The Process of Pressure Treating Wood
Let’s delve into the process of pressure treating wood to understand fully: ‘What is pressure treated wood?’ This process essentially involves infusing chemicals into the wood to protect it against insects, decay, and other environmental hazards. The result is a durable and strong piece of lumber that is ideal for outdoor applications such as decks, fences, and playground equipment. But how exactly is this accomplished?
The initial step in the pressure treatment process involves sorting the wood based on its type and size. This enables manufacturers to ascertain which specific kind of pressure treatment would be most beneficial for the batch.
Subsequently, the sorted wood is loaded into a large cylindrical tank also known as a retort. Before applying any chemical treatment, the wood must be properly conditioned. Therefore, a vacuum cycle is initiated inside the retort to remove air from the wood’s cells, which makes it more responsive to the treatment.
Next follows the impregnation stage where an appropriate preservative solution is introduced into the cylinder under high pressure. The pressure forces the liquid deep into the core of each piece of lumber. This ensures that the wood is thoroughly protected against any future decay or insect attacks.
Following this, a final vacuum cycle removes any excess preservative from the exterior of the wood and sends it back to storage for reuse in future batches. After this stage, the treated timber is removed from the retort and left in a covered area to dry naturally or sent through a kiln for accelerated drying.
This entire process changes not just the surface but also the internal structure of the wood, making it more robust and resilient to elements. However, it’s important to remember that not all woods respond equally well to this treatment. Softwoods like pine and fir are more permeable and therefore more suitable for pressure treatment than hardwoods.
In conclusion, when we ask, ‘What is pressure treated wood?’ we’re referring to a type of lumber that undergoes a unique processing method. It involves heavy-duty machinery and specific chemicals to make the wood more durable and resistant to decay and pests, thereby significantly extending its lifespan and overall utility.

Scent
Pressure treated wood carries a distinct chemical odor. If you get close enough, you could detect this smell which is different from untreated or naturally aromatic woods like cedar or pine.
In conclusion, identifying pressure-treated wood involves keen observation of its color, appearance, scent, and the presence of an end tag. However, if you are still unsure, it’s best to inquire directly from your lumber supplier.
Caring for Pressure Treated Wood
So, what is pressure treated wood? This is wood that has been treated with chemicals to enhance its resistance against decay, termites, and other damaging elements. However, to maximize its lifespan and maintain its appearance, regular care and maintenance are crucial.
One of the first things you should do after installing pressure treated wood is to let it dry properly. This can take several weeks but will ensure the wood is ready to absorb a sealant or stain evenly. Once dry, apply a high-quality sealant that includes a water-repellant to further protect the wood from moisture. This treatment will shield your wood from harmful UV rays and limit cracking or splitting from weather-related expansion and contraction.
It’s essential to reapply sealant every one to three years based on the level of exposure to weather elements. The easiest way to determine when it’s time for another treatment is if water stops beading up on the surface. A simple rule of thumb is if the water absorbs into the wood, it’s time for another treatment.
When it comes to cleaning your pressure treated wood, ordinary soap and water will usually do the trick. Avoid using harsh chemicals or pressure washers as they can damage the wood’s surface. For tougher stains, a mild deck cleaner can be used but always perform a spot check first.
Even though pressure treated wood is resistant to insects and rot, it’s not invulnerable. Regularly inspect your wood for signs of damage such as splintering, warping, or insect activity. If detected early, these issues can be managed before they become more serious problems.
Lastly, when cutting or drilling into pressure-treated wood, remember to apply a coat of end-cut preservative on the exposed ends to protect against rot and insect damage. This is crucial as the treatment may not fully penetrate the wood’s core, leaving the inner section susceptible to damage.
By following these simple care and maintenance steps, you can extend the longevity and maintain the beauty of your pressure-treated wood, ensuring it remains a durable and attractive addition to your home for years to come.
Environmental Impact of Pressure Treated Wood
Pressure treated wood is a type of wood that has been treated with chemicals to make it resistant to insects, fungi, and other environmental factors that can cause decay.
