Treatment Specifications (ACQ)     Fastener and Hardware Recommendations NatureWood preserved wood products are designed for long-term performance in outdoor applications and, therefore, require high quality, corrosion-resistant nails, screws, and other fasteners. Warning - Certain metal products (including fasteners, hardware and flashing) may corrode when in direct contact with NatureWood products. To prevent premature corrosion and failure it is important to follow the recommendations of the manufacturers for all metal products. Direct contact of NatureWood preserved wood with aluminum is not recommended.   NatureWood Weathering Information Freshly treated NatureWood products begin with a familiar greenish color and will over time turn to a tan/brown color upon exposure to sunlight. As with most wood products, NatureWood products will eventually fade to gray over time.   NatureWood Treatment Specifications   Table 1.
