How to Choose the Best Treated Wood Decking

Understanding Treatment Levels

Treated wood decking is infused with preservatives to protect against rot, decay, and insect infestation. The level of treatment is crucial for its intended use and environment. For ground contact applications, such as posts set directly into the soil, opt for wood rated for 'ground contact.' For above-ground decks, 'above ground' rated lumber is sufficient. Higher treatment levels generally offer greater protection but may come at a higher cost.

Wood Species Considerations

While pine is the most common treated wood, other species offer different benefits. Cedar and redwood naturally contain oils that provide some resistance to decay and insects, even before treatment. However, these are typically more expensive options. Consider the climate you live in and the specific demands you'll place on your deck when choosing a species, balancing cost with desired durability and aesthetics.

Fastener Compatibility

The chemicals used in wood preservatives can be corrosive to certain metals. It is essential to use fasteners specifically designed for treated lumber, often labeled as "ACQ compatible" or "corrosion-resistant." Using the wrong type of screws or nails can lead to premature rusting, staining, and structural weakening of your deck. Always check fastener packaging to ensure compatibility.

Frequently Asked Questions

What is the difference between above-ground and ground-contact treated lumber?
Above-ground rated lumber is suitable for decking boards and railings where the wood is not in direct contact with soil. Ground-contact rated lumber has a higher concentration of preservatives and is designed to withstand constant moisture and potential insect activity when in direct contact with the earth, such as for posts or support beams.
How long does treated wood decking typically last?
With proper installation and regular maintenance, treated wood decking can last between 10 to 25 years. Factors like climate, exposure to sunlight and moisture, and the quality of the initial treatment and installation will influence its lifespan.
Do I need to seal or stain treated wood?
While treated wood is protected against rot and insects, sealing or staining is recommended for aesthetic reasons and added protection against UV rays and moisture. Sealing helps prevent cracking and warping, and staining allows you to achieve your desired color and finish.
Can treated wood be used for outdoor furniture?
Yes, treated wood is a popular choice for outdoor furniture due to its durability and resistance to the elements. Ensure the wood is rated appropriately for its intended use and allow it to dry thoroughly before applying any finishes.
