Introduction to Pressure Treated Wood
If you have ever been involved in a construction project, or if you’re simply a fan of home improvement shows, you may have heard the term “pressure treated wood”. But what wood is pressure treated? Pressure treated wood is timber that has been subjected to a process designed to enhance its natural resistance to decay and insects. This makes it ideal for outdoor projects where durability and longevity are of paramount importance.
The process of pressure treating wood involves placing it inside a closed cylinder, then applying high pressure to force preservatives into the wood. These preservatives safeguard the wood from fungi, insects, and other damaging environmental factors. The result is a robust piece of lumber that can withstand the elements far better than untreated timber. This makes pressure treated wood an excellent choice for decks, fences, and other outdoor structures.
Pressure treated wood comes in a variety of types, depending on the kind of preservative used and the intended application of the treated lumber. For example, some forms of pressure-treated wood are specifically designed to resist termites, while others are more focused on preventing fungal decay. The type required for a specific project will depend on the nature of that project and the environmental conditions it will be exposed to.
It’s worth noting that pressure-treated wood has a distinctive appearance – often greenish or brownish – due to the chemicals used in the treatment process. However, this coloration will fade over time as the wood is exposed to sunlight and weathering. Despite this change in appearance, the protective properties of the treatment will remain intact.
To sum up, when asking ‘what wood is pressure treated’, we’re discussing lumber that has undergone a specialized process to boost its resistance against decay and insect attack. This process improves the durability and lifespan of the wood, making it an excellent choice for outdoor, ground contact, and certain indoor applications where longevity is a key concern.
Process of Pressure Treating Wood
The process begins with understanding exactly ‘what wood is pressure treated’. Pressure-treated wood is essentially timber that has undergone a procedure to make it more resistant to decay, insects, and fungal infection. The process includes infusing the wood with certain chemicals under high pressure that make the wood durable and long-lasting.
Firstly, the wood is placed into a depressurized holding tank where all the air is removed from the wood’s fibers. This step ensures that the chemical solution can deeply penetrate into the core of the wood.
Next, once the air in the tank has been replaced by a vacuum, a preservative solution – usually water-based and copper-containing (known as CCA Copper – Chromium – Arsenic), is introduced into the tank under high pressure. This pressure forces the solution deep into the inner structures of the wood which could not be reached effectively by simple surface application methods.
After an amount of time, depending on the type of wood and its intended use, this pressurized environment is then released. As a result, the solution becomes embedded into the wood fibers, forming a barrier against organisms that cause decay.
Finally, to ensure no excess moisture remains within the wood which could lead to warping or twisting, the treated wood is left to dry out naturally or sometimes kiln-dried before being sold.
In summary, when we ask ‘what wood is pressure treated’, it’s any type of timber that has undergone this chemical treatment process for durability and longevity. Different types of woods can undergo this treatment process including pine, spruce and fir among others. The type of chemical used can also vary depending on regional environmental regulations and specific requirements of usage.
Types of Wood Used for Pressure Treating

How to Identify Pressure Treated Wood
Pressure treated wood is a popular choice for many construction projects due to its durability and resistance against termites, fungi, and other destructive elements. In this blog post, we will be discussing ‘What wood is pressure treated’ as well as how you can identify pressure treated wood.
Pressure treated wood is ordinary wood that has undergone a process where chemicals are forced into the wood under high pressure. These chemicals act as a shield, protecting the wood from rot and insect infestation. The most common types of wood that are pressure treated are softwoods like pine, cedar, and fir. They are widely used for outdoor projects such as decks, fences, and landscaping structures.
Identifying pressure treated wood is not quite as straightforward as identifying other types of processed wood such as plywood or MDF. However, there are certain signs you can look for to help you make an identification.
The first clue is the color. Pressure treated wood often has a greenish or yellowish tint to it. This is due to the chemical preservatives that have been infused into the wood. However, do not solely rely on color since untreated wood can also turn greenish due to algae or mold growth.
The next thing to look for is small slits or holes arranged in a pattern along the surface of the wood. These are typically left by the machine that forces the chemical preservatives into the wood under high pressure.
Another way to identify pressure treated wood is by its end tag. Lumber yards and home improvement stores usually attach a tag onto one end of each piece of lumber they sell. This tag provides information about the type of treatment the piece of wood has undergone.
Remember though that even if a piece of wood has these identification marks, it does not necessarily mean it’s been adequately protected. Over time, exposure to sunlight and weathering can cause the chemical preservatives to break down. Therefore, regular maintenance is required to ensure the longevity of pressure treated wood.
Moreover, it is important to know that pressure treated wood should be handled with caution as it contains toxic chemicals. Always use gloves when handling it and a mask when sawing or sanding it.
In conclusion, while identifying pressure treated wood may require a keen eye and some knowledge, it is an essential skill if you’re planning any woodworking or construction projects. So, the next time you’re looking at a piece of lumber, take a closer look – you might just be looking at pressure treated wood!
Care and Maintenance of Pressure Treated Wood
When it comes to pressure treated wood, it’s paramount to understand its care and maintenance to enjoy its benefits fully. As the name suggests, pressure treated wood undergoes a treatment process that involves placing untreated softwood into enormous cylindrical holding tanks. The wood is then subjected to great pressure and vacuum, infusing it with preservatives that protect it from pest attacks, fungal decay, and harsh environmental conditions.
This brings us to the question, ‘what wood is pressure treated?’ Ideally, various types of softwood such as pine, fir, and spruce can be pressure treated. These woods are commonly used for outdoor structures like decks, fences, and playground equipment because they withstand exposure to weather elements after treatment.
