GenStone artificial siding only requires a clean, dry substrate such as OSB, plywood, concrete, or existing siding provided the surface is flat such as RB&B, Textured 1-11, or any hardboard panel siding. The panels are easily applied to almost any flat surface. There are no strapping or starter strips required unless you are installing or purchasing the product in Canada. Simply use a polyurethane-safe adhesive (PL200 or PL300) and attach it with concrete screws (Tapcons).
