Understanding the PT Wood Process
If you’ve ever wandered down the lumber aisle of a home improvement store or looked into building an outdoor structure, you’ve likely come across PT wood. So, what is PT wood? PT stands for ‘pressure treated’, which precisely describes how this type of wood is produced. Understanding the PT Wood process can help illuminate why this type of wood is frequently chosen for outdoor projects, from decking to furniture and beyond.
The PT wood process begins with softwood—pine, spruce, or fir—that’s been cut and milled into the desired dimensions. The wood is then placed inside a large cylindrical container known as a retort. Inside this retort, all the air is removed to create a vacuum. This step is critical because it helps to ensure that the treatment solution penetrates deeply into the wood.
Next, under high pressure, a solution containing chemicals to protect against insects, rot, and decay is forced into the retort. The combination of vacuum and pressure makes sure that this protective solution saturates all the way through the wood fibers rather than just on the surface. This deep penetration is what provides PT wood with its distinctive qualities of durability and resistance to decay.
Once the wood is thoroughly soaked in the chemical solution, it’s removed from the retort. It’s then left to dry until it reaches its original weight before being treated. The drying process can take several weeks but is crucial to ensure that the protective chemicals are permanently fixed in the wood. Once dried, PT wood is ready for use in any application where resistance to rot and insects would be beneficial.
It’s important to note that despite its chemical treatment, PT wood can still be cut, drilled, and sanded just like untreated wood. However, due to potential exposure to the treatment chemicals, it’s recommended to use gloves when handling freshly treated PT wood and always work in a well-ventilated area. A dust mask should be worn when cutting or sanding PT wood to avoid inhaling any wood dust that might contain residual treatment chemicals.
In summary, the PT wood process involves vacuum sealing the wood and infusing it with a chemical protective solution under high pressure, followed by a drying period. This gives the wood its trademark durability and resistance to decay, making it an ideal choice for outdoor construction projects. Now that you understand what PT wood is and how it’s made, you can make informed decisions about your next DIY project!
