Outdoor Furniture Pressure Treated Wood

When choosing materials for outdoor furniture, pressure-treated wood is a popular and cost-effective option. It offers several advantages over untreated wood, making it a suitable choice for decks, patios, and other outdoor structures.

What is Pressure-Treated Wood?

Pressure-treated wood is lumber that has been subjected to a process called pressure treatment. In this process, chemical preservatives are forced into the wood under high pressure, penetrating deeply into the fibers. These preservatives protect the wood from rot, decay, and termite infestation.

Advantages of Pressure-Treated Wood

Pressure-treated wood offers several benefits for outdoor furniture:

Durability: The preservatives used in pressure treatment make the wood highly resistant to rot, decay, and insects, extending its lifespan.
Low Maintenance: Unlike untreated wood, pressure-treated wood requires minimal maintenance. It does not need to be sealed or painted regularly, saving you time and effort.
Cost-Effectiveness: Pressure-treated wood is relatively inexpensive compared to other materials like cedar or teak, making it a budget-friendly choice.
Versatility: Pressure-treated wood can be used in various outdoor applications, including decks, patios, benches, and planters.

Types of Pressure-Treated Wood

There are two main types of pressure-treated wood available:

ACQ (Alkaline Copper Quaternary): This type of treatment uses copper-based preservatives, which are effective against rot and decay but less resistant to termites.
CCA (Chromated Copper Arsenate): This treatment uses chromium, copper, and arsenic preservatives, which provide broader protection against rot, decay, and termites.

Considerations for Using Pressure-Treated Wood

While pressure-treated wood offers many benefits, there are some considerations to keep in mind:

Toxicity: CCA-treated wood contains arsenic, which is a known carcinogen. It should not be used in areas where it may come into contact with food or water.
Environmental Impact: The chemicals used in pressure treatment can be harmful to the environment if not disposed of properly.
Discoloration: Pressure-treated wood may develop a greenish tint over time due to the copper preservatives. Some people find this discoloration undesirable.

Conclusion

Pressure-treated wood is a durable, cost-effective, and versatile option for outdoor furniture. Its resistance to rot, decay, and insects makes it a suitable choice for decks, patios, and other structures exposed to the elements. However, it is important to consider the potential toxicity and environmental impact before using pressure-treated wood in certain applications.
