual drying time can vary depending on the factors mentioned above.

Hardwoods typically take longer to dry than softwoods. This is because hardwoods have a higher density and contain more resins, which can slow the drying process.

The climate also plays a role in the drying time. Wood will dry more quickly in a warm, dry climate than in a cold, humid climate.

There are a number of ways to speed up the drying process, such as using a kiln or a solar dryer. However, these methods can be expensive and may not be practical for everyone.

The best way to dry wood is to simply stack it outdoors in a well-ventilated area. You want plenty of air circulation all around the wood, so stack it with This will allow the wood to dry naturally and evenly.

Here are some tips for drying wood:

  • Cut the wood into smaller pieces and split the wood if it’s for the fireplace or wood stove.  Split wood will increase the wood surface area, which will allow it to dry more quickly.
  • Stack the wood in a well-ventilated area and use blocks or strapping to separate layers of the wood to allow for greater air circulation. This will help to prevent the wood from rot and mold growth. Both rot and mold growth will require removal from the wood before it is ready to be used.
  • Cover the wood with a tarp or other waterproof material to protect it from rain.
  • Turn the wood every few weeks to help it dry evenly.

With proper care, wood can be dried in a few months. However, it is important to be patient and allow the wood to dry completely before using it. Burning wet wood can produce creosote, which is a dangerous substance that can cause respiratory problems.

What Wood Takes Longer To Dry Than Others?

We’ve already noted that hardwoods take longer to dry than softwoods.  But specifically, which woods do take longer to dry than others?

The following wood species take longer to dry than others:

  • Oak
  • Maple
  • Ash
  • Walnut
  • Cherry
  • Mahogany
  • Ebony
  • Rosewood
  • Teak

These wood species are all hardwoods which means that they have a higher density and contain more resins than softwoods. The higher density and resin content of hardwoods make them more difficult to dry.

The wood’s thickness will increase the drying time, too. The thicker the wood, the longer it will take to dry, which is kind of obvious and intuitive.

The climate also plays a role in the drying time. Wood will dry more quickly in a warm, dry climate than in a cold, humid climate.

It is important to allow wood to dry completely before using it. If you are drying wood for your fireplace or wood stove, remember that burning wet firewood can produce creosote, which is a dangerous substance that can cause respiratory problems.

We refer to wood that is dry enough for burning as seasoned wood to contrast it from green wood.  Seasoned firewood will give you a better burn with less creosote being produced.  

Factors Affecting Wood Drying Times

Green Wood

The time it takes for wood to dry depends on a number of factors, some of which we have already identified, although there are others, including:

  • Type. As we’ve stated, wood species impacts drying time – hardwoods typically take longer to dry than softwoods. This is because hardwoods have a higher density and contain more resins, which can slow the drying process.
  • Thickness. Thicker wood will be longer to dry.
  • Climate. Wood will dry more quickly in a warm, dry climate than in a cold, humid climate.
  • Method. There are a number of ways to dry wood, including air drying, kiln drying, and solar drying. Air drying is the most common method, but it can take several months for the wood to dry completely. Kiln drying is a faster method, but it can be more expensive. Solar drying is a relatively new method that uses the sun’s heat to dry wood. It is a sustainable method of drying wood, but it can be slow, depending on the climate.
  • Season. Wood dries more quickly in the spring and summer than in the fall and winter.
  • Moisture content. Obviously, the higher the humidity level, the longer the drying process.
  • Airflow. Good airflow is essential for drying wood. If the wood is not allowed to dry properly, it can warp, crack, or rot.
  • Temperature. The higher the temperature, the faster the wood will dry. However, it is important to avoid drying wood at too high of a temperature, as this can damage the wood.
  • Relative humidity. The lower the relative humidity, the faster the wood will reach moisture equilibrium and dry. However, it is important to avoid drying wood in a very dry environment, as this can cause the wood to shrink and crack.

How To Speed Up Drying Time For Wood 

We’ve mentioned several ways to speed up drying time, but there are a few other steps you can take to move the drying process along with wood:

  • Use a dehumidifier to help reduce the humidity level in the air. This will help the wood to dry more quickly.
  • Install a fan in the area where you are drying the wood. This will help to circulate the air and promote drying.
  • Avoid placing the wood near heat sources, such as a furnace or fireplace. This can cause the wood to dry too quickly and crack.
  • Check the wood regularly for signs of rot or mold growth. If you see any signs of damage, remove the wood from the drying area and discard it.

By following these tips, you can help to ensure that your wood dries properly and evenly.

Here are some methods that can speed up the drying process, but they can be expensive and may not be practical for everyone:

  • Kiln drying. Kiln drying is a process of drying wood in a controlled environment. This method can dry wood in a matter of weeks, but it can be expensive.
  • Solar drying. Solar drying is a process of drying wood using the sun’s heat. This method is more sustainable than kiln drying, but it can be slow, depending on the climate and weather conditions. Warm air holds more moisture, and when humidity levels rise, so does the moisture absorbed by wood.

It is important to note that drying wood too quickly can cause the wood to warp, crack, and split. It is important to dry the wood at a safe rate to ensure that it is safe to use.

We could always bury wet wood in a desiccant of some kind – we do that when our cell phone gets wet, putting it in a bowl with rice to draw out the moisture.  We’re only joking here, of course, as the cost of any desiccant would make its use as a wood drying agent too expensive.

Can You Stain Wet Wood?

No, you should not stain wet wood. The stain will not adhere properly to the wood and will likely peel or fade over time. It is important to allow the wood to dry completely before staining it.

Can You Paint Wet Wood?

No, you should not paint wet wood. The paint will not adhere properly to the wood and will likely peel or fade over time. It is important to allow the wood to dry completely before painting it.

Here are some of the problems that can occur if you paint wet wood:

  • The paint will not adhere properly to the wood and will likely peel or fade over time.
  • The paint may bubble or blister.
  • The paint may not dry evenly.
  • The paint may not be as durable as it would be if it were applied to dry wood.

It is important to allow the wood to dry completely before painting it. This will help to ensure that the paint adheres properly and that the finished product is of the highest quality.

Patience, woodworkers, and wood burners.

Let the wood dry fully before using it in woodworking projects and in the fireplace; 12% moisture level for woodworking and 20% – 25% for fireplace wood.
