S4S KD lumber refers to "Surfaced Four Sides" and "Kiln Dried" lumber. This type of wood is planed on all four sides to achieve a smooth finish and is dried in a kiln to reduce moisture content, making it less prone to warping or splitting. S4S KD lumber is commonly used in woodworking and construction for projects where a finished appearance and stability are important. It is often utilized for furniture, cabinetry, and trim work.
Smooth 4 sides. All four sides have been planed.
Board feet is the unit measure of rough lumber. Linear feet is the unit measure of S4S lumber. (smooth 4 sides)
it is a superior wood for decking, staying smooth and splinter free for years. Also, it looks much better than treated pine.
To calculate the amount of lumber needed for a 12x15 deck, first determine the total square footage, which is 180 square feet (12 feet x 15 feet). The amount of lumber required will depend on the type of decking material and the spacing of the boards. For standard decking boards that are 6 inches wide, you would typically need about 300 linear feet of decking to cover that area, accounting for gaps and cuts. Always consult local building codes and consider additional lumber for the frame and support structure.
Plastic lumber may be used for building outdoor decking areas or other recreational structures. It may also be used for molding, trim work or as a general replacement for many wood applications.
To maintain treated decking lumber for longevity and durability, regularly clean it with a mild detergent and water, inspect for any damage or rot, apply a water-resistant sealant every 1-2 years, and avoid using harsh chemicals or pressure washers that can damage the wood.
