Anti-corrosion wood decoration balcony terrace should pay attention to the problem

Anti-corrosion wood is an excellent choice for outdoor projects like decks, patios, and balconies. It is typically made from pine and treated with preservatives to resist rot, insects, and moisture. To ensure its longevity, it's important to handle and install it properly.

When installing anti-corrosion wood on a balcony or terrace, leave some space between the boards and the ground to allow for proper airflow. This helps prevent moisture buildup and makes cleaning easier. If any debris falls into the gaps, it can be easily removed. Also, maintain small gaps (around 5-10mm) between the planks for better drainage and aesthetics.

Proper storage is crucial before installation. Keep the wood in a dry, well-ventilated area and avoid direct sunlight, which can degrade the protective treatment. During construction, try to use the wood in its original dimensions as much as possible. If cutting or drilling is necessary, make sure to reapply CCA preservative to the cut ends to maintain its durability and protection against decay.

Since anti-corrosion wood is a semi-finished product, you may need to sand the surface after installation to achieve a smoother finish. It’s also recommended to reduce the wood’s moisture content to below 20% for optimal performance. For added protection, consider applying an outdoor wood sealant or coating after cleaning the surface. Make sure the color of the coating is fully mixed for a uniform look.

If you plan to paint or apply a protective finish, avoid walking on the surface or placing heavy objects on it for at least 48 hours. This allows the coating to cure properly and form a strong protective layer. For even better stain resistance, you might want to apply a special outdoor wood oil treatment after the initial coating.

When building a terrace, using longer planks can help reduce the number of joints, improving both the appearance and structural integrity. Always use hot-dip galvanized fasteners or stainless steel hardware for all connections to prevent rust and ensure long-term stability.
