There are several great reasons to choose our treated lumber.

The NatureWood systems are based on the well-established effectiveness of copper combined with a co-biocide, and are applied to wood by pressure treatment. All our incised treated wood products are certified for ground contact and fresh water contact applications for projects such as decks, fences and landscaping.

Care and Maintenance

Apply a weather-resistant finish – Any exposed wood, pressure treated or not, should be protected with a high quality water repellent finish or stain with water repellent to help reduce warping, checking, and splitting. Application of a quality clear water repellent or semitransparent stain, which contains water repellent, will help minimize the cycles of moisture take-up and loss the wood goes through outdoors. First, determine if your NatureWood product has been pressure treated with a factory applied water repellent by looking at the end tag. If not factory water repellent treated, thoroughly clean your project with a deck cleaning product. Clear water repellent can be immediately applied to your deck or other project. If you choose to use a semitransparent stain which contains a water repellent, you need to first check that your project is surface dry. Either wait until the surface is dry or immediately apply clear water repellent and wait approximately 8 weeks and then apply your chosen color of semitransparent stain. Water repellent should be reapplied every 12 to 18 months, stains – every 24 to 36 months.

Fastener Information – NatureWood 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 NatureWood 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.

When appearance permits, attach boards bark side up – As a general rule, attach boards bark side up (annual rings arc upward) to reduce cupping; however, the best face should be placed up when a defect of the wood is apparent. Fasten thin boards to thicker boards to maintain structural integrity.
