WonderBoard Lite is designed to address the physical demands of handling traditional, heavy cement board. It is up to 20% lighter, which significantly eases the installation process, especially in vertical, overhead, or tight-space applications. Despite its reduced weight, it offers the structural integrity needed to support the weight of heavy tile and stone installations. The board is made from inorganic, cementitious materials that are inherently resistant to moisture, mold, and rot, providing a long-term foundation that will not fail in damp environments like bathrooms or kitchens. This product is suitable for interior residential and commercial projects and can be installed over wood or steel studs and on concrete subfloors. It is specifically engineered to ensure an excellent bond with thin-set mortars, which is crucial for preventing debonding. When installing, you must follow the manufacturer’s guidelines regarding fastener spacing, fastener type, and the requirement for mortar or mesh tape at joints. By using a stable, moisture-resistant substrate like WonderBoard Lite, you create a system that helps prevent common issues such as grout cracking and tile failure caused by substrate movement or moisture infiltration.
