Air drying lumber is the process of allowing freshly sawn wood to dry naturally over time, with no additional heat or moisture added. For centuries, this technique has been relied upon to create a superior wood product and continues to be a prevalent method in the present day.

The idea behind air drying lumber is simple: by exposing it to the air, excess moisture will evaporate over time until the wood reaches a stable moisture content.

Why it’s Important to Know The Pros and Cons of Air Drying Lumber

Knowing the pros and cons of air drying lumber is crucial for anyone involved in woodworking, from professionals to hobbyists alike. Examine both sides of the equation and assess whether air drying your lumber is the best option for your project.

Gaining a comprehensive understanding of the process grants you the ability to make an informed decision and can save you money while preserving wood’s natural color and texture. Consider any downsides before committing to this method.

Equip yourself with the necessary tools to conquer any obstacles that may arise if you choose to progress with this task. Gain the confidence and assurance needed for successful execution. So let’s take a closer look at both the advantages and disadvantages of air drying lumber in more detail.

The Pros and Cons of Air Drying Lumber

The Pros of Air Drying Lumber

Cost-effectiveness

One of the most significant advantages of air drying timber is its cost-efficiency in comparison to kiln drying. By capitalizing on natural elements such as wind, sunshine, and ventilation, air drying eliminates the need for costly machinery and energy resources required for kiln drying; thus, offering immense economic savings.

By opting to air dry your lumber, you can significantly reduce your expenses compared to sending it to a kiln. In addition, when you air dry your lumber, you can do it in small batches as needed.

This is especially useful for small-scale woodworkers or DIY enthusiasts who don’t need large quantities of dried lumber at once. By air drying your lumber in smaller batches over time, you can also spread out the costs associated with the process, making it even more affordable.

Preservation of Natural Color and Texture

Other advantages of air drying seasoning is that it preserves the natural color and texture of the wood. Subjecting wood to high heat in a kiln can cause noticeable changes in color and texture.

For example, if you’re working with cherry wood which has a beautiful reddish-brown color naturally but when subjected to high temperature turns brown or dark brown losing its natural beauty. By contrast, when you allow wood to dry naturally through exposure to air and sunlight over time (air-drying), its natural attributes are preserved during the process without any alteration to its inherent physical properties.

Reduces Risk Of Warping And Cracking

Air-drying results in less warping and cracking than kiln drying wood because there’s less stress put on the wood fibers during the process. In fact, many experts say that this method actually reduces risk compared with other methods because there’s no sudden change in temperature or humidity that can cause stress on the wood.

Kiln-dried wood is subjected to high temperatures that can cause stress on the wood fibers, resulting in warping or cracking. Air drying works by slowly removing moisture from the wood, which gives the fibers time to adjust gradually without any sudden drastic changes in the environment of the lumber.

Consequently, it reduces the risk of warping and cracking. This allows you to have a much better outcome when working with your chosen lumber for whatever project you have in mind. If you want to start drying your wood without warping, it is recommended to read the tips in my article How to Dry Timber Without Warping: 7 Tips for Perfect Results.

Cons of Air Drying Lumber

Takes longer than kiln drying (up to several years)

One of the major disadvantages of air seasoning lumber is its prolonged process. Depending on the type of wood and environmental conditions, the air drying process can take anywhere from several months to multiple years to complete.

If your project requires a speedy turnaround, air-drying is not the ideal option. Moreover, as the process of air drying is time-consuming, it can be perplexing to tell when the timber is adequately dry for use.

In humid or damp climates, the moisture in the air significantly prolongs the drying process. As such, many woodworkers choose to invest in moisture meters to ensure that their lumber has reached an appropriate moisture level before using it for their projects.
To find the best moisture meter, go to my article Top 5 Best Moisture Meters on the Market: The Ultimate Buying Guide.
If you are searching to buy A pinless moisture meter, check out this buying guide.

Requires proper storage conditions to avoid mold and insect infestation

Another potential downside of air drying lumber is that it requires proper storage conditions throughout the process. If not stored correctly, your lumber could be susceptible to mold growth or insect infestations which can render it unusable.

To safeguard your timber from deterioration, store it in a dry, well-aerated space. Consider applying wax or another protective coating to the ends of the wood to reduce splitting and cracking during drying.
Learn more about wood storage in my article How To Store Dried Lumber To Prevent Reabsorption Of Moisture.

May not achieve desired moisture content for some applications

When selecting air-dried lumber, it is essential to note that the desired moisture content may not always be achieved for various uses. In fact, some woodworkers argue that kiln-dried lumber provides more consistent results because you have greater control over how much moisture is removed from each piece.

Air-dried lumber can be an ideal selection for projects that don’t require stringent moisture control. For optimum preservation of the wood’s natural color and texture, air drying is strongly recommended.

Comparison with other drying methods

To ensure the best possible drying of lumber, there are numerous methods to choose from that offer varying benefits and drawbacks. Here is a comprehensive comparison:

Kiln drying

Kiln drying is a popular method for drying lumber quickly and efficiently. The lumber is placed in a chamber with controlled temperature and humidity levels to promote uniform drying. The advantages of kiln dried lumber are an expedited drying process, minimized chances of insect destruction, and precise control of moisture content. However, kiln drying can be expensive, requiring specialized equipment and energy to operate.

Dehumidification Drying

This method involves using a specialized dehumidifier to remove moisture from the wood. The wood is placed in an enclosed chamber with a dehumidifier, which removes the moisture from the air, causing the wood to dry faster than air drying.

Dehumidification drying is useful for drying wood that is too thick for air drying, or for wood that requires a more precise level of moisture control than air drying can provide.

Factors to consider when choosing air drying lumber

Air-drying lumber can be an economical and efficient way of drying lumber, but it necessitates mindful contemplation of multiple facets. Here are some important factors to consider when choosing air drying lumber:

Climate

The climate where the lumber is being air-dried can have a significant impact on the drying process. In general, air-drying lumber is most effective in areas with low humidity and good air circulation. In humid or rainy climates, it can take longer for the lumber to dry and there is a greater risk of fungal growth, insect damage, and warping. If air-drying lumber in a humid climate, it may be necessary to cover the lumber with a protective layer or to use fans to increase air circulation.

Type of wood

Hardwoods like oak and hickory typically require longer drying periods than softwoods like pine or fir, and each species of wood has unique drying characteristics. Careful selection can ensure the best results for air-drying, maximizing efficiency and quality. Some woods may also be prone to defects or cracking when air-dried, so it is important to research the specific characteristics of the wood being dried.

Available space

Air drying lumber requires a significant amount of space, both for stacking the lumber and for allowing air to circulate around the boards. Depending on the quantity of lumber being dried, this can require a large outdoor space or a specialized drying shed. It is important to consider the available space when planning to air-dry wood and to ensure that the drying area is protected from weather events such as rain or excessive sunlight.

By carefully considering these factors, it is possible to successfully air dry the wood and achieve high-quality results. Close monitoring of the drying process is crucial for avoiding defective wood or damage. For woodworkers and builders, air-drying lumber may require more time and energy than alternative methods, yet it can be a wallet-friendly and environmentally conscious choice.
