How to Dry Pressure Treated Wood

Preserving wood is a widespread technique that is used worldwide. It is usually done for wood that is often at the mercy of decay. Therefore, it is pressure treated to preserve its biochemical structure. You will find that the science behind this works as the chemicals penetrate the wood cells to force them into concentration. 

It will then become a fortress against organisms that specialize in decay. The chemicals will also have a powerful smell that will hinder any termites from entering the wood. Once the chemical side of the treatment is complete, the process continues as the wood needs to be dried. 

Drying the wood will take its moisture content limit right down to the lowest levels. What was usually a 100% moisture content limit will now turn to around 19%. This means that you will be experiencing benefits as a business that comes in reduced construction time. 

This is because you can perform this process in any weather; therefore, construction can occur 24/7. Reduced overall construction time also has a sub advantage of having to pay employees less. 

How to dry pressure treated wood 

If you are trying to figure out a way to dry pressure-treated wood, I can suggest two options. 

The first is to use a homemade wood kiln to speed up the process and achieve a 100% sealed piece of wood. This method is well known to provide users with a significantly faster method of drying wood. Usually, taking about eight months to a year to dry will only take two to three days. 

The second option that you can consider is to let it dry naturally. This option is not highly recommended because many people will notice excessive shrinking due to the lack of chemical preservatives used in this process. 

It is, therefore, best that you make sure that none of the wood you have is drying naturally; otherwise, it is easily exposed to termites. This exposure can lead to holes and gaping deficiencies in the structural integrity of the wood that you use. 

How to dry pressure treated wood with a kiln

This is a highly durable option for people who want to use wood to beat all the weather elements. This method works hard to ensure that there is quite a significant reduction in the shrinking and warping factors that often make their way into the drying process. 

Drying wood in this fashion will allow you to stain and seal it once it is completely done quickly. It is, therefore, prevalent amongst people who want to begin wood carving. This is because the wood becomes extremely easy to cut. 

Many people will tell you that it provides a lifetime guarantee that states you would be protected when termites and decay. The benefits of this procedure include having improved compatibility in terms of different steels that you can use. 

You will most likely notice that the dimensional stability soars through the roof combined with aluminum and carbon steel. It becomes a much lighter weight that you will be easily able to handle when it is time for you to install and use this wood. Without using this process, you would find that it takes around eight months to dry a piece of green timber. 

The process to do this is.

  1. The first thing you will be expected to do is get the wood and put it in a large steel cylinder. This is often referred to as a vacuum pressure vessel or tank and will be the main machine used to suck out the moisture from the wood. 
  1. The second thing you will need to do is ensure that the pressure tank is 100% sealed. This is a crucial step because if the tank is not adequately sealed, you may ripping apart the wood piece. 
  1. Once you have fully sealed the pressure tank, the next stage will be to extract all the oxygen within the chamber. Usually, you would make use of an industrial vacuum pump, which would ferociously remove all the air that exists within this tank. Bear in mind that the oxygen will not just be coming from around the wood but from inside the wood. This is how the air content limit of the piece of wood goes down from 100% to around 19%. 
  1. Once we have fully decreased the piece of wood’s air content limit, we must begin the preservation process. At this point, you will fill the tank with a preservative solution. The solution will be a combination of several things, mainly including water and insect repellent. Bear in mind that it is vital that the tank is complete and the wood is submerged totally. If you leave out any spaces, this is a potential area where air can begin to penetrate the wood. Using the method in this manner will ensure that this would be sealed for a lifetime. 
  1. The fourth part of this process is for you to apply pressure to the solution then. When you apply pressure to the solution, you will find that it penetrates the Woods oxygen holes and seals them entirely. Therefore, this form of sealing is well recognized worldwide. 
  1. The final stage of this is now to put a depressurized piece of wood in the Kiln. This is an airflow device that will provide you with sufficient airflow that will allow the moisture reduction to come down to 80%. 

Things to note.

It is essential that once this process has been conducted, you begin to drain the tank. Draining the tank will allow you to entirely remove any additional preservatives that remained while the drying process was being executed. 

It is also important to note that once you have completed this entire process, it is essential that you wait at least one or two days before you can begin operating with this would. This is just a safety precaution to allow you to have the best quality when you begin. 

Use a moisture meter

Remember when reading the previous section that this process will take a significant amount of time.

You must also remember that the wood piece will have a moisture content of around 25 to 30% after dried as usual. To begin with, you must decide how you will use the piece which is in question.

To begin with, you must target how heavy and sturdy the piece of wood is since we are dealing with weight, density, and hardness.

Apply a sealer

Because the final stage of this process involves applying a sealant, you must apply it correctly.

The most important part for you to remember is the application of a wood sealer. This is because these sealers are used to protect wood pieces before using them in any structure.

Therefore, you must use a quality sealer that will fully protect the piece from any contamination or damage throughout its lifetime.

Apply a water repellent

The next thing to remember is that you must apply a water repellent. This ensures that this piece of wood will not get wet, and it will provide better resistance to decay and staining over time.

Remember, you must use a quality water repellent since its purpose is to help maintain the quality of your wood piece.

Allow drying

Once you have applied the sealer and the water repellent, you must allow the sealer to dry.

Before starting to use your wood piece, make sure that you have allowed it to dry for a longer period of time. This will give you a better guarantee that you will completely protect your wood pieces from any damage.

The finish, commonly used when finishing wooden products, is known as an oil finish or a Danish oil finish.
