Care and Maintenance for treated wood products

Apply a weather-resistant finish – Any exposed wood, pressure treated or not, should be protected with a high-quality water repellent finish to reduce warping, checking, and splitting. Wait until the surface is completely dry.

Fastener Information – Our preserved wood products are designed for long-term performance in outdoor applications and, therefore, require high quality, corrosion resistant nails, screws, and hardware. Use hot-dip galvanized (conforming to ASTM Standards: ASTM-A153 for hot-dip fasteners and ASTM-A653, Coating Designation G-185 for hot-dip connectors and sheet products), stainless steel, or other fasteners and hardware as recommended by the hardware manufacturer. Direct contact of preserved wood with aluminum fasteners is not recommended.

Drill pilot holes – Drill pilot holes, especially when nailing or screwing near the edge or end of a board. Pilot holes will help minimize splitting.

Deck board spacing – During construction, should the wood become wet, butt deck boards together. As drying occurs, some shrinkage can be expected. If the wood is dry, allowing for shrinkage is not necessary.
