AC2® CedarTone pressure treated lumber uses #1 grade southern yellow pine to provide optimum strength and appearance on any outdoor project left exposed to the elements. Treated lumber is a renewable building product that is safe for use in any application, including those around pets, playsets, and vegetable gardens. AC2® CedarTone lumber is prefinished - infused with a rich color, similar to coastal western cedar, which provides pleasing aesthetic performance for the first two years following completion of the outdoor project. After several weeks of outdoor exposure, the product will change to a lighter, more natural color. AC2® CedarTone Premium treated wood products will maintain this cedar-like color when natural cedar wood has faded to a gray color. Wood is a natural product with many unique characteristics and properties. While wood's strength and workability make it great for general construction and building projects, other inherent characteristics make it subject to checks or splits and warping or twisting. In addition, the actual size is almost always smaller than the nominal (common name) size and may vary slightly depending on the moisture content.
