Using Pressure Treated Wood for Durable Furniture

Considering the durability and sustainability aspects of wood, it's no surprise that many furniture manufacturers and DIY enthusiasts alike are turning to pressure treated wood. This article explores the benefits, applications, and best practices of using pressure treated wood for furniture.

Pressure treatment is a process that involvess soaking lumber in preservatives to protect it from rot, decay, and insect damage. This not only extends the lifespan of the wood but also makes it ideal for outdoor use, expanding the possibilities for furniture design and placement.

Understanding Pressure Treated Wood

Pressure treated wood is created by subjecting lumber to a vacuum and pressure cycle, forcing preservatives deep into the wood. This ensures comprehensive protection throughout the material, providing lasting resistance against harsh environmental elements.

The most common preservatives used are alkaline copper quaternary (ACQ) and copper azole. These chemicals are safe for humans and pets once dry but can cause skin irritation if handled before drying. Always ensure you follow safety guidelines when working with pressure treated wood.

Types of Pressure Treated Wood

Two primary types of pressure treated wood are available: grounded contact and above ground. Ground contact lumber is designed for direct contact with the ground or constant moisture exposure, making it perfect for outdoor furniture bases, posts, or decking. Above ground lumber is suitable for furniture that isn't in direct contact with the ground, like chairs, tables, or stools.

Each type of pressure treated wood carries a different warranty, usually ranging from 15 to 30 years, depending on the preservative used and how the wood is applied. There's also a new generation of pressure treated wood, labeled as CA (Copper Azole), which provides longer warranties and eco-friendly credentials.

Pressure Treated Wood Advantages

Durability is the primary advantage of pressure treated wood. When properly maintained, furniture made from this material can last decades, saving you money and time in replacements. Additionally, pressure treated wood can be used in a wider range of environments than untreated wood, including exposed outdoor areas, basement interiors, and other damp or moist conditions.

Moreover, using pressure treated wood supports sustainable forestry practices. Many manufacturers ensure their treated wood comes from responsibly harvested, certified forests. This means that by choosing pressure treated wood, you're encouraging healthy, long-term forest management.

Using Pressure Treated Wood in Furniture

Pressure treated wood's durability and versatility open up a world of furniture designs. Here are some ideas and best practices to keep in mind.

Remember, while the pressure treatment protects the wood, it doesn't shield it from sunlight. To avoid fading or cracking, apply a sealant or paint to your pressure treated wood furniture, especially if it's intended for full sun exposure. Regularly inspect and maintain your furniture to ensure its longevity.

Outdoor Furniture

Pressure treated wood is a fantastic choice for outdoor furniture like benches, picnic tables, or swing sets. Its resistance to rot and decay makes it ideal for environments that are exposed to varying weather conditions and humidity levels. Just ensure you allow the wood to fully dry before applying a sealant or paint.

When designing outdoor furniture, consider using robust, chunky styles that can withstand heavy use. You can also create a cohesive look by incorporating pressure treated wood into your outdoor living space, using it for planters, fencing, or decking as well.

Indoor Furniture

While not exempt from moisture exposure, indoor environments are generally less harsh than outdoor ones. Therefore, you can use pressure treated wood indoors for bases of cabinets, bookcases, or countertops that could be exposed to moisture. You can also use it for built-in furniture that might be difficult to move for repairs or maintenance.

To maintain a consistent look and finish, treat all indoor furniture components with the same stain or paint. If you're using it for pieces that may come into contact with food, ensure the preservative used is food-safe by checking the manufacturer's guidelines.

The versatility and durability of pressure treated wood make it an excellent choice for both indoor and outdoor furniture. By understanding its properties and best practices, you can create long-lasting, stylish pieces that enhance your living space. So, don't hesitate to explore the many possibilities of pressure treated wood for your next furniture project.
